In presenting to the public this English version of Louis Figuier's interesting work on Reptiles and Birds, I beg to state that where alterations and additions have been made, my object has been that the style and matter should be suited to the present state of general knowledge, and that all classes should be able to obtain useful information and amusement from the pages which I have now the honour and pleasure of presenting to them.
On commencing my undertaking I was not aware of the immensity of the labour to be done, and fear that I must have relinquished my arduous task but for the kind encouragement of Frank Buckland, Esq., Inspector of Salmon Fisheries, and Henry Lee, Esq., F.L.S., F.G.S., &c., to both of whom I take this opportunity of returning my sincere thanks.

Phasianus cristatus indicus, in page 448, should be attributed to Brisson, not Latham.
The synonym for Ring Pigeon, in page 448, should be Columba palumbus.
Woodcut 182 represents the Stock Dove, erroneously named Wood Pigeons in page 450. xvi 1
REPTILES AND BIRDS.
There is little apparent resemblance between the elegant feathered warbler which makes the woods re-echo to its cheerful song, and the crawling reptile which is apt to inspire feelings of disgust when the more potent sensation of terror is absent—between the familiar Swallow, which builds its house of clay under the eaves of your roof, or the warbler whose nest, with its young progeny, carefully watched by the father of the brood in the silent watches of the night, is now threatened by the Serpent which has glided so silently into the bush, its huge mouth already open to swallow the whole family, while the despairing and fascinated parents have nothing but their slender bills to oppose to their formidable foe. "Placed side by side," says Professor Huxley, "a Humming-bird and a Tortoise, or an Ostrich and a Crocodile, offer the strongest contrast; and a Stork seems to have little but its animality in common with the Snake which it swallows." Nevertheless, unlike as they are in outward appearance, there is sufficient resemblance in their internal economy to bring them together in most attempts at a classification of the Animal Kingdom. The air-bladder which exists between the digestive canal and kidneys in some fishes, becomes vascular with the form and cellular structure of lungs in reptiles; the heart has two auricles, the ventricle in most is imperfectly divided, and more or less of the venous blood is mixed with the arterial which circulates over the body; but retaining their gills and being therefore transitional in structure, they are also cold-blooded. In 2 birds, the lungs are spongy, the cavity of the air-bags becoming obliterated by the multiplication of vascular cellules; the heart is four-chambered, transmitting venous blood to the lungs, and pure arterial blood to the body; the temperature is raised and maintained at 90° to 100° Fahr.
Thus Reptiles, like Birds, breathe the common air by means of their lungs, but respiration is much less active. "Although," remarks Professor Owen, "the heart of Birds resembles in some particulars that of Reptiles, the four cavities are as distinct as in the Mammalia, but they are relatively stronger, their valvular mechanism is more perfect, and the contractions of this organ are more forcible and frequent in birds, in accordance with their more extended respiration and their more energetic muscular action." It is true, as Professor Huxley informs us, that the pinion of a bird, which corresponds with the human hand or the fore paw of a reptile, has three points representing three fingers: no reptile has so few.1 The breast-bone of a bird is converted into membrane-bone: no such conversion takes place in reptiles. The sacrum is formed by a number of caudal and dorsal vertebræ. In reptiles the organ is constituted by one or two sacral vertebræ.
In other respects the two classes present many obvious differences, but these are more superficial than would be suspected at first glance. And Professor Huxley believes that, structurally, "reptiles and birds do really agree much more closely than birds with mammals, or reptiles with amphibians."
While most existing birds differ thus widely from existing reptiles, the cursorial or struthious genera, comprising the Ostrich, Nandou, Emu, Cassowary, Apteryx, and the recently extinct Dinornis of New Zealand, come nearer to the reptiles in structure than any others. All of these birds are remarkable for the shortness of their wings, the absence of a crest or keel upon the breast-bone, and some peculiarities of the skull, which render them more peculiarly reptilian. But the gap between reptiles and birds is only slightly narrowed by their existence, and is somewhat unsatisfactory to those who advocate the development theory, which asserts that all animals have proceeded, by gradual modification, from a common stock. 3
Traces had been discovered in the Mesozoic formations of certain Ornitholites, which were too imperfect to determine the affinities of the bird. But the calcareous mud of the ancient sea-bottom, which has hardened into the famous lithographic slate of Solenhofen, revealed to Hermann von Meyer, in 1861, first the impression of a feather, and, in the same year, the independent discovery of the skeleton of the bird itself, which Von Meyer had named Archæopteryx lithographicus. This relic of a far-distant age now adorns the British Museum.
The skull of the Archæopteryx is almost lost, but the leg, the foot, the pelvis, the shoulder-girdle, and the feathers, as far as their structure can be made out, are completely those of existing birds. On the other hand, the tail is very long. Two digits of the manus have curved claws, and, to all appearance, the metacarpal bones are quite free and disunited, exhibiting, according to Professor Huxley, closer approximation to the reptilian structure than any existing bird. Mr. Evans has even detected that the mandibles were provided with a few slender teeth.
On the other hand, the same writer points out certain peculiarities in the single reptile found also among the Solenhofen slates, which has been described and named Compsognathus longipes by the 4 late Andreas Wagner. This reptile he declares "to be a still nearer approximation to the missing link between reptiles and birds," thus narrowing the gap between the two classes.
While we think it proper to point to these structural resemblances of one class of the animal creation to others very different in their external appearance, it is necessary to guard ourselves and our readers from adopting the inferences sometimes deduced from them; that "these infinitely diversified forms are merely the final terms in an immense series of changes which have been brought about in the course of immeasurable time, by the operation of causes more or less similar to those which are at work at the present day." Domestication and other causes have no doubt produced changes in the form of many animals; but none from which this inference can be drawn, except in the imagination of ingenious men who strain the facts to support a preconceived hypothesis. In spite of the innumerable forms which the pigeon assumes by cross-breeding and domestication, it still remains a pigeon; the dog is still a dog, and so with other animals. Nor does it seem to us to be necessary, or calculated to advance our knowledge in natural history, to form theories which can only disturb our existing systems without supplying a better. Systems are necessary for the purpose of arrangement and identification; but it should never be forgotten that all classifications are artificial—a framework or cabinet, into the partitions of which many facts may be stowed away, carefully docketed for future use. "Theories," says Le Vaillant, "are more easily made and more brilliant probably than observations; but it is by observation alone that science can be enriched." A bountiful Creator appears to have adopted one general plan in the organization of all the vertebrate creation; and, in order to facilitate their study, naturalists have divided them into classes, orders, and genera, formed on the differences which exist in the structure of their vital functions. The advantages of this are obvious, but it does not involve the necessity of fathoming what is unfathomable, of explaining what is to man inexplicable in the works of God.2

In previous volumes of this series3 we have endeavoured to give the reader some general notions of the form, life, and manners of the branches of the animal kingdom known as Zoophytes, Mollusca, Articulata, and Pisces. We now continue the superior sub-kingdom (to which the fishes also belong) of the Vertebrated Animals, so called from the osseous skeleton which encircles their bodies, in which the vertebral column, surmounted by the cranium, its appendage, forms the principal part.
The presence of a solid frame in this series of animals admits of their attaining a size which is denied to any of the others. The skeleton being organized in such a manner as to give remarkable vigour and precision to all their movements.
In the vertebrated animals the nervous system is also more developed. There is, consequently, a more exquisite sensibility in them than in the classes whose history we have hitherto discussed. They possess five senses, more or less fully developed, a heart, a circulation, and their blood is red.
We have now to deal with a class advanced above that of fishes, that of Reptilia, which is divided as follows:—
Animals having ribs or processes, or short, slight, and free vertebræ, forming a series of separate centrums, deeply cupped at both ends, one of which is converted by ossification in the mature animal into a ball, which may be the front one, as in the Surinam Toad, Pipa, or the hind ones in the Frogs and Toads, Rana. The skin is nude, limbs digitate, gills embryonal,—permanent in some, in most lost in metamorphosis,—to be succeeded by pulmonary respiration,—or both; a heart with one ventricle and two auricles. They consist of:—
I. Ophiomorpha. | |
---|---|
Cæciliadæ or Ophiosomæ. | |
II. Icthyomorpha. | |
Proteidæ or Sirens, Proteus, Newts, and Salamanders.6 | |
III. Theriomorpha. | |
Aglosa | Pipa or Surinam Toads. |
Ranidæ | Frogs. |
Hylidæ | Tree Frogs. |
Bufonidæ | Toads. |
Distinguished by the double shield in which their bodies are enclosed, whether they are terrestrial, fresh-water, or marine.
The Turtles, Chelonia, have the limbs natatory. | ||
Mud Turtles, Trionyx, | } limbs amphibious. | |
Terrapens, Emys, | ||
Tortoises, Testudo, limbs terrestrial. |
Having a single transverse process on each side, single-headed ribs, two external nostrils, eyes with movable lids; body covered with horny, sometimes bony, scales.
Lacerta—the Monitors, Crocodiles, Lizards; having ambulatory limbs.
Anguis—Ophisaurus, Bimanus, Chalcides, Seps; limbs abortive; no sacrum.
Having numerous vertebræ with single-headed hollow ribs, no visible limbs, eyelids covered by an immovable transparent lid; body covered by horny scales. It includes:—
Viperinæ—the Vipers and Crotalidæ. |
Colubrinæ—the Colubers, Hydridæ, and Boidæ. |
Teeth in a single row, implanted in distinct sockets; body depressed, elongated, protected on the back by solid shield; tail longer than the trunk, compressed laterally, and furnished with crests above. The several families are:—
Crocodilidæ—the Gavials, Mecistops, Crocodiles. |
Alligatoridæ—Jacares, Alligators, Caiman.4 |

Those geographers who divide the world into land and sea overlook in their nomenclature the extensive geographical areas which belong permanently to neither section—namely, the vast marshy regions on the margins of lakes, rivers, and ponds, which are alternately deluged with the overflow of the adjacent waters, and parched and withering under the exhalations of a summer heat; regions which could only be inhabited by beings capable of living on land or in water; beings having both gills through which they may breathe in water, and lungs through which they may respire the common air. The first order of reptiles possesses this character, and hence its name of Amphibia, from αμφιβιος, having a double life.
The transition from fishes to reptiles is described by Professor Owen, with that wonderful power of condensation which he possesses, in the following terms:—"All vertebrates during more or less of their developmental life-period float in a liquid of similar specific gravity to themselves. A large proportion, constituting the lowest organised and first developed forms of this province, exist and breathe in water, and are called fishes. Of these a few retain the primitive vermiform condition, and develop no limbs; in the rest they are 'fins' of simple form, moving by one joint upon the body, rarely adapted for any other function than the impulse or guidance of the body through the water. The shape of the body is usually adapted for moving with least resistance through the liquid medium. The surface of the body is either smooth and lubricous or it is smoothly covered with overlapping scales; it is rarely defended by bony plates, or roughened by tubercles. 8 Still more rarely it is armed with spines." Passing over the general economy of fishes we come to the heart. "The heart," he tells us, "consists of one auricle receiving the venous blood, and one ventricle propelling it to the gills or organs submitting that blood in a state of minute subdivisions to the action of aërated water. From the gills the aërated blood is carried over the entire body by vessels, the circulation being aided by the contraction of the surrounding muscles."
The functions of gills are described by the Professor with great minuteness. "The main purpose of the gills of fishes," he says, "being to expose the venous blood in this state of minute subdivision to streams of water, the branchial arteries rapidly divide and sub-divide until they resolve themselves into microscopic capillaries, constituting a network in one plane or layer, supported by an elastic plate, covered by a tesselated and non-ciliated epithelium. This covering and the tunics of the capillaries are so thin as to allow chemical interchange and decomposition to take place between the carbonated blood and the oxygenated water. The requisite extent of the respiratory field of capillaries is gained by various modes of multiplying the surface within a limited space." "Each pair of processes," he adds, "has its flat side turned towards contiguous pairs, and the two processes of each pair stand edgeway to each other, being commonly united for a greater or less extent from their base; hence Cuvier describes each pair as a single bifurcated plate, or 'feuillet.'"
The modification which takes place in the respiratory and other organs in Reptilia, is described in a few words. "Many fishes have a bladder of air between the digestive canal and the kidneys, which in some communicate with an air-duct and the gullet; but its office is chiefly hydrostatic. When on the rise of structure this air-bladder begins to assume the vascular and pharyngeal relations with the form and cellular structure of lungs, the limbs acquire the character of feet: at first thread-like and many jointed, as in the Lepidosiren; then bifurcate, or two-fingered, with the elbow and wrist joints of land animals, as in Amphiuma; next, three-fingered, as in Proteus, or four-fingered, but reduced to the pectoral pair, as in Siren."
In all reptiles the blood is conveyed from the ventricular part 9 of the heart, really or apparently, by a single trunk. In Lepidosiren the veins from the lung-like air-bladders traverse the auricle which opens directly into the ventricle. In some the vein dilates before communicating with the ventricle into a small auricle, which is not outwardly distinct from the much larger auricle receiving the veins of the body. In Proteus the auricular system is incomplete. In Amphiuma the auricle is smaller and less fringed than in the Sirens, the ventricle being connected to the pericardium by the apex as well as the artery. This forms a half spiral turn at its origin, and dilates into a broader and shorter bulb than in the Sirens.
"The pulmonic auricle," continues the learned Professor, "thus augments in size with the more exclusive share taken by the lungs in respiration; but the auricular part of the heart shows hardly any outward sign of its diversion in the Batrachians. It is small and smooth, and situated on the left, and in advance of the ventricle in Newts and Salamanders. In Frogs and Toads the auricle is applied to the base of the ventricle, and to the back and side of the aorta and its bulb."
In the lower members of the order, the single artery from the ventricle sends, as in fishes, the whole of the blood primarily to the branchial organs, during life, and in all Batrachians at the earlier aquatic periods of existence. In the Newt three pairs of external gills are developed at first as simple filaments, each with its capillary loop, but speedily expanding, lengthening, and branching into lateral processes, with corresponding looplets; those blood-channels intercommunicating by a capillary network. The gill is covered by ciliated scales, which change into non-ciliated cuticle shortly before the gills are absorbed. In the Proteus anguinus, three parts only of branchial and vascular arches are developed, corresponding with the number of external gills. In Siren lacertina the gills are in three pairs of branchial arches, the first and fourth fixed, the second and third free, increasing in size according to their condition.
The Amphibia, then, have all, at some stage of their existence, both gills and lungs co-existent: respiring by means of branchiæ or gills while in the water, and by lungs on emerging into the open air. 10
All these creatures seem to have been well known to the ancients. The monuments of the Egyptians abound in representations of Frogs, Toads, Tortoises, and Serpents. Aristotle was well acquainted with their form, structure, and habits, even to their reproduction. Pliny's description presents his usual amount of error and exaggeration. Darkness envelops their history during the middle ages, from which it gradually emerges in the early part of the sixteenth century, when Belon and Rondiletius in France, Salviani in Italy, and Conrad Gesner in Switzerland, devoted themselves to the study of Natural History with great success. In the latter part of the same century Aldrovandi appeared. During fifty years he was engaged in collecting objects and making drawings, which were published after his death, in 1640, edited by Professor Ambrossini, of Bologna, the Reptiles forming two volumes. In these volumes, twenty-two chapters are occupied by the Serpents. But the first arrangement which can be called systematic was that produced by John Ray. This system was based upon the mode of respiration, the volume of the eggs, and their colour.
Numerous systems have since appeared in France, Germany, and England; but we shall best consult our readers' interest by briefly describing the classification adopted by Professor Owen, the learned Principal of the British Museum, in his great work on the Vertebrata.
The two great classes Batrachians and Reptiles, include a number of animals which are neither clothed with hair, like the Mammalia, covered with feathers like the birds, nor furnished with swimming fins like fishes. The essential character of reptiles is, that they are either entirely or partially covered with scales. Some of them—for instance, Serpents—move along the ground with a gliding motion, produced by the simple contact and adhesion of the ventral scales with the ground. Others, such as the Tortoises, the Crocodiles, and the Lizards, move by means of their feet; but these, again, are so short, that the animals almost appear to crawl on the ground—however swiftly, in some instances. The locomotive organs in Serpents are the vertebral column, with its muscles, and the stiff epidermal scutes crossing the under surface of the body. "A Serpent may, however, be 11 seen to progress," says Professor Owen, "without any inflection, gliding slowly and with a ghost-like movement in a straight line, and if the observer have the nerve to lay his hand flat in the reptile's course, he will feel, as the body glides over the palm, the surface pressed as it were by the edges of a close-set series of paper knives, successively falling flat after each application." Others of the class, such as the Tortoises, Crocodiles, and Lizards, move by the help of feet, which are generally small and feeble—in a few species being limited to the pectoral region, while in most both pairs are present. In some, as in various Lizards, the limbs acquire considerable strength.
There is one genus of small Lizards, known as the Dragons, Draco, whose movements present an exception to the general rule. Besides their four feet, these animals are furnished with a delicate membranous parachute, formed by a prolongation of the skin on the flanks and sustained by the long slender ribs, which permits of their dropping from a considerable height upon their prey.
Batrachians, again, differ from most other Reptilia by being naked: moreover, most of them undergo certain metamorphoses; in the first stage of their existence they lead a purely aquatic life, and breathe by means of gills, after the manner of fishes. Young Frogs, Toads, and Salamanders, which are then called tadpoles, have, in short, no resemblance whatever to their parents in the first stage of their existence. They are little creatures with slender, elongated bodies, destitute of feet and fins, but with large heads, which may be seen swimming about in great numbers in stagnant ponds, where they live and breathe after the manner of fishes. By degrees, however, they are transformed: their limbs and air-breathing lungs are gradually developed, then they slowly disappear, and a day arrives when they find themselves conveniently organized for another kind of existence; they burst from their humid retreat, and betake themselves to dry land. "The tadpole meanwhile being subject to a series of changes in every system of organs concerned in the daily needs of the coming aërial and terrestrial existence, still passes more or less time in water, and supplements the early attempt at respiration by pullulating loops and looplets of capillaries from the branchial vessels." (Owen.) 12
Nevertheless, they do not altogether forget their native element; thanks to their webbed feet, they can still traverse the waters which sheltered their infancy; and when alarmed by any unusual noise, they rush into the water as a place of safety, where they swim about in apparent enjoyment. In some of them, as Proteus and the amphibious Sirens, where the limbs are confined to the pectoral region, swimming seems to be the state most natural to them. They are truly amphibious, and they owe this double existence to the persistence of their gills; for in these perennibranchiate Batrachians, arteries are developed from the last pair of branchial arches which convey blood to the lungs: while, in those having external deciduous gills, the office being discharged, they lose their ciliate and vascular structure and disappear altogether. The skull in Reptiles generally consists of the same parts as in the Mammalia, though the proportions are different. The skull is flat, and the cerebral cavity, small as it is, is not filled with brain. The vertebral column commences at the posterior part of the head, two condyles occupying each side of the vertebral hole (Fig. 2). The anterior limbs are mostly shorter than the posterior, as might be expected of animals whose progression is effected by leaps. Ribs there are none. The sternum is highly developed, and a large portion of it is cartilaginous; it moves in its mesial portions the two clavicles and two coracoid bones, which fit on to the scapula, the whole making a sort of hand which supports the anterior extremities, and an elongated disk which supports the throat, and assists in deglutition and respiration. The bone of the arm (humerus) is single, and long in proportion to the fore arm. In the Frogs (Rana), the ilic bone is much elongated, and is articulated in a movable manner on the sacrum, so that the two heads of the thigh bones seem to be in contact. The femur, or thigh, is much lengthened and slightly curved, and the bones of the leg so soldered together as to form a single much elongated bone.
The respiration of Reptiles and some of the Batrachians, like that of Birds and Mammals, is aërial and pulmonary, but it is much less active. Batrachians have, in addition, a very considerable cutaneous respiration. Some of them, such as Toads, absorb more oxygen through the skin than by the lungs. Their circulation is 13 imperfect, the structure of the heart only presenting one ventricle; the blood, returning after a partial regeneration in the lungs, mingles with that which is not yet revivified: this mixed fluid is launched out into the economic system of the animal. Thus Reptiles and Batrachians are said to be cold-blooded animals, more especially the former, in which the respiratory organs, which are a constant source of interior heat, are only exercised very feebly. Owing to this low temperature of their bodies, reptiles affect warm climates, where the sun exercises its power with an intensity unknown in temperate regions; hence it is that they abound in the warm latitudes of Asia, Africa, and America, whilst comparatively few are found in Europe. This is also the cause of their becoming torpid during the winter of our latitudes: not having sufficient heat in themselves to produce reaction against the external cold, they fall asleep for many months, awakening only when the temperature permits of their activity. Serpents, Lizards, Tortoises, Frogs, are all subjected to this law of their being. Some hybernate upon the earth, under heaps of stones, or in holes; others in mud at the bottom of ponds. The senses are very slightly developed in these animals; those of touch, taste, and smell, are very imperfect; that of hearing, though less obtuse, leaves much to be desired; but sight in them is very suitably exercised by the large eyes, with contractile eye-balls, which enables certain reptiles—such, for instance, as the Geckos, to distinguish objects in the dark. Most Reptiles and Batrachians are almost devoid of voice: Serpents, 14 however, utter a sharp hissing noise, some species of Crocodiles howl energetically, the Geckos are particularly noisy, and Frogs have a well-known croak. In Reptiles and Batrachians the brain is small, a peculiarity which explains their slight intelligence and the almost entire impossibility of teaching them anything. They can, it is true, be tamed; but although they seem to know individuals, they do not seem to be susceptible of affection: the slight compass of their brain renders them very insensible, and this insensibility to pain enables them to support mutilations which would prove immediately fatal to most other animals. For instance, the Common Lizard frequently breaks its tail in its abrupt movements. Does this disturb him? Not at all! This curtailment of his being does not seem to affect him; he awaits patiently for the return of the organ, which complaisant nature renews as often as it becomes necessary. In the Crocodiles and Monitor Lizards, however, a mutilated part is not renewed, and the renovated tails of other Lizards do not develop bone. In some instances, the eyes may be put out with impunity, or part of the head may be cut off; these organs will be replaced or made whole in a certain time without the animal having ceased to perform any of the functions which are still permitted to him in his mutilated state. A Tortoise will continue to live and walk for six months after it is deprived of its brain, and a Salamander has been seen in a very satisfactory state although its head was, so to speak, isolated from the trunk by a ligature tied tightly close round the neck. There is another curious peculiarity in the history of Reptiles and Batrachians: each year as they awake from their state of torpor, they slough their old covering, and thus each year renew their youth; so far as the skin is concerned, it is certain that they retain their youth a very long time. Their growth is slow, and continues almost through the whole duration of their existence; they are, moreover, endowed with remarkable longevity. This is not very astonishing, if we consider that (at least in our latitudes) they remain torpid for several months yearly; thus using up less of the materials of life than most animals, they ought, consequently, to attain a more advanced age. The activity of organization in Reptiles and Batrachians is so slight that their stomachs feel less of the exigencies of hunger; hence they rarely take nourishment; they digest 15 their food with equal deliberation. With the exception of the Land Tortoises, whose regimen is herbivorous, most reptiles feed on living prey. Some, such as Lizards, Frogs, and Toads, prey on worms, insects, small terrestrial or aquatic Molluscs; others, such as Ophidians and Crocodiles, attack Birds, and even Mammalia. Large Serpents, owing to the distensibility of their œsophagus, swallow animals much larger than themselves. The Boa-constrictor darts upon the Deer, binds him in its snaky coils, breaks his bones, and little by little swallows him entirely.
Reptiles, whether Batrachians, Ophidians, or Chelonians, are mostly oviparous, sometimes ovo-viviparous, and some of them are very prolific. The eggs of some are covered with a calcareous envelope, as in the Turtle. Sometimes they are soft, and analogous to the spawn of fish, as in the Batrachians. They do not hatch their eggs by sitting upon them, but bury them in the sand, and take no further care of them, trusting to the heat of the sun, which hatches them in due course. To this the Pythons form a partial exception. Batrachians content themselves with diffusing their spawn or eggs in the marshy waters or ponds, or they bear them on their backs until the time of hatching approaches. On leaving the egg the young Tortoises have to provide immediately for their own wants, for the parents are not present to bring them their nourishment or to defend them against their enemies. This parental protection, so manifest among the superior animals, does not exist in oviparous species; that is, in those whose eggs are not hatched in the body of the mother. The young are, so to speak, produced in a living state, and fully prepared for the battle of life. The loves of these animals present none of that character of mutual affection and tender sympathy which distinguishes the Mammalia and Birds.5 When they have ensured the perpetuity of their species, they separate, and betake themselves again to their solitary existence.
Some reptiles attain dimensions truly extraordinary, which render them at times very formidable. Turtles are met with which weigh as much as sixteen hundred pounds, and the carapace 16 of one of these measured as much as six feet in length. The size of an ordinary Crocodile is from eight to nine feet, but they have been seen twenty-four and even thirty feet long, with a mouth opening from six to eight feet wide.
In Chelonians the surface of the skull is continuous without movable articulations. The head is oval in the Land Tortoises, the interval between the eyes large and convex, the opening of the nostrils large, the orbits round. The general distinguishing characteristic of Tortoises is the external position of the bones of the thorax, at once enveloping with a cuirass or buckler the muscular portion of the frame, and protecting the pelvis and shoulder bones. The ribs are inserted by means of sutures into these plates, and united with each other. A three-branched shoulder and cylindrical shoulder-blade are characteristic of the Tortoises. 17
In tropical regions enormous Serpents are found, which are as bulky as a man's thigh, and are said to be not less than forty feet in length. Roman annals mention one forty feet long, which Regulus encountered in Africa during the Punic wars, and which is fabulously said to have arrested the march of his army. These gigantic reptiles are not, however, the enemies which man has most cause to fear; their very size draws attention to them in such a manner that it is easy to avoid them. It is quite otherwise with Vipers twenty or thirty inches long; they glide after their prey without being seen, strike it cruelly with their fangs, leaving in the wound a venom which produces death with startling rapidity. Doubtless this fatal power was the origin of the worship which was rendered to certain reptiles by barbarous nations of old, and these animals are indeed still venerated by many savage races. The whole class of Reptiles are, for the most part, calculated to inspire feelings of disgust, and such has been the sentiment in all ages. Few people can suppress a movement of fright at the sight of an ordinary Snake, Lizard, or Frog, notwithstanding that they are most inoffensive animals. Several causes concur to this aversion. In the first place the low temperature of their bodies, contact with which communicates an involuntary shudder in the person who tries to touch one of them; then the moisture which exudes from the skins of Frogs, Toads, and Salamanders; their fixed and strong gaze, again, impresses one painfully in thinking of them; the odour which some of them exhale is so disgusting, that it alone sometimes causes fainting; add to this the fear of a real or often exaggerated danger, and we shall have the secret of the sort of instinctive horror which is felt by many people at the sight of most reptiles. Nevertheless, the injurious species are exceptional amongst reptiles, and there are not any amongst the Batrachians, for it is altogether a mistake to take for venom the fluid which the toad discharges.6 It is true that these animals are repulsive in appearance, we can nevertheless recognise their services in the economy of nature. Inhabitants of slimy mud and 18 impure swamps, they make incessant war upon the worms and insects which abound in those localities. In their turn they find implacable enemies in the birds of the marshes, which check their prodigious multiplication. In this manner equilibrium is maintained.
Some of the animals which now occupy our attention render more direct service to man by the part which they fulfil at his table. Frogs are eaten in the south of France, Italy, and many other countries; and in some parts of the south of France, Adders are eaten under the name of Hedge-eels. We know the favour in which Turtles are held in England, where turtle-soup is considered a dish only fit for merchant princes. In some countries Iguanas, Crocodiles, and even Serpents are eaten. Viper-broth, which was known to Hippocrates, is discontinued as an article of food.
As we have already remarked, the peculiar nature of their organization leads Reptiles and Batrachians to seek the warmer regions of the earth. It is in those regions that they attain the enormous dimensions which distinguish certain Serpents; there, too, they secrete their most subtle poisons, and display the most lively colours—which, if less rich than those of Birds and Fishes, are not less startling in effect. Many Serpents and Lizards glitter with radiant metallic reflections, and some of them present extremely varied combinations of colour. Chameleons are found in the same localities, but in the Old World only; these and some other Lizards are remarkable for changing their colour, a phenomenon which is also seen among the Frogs, but in a smaller degree.
Reptiles and Batrachians were numerous in the early ages of our globe. It was then that those monstrous Saurians lived, whose dimensions even are startling to our imagination. The forms of the Reptiles and Batrachians of the early ages of the earth were much more numerous, their dimensions much greater, and their means of existence more varied than those of the present time. Our existent Reptiles are very degenerate descendants of those of the great geological periods, unless we except the Crocodiles and the gigantic Boas and Pythons. Whilst the Reptiles of former ages disported their gigantic masses, and spread terror amongst other living creatures, alike by their formidable armature and their prodigious numbers, they are now 19 reduced to a much lower number of species. There are now but little more than 1,500 species of Reptiles and Batrachians described, and only 100 of those belong to Europe.7
Animals which compose this class have long been confounded with reptiles, from which they differ in one fundamental peculiarity in their organization. At their birth they respire by means of gills, and consequently resemble fishes. In a physiological point of view, at a certain time in their lives, these animals are fishes in form as well as in their habits and organization. As age progresses, they undergo permanent metamorphosis—they acquire lungs, and thenceforth an aërial respiration. It is, then, easy to understand that these animals hold a doubtful rank, as they have long done, amongst Reptiles, which are animals with an aërial respiration; they ought to form a separate class of Vertebrates.8
Batrachians establish a transitional link between Fishes and Reptiles—they are, as it were, a bond of union between those two groups of animals. In the adult state Batrachians are cold-blooded animals with incomplete circulation, inactive respiration, and the skin is bare. In the introductory section to this chapter we have given the general characteristics which belong to them. The Frogs—Tree Frogs, Toads, Surinam Toads, Salamanders, and Newts—are the representatives of the principal families of Batrachians of which we propose giving the history.
The Frogs, Rana, have been irreparably injured by their resemblance to the Toads. This circumstance has given rise to an unfavourable prejudice against these innocent little Batrachians. Had the Toad not existed, the Frog would appear to us as an animal of a curious form, and would interest us by the phenomena of transformation which it undergoes in the different epochs of its development. We should see in it a useful inoffensive animal of slender form, with delicate and supple limbs, arrayed in that 20 green colour which is so pleasant to the eye, and which mingles so harmoniously with the carpeting of our fields.
The body of the Edible Frog, Rana esculenta (Fig. 4), sometimes attains from six to eight inches in length, from the extremity of the muzzle to the end of the hind feet. The muzzle terminates in a point; the eyes are large, brilliant, and surrounded with a circle of gold colour. The mouth is large; the body, which is contracted behind, presents a tubercular and rugged back. It is of a more or less decided green colour on the upper, and whitish on the under parts. These two colours, which harmonize well, are relieved by three yellow lines, which extend the whole length of the back, and by scattered black marbling. It is, therefore, much to be regretted that prejudice should cause some at least of us to turn away from this pretty little hopping animal, when met with in the country; with its slight dimensions, quick movements, and graceful attitudes. For 21 ourselves, we cannot see the banks of our streams embellished by the colours and animated with the gambols of these little animals without pleasure. Why should we not follow with our eyes their movements in our ponds, where they enliven the solitude without disturbing its tranquillity. Frogs often leave the water, not only to seek their nourishment, but to warm themselves in the sun. When they repose thus, with the head lifted up, the body raised in front and supported upon the hind feet, the attitude is more that of an animal of higher organization than that of a mean and humble Batrachian. Frogs feed on larvæ, aquatic insects, worms, and small mollusks. They choose their prey from living and moving creatures; for they set a watch, and when they perceive it, they spring on it with great vivacity. A large Indian species (R. tigrina) has been seen to prey occasionally upon young Sparrows. Far from being dumb, like many oviparous quadrupeds, Frogs have the gift of voice. The females only make a peculiar low growl, produced by the air which vibrates in the interior of two vocal pouches placed on the sides of the neck; but the cry of the male is sonorous, and heard at a great distance: it is a croak which the Greek poet, Aristophanes, endeavoured to imitate by the inharmonic consonants, brekekurkoax, coax! It is principally during rain, or in the evenings and mornings of hot days, that Frogs utter their confused sounds. Their chanting in monotonous chorus makes this sad melody very tiresome. Under the feudal system, during the "good old times" of the middle ages, which some people would like to bring back again, the country seats of many of the nobility and country squires were surrounded by ditches half full of water, all inhabited by a population of croaking Frogs. Vassals and villains were ordered to beat the water in these ditches morning and evening in order to keep off the Frogs which troubled the sleep of the lords and masters of the houses. Independent of the resounding and prolonged cries of which we have spoken, at certain times the male Frog calls the female in a dull voice, so plaintive that the Romans described it by the words "ololo," or "ololygo." "Truly," says Lacépède, "the accent of love is always mingled with some sweetness."
When autumn arrives Frogs cease from their habitual voracity, 22 and no longer eat. To protect themselves from the cold, they bury themselves deeply in the mud: troops of them joining together in the same place. Thus hidden, they pass the winter in a state of torpor; sometimes the cold freezes their bodies without killing them. This state of torpor gives way in the first days of spring. During the month of March, Frogs begin to awake and to move themselves; this is their breeding season. Their race is so prolific that a female can produce from six to twelve hundred eggs annually. These eggs are globular, and are in form a glutinous and transparent spheroid, at the centre of which is a little blackish globule; the eggs float, and form like chaplets on the surface of the water.

All who have observed the small ponds and ditches in the country at this season, will have seen these light and elegant 23 crafts swimming on the surface of the water. After a few days, more or less according to the temperature, the little black spot which is the embryo of the egg, and which has developed itself in the interior of the glairy mass which envelops it, disengages itself and shoots forth into the water: this is the tadpole of the Frog.
The body of the tadpole is oval in shape, and terminates in a long flat tail, which forms a true fin; on each side of the neck are two large gills, in shape like a plume of feathers; the tadpole has no legs. These gills soon begin to wither, without aquatic respiration ceasing, however; for, besides these, the tadpole possesses interior gills like fishes. Soon after, the legs begin to show themselves, the hind legs appearing first; they acquire a considerable length before the fore feet begin to show themselves. These develop themselves under the skin, which they presently pierce through. When the legs have appeared, the tail begins to fade, and, little by little, withers away, until in the perfect animal it entirely disappears. About the same time the lungs become developed, and assume their functions. In Fig. 5 may be traced the successive phases of its transformation from the egg to the tadpole, till we finally reach the perfect Batrachian. Through these admirable modifications we see the Fish, little by little, become a Batrachian. In order to follow this strange metamorphosis, it suffices to gather some Frog's eggs, and to place them with some aquatic herbs in an aquarium, or in a globe with Gold and Silver Fish; it there constitutes a most interesting spectacle, and we advise our readers to give themselves this instructive and easy lesson in natural history.
At present, there exist two species of Frog in Europe: the Green or Edible Frog, and the Common Frog. The Green Frog is that which we have described, and of which we have given a representation in Fig. 4. They are found in running streams and stagnant waters. It is this species to which La Fontaine alludes in one of his fables. Common Frogs are smaller than the preceding: they inhabit damp places in fields and vineyards, and only return to the water to breed or to winter.
The flesh of the Edible Frog is very tender, white, and delicate. As an article of food, it is lightly esteemed by some, but undeservedly 24 so. Prepared in the same manner, Green Frogs closely resemble very young fowls in taste. In almost all parts of France Frogs are disdained as articles of food; it is only in the south that a taste for them is openly avowed, and there Frogs are sought for and brought to market. Therefore, I never could comprehend how the notion popular in England, when it is wished to express contempt for Frenchmen, should be to call them Frog-eaters. It is a reproach which might be addressed to Provençals and Languedocians like the author of this work, but not at all to the majority of Frenchmen.
The Green Tree Frog is easily distinguished by having little plates under its toes. These organs are a species of sucker, by means of which the animal is enabled, like the house-fly, to cling strongly to any surface, however smooth and polished it may be. The smoothest branch, even the lower surface of a leaf, forms a sufficient hold and support to these delicate organs.
The upper part of the body is of a beautiful green, the lower part, where little tuberculi are visible, is white. A yellow line, lightly bordered with violet, extends on each side of the head and back, from the muzzle to the hind legs. A similar line runs from the jaw to the front legs. The head is short, the mouth round, and the eyes raised. Much smaller than the ordinary Frog, 25 they are far more graceful. During the summer they live upon the leaves of trees in damp woods, and pass the winter at the bottom of some pond, which they do not leave till the month of May, after having deposited their eggs. They feed on small insects, worms, and mollusks; and in order to catch them, they will remain in the same place an entire day. During the glare of the sun, they remain hidden amongst the leaves; but when twilight approaches, they move about and climb up the trees. We must repeat of these Green Tree Frogs what we have already said of Frogs. Get rid of all prejudice towards their kind, and then you will examine with pleasure their lively colours, which harmonize so well with the green leaves; remark their tricks and ambuscades; follow them in their little hunting excursions; see them suspended upside down upon the leaves in a manner which appears marvellous to those who are not aware of the organs which have been given to enable them to attach themselves to the smoothest bodies: and it will give as much pleasure as can be derived from the consideration of the plumage, habits, and flight of birds. The croak of the Green Tree Frogs is like that of other Frogs, although less sharp and sometimes stronger in the males; it can be pretty well translated by the syllables caraccarac, pronounced from the throat. This cry is principally heard in the morning and evening; then, when one Frog begins to utter its croak, all the others imitate it. In the quiet night the voice of a troop of these little Batrachians sometimes reaches to an enormous distance.
Toads, Bufo, are squat and disagreeable in shape: it is difficult to comprehend why nature, which has bestowed elegance and a kind of grace upon Frogs and Tree Frogs, has stamped the Toad with so repulsive a form. These much despised beings occupy a large place in the order of nature: they are distributed with profusion, but one cannot say exactly to what end; their movements are heavy and sluggish. In colour they are usually of a livid grey, spotted with brown and yellow, and disfigured by a number of pustules or warts. A thick and hard skin covers a flat back; its large belly always appears to be swollen; the head a little broader than the rest of its body; the mouth and the eyes are large and prominent. It lives chiefly at the bottom of ditches, especially those 26 where stagnant and corrupt water has lain a long time. It is found in dung heaps, caves, and in dark and damp parts of woods. One has often been disagreeably surprised on raising some great stone to discover a Toad cowering against the earth, frightful to see, but timorous, seeking to avoid the notice of strangers. It is in these different obscure and sometimes fœtid places of refuge that the Toad shuts itself up during the day; going out in the evening, when our common species moves by slight hops; whilst another, the Natterjack Toad, Bufo calamita, only crawls, though somewhat fastly. When seized, it voids into the hand a quantity of limpid water imbibed through the pores of its skin; but if more irritated, a milky and venemous humour issues from the glands of its back.
One peculiarity of its structure offers a defence from outward attacks. Its very extensible skin adheres feebly to the muscles, and at the will of the animal a large quantity of air enters between this integument and the flesh, which distends the body, and fills the vacant space with an elastic bed of gas, by means of which it is less sensible to blows. Toads feed upon insects, worms, and small mollusks. In fine evenings, at certain seasons especially, they may be heard uttering a plaintive monotonous sound. They assemble in ponds, or even in simple puddles of water, where they 27 breed and deposit their eggs. When hatched, the young Toads go through the same metamorphosis as do the tadpoles of the Frogs.
Their simple lives, though very inactive, are nevertheless very enduring; they respire little, are susceptible of hibernation, and can remain for a considerable time shut up in a very confined place.
It is proper, however, to caution the reader against believing all that has been written about the longevity of Toads. Neither must implicit faith be given to the discovery of the living animal (Fig. 7) in the centre of stones. "That Toads, Frogs, and Newts, occasionally issue from stones broken in a quarry or in sinking wells, and even from coal-strata at the bottom of a mine," is true enough; but, as Dr. Buckland observes, "the evidence is never perfect to show that these Amphibians were entirely enclosed in a solid rock; no examination is made until the creature is discovered by the breaking of the mass in which it was contained, and then it is too late to ascertain whether there was any hole or crevice by which it might have entered." These considerations led Dr. Buckland to undertake certain experiments to test the fact. He caused blocks of coarse oölitic limestone and sandstone to be prepared with cells of various sizes, in which he enclosed Toads of different ages. The small Toads enclosed in the sandstone were found to die at the end of thirteen months; the same fate befell the larger ones during the second year: they were watched through the glass covers of their cells, and were never seen in a state of torpor, but at each successive examination they had become more meagre, until at last they were found dead. This was probably too severe a test for the poor creatures, the glass cover implying a degree of hardness and dryness not natural to half amphibious Toads. Moreover, it is certain that both Toads and Frogs possess a singular facility for concealing themselves in the smallest crevices of the earth, or in the smallest anfractuosities of stones placed in dark places.
This animal, so repulsive in form, has been furnished by nature with a most efficient defensive armature; namely, an acrid secretion which will be described farther on. It is a bad leaper, an obscure and solitary creature, which shuns the sight of man, as if it comprehended the blot it is on the fair face of creation. It is, nevertheless, susceptible of education, and 28 has occasionally been tamed; but these occasions have been rare. Pennant, the zoologist, relates some curious details respecting a poor Toad, which took refuge under the staircase of a house. It was accustomed to come every evening into a dining-room near to the place of its retreat. When it saw the light it allowed itself to be placed on a table, where they gave it worms, wood-lice, and various insects. As no attempt was made to injure it, there were no signs of irritation when it was touched, and it soon became, from its gentleness (the gentleness of a Toad!), the object of general curiosity; even ladies stopped to see this strange animal. The poor Batrachian lived thus for six and thirty years; and it would probably have lived much longer had not a Crow, tamed, and, like it, a guest in the house, attacked him at the entrance of his hole, and put out one of his eyes. From that time he languished, and died at the end of a year.
Nearly allied to the Toads, Bufo, the Surinam Toad, Pipa, holds its place. Its physiognomy is at once hideous and peculiarly 29 odd: the head is flat and triangular, a very short neck separates it from the trunk, which is itself depressed and flattened. Its eyes are extremely small, of an olive, more or less bright, dashed with small reddish spots. It has no tongue. There is only one species of Pipa, viz. the American Pipa (Fig. 8), which inhabits Guiana and several provinces of Brazil. The most remarkable feature in this Batrachian is its manner of reproduction. It is oviparous, and when the female has laid her eggs, the male takes them, and piles upon the back of his companion these, his hopes of posterity. The female, bearing the fertilized eggs upon her back, reaches the marshes, and there immerses herself; but the skin of the back which supports the eggs soon becomes inflamed, erysipelatous inflammation follows, causing an irritation, produced by the presence of eggs, which are then absorbed into the skin, and disappear in the integument until hatched.
The young Pipa Toads are rapidly developed in these dorsal cells, but they are extricated at a less advanced stage than almost any other vertebrate animal. After extrication, the tadpole grows rapidly, and the chief change of form is witnessed in the gills. As to the mother Batrachian, it is only after she has got rid of her progeny that she abandons her aquatic residence.9
The Batrachians differ essentially from all other orders of Reptilia. They have no ribs; their skin is naked, being without scales. The young, or tadpoles, when first hatched, breathe by means of gills, being at this stage quite unlike their parents. These gills, or branchiæ, disappear in the tailless Batrachians, as the Frogs and Toads, in which the tail disappears, are called. In the tadpoles the mouth is destitute of a tongue, this organ only making its appearance when the fore limbs are evolved. The habits also change. The tadpole no longer feeds on decomposing substances, and cannot live long immersed in water. The branchiæ disappear one after the other, by absorption, giving place to pulmonary vessels. The principal vascular arches are converted into the pulmonary artery, and the blood is diverted from the largest of the branchiæ to the lungs. 30 In the meantime the respiratory cavity is formed, the communicating duct advances with the elongation of the œsophagus, and at the point of communication the larynx is ultimately developed. The lungs themselves extend as simple elongated sacs, slightly reticulated on the inner surface backwards into the abdominal cavity. These receptacles being formed, air passes into and expands the cavity, and respiration is commenced, the fore limbs are liberated from the branchial chambers, and the first transformation is accomplished.
The alleged venemous character of the Common Toad has been altogether rejected by many naturalists; but Dr. Davy found that venemous matter was really contained in follicles in the true skin, and chiefly about the head and shoulders, but also distributed generally over the body, and on the extremities in considerable quantities. Dr. Davy found it extremely acrid, but innocuous when introduced into the circulation. A chicken inoculated with it was unaffected, and Dr. Davy conjectures that this acrid liquid is the animal's defence against carnivorous Mammalia. A dog when urged to attack one will drop it from its mouth in a manner which leaves no doubt that it had felt the effects of the secretion.
In opposition to these opinions the story of a lad in France is told, who had thrust his slightly wounded hand into a hole, intending to seize a Lizard which he had seen enter. In place of the Lizard he brought out a large Toad. While holding the animal, it discharged a milky yellowish white fluid which introduced itself into the wound in his hand, and this poison occasioned his death; but then it is not stated that the boy was previously healthy.
Warm and temperate regions with abundant moisture are the localities favourable to all the Batrachians. Extreme cold, as well as dry heat, and all sudden changes are alike unfavourable to them. In temperate climates, where the winters are severe, they bury themselves under the earth, or in the mud at the bottom of pools and ponds, and there pass the season without air or food, till returning spring calls them forth.
The species of this family are very numerous. MM. Duméril and Bibron state that the Frogs, Rana, number fifty-one species; the Tree Frogs, Hyla, sixty-four; and the Toads, Bufo, thirty-five. 31 They are found in all parts of the world, the smallest portion being found in Europe, and the largest in America. Oceania is chiefly supplied with the Tree Frogs. There are several curious forms in Australia, and one species only is known to inhabit New Zealand. The enormous fossil Labyrinthodon, of a remote geological era, is believed to have been nearly related to these comparatively very diminutive Batrachians.10
Sometimes called Urodeles, from ουρα, "tail," δηλος, "manifest." The constant external character which distinguishes these Amphibians in a general manner is the presence of a tail during the whole stage of their existence. Nevertheless they are subject to the metamorphoses to which all the Amphibians submit. "The division, therefore, of reptiles," says Professor Rymer Jones, "into such as undergo metamorphoses and such as do not, is by no means philosophical although convenient to the zoologist, for all reptiles undergo a metamorphosis although not to the same extent. In the one the change from the aquatic to the air-breathing animal is never fully accomplished; in the tailed Amphibian the change is accomplished after the embryo has escaped from the ovum."
Salamanders have had the honour of appearing prominently in fabulous narrative. The Greeks believed that they could live in fire, and this error obtained credence so long, that even now it has not been entirely dissipated. Many people are simple enough to believe from the Greek tradition that these innocent animals are incombustible. The love of the marvellous, fostered and excited by ignorant appeals to superstition, has gone even further than this; it has been asserted that the most violent fire becomes extinguished when a Salamander is thrown into it. In the middle ages this notion was held by most people, and it would have been dangerous to gainsay it. Salamanders were necessary animals in the conjurations of sorcerers and witches; accordingly painters among their symbolical emblems represented Salamanders as capable of 32 resisting the most violent action of live coal. It was found necessary, however, that physicians and philosophers should take the trouble to prove by experiment the absurdity of these tales.
The skull of the Land or Spotted Salamander, Salamandra maculosa, is well described by Cuvier as being nearly cylindrical, wider in front so as to form the semi-circular face, and also behind for the crucial branches, containing the internal ears. The cranium of the aquatic Salamander differs from the terrestrial in having the entire head more oblong, and they differ also among themselves.
In the Land Salamander the body is black and warty with large irregular yellow spots distributed over the head, back, sides, feet, and tail. They affect obscure and moist places, and only issue from their retreat in the night or morning, walking slowly, and dragging themselves with difficulty along the surface of the ground. They live upon flies, beetles, snails, and earth worms. They remain in the water to deposit their eggs; the young are born alive, and furnished with fully-developed gills. Moreover Salamanders are gifted with a power which causes them to be much dreaded by other animals: it has the power of discharging an acrid and milky humour, with a very strong odour, from the surface of its body, which serves as a defence against many animals which would otherwise attack it. It has been proved by experiment that this liquid, when introduced 33 into the circulatory system by a small wound is a very active poison, and causes certain death to the smaller animals. This species is found in most parts of Europe, but not in the British Islands.
The Black Salamander, Triton alpestris, has no spots; it is found on the highest European mountains, in the regions of snow, and principally on the highest Alps.
Newts, or Aquatic Salamanders, have not a round conical tail like the terrestrial species, but have that appendage compressed or flattened laterally. The males (during the breeding season only) are recognised chiefly by the membranous serrated ridge or crest which extends along the whole length of the back, from the head to the extremity of the tail, as represented in Fig. 10. Newts are highly aquatic; they are found in ditches, marshes, and ponds, which after the breeding season they leave for moist places on land, often then finding their way into drains and cellars. They are carnivorous, feeding upon different insects and on the spawn of Frogs, not even sparing individuals of their own species. The females deposit their eggs singly, fixing them on the under surface of the leaves of aquatic plants. "Some Newts," says Professor Owen, "deposit their eggs upon aquatic plants, such as Polygonum persicaria, folding the leaf by means of the hind feet 34 in such a way that its under surface is turned inwards and the fold made to stick by the adhesive coating of the egg, which she inserts in the fold." The young are hatched fifteen days after. These animals give utterance to a very peculiar noise, and when touched emit an odour quite characteristic.
It has been ascertained that Newts can live for a long time, not only in very cold water, but even in the midst of ice, being sometimes taken in blocks of ice which are formed in the ditches and ponds which they inhabit. When the ice-flakes melt they seem to awaken from their torpor, and betake themselves to their accustomed movements with their recovered liberty. Lacépède states that he found Aquatic Salamanders even during summer in pieces of ice obtained from the ice-dealers, where they had remained without movement or nourishment from the time when the ice had been gathered from the marshes.
Newts present another remarkable feature in the facility with which they repair any mutilations they may have undergone. Not only do their tails grow again when broken off, but even their feet are reproduced in the same manner, and the process may be many times repeated.
The Crested Newt, Triton cristatus, is frequently found in the neighbourhood of Paris; the skin of its back is rough and warty, of a brownish colour, with large black spots and white projecting points; the belly has black spots upon an orange ground.
The Dutch traveller, Sieboldt, has introduced a species of Aquatic Salamander, which inhabits the mountain lakes and marshes of Japan. This species is remarkable for its gigantic growth. Instead of being the size of a finger, as is the case with those indigenous to Europe, this Batrachian is four feet and a half in length, and weighs fifty pounds.
Magnificent specimens of this gigantic Salamander, the Sieboldtia maxima, may be seen by the visitors to the London Zoological Gardens. The largest of them measured and weighed as above (March 3rd, 1869). An analogous large fossil species was described as the Homo diluvii testis!
The transformation of the tailed Batrachians, from the tadpole condition to the air-breathing and four-footed state, is one of the most interesting exhibitions of Nature, and one which everyone 35 may verify for himself. We cannot in our brief description have a more trustworthy guide than Professor Rymer Jones, who selects the Water Newt, Triton cristatus, as an example:—
"Immediately before leaving the egg," he says, "this tadpole presents both the outward form and internal structure of a fish. The flattened and vertical tail, fringed with a broad dorsal and oval fin; the shape of the body and gills, appended to the side of the neck, are all apparent; so that were the creature to preserve this form throughout its life the naturalist would scarcely hesitate in classing it with fishes, properly so called.
"When first hatched it presents the same fish-like body, and rows itself through the water by the lateral movement of the caudal fin. The only appearance of legs as yet visible consists in two minute tubercles, which seem to be sprouting out from the skin immediately behind the branchial tufts, and which are, in fact, the first buddings of anterior extremities. Nevertheless, to compensate to a certain extent for the total want of prehensile limbs, which afterwards become developed, two supernumerary organs are provisionally furnished in the shape of two minute claspers on each side of the mouth; by means of these the little creature holds on to the leaves which are under water.
"Twelve days after issuing from the egg, the two fore-legs, which at first resembled two little nipples, have become much elongated, and are divided at their extremity into two or three rudiments of fingers. The eyes, which were before scarcely visible, being covered by a membrane, distinctly appear. The branchiæ, at first simple, are divided into fringes, wherein red blood now circulates; the mouth has grown very large, and the whole body is so transparent as to reveal the position of the viscera within. Its activity is likewise much increased; it swims with rapidity, and darts upon minute aquatic insects, which it seizes and devours.
"About the twenty-second day the tadpole for the first time begins to emit air from the mouth, showing that the lungs have begun to be developed. The branchiæ are still large. The fingers upon the fore-legs are completely formed. The hind-legs begin to sprout beneath the skin, and the creature presents, in a transitory condition, the same external form as that which the Siren lacertina permanently exhibits. 36
"By the thirty-sixth day the young Salamander has arrived at the development of the Proteus anguinus; its hind-legs are nearly completed; its lungs have become half as long as the trunk of the body, and its branchiæ more complicated in structure.
"At about the forty-second day the tadpole begins to assume the form of an adult Newt. The body becomes shorter, the fringes of the branchiæ are rapidly obliterated, so that in five days they are reduced to simple prominences covered by the skin of the head; and the gills opening at the sides of the neck, which allowed the water to escape from the mouth as in fishes, and were, like them, covered with an operculum formed by a fold of the integument, are gradually closed; the membranous fin of the tail contracts, the skin becomes thicker and more deeply coloured, and the creature ultimately assumes the form and habits of the perfect Newt, no longer possessing branchiæ, but breathing air, and in every particular the Reptile."
But however curious the phenomena attending the development of the tadpoles of the Amphibian Reptiles may be to the observer who merely watches the changes perceptible from day to day in their external form, they acquire tenfold interest to the physiologist who traces the progressive evolution of their internal viscera; more especially when he finds that in these creatures he has an opportunity afforded him of contemplating, displayed before his eyes, as it were, upon an enlarged scale, those phases of development through which the embryo of every air-breathing vertebrate animal must pass while concealed within the egg, or yet unborn.11

Reptiles are, as has been said in the preceding chapter, Vertebrated Animals, breathing by lungs, having red and cold blood; that is to say, not producing sufficient heat to render their temperature superior to that of the atmosphere. Destitute of hairs, of feathers, of mammary glands, and having bodies covered with scales.
Snakes, properly so called, have the tympanic bone, or pedicle of the lower jaw, movable, and nearly always suspended to another bone, analogous to the mastoid bone, which is attached to the cranium by muscles and ligaments, a conformation which gives to these animals the vast power of distension they possess. Their trachea is long, their hearts placed far back, and the greater number have one very long lung and vestiges of a second. They are divided into non-venemous and venemous; and the latter are subdivided into venemous with maxillary teeth, and venemous with isolated fangs.
The Snakes prey almost exclusively on animals of their own killing; the more typical species attacking such as are frequently larger than themselves: and the maxillary apparatus is, as we have seen, modified so as to permit of the requisite distension. According to Professor Owen's clear and intelligible description, the two superior maxillary bones have their anterior extremities joined by an elastic and yielding fibrous tissue with the small and single intermaxillary bone; the lower maxillary rami are similarly connected. The opposite extremity of each ramus is articulated to a long and movable vertical pedicle formed by the tympanic bone, which is itself attached to the 39 extremity of a horizontal pedicle formed by the mastoid bone, so connected as to allow of a certain yielding movement upon the cranium. The other bones have similar loose movable articulations, which concur in yielding to the pressure of large bodies with which the teeth have grappled.
The class of Reptiles is divided into three orders:—the Ophidians, comprehending the Snakes; the Saurians, the Lizards and Crocodiles; and the Chelonians, the Turtles and Tortoises.
In Ophidians, commonly known under the name of Snakes, the body is long, round, and straight. They have neither feet, fins, nor other locomotive extremities. Their mouths are furnished with pointed hooked teeth. In the Boas and Pythons the teeth are slender, curved, bending backwards and inwards above their base of attachment. In others each maxillary bone has a row of larger ones, which gradually decrease in size as they are placed further back. These teeth are not contiguous, being separated by considerable intervals. The smaller non-venemous Serpents, such as the Colubridæ, have two rows of teeth in the roof of the mouth. Each maxillary and mandibular bone includes from twenty to twenty-five teeth. In the Rattlesnakes and some other typical genera of poisonous Snakes, the short maxillary bone only supports a single perforated fang. Their lower jaw is highly distensible; the opening beings longer than the skull. They have no neck; their eyelids are immovable; their skin is coriaceous, highly extensible, and scaly or granulous, covered with a thin caducous epidermis, which detaches itself in one entire piece, and is reproduced several times in one year. Their movements are supple and varied. In consequence of the sinuosity of their bodies,—for, though scale-clad, Snakes are without apparent means of progression,—they make their way with the utmost facility, by walking, leaping, climbing, or swimming.
According to the genus chiefly, the very numerous species inhabit either arid or moist places, the ground, or bushes and trees. Some pass much of their time in the water, and one family (that of the Hydrophidæ) is exclusively aquatic—even 40 pelagic in the instance of one very widely diffused species, the Pelamis bicolor. In the Arboreal Snakes the tail is very long, and highly prehensile; in others, as the Vipers, it is short and without any prehensility. In the Sea Snakes (Hydrophidæ), it is laterally much compressed. Like other true reptiles, Snakes abound more especially in warm climates, and there are many kinds of them in Australia; but the order has not a single representative in New Zealand.
Most of the Snakes feed on living animals, only a few on birds' eggs. Several kinds of them prey habitually on other Snakes, as the genera Hamadryas, Bungarus, and Elaps, even Psammophis occasionally; and there are rare instances of non-venemous Snakes preying upon poisonous ones. The venemous kinds first kill their victim by poisoning it; various others by smothering it between the coils of their body. As they do not possess organs for tearing the prey to pieces, nor a dentition fit for mastication, the prey is swallowed entire; and in consequence of the great width of the mouth, and of the extraordinary extensibility of the skin of the gullet, they are able to swallow animals of which the girth much exceeds their own. The Sea Snakes prey mostly upon fishes, and the ordinary Water Snakes (Homolopsidæ, &c.) on frogs and other Batrachians. Certain swallowers of birds' eggs have peculiar spinous processes proceeding from the vertebræ of the neck, the object of which is to fracture the shell of an egg during the process of deglutition.
Most of the Ophidian Reptiles are oviparous, but many are ovo-viviparous. The Pythons alone (so far as ascertained) perform a sort of incubation, which has been repeatedly observed of captive specimens of these huge Serpents.
Many Snakes are remarkable for their great beauty of colouring, or of the pattern of their markings; but on account of the poisonous property of so many of them, the whole order is popularly regarded with horror and apprehension, and the most foolish tales are current respecting various species of them. Thus many people suppose that there are Snakes which rob cows of their milk; and the skeleton of a child being found in the same hollow with a number of harmless Snakes (the North American Coryphodon constrictor), it was concluded, as a matter of course, 41 that the Serpents must have both killed the child and stripped off its flesh, which latter is what no Snake could possibly do. People are prone to exaggerate, and commonly evince a fondness for the marvellous, which induce those of hot countries more especially, where the species of Ophidians are numerous, to declare every Snake met with as usually the most venemous one in their country; and thus travellers often come away with exceedingly erroneous impressions on the subject. The Indian region surpasses every other part of the globe in the number and variety of its Ophidians, and almost every investigation of a limited but previously unexplored district, is tolerably sure to add largely to our previous knowledge of them. What, however, the late Sir J. Emerson Tennent asserts of those inhabiting Ceylon, is equally applicable to other parts of the Indian region. "During my residence in Ceylon," he remarks, "I never heard of the death of an European which was caused by the bite of a Snake; and in the returns of coroners' inquests made officially to my department, such accidents to the natives appear chiefly to have happened at night, when the reptiles, having been surprised or trodden on, inflicted the wound in self-defence. For these reasons the Cingalese, when obliged to leave their houses in the dark, carry a stick with a loose ring, the noise of which, as they strike it on the ground, is sufficient to warn the Snakes to leave their path."
In some parts of the vast Indian region the natives regard the innocuous Chameleon as venemous; in other parts various Geckos, or other Lizards. In Bengal there is a current notion regarding a terrifically poisonous Lizard, which is termed the Bis-cobra, but which has no existence except in the imagination of the natives—who bring the young of the Monitors and occasionally other well-known Lizards as exemplifying the object of their dread. Again, the little harmless Burrowing Snakes (Typhlops), which, superficially, have much the appearance of earth-worms, are there popularly regarded as highly poisonous, though not only are they harmless, but physically incapable of wounding the human skin. Strangers who are little versed in zoology are commonly led astray by such errors on the part of natives of those countries, and, unfortunately, there is a number of stock vernacular names which are applied to very different species in different localities. Thus Europeans 42 in India are familiar with the appellation "Carpet Snake," as denoting a very deadly reptile, but nobody can there point out what the Carpet Snake really is; and the one most generally supposed to bear that name is a small innocuous Snake (Lycodon aulicus), which is common about human dwellings. In the Australian colony of Victoria, however, the appellation Carpet Snake is bestowed upon a terribly venemous species (Hoplocephalus curtus); while in the neighbouring colony of New South Wales, a harmless and even useful creature (Morelia spilotes) is habitually known as the Carpet Snake.
With regard to the poison of Venemous Snakes, attention has lately been directed to the virtue of ammonia or volatile alkali. This should be administered internally, mixed with alcoholic spirit and water, in repeated doses; and it should also be injected into a vein—about one drachm of the liquor ammoniæ of the shops being mixed with two or three times that quantity of water. The patient should be kept moving as much as possible, and the effects of a galvanic battery should also be tried in cases where animation is nearly or quite suspended. By these means it is asserted that quite recently, in Australia, some very remarkable cures have been effected.
The Ophidia have many enemies, as the well-known Mongoose among mammalia, also Swine, and various ruminating quadrupeds, as Deer and Goats. In the bird class, the famous Serpent-eater, or Secretary-bird of South Africa, is one of their chief destroyers; and there are various other Snake-devouring birds of prey, besides the great African Ground Hornbill,—even the Pea-fowl and sundry Storks and other waders. Comparatively large birds of the King-fisher family prey chiefly upon Snakes and Lizards in Australia; and of reptiles, besides those Snakes which prey upon other Snakes, the Monitor Lizards frequently seize and devour them.
The series of Ophidians is arranged by our most eminent herpetologist, Dr. A. Günther, into five subordinate groups, which he characterises as follows:—
I. Burrowing Snakes, living under ground, only occasionally appearing above the surface. They are distinguished by a rigid cylindrical body, short tail, narrow mouth, small head not distinct from the neck, little teeth in small number, and by the 43 absence or feeble development of the ventral shields. They feed chiefly on small invertebrate animals. Not any of them are venemous.
II. Ground Snakes, or species which live above ground, and only occasionally climb bushes or enter the water; their body is more or less cylindrical, very flexible in every part, and of moderate proportions. Their ventral shields are broad. They feed chiefly on terrestrial vertebrate animals. By far the greater number of Snakes belong to this category, and it is represented by many variations in all of the three sub-orders to be noticed presently.
III. Tree Snakes, or species passing the greater part of their life on bushes and trees, which they traverse with the utmost facility. They are distinguished either by an exceedingly slender body, with broad, sometimes carinated, ventral shields, or by a prehensile tail. Many of the species are characterised by their vivid coloration, of which green forms the principal part. We shall see, in the sequel, that the first and third sub-orders offer numerous instances of Tree Snakes; the Tree Snakes of the second sub-order being confined to Tropical Africa. They feed on animals which have a mode of life similar to their own; only a few species on eggs.
IV. Fresh-water Snakes, distinguished by the position of the nostrils, which are placed on the top of the snout, and by a tapering tail. They inhabit fresh-waters, and are, therefore, excellent swimmers and divers; only a few species (which also in external characters approach the following group, that of the true Sea Snakes) venture out to sea. They feed on fishes, frogs, crustaceans, and other water animals, and are viviparous. Not any of them are venemous.
V. Sea Snakes, distinguished by a strongly compressed tail, and by the position of the nostrils, which are placed as in the last group. They live in the sea, only occasionally approaching the land, feed on marine fishes, are viviparous and venemous. One genus only (Platurus) has the ventral shields so much developed as to be able to move on land. No Oceanic Serpent is known of gigantic dimensions, such as is currently alleged to have been seen by unscientific observers. 44
"Although these five groups," remarks Dr. Günther, "are not separated from each other by defined lines of demarcation, and frequently pass into one another by intermediate forms, yet a family and genus which should be composed of species of several of these groups would be a very unnatural assemblage of heterogeneous forms."
It is also remarked by the same naturalist that there is no sharp boundary line between the order of Snakes and that of Lizards. There are various limbless Saurians of Ophidian appearance, but the systematic position of which is decided by the structure of their jaws. The Common Orvet, or Slow-worm, is a familiar instance. On the other hand, certain Ophidians remind us, by several characters, of the Saurian type,—as the Snakes constituting the families Typhlopidæ, Tortricidæ, Xenopeltidæ, and Uropeltidæ, which are distinguished by polished, closely adherent, rounded, sub-equal scales, much resembling the smooth scales of various Scincoid Lizards; most of them have a very narrow mouth, unlike the enormous gape of the typical Serpents, and some are without that longitudinal fold in the median line of the chin which is so characteristic of most Ophidians; moreover, most of them have rudiments of the bones of a pelvic arch. "The reason," alleges Dr. Günther, "why we adopt the view of those systematists who refer such reptiles to the Ophidians, instead of associating them with the limbless Scincoid Lizards, is the loose connection of the jaw-bones, a character which must be considered as peculiar to the Ophidians, and which is only somewhat less developed in the families mentioned than in the typical forms. The two halves of the lower jaw in Ophidians, namely, are not united by a bony symphysis, but by an elastic ligament. The peculiar mobility of the jaw bones enables the Snakes to extend the gape in an extraordinary degree, and to work their prey down through the collapsed pharynx."
The same naturalist classifies the Ophidia into three sub-orders, in which the venemous Snakes are separated from the others; but to some herpetologists this arrangement must appear rather forced, as his Venemous Colubrine Snakes have certainly a much nearer resemblance in other respects to the Colubridæ than they have to the Viperine Snakes. For the most part, these reptiles are provided 45 with numerous teeth, which are lengthened, conical, thin and pointed like a needle, and more or less bent backwards.
In Dr. Günther's first sub-order, that of Non-venemous Snakes, the teeth are either entirely smooth, or only the last of the maxillary series is provided with a faint longitudinal groove, which is not intended to convey a virus into the wound, the groove appearing rather to increase the strength of the tooth. Many of them have long teeth in front of the jaws or of the palate, but these are never grooved or perforated, and only serve to afford a firmer hold on the living and struggling prey.
"The structure of the venom-tooth is not the same in all poisonous Snakes: in some it is fixed to the maxillary bone, which is as long or nearly as long as in the non-venemous Snakes, and generally bears one or more ordinary teeth on its hinder portion. The venom-tooth is fixed more or less erect, not very long, and its channel is generally visible as an external groove. The poisonous Snakes with such a dentition have externally a more or less striking resemblance to the non-venemous Serpents, and on this account they are designated as Venemous Colubrine Snakes, forming our second sub-order." Two very distinct families are here brought together—viz. the Elapidæ (which comprises the Cobras and many others), and the Hydrophidæ (or Sea Snakes).
"In the other venemous Snakes, composing the third sub-order, the maxillary bone is extremely short, and does not bear any teeth except an exceedingly long fang, with a perfectly closed externally invisible channel in its interior. Although this tooth also is fixed to the bone, the bone itself is very mobile, so that the tooth, which is laid backwards when at rest, can be erected the moment the animal prepares to strike. This tooth or fang, like all the other teeth, is not only occasionally lost, but appears to be shed at regular intervals. From two to four other venom-fangs in different stages of development, destined to replace the one in action, exist between the folds of the gum, and are not anchylosed to the bone." The more characteristic venemous Snakes appertain to this sub-order—viz. the two families Crotalidæ (comprehending the Rattlesnakes, the Fer-de-lance, &c.) and Viperidæ (comprising the Vipers, Puff-adders, &c.).
Let it be particularly borne in mind that the supposed distinguishing 46 characters of all poisonous Snakes, as assigned by sundry mischievously ignorant writers, are those of the third of the foregoing sub-orders almost exclusively. Even the broad, flat, and lanceolate form of head is exemplified in certain Tree Snakes of the non-venemous genus Dipsas, and not in the Cobras and others that are quite as deadly—e.g. Hoplocephalus, Bungarus, Naja, Elaps, and others constituting the Colubriform family Elapidæ.
These are distributed by Dr. Günther under numerous families, of which we can only notice the more prominent, and some of the more conspicuous species, in a popular exposition.
The Typhlopidæ, or Blind Snakes, comprise forms which are the most remote from the true Ophidian type. They live under ground, their rigid body and short curved tail being adapted for burrowing. After showers of rain they occasionally appear above ground, and then they are tolerably agile in their serpentine movements. The eye, which is scarcely visible in many species, can give to them only a general perception of light. They feed on worms and small insects, the tongue being forked, and, as in other Snakes, frequently exserted. They are oviparous. The smallest species of Snakes belong to this family, some of them being only half the size of a common earth-worm, to which they bear a superficial resemblance. Such, indeed, are the small vermiform Snakes already referred to, as being foolishly considered venemous by most natives of India. Species of this family inhabit almost every country within and near the tropics.
The Tortricidæ are akin to the Typhlopidæ, and have rudiments of hind limbs hidden in a small groove on each side of the vent, also a longitudinal fold at the chin. The "Coral Snake" of Demarara (Tortrix scytale) appertains to this family; and the genus Cylindrophis, different species of which inhabit the great Asiatic archipelago, with the island of Ceylon.
The family Xenopeltidæ consists of a single species only, so far as hitherto known, the Xenopeltis unicolor, which is common in the Indo-Chinese and Malayan countries. It grows to three or four feet in length, and when alive is uniformly steel-blue, 47 most beautifully iridescent, beneath white; but the blue fades to brown after long immersion in spirits. Young examples have a white collar. Mr. W. Theobald remarks of it that "this Snake is common in Lower Pegu and the Tenasserim provinces, and is very malignly beautiful, though of repulsive physiognomy. The skin is loose and thick, and its habits are nocturnal. The following illustrates its ferocious nature:—I once remarked a Colubrine Snake (Ptyas mucosa), some five feet in length, in the hedge of the Circuit-house of Bassein. On running downstairs, the Snake had vanished, but on searching for it I saw its tail sticking out of a hole beneath a wooden plant-case. Do what I might I could not drag it out, as it seemed held fast within. I therefore, with some trouble, overturned the plant-case, and then saw that the unlucky Colubrine Snake was firmly pinned by a large Xenopeltis, into whose hole it had unwittingly entered. The Xenopeltis seemed about four feet in length; but, on perceiving itself uncovered, released its hold of the Ptyas and made its escape." The Xenopeltis preys chiefly on small mammalia, which it hunts for in their subterranean holes; and in some respects it approximates the Pythonidæ.
The Uropeltidæ, or Shield-tails, constitute a very curious family of Burrowing Snakes, which bear considerable resemblance to the Typhlopidæ, but have a very peculiar, short, strong, posteriorly shielded tail, adapted for working their way below the surface. The species are mostly small, and hitherto they have been found chiefly in Ceylon, but a few also in the peninsula of India. They are by no means scarce, but escape observation from their peculiar mode of life. Dr. Kelaart remarks that "they are timid creatures, seldom making their appearance above ground; living chiefly in ant-hills or dunghills, sometimes also several feet deep in rich loamy soil. They feed on ants, small earth-worms, and the larvæ of insects, and at least one species has been ascertained to be viviparous. Five genera and eighteen species of them are recognised."
The Calamaridæ form an extensive family of diminutive slender Snakes, from one to two feet in length, many species of which inhabit both the Old World and the New, though the same kinds are not found both East and West. They keep to the ground, beneath stones, fallen trees, &c.; and their food appears to consist chiefly of insects. They are gentle, and never attempt 48 to bite, and themselves very commonly become the prey of the smaller Elapidæ, certain of which indeed bear considerable resemblance in appearance to the Calamaridæ, but are readily distinguished by possessing the poison-fangs.
The Oligodontidæ are another extensive family of small ground Snakes, which are peculiar to South-eastern Asia and its great archipelago. They conduct to the terrene genera of the great family Colubridæ.
The Colubridæ are divided by Dr. Günther into ground Colubrines (Coronellinæ), true Colubrines (Colubrinæ), bush Colubrines (Dryadinæ), and fresh-water Colubrines (Natricinæ); and he remarks that "they are found in every part of the temperate and tropical regions, but are only scantily represented in Australia and in the islands of the Pacific. The species are so numerous and show such a gradual passage between extreme forms, that, although genera can be easily characterized, it is almost impossible to distinguish wider groups by definite characters." Among them the Coronellinæ approximate the immediately preceding families, and, like them, live on the ground, and are not generally of brilliant colouring, though a few species which frequent grassy plains are of a bright green colour. The Colubrinæ "form, as it were," writes Dr. Günther, "the nucleus of the whole sub-order of innocuous Snakes: they are typical forms, not characterized by the excessive development of some particular organ, but by the fairness of the proportions of all parts. Yet some of them have a more slender body than others which always live on the ground; they are land Snakes, but swim well when driven into the water, or climb when in search of food. They are of moderate or rather large size." In the Dryadinæ the form is elongate and somewhat compressed, indicating their climbing propensities; they have the body not so excessively slender as in the true Tree Snakes, to which they lead off. They are much more numerous in the New World than in the Old, and their ground-colour is very commonly green. The Natricinæ are generally not very elongate or compressed, and most of them have keeled scales. They freely enter the water in pursuit of their food, which consists chiefly of frogs and fishes. All the Snakes of the preceding three sub-families overpower their prey by throwing 49 some coils of the body round or over it, and commence to swallow it only after it has been smothered, or at least exhausted; but the Natricinæ swallow their prey immediately after they have seized it.
Of the sub-family Coronellinæ, one species of the typical genus Coronella is widely diffused over Europe, and has only of late years been recognised as an inhabitant of the British Islands, the Coronella austriaca. Another, C. girondica, occurs in Italy. Others are found in Africa, America, and Australia. The C. austriaca has somewhat the appearance of the common Adder, for which it is often mistaken; but it is non-venemous, though rather a fierce reptile, which bites and holds on; and as it occurs in Malta (where no venemous species is known to exist), it is doubtless the supposed Viper which seized upon the apostle Paul. Several other genera are recognised.
Of the Colubrinæ, Rhinechis scalaris, Coluber æsculapii, C. quadrilineatus, Elaphis quater-radiatus, and three species of Zamenis inhabit Europe: there are five of Coluber in North America, and the well-known "Black Snake" of the Anglo-Americans is the Coryphodon constrictor. Other species of Coryphodon or Ptyas inhabit South-eastern Asia, as the different "Rat Snakes" of Anglo-Indians, of which Ptyas mucosus is particularly common in India, where it is encouraged by reasonable people as a destroyer of the far more troublesome Brown Rat (Mus decumanus).
The Dryadinæ are chiefly American, and do not call for particular further remark; but the Natricinæ are very numerous, and there are three species in Europe of its most prominent genus, Tropidonotus—viz. T. natrix, T. hydrus, and T. viperinus. [Dr. Günther gives as many as twenty-one species of this genus as inhabitants of the Indian region alone, and there is reason to believe that that number is far from being complete. Others inhabit North America and North-western Australia, and some generic groups have been detached that are not very conspicuously separable.]
The Ringed Snake, Tropidonotus natrix, is often found in fine seasons near human habitations. It deposits its eggs, which are fifteen to twenty in number, commonly in dunghills, in one agglutinated mass. Exposed to the air, these eggs soon shrivel and dry, and the embryos within them perish. The Ringed Snakes are also found near rivers and meadows, by the side of water-courses, into 50 which they love to plunge; hence they are sometimes called Water Serpents, Swimming Serpents, Hedge Eels, and other provincial synonyms. They sometimes attain to as much as and more than a yard in length. The summit of their head is covered with nine large scales, disposed in four rings. The upper part of the body is of a more or less darkish grey colour, marked on each side with irregular black spots. Between the two rows of spots are two other longitudinal rows, which extend from the head to the tail. The belly varies from black to a bluish white. Upon the neck are two whitish or pale yellowish spots, which form a kind of half collar or ring, from which its name is derived; these two spots become much more apparent from being contrasted with two other very dark triangular spots placed near them. They prey upon lizards, frogs, and mice, and they even surprise young birds, and devour the eggs in their nests, for they climb trees with facility. Towards the end of the autumn they seek the warmest places, approaching near to houses; or they retire into subterranean holes, often at the bottom of some hedge, which is almost always in an elevated place, secure from inundations. The Ringed Snake is found in nearly all European countries, and can be handled without danger. Lacépède gives some interesting details, showing the gentleness of its habits. They 51 are easily tamed, and can be kept in houses, where they soon accustom themselves to those who have the care of them. At a sign from their keeper, they will twist themselves round his fingers, arms, and neck, insinuate their heads between his lips to drink his saliva, and to hide and warm themselves they creep under his clothes. In their wild state, the adult Ringed Snake lives in the fields; and, when full-grown, shows great irritation when attacked. When exasperated, they move their tongues, erect themselves with great vivacity, and even bite the hand which tries to seize them; but their bite is quite harmless.
[This Ringed Snake is the Natrix torquatus of Ray, well known to naturalists. The female is larger than the male. Its food consists a good deal of frogs, which are generally caught by the leg, and swallowed alive, in spite of resistance and very distressing cries.
When the skin has just been cast, the Ringed Snake presents beautiful markings, especially when seen swimming across some clear running stream, its head and neck raised above the limpid water, and the sun shining on its bright enamelled skin. It has been supposed, not unnaturally, that the Snake casts its skin at fixed intervals; this, Mr. Bell considers to be a mistake. He has always found that it depended on the temperature of the atmosphere and on their state of health and feeding. "I have known the skin thrown off" he adds, "four or five times during the year. It is always thrown off by reversing it, so that the transparent covering of the eyes and that of the scales are always found in the exuviæ. Previous to this curious phenomenon, the whole cuticle becomes somewhat opaque, the eyes dim, and the animal is evidently blind. It also becomes more or less inactive, until at length, when the skin is ready for removal and the new skin perfectly hard underneath, the animal bursts it at the neck, and creeping through some dense herbage or low brushwood, leaves it detached, and comes forth in brighter and clearer colours than before."
The Ringed Snake begins to hybernate, in some warm hedge or under the root of some tree, or other sheltered situation, about the end of autumn; and there they coil themselves up, sometimes in numbers, till the spring again calls them forth. Many instances are told of this Snake being tamed. Mr. Bell had one which knew him from all other persons; it would come to him when let out of 52 its box, and crawl under the sleeve of his coat, and every morning come to him for its draught of milk.]
The Green and Yellow Snake is also about a yard in length, and is common in the south and west of France; they have been taken in the forest of Fontainebleau. The beautiful colours in which they are clothed causes them to be easily distinguished from the Viper. The eyes are edged with golden-coloured scales; the upper part of the body is of a very dark greenish colour, upon which is extended a large number of radiating lines, composed of small yellowish spots of different shapes, some long, others lozenge shape, giving it a chequered appearance. These chequers extend from the head to the tail. The belly is yellowish; the large plates which cover it have a black spot at each end, and are bordered with a very thin black line. This inoffensive reptile is extremely timid, and generally hides itself from observation, taking to flight at the least alarm. They are said to be easily tamed.
The Viperine Snake (Fig. 12) has the body of a greyish or dirty yellow colour, having on the middle of the back a series of blackish spots so close to each other as to give the idea of one small continuous wavy line from head to tail. The sides are covered with isolated spots, forming lozenge-like figures, the centres of which are of a greenish tint. This is the smallest of all 53 the European Colubridæ, and, like the others, it is found in most parts of Europe.
[The Psammophidæ, or Desert Snakes, are akin both to the Colubridæ and to the Tree Snakes of the next family; but the latter, remarks Dr. Günther, may always be distinguished either by their green coloration, by the horizontal pupil to the eye, or the absence of a long, anterior, maxillary tooth. In the Psammophidæ the pupil of the eye is round or vertical. Most of the species of this family belong to the fauna of tropical Africa, which also produces a slender form (in Psammophis elegans). The other species are of a stouter habit, frequenting plains, or at all events living on the ground. Of the Indian Psammophis condanarus, Dr. Jerdon procured one which had killed and was swallowing a small Viper (Echis carinata), this being one of the few instances in which a non-venemous Snake has been known to overpower a poisonous one. We have heard the same of a small Boa-like Serpent (Chilabothrus?) in the West Indies, which is said to prey upon the formidable Crotalidæ. The Psammodynastes pulverulentus has a wide geographical range over South-eastern Asia and its islands. Although innocuous, it has the aspect of a venemous species.
In a kindred African family, the Rachiodontidæ, the species of Dasypeltis have the maxillary teeth minute and few in number (four to seven); but they have also some remarkable gular teeth, which are formed by the elongated inferior spinous processes of the hinder cervical vertebræ. The object of the latter is to crush the shells of birds' eggs, upon which the Snakes in question habitually feed.
Of the more characteristic Tree Snakes, the Dendrophidæ have the body and tail much compressed, or very slender and elongated; the head generally lengthened, narrow, flat, and distinct from the slender neck; the snout rather long, obtuse or rounded in front; cleft of the mouth wide; and the eye of moderate size, or large, with round pupil. These are Diurnal Snakes, which live entirely upon trees, where they prey chiefly on arboreal lizards and frogs. Species of them inhabit all tropical countries. They are mostly of great beauty, and the Indian Chrysopelea ornata is excessively so, being variegated with yellow and crimson upon a black ground; 54 but the crimson soon fading when a specimen is immersed in spirit. Others are very variable in their colouring, as the African Bucephalus capensis and the Indian Dendrophis picta.
The next family of Dryiophidæ, or the Whip Snakes, have a still more slender and elongated body, which has been aptly compared to the thong of a whip. The head is very narrow and long, with tapering snout, ending in a protruded rostral shield, which is sometimes modified into a flexible appendage; eyes of moderate size, and all the Asiatic species have the pupil of the eye horizontally linear, and a long fang-like tooth in the middle of the maxillary. The whole of this group are provided with a posterior grooved tooth. They are chiefly nocturnal, and their movements are wonderfully rapid and graceful among the branches of trees. They are numerous almost everywhere in tropical countries. In general the various Whip Snakes are of a bright leaf-green colour, with two white stripes on the belly, so that they are difficult to discern among the foliage. In the genus Langaha, which is peculiar to Madagascar, the muzzle is elongated into a fleshy appendage, which is covered with small scales, constituting about one-third of the total length of the head. This appendage is dentated in one species (L. crista-galli), and not so in another (L. nasuta). In the Indian genus Passerita the snout is long and pointed, terminating in a flexible appendage. The name of Whip Snake is applied by Anglo-Indians to all of the species of Dendrophidæ and of Dryiophidæ, and the erroneous notion prevails that they are highly venemous, and that they spurt venom into people's eyes. The same is believed in South Africa of the Bucephalus capensis. Even Gordon Cumming asserts that one night a Snake which his servant had tried to kill with his loading-rod flew up at his eye, and "spat poison into it. Immediately," he adds, "I washed it well at the fountain. I endured great pain all night, but next day my eye was all right."12
55
Of a beautiful green species (Philodryas viridissimus), appertaining to the family of Dendrophidæ, in Brazil, Dr. Wurcherer writes:—"I am always delighted when I find that another Tree Snake has settled in my garden. You look for a bird's nest, the young ones have gone, but you find their bed occupied by one of these beautiful creatures, which will coil up its body, of two feet in length, within a space not larger than the hollow of your hand. They appear to be always watchful; for at the instant you discover one, the quick playing of the long, black, forked tongue will shew you that you too are observed. On perceiving the slightest sign of your intention to disturb it, the Snake will dart upwards through the branches and over the leaves, which scarcely appear to bend beneath the weight. A moment more, and you have lost sight of it." Some of the true Whip Snakes attain to six or seven feet in length, or even more; and with reference to the vague application of vernacular names (vide p. 42), it may here be remarked that the "Little Whip Snake" of the Australian colony of Victoria denotes a poisonous Snake of a very different family (the Hoplocephalus flagellum).
The Dipsadidæ are a numerous family of tropical Tree Snakes, which also have a much compressed body, but short and triangular-shaped head, which is broad behind; the eye large, having generally a vertical pupil. Some of them attain to six or seven feet in length, and all live on warm-blooded animals. It is remarkable that certain of the species prey on birds solely, whilst others attack only mammalia. Their coloration varies a good deal, and species of them inhabit most tropical and subtropical countries.
The Lycodontidæ are an extensive family of small Ground Snakes, inhabiting Africa and tropical Asia, which have the body generally of moderate length, or rather slender, and the head also of moderate length and width, with generally a depressed, flat, and somewhat elongated muzzle; maxillary with a fang-like tooth in front, but without a posterior grooved tooth. The African species feed on Mice and other small nocturnal mammalia; while the Indian species (which have a vertical pupil) prey chiefly, if not wholly, on the smaller Scincoid Lizards, which they would appear to follow into the place of their retreat. Lycodon aulicus 56 is one of the commonest Snakes of the Indian region, and is quite harmless, though often ignorantly supposed to be dangerously poisonous.
The Amblycephalidæ, or Blunt-heads, comprise a few species of moderate or small size, akin to the Dipsadidæ, but the narrow mouth of which necessitates their feeding on insects, and they live on trees and bushes, or under the roofs of huts. Of the Indo-Chinese and Malayan Amblycephalus boa, Dr. Günther remarks that "the head of this most singular Snake resembles much that of a mastiff, the lips being arched and tumid. It climbs with great facility, frequenting the roofs of the natives' huts in pursuit of its insect food. It attains to a length of three feet, the tail being a third." Of a second genus, Pareas, three species inhabit the same region.
The Pythonidæ, or Pythons, and Boas, are celebrated for the enormous magnitude to which some of the species attain. These are emphatically the great constrictor Serpents, to all of which the name of Boa-constrictor is popularly applied, although this appellation refers properly to one only of them which is peculiar to South America. Various genera of them inhabit Africa, South-eastern Asia and its islands, Australia, and South America, with the West Indies.]
The Pythons are large Serpents of Asia and Africa. They live in marshy places, and near the margins of rivers. They are non-venemous, but possessed of immense muscular power, which enables some of the species to kill, by constriction, animals of much larger circumference than themselves.
Aristotle tells us of immense Lybian Serpents, so large that they pursued and upset some of the triremes of voyagers visiting that coast. Virgil's Laocoon, so vividly represented in the well-known marble group, owes its origin, no doubt, to the descriptions current of constricting Serpents. Quoting Livy, Valerius Maximus relates the alarm into which the Roman army, under Regulus, was thrown by an enormous Serpent, having its lair on the banks of the Bagradus, near Utica. This Serpent Pliny speaks of as being a hundred and twenty feet long. But, without multiplying instances to which time has lent its fabulous aid, and coming to more modern times, Bontius speaks of Serpents in the Asiatic 57 islands as beings so various that he despairs of even enumerating them all. "The great ones," he says, "sometimes exceed thirty-six feet, and have such capacity of throat and stomach, that they swallow entire Boars." Adding that he knew persons who had partaken of a Hog cut out of the stomach of a Serpent of this kind. "They are not poisonous," he adds, "but they strangle by powerfully applying their folds round the body of their prey." Mr. M'Leod, in his interesting voyage of the Alceste, states that during a captivity of some months at Whidah, on the coast of Africa, he had opportunities of observing Serpents double this length, one of which engaged a negro servant of the governor of Fort William in its coil, and very nearly succeeded in crushing him to death. There can be no doubt that the length is here much exaggerated. About thirty feet is the utmost length attained by the most gigantic Serpents of which we possess accurate knowledge.
The body of the Python is large and round. They live on trees in warm damp places, on the banks of streams or water-courses, and attack the animals which come there to slake their thirst. Hanging by the tail to the trunk of a tree they remain immovable in their ambush until their opportunity comes, when they dart upon their prey, fold their bodies round it with amazing rapidity, and crush it in their monstrous folds. Animals as large as Gazelles, and even larger, thus become their victims. Their jaws are extremely distensible, as we have seen; for, having neither breast-bone nor false sides, they can easily increase the diameter of the opening, so as to swallow the most voluminous prey.
The Ophidians (as we have seen) surpass all other Reptiles in the number of their vertebræ, with incomplete hæmal arches; these constitute the skeleton of the long, slender, limbless trunk. All these vertebræ coalesce with one another, and are articulated together by ball-and-socket joints. Besides this articulation to the centrum, the vertebræ of Ophidians articulate with each other by means of joints which interlock by parts reciprocally receiving and entering one another, like the tenon-and-mortise joint in carpentry. "The vertebral ribs have an oblong articular surface, concave above and almost flat below, in the Python. They have a large medullary cavity, with dense but thin walls, with a fine 58 cancellated structure at their articular ends. Their lower end supports a short cartilaginous membrane, closing the hæmal arch, which is attached to the broad and stiff abdominal scute. These scutes, alternately raised and depressed by muscles attached to the ribs and integuments, aid in the gliding movement of serpents."
The peculiar motion of Snakes was first noted by Sir Joseph Banks, and commented on by Sir Everard Home. Sir Joseph was observing a Coluber of unusual size, and thought he saw its ribs come forward in succession, like the feet of a caterpillar. To test this, he placed his hand under the animal, the ends of the ribs were distinctly felt pressing upon the surface in regular succession, leaving no doubt that the ribs formed so many pairs of levers, by means of which it moves its body from place to place.
The muscles which bring forward these ribs, according to Sir Everard, consists of five sets. One from the transverse process of each vertebra and the rib immediately behind it, which rib is attached to the next vertebra. The next set goes from the rib near the spine, and passes over two ribs, sending a slip to each, and is inserted into a third, a slip connecting it with the next muscle in succession. Under this is a third set, issuing from the posterior side of each rib, passing over two ribs, and sending a lateral slip to the next muscle, and is also inserted in the third rib behind. And so on throughout the five sets of muscles.
On the inside of the chest there is a strong set of muscles attached to the anterior surface of each vertebra, and passing obliquely forward over four ribs is inserted into the fifth one only in the centre. From this part of each rib a strong flat muscle comes forward on each side, before the viscera, forming the abdominal muscles and uniting in a middle tendon, so that the lower half of each rib which is beyond the origin of this muscle, and which is only laterally connected to it by a loose cellular membrane, is external to the belly of the animal, and is used for the purpose of progressive motion, while that half of each rib which is next the spine, as far as the lungs extend, is employed in respiration.
These observations of Sir Everard Home apply to all Snakes; but the muscles were compared with a skeleton of the Boa-constrictor 59 in the Hunterian Museum, which is thirteen feet nine inches in length. The habit of attaching themselves to trees, and holding on by the tail, their heads and bodies floating listlessly on some sedgy river, is explained by the structure of the tail. Dr. Meyer has minutely described the manner in which they hook themselves on to a tree, which gives them the power of a double fulcrum. The apparatus which gives this power is a spur or nail on each side of the vent in the Pythonidæ, in which the anatomist discovered the elements of an unguinal phalanx articulated with another bone much stronger, which is concealed under the skin.
Following the arrangement of the Pythonidæ, adopted by Dr. J. E. Gray in the Catalogue of the British Museum, we find:—
I. Morelia, having a strong prehensile tail, distinct head, truncate muzzle, crown of the head with small shield-like plates. Of this genus there are two species. The Diamond Snake (M. spilotes), a native of Australia, and of a bluish-black colour; and the Carpet Snake (M. variegata), from Port Essington and Swan River. It is whitish, with irregular black-edged olive spots, and an olive head, with two or three white spots in the centre of the crown.
II. Python, having the crown shielded to behind the eyes.
Of this genus there are two species, which have sometimes been referred to the Boas. The Pythons bear the same general appearance. Upon their bodies is traced a sort of blackish-brown chain, presenting nearly quadrangular links upon a clear yellowish ground, extending from the nape of the neck to the extremity of the tail. The suscephalous region is partly covered by a large brownish-black spot. Upon each side of the head is a black band, which frequently extends from the nostril, passing by the eye, as far as, and up to, the commissures or corners of the lips.
P. reticulatus, the Ular Sawad of the Malay countries, found also in Burmah and Siam, has the four front upper labial plates pitted; the frontal plate simple; the head has a narrow, longitudinal, brown stripe. This is one of the most handsomely marked species of the whole family, its body being covered with a gay lacing of black and golden yellow. It is said to attain the great length of thirty feet, and is stout in proportion. In its native wilds 60 the powers of this gigantic reptile are said to be enormous, being able to subdue a full-grown Buffalo; and even a Man has been said to fall a prey to its fury. A Malay prao had anchored for the night under an island of the Celebes. One of the crew had gone ashore in search of the favourite betel nut, and is supposed on his return to the beach to have fallen asleep. In the dead of the night his comrades were roused by his screams; they pulled ashore with all expedition, but came too late; the cries had ceased, and the wretched man had breathed his last in the folds of one of these enormous Serpents. They killed the creature, cut off the head, and carried it, together with the lifeless body of their comrade, to the vessel. The right wrist of the corpse bore the mark of the Serpent's teeth, and the disfigured body showed that the man had been crushed by the constrictive folds of the reptile round the head, breast, and thighs. The Ular Sawad arranges its eggs by placing them in a group, which is covered by the body. This statement, first made by Mr. Bennett, has been confirmed by the observations of M. 61 Lamare Picquot, and by observations on other species of Python in the Jardin des Plantes, Paris, and in the London Zoological Gardens.
The Rock Snake of India and Ceylon (P. molurus) is another species to which the name of Boa-constrictor has been given. It has the two pairs of front upper, and three hind lower labial shields pitted, and the frontal plates double. Of this gigantic Serpent several specimens are generally to be seen in the Zoological Gardens.
III. Hortulia, having the upper and lower labial shields deeply pitted; muzzle and forehead with symmetrical shield; nostrils lateral. They are natives of Africa, and three species are known, namely, the Natal Rock Snake, having the lower labial shields deeply pitted, the muzzle and forehead with symmetrical shields, the nostrils lateral; the Guinea Rock or Fetish Snake (H. Sebæ), closely resembling the last in many structural points; and the Royal Rock Snake (H. regia), having the four pairs of the upper front labials pitted, the upper ocular plate single, the lower labial shields four in number and broad.
The Royal Rock Snake inhabits Western Africa. It is black in colour, marked on the middle of the back with a series of oblong white spots, the sides being marked by another series of large white spots, with one or two black spots in the upper part; the head black, with a streak over the nostrils and the top of the eyes, another from the lower edge of the eye, the lips and chin beneath are white.
The Natal Rock Snake (H. natalensis, Fig. 13) is described by Sir Andrew Smith as being gigantic in size, he having seen a skin measuring twenty-five feet, although part of the tail was absent. "It feeds," he says, "on small quadrupeds; and for some days after swallowing one it remains in a torpid state, when it may be easily destroyed." Of this opportunity, however, the South Africans never avail themselves; they have a horror of the reptile, but believe that it has an influence over their destinies, and affirm that no one has ever been known to kill one and prosper.
The Guinea Rock or Fetish Snake (H. Sebæ, Fig. 14) is typical of the genus, and has also been referred to the Boa-constrictor, and closely resembles the Natal Rock Snake. It is 62 a native of the warmer parts of Africa. A living specimen at the Zoological Gardens is estimated to weigh a hundredweight.
Of the genera Liasis and Nardoa there are five species, very imperfectly known.
IV. Epicrates, an American and West Indian species, having the crown scaly; the forehead with symmetrical shields.
The Aboma (E. cenchria) is one of the largest of the group, sometimes attaining dimensions quite gigantic. It is yellowish in colour, with a row of large brown rings running the whole 63 length of the back, and variable spots on the sides; these are generally dark, with a whitish semi-lunar mark. This formidable Reptile has all the habits of its congeners; it is found in the marshy swamps of tropical America, and near the rivers, where it lies in wait for its prey.
The Boas, properly so called, have the scales smooth; labial shields smooth, not pitted; the body compressed, tapering to the tail, which is long and prehensile; the head is comparatively small, being enlarged behind, and contracted towards the muzzle, which is rather short. The crown is covered with scales; the nostrils lateral, between two plates. Four species of this genus are recognised by naturalists, all of which have been described by travellers as the true Boiguacu, or Boa-constrictor of Linnæus. This species has the scaly circle of the orbit separated from the upper labial plates by one or two series of scales. A large chain consisting of blackish hexagonal spots, alternating pale oval stains, notched and jagged, extending the whole length of the back, and forming a very elegant design. This species seems to be strictly confined to tropical America. Humboldt found it in Guiana, and the 64 Prince de Wied observed it in Brazil. All the specimens in the British Museum are from that part of the New World. This is supposed to be the Tlicoatl and Temacuilcahuilia (the words meaning "fighting with five men"), described by Hernandez, the latter name being derived from its size and strength. "It attacks," he says, "those it meets, and overpowers them with such force, that if it once coils itself round their necks, it strangles and kills them, unless it bursts itself by the violence of its own efforts." The same author states that he has seen Serpents as thick as a man's thigh, which had been taken when young by Indians and tamed. That this Boa attains an immense size is a well-established fact. Shaw mentions a skin in the British Museum, in one of his lectures, which measured thirty-five feet in length.
Three other species—the Lamanda (B. diviniloqua), from Santa Lucia; the Emperor (B. imperator), a native of Mexico; and B. eques, the Chevalier Boa of Peru—are all to be occasionally seen in the Zoological Gardens.
The Boa anaconda, more properly Eunectes murinus, is also a native of tropical America. The name of Anaconda has become well known through Mr. Lewis's celebrated tale, so called, in which its predatory habits are displayed in such a manner as to enthral and fascinate the reader, as the author makes the reptile fascinate its victim. The name, Mr. Bennett tells us, is of Cinghalese origin, and is popularly applied to all very large Serpents. This species is of a brownish tint, with a double series of colours extending from head to tail; the sides are covered with annular spots with white disks surrounded by blackish rings. Seba has represented this creature lying in wait for Mice; but this is probably the prey of the young Anaconda. Another provincial name, "El Troga Venado" (the Deer Swallower), is probably applied to the matured Reptile.
The following description of the actions of one of these large non-venemous Serpents, which accompanied a specimen sent to the United Service Museum, by Sir Robert Ker Porter, is probably a fair description of the habits of all the large Pythonidæ:—"This species is not venemous, nor is it known to injure man (at least not in this part of the New World); however, the natives of the plain stand in great fear of it, never bathing 65 in waters where it is known to exist. Its common haunt, or rather domicile, is invariably near lakes, swamps, and rivers; likewise close and wet ravines produced by inundations of the periodical rains. Fishes, as well as other animals which repair there to drink, are its prey. The creature lurks watchfully under cover of the water, and, while the unsuspecting animal is drinking, suddenly makes a dash at its nose, and with a grip of its back-reclining range of teeth, never fails to secure the terrified beast beyond the power of escape. In an instant the sluggish waters are in turbulence and foam. The whole form of the Serpent is in motion; its huge and rapid coilings soon encircle the struggling victim, and but a short interval elapses ere every bone in the body of the expiring prey is broken." Sir Robert then describes the manner in which the prey is swallowed, being previously lubricated by the Serpent's saliva; but Professor T. Bell, after carefully watching the constricting Serpent's mode of swallowing its prey, asserts that this is a delusion. "The mucus is not poured 66 out till it is required to lubricate the dilated jaws and throat for the seemingly disproportionate feat."
[The small, but very distinct family of Erycidæ have the body of moderate length, cylindrical, covered with small and short scales; the tail very short, with only a single series of subcaudal scales; head somewhat elongate; eye rather small, with vertical pupil. Adult individuals have, like the Pythons, a short conical prominence in a groove on each side of the vent; this being the extremity of a rudimentary hind limb. "The Snakes of this family," remarks Dr. Günther, "shew great similarity to the Pythons and Boas, with regard to their internal structure as well as to their external characters. But their tail is very short, not flexible, and much less prehensile; and whilst the Serpents just mentioned are more or less arboreal, frequenting marshy places with luxuriant vegetation, the Erycidæ inhabit dry, sandy, or stony plains, burrowing with the greatest facility below the surface, and entering crevices and holes in search of their prey, which consists of Mice, Lizards, and other burrowing Snakes. Probably they are semi-nocturnal, and able to see in dark places as well as in the night. They are found in Northern Africa, in the islands of the Mediterranean, in the arid parts of India, and probably in Arabia; two species are known to have been brought from Sikhim."
The Cursoria elegans is said to be from Afghanistan; Eryx iacalus inhabits Greece and Egypt; and there is also E. thebaicus in the latter country, and E. Johnii in India. Another Indian species is the Gongylophis conicus, which the natives erroneously persist in declaring to be venemous. The Eryx Johnii is frequently found in the possession of the serpent-charmers of its native country, who mutilate the end of its short, thick tail in such a manner that the scarred extremity somewhat resembles the form of the head. Such specimens are shewn as deadly Two-headed Snakes, and, as such, are occasionally brought alive to Europe. An example of this species lived in the London Zoological Gardens for about eight years, and fed regularly on young Mice. The keeper assured Dr. Günther that it frequently covered its prey with saliva. It always kept itself hidden below the gravel 67 at the bottom of its cage. This species attains to a length of nearly four feet, the tail measuring but four inches.
The Acrochordidæ constitute a very remarkable small family, of which one genus is terrene, and another highly aquatic in its habits. Whether a third genus, the Javanese Xenodermus, should be referred to it, is doubtful in the opinion of Dr. Günther. These Snakes have the body of moderate length, rounded, or slightly compressed, and covered with small wart-like, not imbricate, tubercular or spiny scales; tail rather short, prehensile; head rather small, not distinctly separated from the neck, and covered with scales like those of the body; nostrils close together, at the top of the snout; teeth short, but strong, of nearly equal size, and situate both in the jaws and on the palate. These serpents are viviparous. One of them, Acrochordus javanicus, inhabits Java and the Malayan peninsula, where it is considered rare. It grows to a length of eight feet, and its habits are terrene. The late Dr. Cantor justly compares its physiognomy to that of a thorough-bred bull-dog; a female in his possession brought forth no fewer than twenty-seven young in the course of about twenty-five minutes; they were active, and bit fiercely. Hornstedt found a quantity of undigested fruits in the stomach of this Serpent! Upon which Dr. Günther remarks that no opportunity of making further observations on the habits of this remarkable Snake should be lost. The aquatic member of this family, Chersydrus granulatus, inhabits from the coasts of India to those of New Guinea and the Philippine Islands. Sometimes it is met with at a distance of three or four miles from the shore. Mr. W. Theobald remarks that it is plentiful in the Bassein River (in British Burmah), in salt water below Gnaputau, and, with various other Sea Snakes, is frequently swept by the tide into the fishing baskets of the natives. The ebb-tide, running like a sluice, sweeps various Fishes, Crustaceans, Snakes, and even Porpoises occasionally, into the broad mouths of those baskets, where they are at once jammed into a mass at the narrow end of the creel. "The Chersydrus," he adds, "is more nearly connected with the Hydrophidæ than with the next family, being as essentially aquatic as any of the former, to which, save from its wanting the poison-gland, it might be appropriately 68 referred. Indeed, it has been erroneously asserted by some authors to be venemous."
The Homalopsidæ are an extensive family of Snakes, of thoroughly aquatic habits, which are only occasionally found on the margins of rivers; several of them enter the sea, and in some parts of their organization they approximate to the true marine Snakes. They may be easily recognised by the position of the nostrils on the top of the snout, which enables them to breathe by raising only a very small portion of the head out of the water; an arrangement which is likewise seen in the Hippopotamus, the Crocodile, the Sea Snakes, and other aquatic animals. Many of them have a distinctly prehensile tail, by means of which they hold on to projecting objects. Their food consists either entirely of Fishes, or, in some species, of Crustaceans also. All appear to be viviparous, and the act of parturition is performed in the water. Not any of them attain a large size-about three or four feet in length, or considerably less; and in captivity they refuse to feed. All the Asiatic species of this family have a grooved fang at the hinder extremity of the maxillary bone. The species are numerous, and are arranged into many generic divisions. The majority are from the grand Indian region, extending to China and to Australia, but there are also several from the New World. The Herpeton tentaculatum, of Siam, is very remarkable from its snout terminating in two flexible, cylindrical, scaly tubercles, which are supposed to be employed as organs of touch under water—perhaps to discern its food, which as yet has not been ascertained. The largest known example of this curious Snake is only twenty-five inches long, of which the tail measures six inches.
We now proceed to the first family of Poisonous Snakes, that of
Which are very distinct from all that follow, though less so from certain of the harmless species appertaining to the two families last treated of. Some of their distinctions have been already noticed (p. 45), but they are especially characterised by their highly compressed tail, indicative of their thoroughly aquatic habits. According to Dr. Günther, there is no other group of 69 Reptiles the species of which are so little known, and the synonymy of which is so much confused, as that of the Sea Snakes. Most naturalists who have worked at them have been misled by the idea that the species were not nearly so numerous as they actually are. Mr. W. Theobald makes out as many as twenty-five inhabiting the Bay of Bengal and the adjacent seas, to which area this group of Reptiles is mainly confined, a few species extending to northern Australia, and one, the most emphatically pelagic, the Pelamis bicolor, even to the Pacific Ocean. One genus only, Platurus, approaches the Land Snakes in several of its characters; having much the physiognomy of an Elaps, with the cleft of the mouth not turned upwards behind, as in other Sea Snakes; the eye also is rather small, nor is the tail at all prehensile. There are two species of this particular form, one of which, P. scutatus, is rather common, and its geographic range extends from the Bay of Bengal and the China seas to the coasts of New Zealand; the distribution of the other, P. Fischeri, being nearly as extensive. The great genus Hydrophis has the posterior part of the body highly compressed, and most of the species are more or less of a bluish lead-colour, like that of the sea, or black, banded with white or yellowish white. They are so abundant in the Indian seas that some of them are taken with every haul of a fishing-net, and they are helpless and seemingly blind when out of the water; the fishermen commonly seizing them, one after the other, by the nape and throwing them back into the sea. Some of them (Microcephalophis of Lesson) have the head very small and the neck exceedingly slender, while the compressed body is large and thick.
These are comprised under the one family, Elapidæ, all of which have an erect, immovable, grooved, or perforated fang in the fore-part of the maxillary bone. There is little in their external appearance to distinguish them from the harmless Colubrine Snakes, to which they are more nearly akin, in all but their poison-fangs, than they are to the Rattlesnakes and Vipers; yet some of the most poisonous of Ophidians appertain to this family, as exemplified by the well-known Cobras of the Indian region and 70 of Africa, and also by some of the worst Snakes that inhabit Australia. In the colony of Victoria alone as many as ten species of Snakes are known, one only of which, Morelia variegata, is harmless; and one only of them, the formidable Death-adder (Acanthopis antarctica), belongs to the sub-order of the Viperine Snakes. The rest are included among the Colubriform Venemous Snakes, and most of the accidents from poisonous Snakes in that colony are due to what is there known as the Carpet Snake, Hoplocephalus curtus, while the Snake that bears the same name in the adjacent colony of New South Wales is the innocuous Morelia spilotes, which is a small Serpent of the family of Pythonidæ. Of the total number of Snakes known in all Australia, by far the greater number are venemous, which is the reverse of what occurs elsewhere. Only about five species, however, are really dangerous throughout the great island-continent, for in many of them the poison is by no means virulent. Thus, of Diemansia psammophis, which sometimes exceeds four feet in length, Mr. Krefft remarks that "its bite does not cause any more irritation than the sting of a bee." Also, that "the bite of Hoplocephalus variegatus is not sufficiently strong to endanger the life of a man. I have been wounded by it several times," writes Mr. Krefft, "and experienced no bad symptoms beyond a slight headache; the spot where the fang entered turning blue to about the size of a shilling for a few days." Again, of Brachysoma diadema, "this very handsome little Snake is venemous, but never offers to bite, and may be handled with impunity." Far otherwise, however, is the venom of Hoplocephalus curtus, and also of some others. H. curtus is one of the worst Snakes of Australia, where it inhabits the more temperate parts of the country from east to west. Its bite is almost as deadly as that of the Indian Cobra, to which it is, indeed, considerably allied. "A good-sized Dog bitten became paralyzed within three minutes, and was dead in fifty minutes afterwards; a Goat died in thirty-five minutes; a Porcupine Ant-eater (Echidna hystrix) lived six hours; and a common Tortoise, an animal which will live a day with its head cut off, died in five hours after being bitten." The H. superbus replaces it in Tasmania.
The Cobras (Naja) are widely known, alike from the virulence of their poison, and for their remarkable dilatable disk or 71 "hood" on the nape, the ribs which support this hood being much elongated. Two species are commonly recognised, the Cobra di capella of Southern Asia (Naja tripudians), and the Asp (N. haje) of Africa; but there are marked local varieties of both species, and the N. sputatrix of the Malay countries should probably be recognised as a third species. Those of India, with Ceylon, have a mark like a pair of spectacles upon the hood, while those of Burmah and the neighbouring countries eastward have only an oval black spot upon it. In India the commonest colour of this formidable reptile is uniform brown, though many are of a pale yellowish straw colour, and there are others of every shade between that and black. It grows to a length of about five feet, seldom more. "Almost every writer on the natural productions of the East Indies," remarks Dr. Günther, "has contributed to the natural history of this Snake, which has been surrounded by such a number of fabulous stories, that their repetition and contradiction would fill a volume." It is very generally diffused over the Indian region, though, as Mr. Theobald notices, from its nocturnal habits it is less often seen than many harmless species. "This Snake is, I believe," he adds, "of inoffensive habits, unless irritated, but is, of course, a dangerous neighbour to have in a house.13 Not only in Burmah, where the respect for animal life is greatest, but in India also I have known a Cobra enticed or forced into an earthen jar, and then carried by two men across a river, or some distance from the village, and liberated. Dr. Günther remarks that, 'singularly enough, it has never been obtained in the valley of Nepâl.' This is very easily accounted for," continues Mr. Theobald, "since few would venture to kill a Cobra, even for scientific purposes, in the rigorously Hindu state of Nepâl. In British India, decent Hindus will not kill a Cobra; and if one has taken up his abode in a house, he is permitted to remain, or else carefully inveigled into an earthen-pot, and carried away as described. Of course only the orthodox Hindu is so careful to abstain from injuring the Cobra, and their reverential 72 feeling is now perhaps rather the exception than the rule, though probably as strong as ever in Nepâl." A fine example of the still more formidable gigantic Cobra (Hamadryas elaps), to be noticed presently, was obtained from an earthen pot which had floated out to sea.
The late Sir J. Emerson Tennent mentions that "the Cinghalese remark that if one Cobra be destroyed near a house, its companion is almost certain to be discovered immediately after—a popular belief which I had an opportunity of verifying on more than one occasion. Once, when a Snake of this description was killed in a bath of the Government House at Colombo, its mate was found in the same spot the day after; and again, at my own stables, a Cobra of five feet long having fallen into the well, which was too deep to permit its escape, its companion, of the same size, was found the same morning in an adjoining drain.14 On this occasion the Snake, which had been several hours in the well, swam with ease, raising its head and hood above water; and instances have repeatedly occurred of the Cobra di capella voluntarily taking considerable excursions by sea" (or by rivers, as the writer has personally witnessed).]
Cobras are much dreaded, for they instil the most subtle poison into their bites. Their manners are very singular. When at rest the neck of the animal is no larger in diameter than the head; but when under the influence of passion and irritation the neck swells at the same time that the animal raises the front part of his body vertically, holding this part straight and rigid as an iron bar. The lower part of the body rests upon the ground, and serves as a support to the upper part, which is movable and capable of locomotion. This faculty of dilating the neck is as striking a trait in the organization of the Cobras, as the rattle is in Crotalus. The ancient inhabitants of Egypt adored them; they attributed to their protection the preservation of grain, and allowed them to live in the midst of their cultivated fields. The Cobra is no longer an object of adoration in the East, but is held sacred by many people, and it serves in nearly every country of Asia as a very 73 74 curious spectacle; being the Serpent chiefly used by snake-charmers in these countries, terrible as it seems to us.
The action of the snake-charmer is as follows: he takes in his hand a root, the virtue of which is supposed to preserve him from the venemous effects of the bite of the Cobra. Drawing the reptile from the cage in which he keeps it confined, he irritates it by presenting a stick to it; the animal immediately erects the fore part of its body, swells its neck, opens its jaws, extends its forked tongue, its eyes glitter, and it begins to hiss. Then a sort of battle commences between the Serpent and the charmer; the latter, striking up a monotonous sort of song, opposes his closed fist to his enemy, sometimes using his right hand and sometimes his left. The animal fixes its eyes upon the fist which threatens it, follows all its movements, balances its head and body, and thus simulates a kind of dance. Other charmers obtain from the Cobra an alternating and cadenced movement of the neck by the help of sounds which are drawn 75 from a whistle or small flute. It is said that these mysterious jugglers are able, by some sympathetic action they possess, to plunge these dangerous enemies into a sort of lethargy and death-like rigidity, and to bring them at will out of this momentary torpor. It is certain, at any rate, that they handle these animals, whose bite is extremely dangerous, with considerable impunity, and without having in any way neutralized or intercepted the venom. It is supposed by some that these charmers take the precaution of exhausting the venom of the Cobra every day by forcing it to bite something several times before exhibiting it. It is also certain that they more frequently draw the poison fangs—a wound from which can kill in the course of two or three hours.
The Asp (Naja haje) has a less dilatable neck; it is of a greenish colour, and marked with brownish spots. It is smaller than the former; is found in the west and south of Africa; and is especially common in Egypt. It was said to have been this Reptile which caused the death of Cleopatra.
[The genus Hamadryas of Cantor (Ophiophagus of Günther) differs very little from the true Cobras, but has a less developed hood, and a single small tooth placed at some distance behind the fang. The only species, H. elaps, attains to thirteen feet in length, and is proportionately formidable, being much less timid and retiring in its habits than the Cobras of the genus Naja. It preys habitually on other Snakes, and seems to be more plentiful eastward of the Bay of Bengal than it is in India. In Burmah it is styled the Gnán, and Mr. Theobald tells us that its venom is fatal in a few minutes. "One of these Snakes," he adds, "was brought in alive, and a snake-charmer came up to display his command over the animal. At first (as I am told) the Snake seemed cowed by the authoritative 'Hah' of the man; but suddenly, through some carelessness on his part, the Snake struck him on the wrist. The poor fellow at once ran off home to get an antidote, but fell down before reaching his own door, and died in a few minutes. When at Tonghu," continues Mr. Theobald, "I heard a case of an Elephant being killed by one of these Snakes, which I have no reason for doubting. The Elephant was a fine powerful male, and was pulling down with his trunk some creepers 76 or boughs, when a large 'Gnán,' which was disturbed in the tree, struck the Elephant on the trunk between the eyes. The Elephant at once retreated, became faint, and died in about three hours." This terrible Snake would appear to be not uncommon in the Andaman Islands, and its range of distribution extends through the Malay countries to the Philippines and to New Guinea.
The genus Bungarus is so called from the vernacular appellation of Bungarum, which is applied to one of the species on the Coromandel coast. Some of them are very like Cobras without the hood, as the "Kerait" (B. cæruleus), which is a much-dreaded Snake in India, but the geographic range of which extends neither to the countries eastward nor to Ceylon. The Snakes of this genus have a row of broad hexagonal scales along the middle of the back. The Kerait grows to four feet and a half in length, and has the upper parts of a bluish or brownish black, either uniform or more generally marked with numerous narrow white cross-lines, which mostly radiate from a white vertebral spot. In its habits it resembles the Cobra, preying on small Mammalia, Lizards, Toads, and probably other Snakes occasionally. The "Raj-sámp" (literally Lord Snake) is a larger and thicker species than the Kerait, beautifully marked throughout with alternate broad rings of black and golden-yellow. This one is found almost generally throughout the Indian region, and would seem to prey entirely on other Snakes, especially of the Tropidonotus genus. It is of very sluggish habits, and frequents moist places and the vicinity of water. A species, or local variety (B. ceylonicus), takes its place in Ceylon, and there is also a kindred species (B. semifasciatus) in China and Formosa. According to Cantor, the Bungarums are capable of darting nearly the anterior half of the body. Their bite is very dangerous; but "the magnitude of the danger," remarks Dr. Günther, "depends, as in other venemous Snakes, on many circumstances—chiefly on the size and energy of the individual Snake and on the place of the wound. As the fangs of the Bungarums are comparatively short, the wound is always superficial, and can be easily excised and cauterised; also, experiments made on some of the lower animals show that the general effect on the whole system becomes visible only after a lapse of time."
Of poisonous Snakes akin to the Bungarums, there are the 77 Xenurelaps bungaroides, founded on a single specimen received from the Khásya hills (north of Sylhet); and the Megærophis flaviceps, which inhabits the Indo-Chinese and the Malayan countries, but not India. The latter attains to more than six feet in length, and when alive or fresh the head and neck are vivid blood-red, which soon fades to a pale buff hue in specimens immersed in spirit, and hence the faulty name of flaviceps. As many as seven genera—Glyphodon, with two ascertained species; Diemansia, with four; Hoplocephalus, with eight; Pseudechis, with one; Pseudo-naja, with one; Brachysoma, with three; and Vermicalla, with one—are peculiar to Australia with Tasmania, making twenty known species of Colubriform Venemous Snakes in that range of territory, where others doubtless remain to be discovered; and there is one described as Pseudo-elaps superciliaris, which is suspected to be a second species of Pseudo-naja. The Cyrtophis scutatus of South Africa is a sort of hoodless Cobra, without any small teeth behind its fangs. In America there is only the genus Elaps, with numerous species, which are mostly of small size, and in some instances are very brightly coloured, as one of the Coral Snakes15 of Brazil (E. corallinus), which is beautiful coral-red, with the body encircled by equidistant black rings. The genus Elaps in America is represented in Africa by Homorelaps, in the Indian region by Callophis, and in Australia by Vermicalla. In general, these are small and slender Snakes, too much so to be held in much dread. What Dr. Günther remarks of the species of Callophis will apply, as we believe, equally to the others:—"They appear to prefer hilly countries to the plains, live constantly on the ground, and are slow in their movements. In their habits, in their form, and in their powerless muscular organization, they show the greatest similarity to the Calamariæ; and this is why the Callophides feed almost entirely on the latter, the venemous Snake being able to overpower the non-venemous. Both of these genera have also the same geographical distribution; and Ceylon, where we do not find the Calamariæ, is not inhabited by a single Callophis. If we are allowed to judge from the number of individuals of both genera brought to Europe in collections, the Calamariæ are about twice as numerous as the Callophides." 78 Cantor, who had opportunities of observing them, states that they are generally seen lying motionless, with the body thrown into many irregular folds, but not coiled. Although they are diurnal, their sight, from the minuteness of the pupil, appears to be as defective as their sense of hearing, and they may be closely approached without apparently being aware of danger. He never observed them to strike voluntarily, even when provoked, and he had difficulty in making an adult C. gracilis bite a Fowl; although, of course, the venom of these Snakes is as virulent as that of a Viper, the animals used for the experiments having died in the course of from one to three hours after they had been wounded. Therefore the greatest caution should be observed in catching or handling these Snakes. The shortness of their fangs and the small quantity of their poisonous fluid, however, will always give a very fair chance of recovery if the proper remedies be applied, should an accident occur. Two or three species of this genus inhabit India, and the rest are found in the Indo-Chinese and Malayan countries, one of the most common of them (C. intestinalis) having likewise been received from the Philippines. The C. nigrescens of the mountains of southern India attain to four feet in length, but they are mostly about half of that size, or even smaller.
Lastly, we arrive at
Which have a long, perforated, erectile fang on the maxillary bone, which is extremely short and bears no other teeth. This is described in greater detail subsequently (pp. 93, 94). They are arranged under the two families Crotalidæ and Viperidæ.
The Crotalidæ, or Pit Vipers, have the body robust, the tail of moderate length, or rather short, sometimes prehensile; head broad, sub-triangular, frequently scaly above or imperfectly shielded; a deep pit on the side of the snout, between the eye and nostril; the eye of moderate size, with vertical pupil. They are viviparous. The Pit Vipers are found only in Asia and America; those of the New World surpassing the Asiatic species in size, and therefore they are much more dangerous. Some live in bushes, others 79 on the ground. A rudiment of the curious caudal appendage of the American Rattlesnakes is found as a simple spine-like scale in the Asiatic species, constituting the genus Halys.
Some have the head covered with scales, having small shields on the edge of the forehead and brows; the cheeks are scaly, and the tail ends in a spine. Of these, the American genus Craspedocephalus and the Asiatic genus Trimeresurus have the subcaudal plates two-rowed to the tip.
The genus Craspedocephalus comprises the terrible Fer-de-lance of certain islands in the West Indies, which occurs on the mainland of South America, where four other species are recognised—one of them being found as far north as Mexico.]
The Fer-de-lance (C. lanceolatus) is met with in Martinique, Santa Lucia, and in the little island of Boquin, near St. Vincent. It attains to a length of nearly six feet; its colour is not always yellow, sometimes it is greyish, and even marbled with brown; the 80 head, which is large, is remarkable for a triangular space, the three angles of which are occupied by the muzzle and the two eyes.
This space, raised at its front edge, represents the head of a lance, large at its base and slightly rounded at the summit. On each side of the upper jaw, one, sometimes two, and even three, fangs are visible; all of which the animal makes use of for the purpose of wounding and discharging his venom. Of the poison fangs of the Fer-de-lance, Professor Owen remarks, "that they (in common with the Rattlesnake and Viper) are coated with a thin layer of a sub-transparent and minutely cellular cement. This disposition of the dentinal tubes is obedient to the general law of verticality, and the external surface of the tooth can be exposed to no other pressure than that of the turgescent duct with which it is in contact." It feeds on Lizards and the smaller Mammals, especially Rats, but it is capable of killing large animals, such as Oxen. The Negroes working among the sugar-cane, and soldiers in the Martinique service, often become victims to the Fer-de-lance. This Snake is, unfortunately, very prolific, and its venom is so subtle, that animals stung by it die three hours, twelve hours, one day, or several after the accident; but their death is certain. The wound produces extreme pain, and is immediately followed by more or less livid swelling; the body becomes cold and insensible, the pulse and respiration become slower, the head becomes confused, coma appears, and the skin turns bluish; sometimes extreme thirst and spitting of blood are experienced, and paralysis attacks the whole system.
Another species is known in Brazil as the "Jararaca" (C. brasiliensis), and there is a third in the same country, the C. bilineatus; a fourth, C. elegans, is believed to be from the west coast of South America; and a fifth, C. atrox, inhabits from Demerara to Mexico. All of them are most highly formidable and dangerous Snakes, which are held in especial dread.
The ten or more species of Trimeresurus occupy their place in the woodland districts of tropical Asia and its islands. In them the hinder labial shields are the smallest. The head is triangular, covered above with small scales, except the foremost part of the snout and the superciliary region, which generally are shielded; 81 body with more or less distinctly keeled scales, in from seventeen to twenty-five series. Body and tail of moderate length, prehensile. These reptiles are more or less arboreal, as is indicated by their prehensile tail, and by their green or varied coloration. "In general," remarks Dr. Günther, "they are sluggish, not attempting to move out of the way, and as they very closely resemble the branch on which they rest, they are frequently not perceived until they prepare to dart, vibrating the tail, and uttering a faint hissing sound, or until they have struck the disturber of their rest. Accidents caused by them, therefore, are not of uncommon occurrence, and it is a fortunate circumstance that comparatively few of them attain to a size of more than two feet, so that the consequences of their bite are less to be dreaded than that of various other poisonous Snakes. Indeed, numerous cases are on record which show that the symptoms indicating a general effect on the system were of short duration, extending only over from two to forty-eight hours, and confined to vomiting, retching, and fever. After the pain and swelling of the bitten member or spot have subsided, the vicinity round the wound becomes discoloured, mortifies, and is finally thrown off as a black, circular slough, after which health is speedily restored. The bite of larger specimens, from two to three feet long, is more dangerous, and has occasionally proved fatal; so that the greatest care should always be observed in the immediate treatment of the patient. When roused, these Snakes are extremely fierce, striking at everything within their reach; and Cantor states that in the extreme of fury they will fix their fangs in their own bodies. Frogs, small mammalia, and birds form their food, and I have never found a Lizard or Snake in their stomach."
Three or more of the species inhabiting India and Burmah are of a beautiful leaf-green colour, which changes to dull blue after long immersion in spirit. The commonest of them, T. carinatus, varies remarkably in colouring, however, in the Andaman and Nicobar Islands; if, indeed, the species be quite the same. These grow to over three feet in length, of which size they are sufficiently formidable. The kindred genus, Peltopelor, is founded on a single species inhabiting the mountains of Southern India, P. macrolepis, which is remarkable for the very large scales with which its head 82 and body are covered. Lachesis, with two species, is another kindred genus in South America, in which the end of the tail has four rows of scales underneath. The Calloselasma rhodostoma is a very formidable reptile of this same series, which inhabits the Malay countries. It has a remarkably broad head, and grows to three feet or more in length. Dr. Günther states that "it is one of the most beautiful and most dangerous of venemous Snakes. Feeding on frogs, it frequents grassy plains, and approaches gardens and human dwellings. Kuhl was eye-witness to a case where two Men, bitten by one and the same Snake, expired five minutes after." Another Malayan species is known as the Atropos acouba. The genus Halomys is characteristic of the fauna of Central Asia, the species being found in Tartary, on the northern side of the Himalayas, in China, in Japan, and in Formosa. One of them occurs in the Western Himalaya, at an altitude of 9,000 feet, and another has been referred to this genus from the mountains of Southern India. The "carawalla" of Ceylon (Hypnale nepa) is likewise found on the mountains of Southern India. It is a small species, but a good deal dreaded, although, remarks Dr. Günther, "its bite is but exceptionally fatal to Man, and in such cases death does not occur before the lapse of some days. There is always every hope of restoring the patient by a timely application of the proper remedies." Its crown is more shielded than is usual with Snakes of this family, and it varies much in colouring.
The rest of the Crotalidæ are American, and consist of the famous Rattlesnakes and their immediate kindred. In the genus Cenchris the tail ends with a spine, and the tip of the tail has several rows of scales beneath. The well-known "Copperhead" (C. contortrix) belongs to this genus, and the black "Water Viper" (C. piscivorus). The last has bred repeatedly in the London Zoological Gardens, and is rather a large species, of very aquatic propensities. "The Copperhead," according to Dekay, "is a vicious reptile, and its venom is justly dreaded, being considered as deadly as that of the Rattlesnake; and an instance is recorded in which a Horse, struck by one of these reptiles, died in a few hours. Its motions are sluggish, and when approached it assumes a threatening aspect, raising its head and darting out its tongue. It chiefly occurs in pastures and low meadow grounds, feeding on 83 Field-mice, Frogs, and the smaller disabled birds." The poison of the black Water Viper is equally to be dreaded.
The true Rattlesnakes have the tail furnished with the extraordinary appendages at its tip which will be described presently. According to differences in the shields and scales covering the head, Dr. Gray arranged them into three genera—Crotalophorus, with three species; Uropsophus, with one; and Crotalus also with one, C. horridus, which appears to be the only one known in South America. Of the common Northern Rattlesnake (Uropsophus durissus), Dekay remarks that, "although furnished with such deadly weapons, the Rattlesnake can scarcely be termed a vicious animal, for he rarely strikes unless almost trodden upon. When suddenly disturbed, he throws himself into a coil, and warns the aggressor by rapidly vibrating his rattles, which, however, can scarcely be heard beyond the distance of a few yards. This is most usually the case, but they occasionally strike without the slightest warning. At the moment the Snake strikes, he ejects the venom forcibly into the wound. In an instance of a very large Rattlesnake from Florida (C. horridus), which was irritated, he struck violently against the iron wire on the side of the cage, and spurted the venom to the distance of three feet."16 The fibulæ, or rattles, seldom exceed fifteen in number, and are rarely so many.]
The common Northern Rattlesnake sometimes attains to six feet in length, the middle being about the size of a man's leg; the colour of the back is grey, mixed with yellow. Upon this foundation extends a longitudinal row of black spots, bordered with white; towards the muzzle the flat head is covered with six scales larger than the others, and disposed in three transverse rows, each formed of two scales. The males are smaller, much more brightly and less darkly coloured than the other sex. The very long and visible fangs are situated in front of the upper jaw. The scales on the back are oval, and raised in the middle by a bone which extends in the direction of their greatest diameter. The underpart of the body is furnished with a single row of large plates. The Rattlesnake owes its name to a remarkable peculiarity in its structure; the extremity of the tail is furnished with small horny cells, 84 articulated one into the other. When the animal advances these little capsules resound slightly, like the dry husks of beans which still retain their seeds, thus giving notice of the approach of this terrible enemy. The sibilant rattle of these appendages is not very loud, but it may be heard about thirty paces off, and announces the approach of the reptile while it is still at that distance.
Rattlesnakes feed on small mammals and upon other reptiles, waiting patiently for their approach; when close to them, the Rattlesnake throws itself upon them. They are oviparous; and for some time after they are hatched, the young are said to seek a refuge in the mouth of their mother. During summer Rattlesnakes remain in the midst of stony mountains, uncultivated places, or places covered with wild wood; they generally choose those parts most exposed to the heat,—the sunny shores of a fountain or stream where small animals come to drink. They like also to place themselves under the shadow of an old fallen tree. Audubon, the celebrated ornithologist, says that he has often met with Rattlesnakes rolled up in a 85 state of torpor when the temperature was low. Rattlesnakes are revered by some of the American natives, who know how to lure them from their houses without killing them; for it is a singular fact that this terrible animal is not insensible to the sound of music. Chateaubriand's remarks will be read with interest: "In the month of July, 1791," says this celebrated writer, "we were travelling in Upper Canada with some savage families of the Ounoutagnes. One day, when we had stopped in a plain on the banks of the river Genedie, a Rattlesnake entered our camp. We had a Canadian amongst us who played on the flute; wishing to amuse us, he approached the animal with this new kind of weapon. At the approach of his enemy, the splendid reptile at once coiled itself up spirally, flattened its head, puffed out its cheeks, contracted its ears, and showed its envenomed fangs, while its forked tongue moved rapidly, and its eyes burned like red-hot coals; its body became inflated with rage, rose and fell like a pair of bellows; its dilated skin bristled with scales; and its tail, which produced a sinister sound, oscillated with lightning rapidity. The Canadian now began to play upon his flute. The Snake made a movement expressive of surprise, gradually drew its head backwards, closed its inflamed mouth, and, as the musical sounds struck it, the eyes lost their sharpness, the vibration of its tail relaxed, and the noise which it made became weaker, and finally died away altogether; the coiled-up line became less perpendicular, the orbs of the changed Snake opened, and in their turn rested in wider concentric circles on the ground. The scales of the skin were also lowered, and immediately recovered their wonted brilliancy, and, turning its head slowly towards the musician, it remained immovable in an attitude of pleased attention. At this moment the Canadian walked away a few steps, drawing low and monotonous tones from his flute; the reptile lowered his neck, opened a way among the fine grass with its head, and crawled in the steps of the musician who thus fascinated him, stopping when he stopped and following him when he began to move away. The Snake was thus conducted from our camp in the midst of a throng of spectators—as many Red-skins as Europeans—who could hardly believe their eyes."
It is generally agreed that Rattlesnakes only attack Men in self-defence, 86 but it is at all times a dangerous neighbour, and it is important to know how to keep them at a distance in countries where they abound. The Pig is an excellent auxiliary in obtaining this result. In the west and south of America, when a field or farm is infested by these ferocious reptiles, it is usual to put a Sow with its young brood there, and the Snakes, it is said, will soon be eaten up. It appears that owing to the fatty matter which envelopes the body of this animal, it is safe from the venemous bite. Besides, it likes the flesh of the Snakes, and eagerly pursues them. According to Dr. Franklin, when a Pig sees a Rattlesnake, it smacks its jaws, and its hairs bristle up; the Snake coils itself up to strike his enemy; the Pig approaches fearlessly, and receives the blow in the fold of fat which hangs upon the side of its jaw. Then he places a foot on the tail of the Snake, and with his teeth he begins to pull the flesh of his enemy to pieces, and eats it with evident enjoyment.17 The Pig is not the only animal employed to destroy Rattlesnakes. Dr. Rufz de Lavison, who has long resided in the French Antilles, and who has since been manager of the Jardin d'Acclimatation, of Paris, has published a highly interesting work, in which he relates the very important services which certain birds, especially the Secretary-bird, or Serpent-eater (imported from South Africa), render by destroying Rattlesnakes in the West Indies. We have said that the Crotalidæ are some of the most dangerous of any Snakes; let us mention some facts which show the frightful power of their venom. A Crotalus, about three feet in length, killed a Dog in about fifteen minutes, a second in two hours, and a third in about four hours. Four days after he bit another Dog, which only survived thirty seconds; and another, which only struggled four minutes. Three days afterwards it bit a Frog, which died at the end of two seconds; and a Chicken, which perished at the end of eight minutes.
An American, named Drake, arrived at Rouen with three live Rattlesnakes. In spite of the care which he had taken to preserve them from cold, one of them died. He put the cage which contained 87 the other two near to a stove, and excited them with a small stick, to assure himself that they were alive and in health. As one of the Snakes made no movement, Drake took it by the head and tail and approached a window to see if it was dead; the animal turned its head quickly, and bit the unfortunate man on the back of his left hand; as he replaced it in the cage he was bitten anew in the palm of the same hand. "A doctor! a doctor!" cried the unhappy man. He rubbed his hand upon some ice which was close by, and two minutes after, he bound the wrist tightly with a cord. Four hours later a doctor arrived, and cauterized the wound, but alarming symptoms soon appeared. Syncope, noisy respiration, scarcely any pulsation, and involuntary evacuations followed; the eyes closed, their pupils contracted; the limbs became paralyzed, and the body cold. Drake died at the end of nine hours.
Some experiments made by a friend of Dr. Bell seem to present different results. This gentleman had received a living Rattlesnake from America, intending to try the successive effects of its bite upon some Rats. He introduced one into the cage with the Snake: it immediately struck the Rat, and the latter died in two minutes. Another that was placed in the cage ran to the farthest corner, uttering cries of distress. The Snake did not attack it immediately; but after about half an hour, on being irritated, it struck the Rat, which, however, exhibited no signs of being poisoned for several minutes; nor did it die for about twenty minutes after the bite had been inflicted. A third Rat, remarkably large, was then introduced into the cage, and exhibited no signs of terror, nor did it seem to be noticed by its dangerous companion: after watching some time, the gentleman retired to bed, leaving the Rattlesnake and Rat in the cage together. In the morning the Snake lay dead, and the Rat had supped on the muscular part of its backbone. Unfortunately, Dr. Bell does not remember at what season this experiment took place, but thinks it was not in very warm weather.
The climate of France differing only slightly from that of the United States, it is consequently well adapted for the production of Rattlesnakes. If a living male and female of these dangerous Crotalidæ were to escape from a menagerie, they would soon 88 infest the country with their terrible progeny. It is for this decisive reason that public exhibitions of Rattlesnakes are forbidden in France. Nevertheless, two or three may be seen in the collection of the Museum of Natural History at Paris, miserably installed in a chest, which is quite unworthy of this establishment. The Rattlesnakes are enclosed in a double cage, and every measure of precaution is taken which prudence demands.
It is a remarkable fact that the poison is secreted after death. Dr. Bell, in his "History of British Reptiles," adduces the following as evidence of the facts:—He was dissecting very carefully and minutely the poison apparatus of a large Rattlesnake, which had been dead some hours; the head had been taken off immediately after death; yet, as Dr. Bell continued his dissection, the poison continued to be secreted so fast as to require to be dried up occasionally with a sponge or rag: and his belief is, that there could not be less than six or eight drops of the poison. It is obvious that such experiments require the utmost caution, seeing that preparations are not without danger.
[The family of the Viperidæ, or true Vipers, are peculiar to the Old World, inclusive of Australia, with the sole known exception of one species in Peru. They have generally a robust body, with non-prehensile tail; the head broad or thick, generally scaly above or incompletely shielded; the eye of moderate size, with vertical pupil, and they are at once distinguished from the Crotalidæ by the absence of the pit below the eye. The scales are keeled except in one genus (Acanthopis). For the most part, these reptiles inhabit exposed and arid situations, though perhaps all of them will take to the water on occasions, as does the common British Adder.
They are divided, firstly, into those which have a depressed head, rounded on the sides, and covered with acutely-keeled scales. Some of these have large nostrils in the centre of a ring-like shield, edged with a large scale above. Such are the genera Daboia in the warmer parts of Asia, and Clotho, which is peculiar to Africa—both genera are terrifically venemous.
The famous Tic-polonga of Ceylon (Daboia elegans) is also widely diffused over India and Burmah. It is beautifully marked with three rows of white-edged, oblong, brown spots. Occasionally 89 the spots forming the middle row are connected like the beads of a necklace, whence the name Cobra monil (literally Coluber moniliger), applied to the young of this Viper by the Indo-Portuguese, and now corrupted into "Cobra de Manilla," which bears the reputation of being a highly poisonous Snake of diminutive size; it attains, however, to a length of nearly five feet, the tail then measuring about eight inches, with considerable thickness of body. It is nocturnal, and preys chiefly on Mice. In Burmah this formidable Viper is dreaded almost as much as the Hamadryas. It has been obtained in the Himalayas at an elevation of 5,500 feet, at Almorah, and elsewhere. Mr. Theobald has known one to kill a Bull-terrier in twenty minutes. The D. xanthina is a second species of this form inhabiting Asia Minor.
The genus Clotho consists of the terrible Puff-adders of Africa, of which there are at least four or five species. Among the best known of them are the ordinary Puff-adder (C. arietans), and the Berg-adder (C. atropos), of the Cape colonists. The Rhinoceros Puff-adder, C. nasicornis, of Guinea, has the scales over the nostrils of the male produced into a long recurved spine; and in the Horned Puff-adder, C. cornuta, of South Africa, there is a group of small horn-like scales over each eye. Examples of the Common and of the Rhinoceros Puff-adders may generally be seen in the reptile house of the London Zoological Gardens. The last mentioned is a huge Viper of wondrous beauty, both of colouring and in the complex pattern of its markings, especially 90 as seen when it has newly shed its epidermis; but the aspect of its surprisingly broad, flat, and triangular-shaped head unmistakably betokens its terrific powers. Its head is remarkably massive. One peculiarity of the Puff-adders is that they sometimes hold on to their victim by their long fangs. Thus, of the common C. arietans Sir A. Smith remarks that "although generally inactive, it is by no means so when attacked—its movements are then bold and energetic, and when once it seizes the obnoxious object, it retains its hold with great determination, and some considerable exertion is often necessary to detach it."18 The traveller Burchell remarks of this Snake that "its venom is said to be most fatal, taking effect so rapidly as to leave the person who has the misfortune to be bitten no chance of saving his life, but by instantly cutting out the flesh surrounding the wound. Although I have often met with this Snake," he adds, "yet, happily, no opportunity occurred of witnessing the effects of its poison; but, from the universal dread in which it is held, I have no doubt of its being one of the most venemous species of Southern Africa. There is a peculiarity which renders it more dangerous, and which ought to be known to every person liable to fall in with it. Unlike the generality of Snakes, which make a spring or dart forward when irritated, the Puff-adder, it is said, throws itself backwards, so that those who should be ignorant of this fact would place themselves in the very direction of death, while imagining that by so doing they were escaping the danger. The natives, by keeping always in front, are enabled 91 to destroy it without much risk. The Snakes of South Africa, as of Europe, lie concealed in their holes in a torpid state during the colder part of the year. It is, therefore, only in the hottest summer months that the traveller is exposed to the danger of being bitten." Dr. Gray refers doubtfully to this genus both the Echidna inornata of Sir A. Smith, and the E. mauritanica of Duméril and Bibron, from Algeria; likewise a Peruvian species named Echidna ocellata by Tschudi, which is the only known instance of a member of this family inhabiting the New World. The appellation Echidna, however, belongs properly to the Porcupine Ant-eaters of the class Mammalia.
The species of Cerastes and of Echis have the nostrils much smaller than the preceding, and are Vipers of less formidable size. In the two species of Cerastes, or Horned Viper, the eyebrows of the male bear commonly a sort of horn. C. Hasselquistii is common in Egypt, and the other, C. Richii, inhabits Tripoli. Of Echis there is one species in Egypt and North Africa—E. arenicola, and another in India—E. carinata. The latter grows to about twenty inches long, of which the tail measures two inches and a third. These Vipers commonly lie half-buried in the sand, which they much resemble in colour. They feed upon Centipedes (Scolopendra), and no case is known of their bite having proved fatal.
The remaining Viperidæ have the head more or less shielded. They are divided by Dr. Gray into Vipera (with two European species, not found in Britain—V. aspis from the Alps, and V. ammodytes from the countries bordering on the Mediterranean);—Pelias, which contains only the Common British Adder, P. berus; Sepedon, with one species only, from South Africa, S. hæmachates; Causus, with also only one African species, C. rhombeatus; and finally, Acanthopis, founded on the Death-adder of the Australian colonists, A. antarctica, which is the only member of the family Viperidæ known to inhabit Australia, where the Poisonous Colubrine Snakes are so numerous. It is also the only known species the scales of which are smooth or not keeled. It seldom exceeds thirty inches in length, and varies a good deal in colour. Like other Viperidæ it is sluggish in its movements, but when irritated it flattens itself out generally in the form of the letter S, 92 turning round to one side or the other with astonishing rapidity, but never jumping at its enemy or throwing itself backward, as the Puff-adders are described to do. The Death-adder is found in almost every part of Australia northward of the thirty-sixth parallel of south latitude.]
The Common Adder (Pelias berus), is not improbably the Εχις of Aristotle, and the Vipera of Virgil, as it is the Manasso of the Italians, the Adder of the country-people in England and Scotland, and the Vipère of France. It is found in all these countries, and in Europe generally.
The Common Adder varies in length, from thirteen or fourteen inches to double that length; and from two to three or even four inches in girth.
Its general colour varies considerably: in some it is olive, in others reddish-brown, varying sometimes to an ashy-grey; at other times it is greyish-black. A waving brown or blackish line runs along the back. A row of unequal spots of the same colour is observable on the flanks; the belly is slate-coloured; the head nearly triangular, a little larger than the neck, obtuse and truncated in front, and covered with granulated scales. Six small plates cover the muzzle, two of which are perforated for the nostrils, which are lateral, forming a blackish spot. Above is a sort of V shape, formed by two black bands. The upper jaw is a 93 white ground, spotted with black; the lower jaw is yellow. The eyes are small and sharp, edged with black. The tongue is long, grey, and forked.
Adders are met with in the wooded, stony, and mountainous regions of southern and temperate Europe—in France, Italy, England, Germany, Prussia, Sweden, Poland, and even Norway. They are met with in the heaths near London and in the neighbourhood of Paris; they are met with at Montmorency, and in the forest of Fontainebleau. They feed upon Lizards, Frogs, mollusks, worms, insects, and small mammalia, such as Field-mice, Shrews, and Moles. They pass the winter and early spring in a state of torpor in deep hollows, where they are sheltered from the cold. It is not unusual to find several Adders coiled up together in one heap, entwined and intimately interlaced together.
The movement of Adders is abrupt, slow, and irregular. They appear to be shy and timid creatures, shunning the day, and only seeking their food in the evening. The young come into the world naked and living: so long as they are maintained within the mother, they are enclosed in eggs with membranous shells. Soon after their birth the young Vipers, whose length does not exceed six or seven inches, are abandoned by the mother, and left to shift for themselves. They do not, however, acquire their full development till they are six or seven years old. Adders are justly considered objects of fear and horror both to Men and to other animals. They carry with them a formidable apparatus, of which it is important that both the structure and the mode of action should be known. This venemous apparatus is composed of three parts—the secreting glands, the canal, and the hooked fangs.
The gland is the organ which secretes the venom; it is situated upon the sides of the head, behind and a little beneath the globe of the eye; it is formed of a number of inflated bladders, composed of a granulous tissue, and disposed with great regularity along the excretory canal, not unlike the barbs of a pen-feather. This arrangement, however, is only visible through a microscope. The tube destined to conduct the secreted venom through the gland is straight and cylindrical; after being filled, in its short journey it ends in two peculiar hook-like teeth, called fangs, tapering to a point, and in shape horn-like. They 94 are much longer than the others, and placed one to the right, the other to the left of the upper jaw. The Adder, then, is furnished with two of these poison-fangs; they are curved and sharp-pointed, convex anteriorly, and furnished with a straight duct which commences in one part by a slit placed at the anterior part of its base, terminating by a second and smaller cleft towards its point, and on the same side. This last cleft is like a little trench or fine furrow, which extends the whole length of the convexity. These hooked teeth are surrounded by a fold of the gums, which receives and partly hides them, like a sheath, when they are at rest or hidden. They are attached to the upper maxillary bones, which are small and very mobile, and are put in motion by two muscles. Behind them are dental germs, intended to replace them when they fall out. The other teeth in the roof of the mouth belong to the palate, where they form two rows.
Such are the terrible weapons of the Viper group. It is not, therefore, as many persons still believe, with the tongue that the Adder inflicts its wound; the forked, projecting tongue serves them as a feeler, and to drink with, but cannot inflict a wound. We have said that when in a state of repose the hooked teeth are hidden; when the animal wishes to use them, they issue from their fleshy sheath, somewhat in the same manner as a man draws his knife, when attacked, to defend himself, and in this case the knife is poisoned.
Adders use their fangs to seize the small animals which serve as their prey. They do not voluntarily attack a Man; on the contrary, they flee at his approach. But if he imprudently places his foot on or attempts to seize them, they defend themselves vigorously. Let us see how an Adder conducts itself when it hunts its prey and takes it. In this case it may be supposed to act without passion, merely seizing its prey for food; it simply bites, sinking its fangs into the body of its victim. In proportion 95 as the fangs penetrate the body of the animal the poison flows into the canal, which again conducts it to the fangs under the influence of the contracting muscles, by which they are raised and made to press upon the gland; but this movement causes the Adder to close its mouth, and the venom is injected into the wound.
Adders bite in much the same manner when seized by the tail or middle of the body; but when they think themselves attacked and become irritated, they strike rather than bite. At first they coil themselves up into several superposed circles, then they will uncoil themselves to their whole length with excessive quickness, extending their bodies like a spring, drawing it out with the rapidity of lightning, and gliding over a space equal to their own length; for they never leave the ground. They will now open their jaws wide, erect their fangs, and strike, first throwing back their heads, by which means they contrive to strike as with a hammer.
Dr. Bell expresses doubts, in his "History of British Reptiles," of the existence of any well-authenticated case in this country of an Adder bite terminating fatally.19 At the same time he cautions all persons against exposure to them in the heat of summer and autumn, when the poison is most virulent. The remedy applied to such a bite is to rub the part with olive oil, over a chafing dish of coals, and to take a strong dose of ammonia (spirit of hartshorn) internally.
Open copses, dry heaths, new woodland clearings, and sandy wastes are the usual haunts of the Adder; and in such places its hibernaculum is usually found in winter, where several of the same species lie intertwined in a torpid state.
It was long supposed that Adders, and Snakes generally, exercise a sort of magnetic action from a distance—a power which has been called fascination. This impression has been denied, and attributed, not without reason, to a less mysterious cause; namely, the sentiment of profound terror which these creatures inspire. This terror manifests itself in animals by tremblings, spasms, and convulsions. The sight of a venemous Snake sometimes renders its victims immovable, incapable of flight, and as it 96 were paralyzed, and they allow themselves to be seized without opposing the slightest resistance. Others give themselves over to confused movements, which, far from saving them, only make their capture easier. M. Duméril, while pursuing experiments in the Museum of Natural History, demonstrative of the sudden and mortal action of the bite of a Viper on little birds, saw a Goldfinch, which he held in his hands, die suddenly, merely at the sight of the Viper.
In warm countries, wounds produced by the larger species of these terrible reptiles are extremely dangerous—they swell, become red and ecchymose, and sometimes livid; the wounded person is seized with syncope, fever, and a series of morbid symptoms, which often terminate in death. The remedy is to bind immediately a ligature above the wound with a band, such as a rolled handkerchief, a cord, or a string, so as to stop all communication of the blood with the rest of the body, and thus prevent the absorption of the venom into the system till more effectual means can be adopted. It is well to suck the wound and make it bleed; it is necessary also to make an incision, so as to expose the internal parts, and then to cauterize the wound immediately, either with a red-hot iron or by means of a caustic agent. For this purpose the following composition may be employed:—
Perchloride of iron | 60 | grains. |
Citric acid | 60 | " |
Hydrochloric acid | 60 | " |
Water | 144 | " |
A few drops of this is poured on the wounded part, which is then covered with a small piece of lint. Iodine or iodinet of potassium can also be employed. M. Viand-Marais has substituted the following composition for this compound with great success:—
Water | 50 | grains. |
Iodinet of Potassium | 50 | " |
Metallic iodine | 50 | " |
To facilitate the introduction of caustic into the wound, the same naturalist has invented a little bottle closed with emery; the stopper, which is long, and conical at the lower end, plunges 97 into the liquid. By means of this stopper the medicated substance can be made to penetrate by drops as far as the bottom of the wound, which has been previously enlarged by the bistoury. This little apparatus will replace with advantage the bottle of volatile alkali with which Viper-hunters are usually furnished. But all these means are only useful when applied immediately. The limbs and round about the wound must besides be rubbed with ammoniacal liniments. Afterwards emollient poultices should be used to lower the swelling and reduce the chances of congestion; while tonics, sudorifics, and sometimes ammoniacal potions should be given internally.
It is a remarkable fact that this venom, which is one of the most virulent poisons known, can yet be swallowed with impunity. It is neither acrid nor burning, and only produces a sensation on the tongue analogous to that caused by greasy matter. But if introduced into a wound in sufficient quantities, it enters into the blood, and causes death with frightful rapidity. This is a characteristic common to all morbid and venemous virus.
The strength of the venom varies according to the species of Snake, and likewise the condition of the animal. The same species is more dangerous in hot than in cold or temperate regions. The bite is serious, according as the poison is more or less abundant in the glands, and probably with the degree of rage experienced by the animal, as Professor Owen supposes.
[Of Snakes in general it has been remarked that "all strangers in countries where these reptiles abound are apt to exaggerate their danger; but in a year or two they think as little of them as we do in England. I never knew an instance of a Snake attacking a person unless it was trodden upon or molested, and even then they almost always give warning by hissing, or endeavour to effect their escape. During my residence in the Cape colony, I have at different times trodden on them or kicked them in the grass unintentionally, but was never bitten."20 This writer, however, could hardly have accidentally placed his foot upon a Puff-adder.21]

This is the second order of the great section of Scaly Reptiles (Squamata), as distinguished from the Shielded Reptiles (Cataphracta). The name Saurian, Σαυρος, given by Aristotle to the genus of Lizards, has been more comprehensively applied to a group of Reptiles which have the body elongated, covered with scales, or having the skin rough like shagreen. They have, for the most part, four feet, the toes of which are furnished with hooked claws; their eyelids are movable, and their jaws armed with encased teeth; they have a distinct tympanum, a heart with two auricles and a single ventricle, sometimes partially valved, having sides and a sternum. They are not subject to metamorphosis, and, finally, they are furnished with a tail.
["By far the greater number of the Saurians," writes Dr. Günther, "are easily distinguished from the other orders of reptiles by their elongated form, by their movable thorax covered with skin, by the presence of legs, and by their general integuments, which are either folded into scales, or granular, or tubercular, or shielded; still, there are many Saurians which, at a superficial glance, might easily be taken for members of the preceding order—that of the Snakes; and it cannot be denied that there is a gradual transition from one of these orders to the other. On the part of the Saurians, we allude to those which have no externally visible limbs, and which combine with a greatly elongate, cylindrical body, the peculiar kind of locomotion we observe in Snakes. Yet the greater affinity of these reptiles to the ordinary Lizards is indicated by another character, which is in intimate connection with their mode of life. The 99 Snakes, having movable maxillary bones, and mandibles not joined by a symphidis, are enabled to swallow other animals of apparently greater bulk than their own. In the Saurians the maxillæ are fixed and immovable, and the mandibles are joined by an osseous suture, so that the cleft of the mouth can be dilated only in the usual vertical direction. Moreover, in these limbless Saurians we always find bones of the shoulder hidden below the skin, whilst no trace of them can be discovered in the true Snakes. The motions of some Lizards are extremely slow, while those of others are executed, with very great, but not lasting, rapidity. Many of them have the power of changing their colours, which depends on the presence of several layers of cells loaded with different pigments; these layers the animal compresses by more or less inflating its lungs, whereby the changes in the coloration are effected."
Dr. Günther does not follow Dr. Gray in arranging all true reptiles into the two grand divisions of Shielded Reptiles (Cataphracta) and Scaly Reptiles (Squamata), but he includes the Crocodilidæ among the Saurians as a first grand division of them—Emydosauri, and the other Lizards constitute his second grand division of them—Lacertini. These latter are again primarily divisible according to the structure of the tongue. Thus, in the series of Leptoglossa, the tongue is elongate, forked, and exsertile, much as in the Ophidians; in that of Pachyglossa the tongue is short, thick, attached to the gullet, and is not exsertile; and in the Vermilingues it is Worm-like, club-shaped in front, and very exsertile.
The various genera of Saurians which have either not a trace of external limbs, or have them more or less diminutive and rudimentary—either the usual two pairs or one pair only, and in the latter case sometimes the fore and sometimes the hind pair being deficient—are included among the Leptoglossa, or the series which have a forked and protrusile tongue; and, so far as is practicable, we will commence by noticing the different serpentiform genera; only, in a classification which is not confessedly superficial, it will be found that the various Snake-like Saurians appertain to several distinct natural families, most of the other genera belonging to which have, in sundry cases, limbs that are well developed. 100 Some of them, therefore, will have to be noticed as the different families to which they belong are successively treated of; and there will yet remain the curious serpentiform family of Amphisbænidæ, which Dr. Gray refers to his grand series of Shielded Reptiles (Cataphracta).
The same naturalist divides the Leptoglossa into two tribes, which he styles Geissosaura and Cyclosaura; and, as constituting particular division of the former, he includes under it the family Typhlopidæ, which Dr. Günther refers—as we have seen—to the order of Ophidians. In the series of Geissosaura, the scales of the belly and (almost always) of the back and sides are quincuncial, rounded, and imbricate; the tongue is narrow, short, flat, and but slightly forked; and the head is of a conical shape, and is covered with regular shields.
Of the families thus characterised, some only have distinct eyelids, as the families Acontiadæ, Ophiomoridæ, Sepsidæ, and Scincidæ; while others have the eyelids rudimentary and the eyes exposed, as the families Lialisidæ, Aprasiadæ, Pygopodidæ, and Gymnopthalmidæ. In the Acontiadæ the nostrils are placed in the enlarged rostral plate, with a longitudinal slit behind. The form of the body much resembles that of our common Orvet, or Blind-worm, and their limbs, when present, are so rudimentary that they can aid little in locomotion. One genus, Acontias, is without limbs, and the eyes are furnished with a lower lid, while the upper eyelid is rudimentary. Of this, one species, A. meleagris, inhabits South Africa; and another, A. Layardii, has been discovered in Ceylon. The genus Nessia has four rudimentary limbs, and the rostral shield is large, sub-conical, and depressed. In one species, N. monodactyla, the limbs are diminutive, the posterior placed far apart from the anterior, all being very short, weak, and undivided into toes. In another, N. Burtoni, each foot is divided into three minute toes. Both species are peculiar (so far as known) to Ceylon, and the habits of this family are much the same as those of our common Orvet (Anguis fragilis).
The family of Ophiomoridæ is founded on a single genus and species, Ophiomorus miliaris, which inhabits North Africa. As remarked by Dr. Gray, this reptile seems to be intermediate to the Acontiadæ and the Scincidæ, and makes it appear as if the large 101 rostral shield of the former was formed of the united rostral, supra-nasal, and nasal shields of the present family, and of the Scincidæ. It has an elongate, cylindrical body, without external limbs, and the ears are hidden under the skin; the eyes are distinct, with valvular eyelid; and the scales of the body and somewhat elongate tail are hexagonal.
The Sepsidæ differ from the preceding, and also from the great family of the Scincidæ, by having the nostrils placed in the front edge of a small shield, in a notch at the hinder side of the rostral plate, which latter is rather large and square. The eyes are distinct, the lower eyelid scaly, or with a transparent disk. Body fusiform or sub-cylindrical, elongate. These reptiles burrow in dry sand, and are peculiar to the anciently-known continents and certain islands. Some have a wedge-shaped head, with prominent rostral plate. Of these the genus Sphenops has more developed limbs, each dividing into four toes; and the only species, S. sepsoides, inhabits Egypt and other parts of North Africa. Sphenocephalus has a more slender and elongate shape, and the limbs are placed more distantly apart; the anterior minute, and fitting into a groove, the posterior as large as in Sphenops, and each of them having but three toes, of which the innermost and next are sub-equal, and the outer much shorter. The only known species, S. tridactylus, is common in Afghanistan. In Scelotes the anterior limbs disappear altogether; and the only known species, S. bipes, inhabits South Africa. Other genera have a pyramidal head, with the rostral plate erect, and rounded in front. Such are the five following, each founded on a single species:—Gongylus ocellatus, from North Africa and the borders of the Mediterranean; Thyrus Bojeri, from the Mauritius; Amphiglossus astrolabi, from Madagascar; Seps tridactylus, from the south of Europe and north of Africa; and Heteromeles mauritanicus, from North Africa. The last has only two toes to the fore-feet, three to the hind; and Seps has three toes to each foot, while the other three genera have five to each foot. In general these animals are found in dry and elevated spots, where they hide themselves in the sand or under stones.
The Scincidæ have the head covered with shields, which are symmetrically arranged. Tongue slender, free, extersile, terminating 102 in two pointed lobes. Scales on the back rounded, quincuncial, imbricate; those on the belly similar to those on the back and on the sides. No fold across the throat or along the side; no femoral or inguinal pores. Tail generally long, rounded, fragile. Eyes and eyelids well developed. Nostrils in a separate plate, between the frontal and labial shields. Generally four limbs, moderately developed, sometimes feeble or hidden below the skin. The species of this family are exceedingly numerous, and inhabit almost every part of the tropical regions, some extending into the temperate zones. They are thoroughly land Lizards, preferring dry ground, and hiding themselves in the sand, under stones, fallen leaves, &c., very few of them entering the water. They do not attain to any considerable size, only a few species of Australia and the West Indies growing to the thickness of a man's wrist, and exceeding a foot in length. Some of them are viviparous, others deposit from eight to twelve globular eggs. Dr. Gray divides them into the sub-families of Scincinæ, or those which have the scales thin, smooth, and neither striated nor keeled; the nostrils in a single smooth plate, without any lunate groove behind; and the tail round, tapering, unarmed; and Tropidophorinæ, or those which have the scales thick, bony, rugous, striated, and with one or more keels upon each of them; 103 the rostral plate rounded in front, and the body fusiform, with well-developed limbs, which terminate always in the full complement of toes. A few species of the Scincinæ have no external limbs, thus approximating in their appearance to certain of the burrowing Ophidians.]
The Orvet, or Blind-worm, Anguis fragilis, is small, cylindrical in shape, about eleven or twelve inches in length, and having the exterior appearance of Snakes. The scales which cover the body are small, smooth and shining, being red in the middle, and edged with white, of a silvery yellow on the upper part, and dusky beneath; the sides somewhat dusky brown, and the throat slightly marbled with white, black, and yellow. Two larger spots appear, one above the muzzle, the other upon the back of the head; from this point two blackish longitudinal rays start, which extend to the tail, as well as two other nut-brown rays, which start from the eyes; the markings vary, however, in different countries, and probably with age and sex.
The Orvet is found in woods and dry, sandy, and stony wastes. They are timid, harmless creatures, retiring into holes and concealing themselves in moss at the foot of trees to hide themselves from observation. They feed upon worms, insects, and the smaller mollusks. Although perfectly harmless, the 104 country-people are strongly prejudiced against them, believing their bite to be a deadly poison. This animal is extremely brittle. Laurenti and others assert that when captured it throws itself into a position of such rigidity that it sometimes breaks in two, and that a smart blow of a switch will at any time divide it.
[There are little-known species of Anguis in India and South Africa, which are at least provisionally so considered, and certainly do not differ essentially; and next we come to forms in which the limbs are successively more developed. Such are the Ophiodes striatus of Brazil, which has two short, flattened, undivided, and one-pointed limbs, corresponding to the usual hind pair; the Brachymeles bonitæ of the Philippines, in which there are two pairs of short and rudimentary limbs, the fore bearing two minute claws, while the hind are undivided; Venira bicolor, of the same archipelago has very short limbs, the fore and hind being placed distantly apart, but in this genus all have five distinct toes; Chiamelea lineata, from some part of India, and Hagria Vosmaërii, from Bengal, are kindred forms which conduct to the genus Eumeces, the species of which are very numerous, and spread over nearly all the different countries between or near the tropics, and in certain of them (as the Burmese E. anguinus) the limbs are still remarkably diminutive, and (as in E. isodactylus of Cambodia) the fore and hind limbs are placed very far apart, the body and tail being long and anguiform. In various other species of Eumeces, however, the proportions are more those of an ordinary Scink, as again in the kindred genera Mabonia and Plestiodon, which are widely distributed.
In other series of Scinks, the distinctions of which are far from being conspicuous, we again have limbless genera, or nearly so, as the Australian Soridia lineata, which has one pair of small, posterior, undivided extremities; while in another Australian form, the Rhodona punctata, the anterior pair of limbs are simple and undivided, while the hinder divide into two unequal toes, and the two pairs of limbs are situate as distantly apart. And thus we may continue to trace the successive gradations, in sundry genera, until we arrive at the Scincus officinalis of North Africa, a well-known reptile, the geographical range of which extends eastward into Afghanistan, and which was formerly in considerable request 105 for its supposed medicinal properties. Indeed, this notion still prevails in Hindustan, into which country dried specimens of both this reptile and of Sphenocephalus tridactylus (p. 101) are brought by Afghan traders, and are sold in the bazaars. Both of these are Sand Lizards, which burrow into the sand with great rapidity.
We now come to the Tropidophorinæ, or second sub-family of Scinks indicated by Dr. Gray (vide p. 102), which have always well-developed limbs, the body only moderately elongated, and the scales variously keeled. Several species of larger size appertain to this series, as the Cyclodus gigas of Australia, and the curious Stump-tail Lizards, Trachydosaurus rugosus and T. asper, of the same insular continent, which latter have most prominently rugous scales, and the tail literally appearing like the short and abrupt stump of one. Egernia Cunninghami and Tropidolesma (of different species) are other comparatively large Australian Lizards; and examples of most of those that have been mentioned may generally be seen alive in the London Zoological Gardens, where the Cyclodus gigas has bred and proves to be viviparous. Of the species of Euprepes, of which several inhabit the Indian region, some (as the very common E. rufescens) are viviparous, and others (as E. multicarinata) are oviparous. These have three more distinct, though not prominent, keels upon each scale; and the different species inhabit both the Old World and the New, as well as Australia. The Galliwasps (Celestus) of the West Indies, and sundry other genera, do not greatly differ. Of Tropidophorus, which has exceedingly rugged scales, the species inhabit the Indo-Chinese countries, and one (T. cocinsinensis) is found likewise in the Philippines; while of another (T. Berdmorei), in Burmah, Mr. Theobald remarks that "its scales are dull and lustreless, and the coloration peculiar for a Scink. It harbours under half-immersed stones, and enters the water and gravel freely." In several of this family of Lizards the scales are beautifully iridescent, and many of them show longitudinal pale or white lines, or are otherwise variegated.
Nearly akin to the extensive family of Scincidæ, there are three small families (as classed by Dr. Gray), the species of which are peculiar to Australia. They have small, undivided, posterior limbs only, or are quite limbless. These families are the Lialisidæ, founded on three or more species of a single genus, Lialis; the 106 Aprasiadæ, founded upon one species only—Aprasia pulchella, which is limbless; and the Pygopodidæ, comprising the two genera Pygopus and Delma, the former containing two, the latter only one ascertained species. The Gymnopthalmidæ constitute still another small family, quadrupedal, but with the limbs small and weak. Of seven genera referred to it, five are Australian, one is European, and one belongs to South America. Ablepharus pannonicus is a small Lizard of this family, inhabiting Eastern Europe, with a congener, A. bivittatus, in the Caucasus; and Gymnopthalmus lineatus inhabits Brazil and the Island of Martinique.
In the second tribe of Leptoglossa, entitled Cyclosaura, the scales of the belly are square, in cross bands; those of the back and tail are rhombic and imbricate, or circular and subgranular; the tongue is lengthened, and more or less conspicuously furcate; and the eyes are diurnal, having two valvular lids. The limbs are generally well developed; but in several genera they still are more or less rudimentary, or even absent.
There are four small families in which the sides are rounded and covered with scales like the back. Of these, that of Chamæsauridae is founded upon the South African Lacerta anguina of Linnæus, now Chamæsaura anguina, which has the limbs quite rudimentary. In the American families of Cercosauridæ, Chirocolidæ, and Anadiadæ, the limbs are moderately developed, and have each five toes. The two last-mentioned families are founded each upon a single species, Chirocolus imbricatus and Anadia ocellata; and the other contains the two genera Circosaura and Lepisoma—of which the first comprises some two or three species only. All of these reptiles have exceedingly long tails, though not so inordinately long as in the Lacertidæ of the genus Tachydromus.
Certain other families have a distinct longitudinal fold, covered with small granular scales on each side. These are the families Chalcidæ, Holaspidæ, and the more extensive one of Zonuridæ. The Chalcidæ have the head covered with regular many-sided shields, and the lateral fold is indistinct; limbs small and rudimentary, and the hind feet are undivided in the genera Chalcis and Bachia, with three tubercles in place of toes in Microdactylus, and with four clawed toes in Brachypus. Each of these genera is founded on a single species, and all are doubtless peculiar to the 107 New World. The Holaspidæ is also founded on one species only, the Holaspis Guentheri, which again is supposed to be South American. It has four well-developed limbs, a double row of plates along the back and upper surface of the tail, and the latter organ is curiously serrated laterally.
The Zonuridæ constitute a considerable family, to which some eighteen or twenty genera are assigned, and which present considerable modification of form. The ears are distinct, whereas in the Chalcidæ they are hidden under the skin. The head is pyramidal, or depressed, and covered with regular many-sided shields; eyes with two valvular lids. Limbs mostly well developed, but short in some, and rudimentary, or even wanting in the so-called "Glass-snakes" which constitute the sub-family Pseudopodinæ. There is no external trace of them in the North American Glass-snake, Ophisaurus ventralis; and in the Old World genus, Pseudopus, there is only one pair, posterior, rudimentary, and undivided. These reptiles are long, and serpentiform in shape: whilst in other Saurians the whole skin of the belly and of the sides is extensible, the extensibility is limited in the "Glass-snakes" to a separate part of the skin; and, as Dr. Günther remarks, "the scaly covering of the upper and lower parts is so tight that it does not admit of the same extension as in Snakes and other Lizards; and the Pseudopus, therefore, could not receive the same quantity of food in its stomach as those animals, were it not for the expansible fold of the skin running along each side of its trunk." One species of Pseudopus, the P. Pallasii, inhabits Asia Minor and the south-east of Europe; and there is another, P. gracilis, in the Indo-Chinese countries (or those lying eastward of the Bay of Bengal). A second sub-family, Gerrhonotinæ, is peculiar to America, and consists of more ordinarily-shaped Lizards, which are ranged in four genera. Together with the Ophisaurus, or American Glass-snake, they are the only known Zonuridæ that inhabit the New World. The great mass of this family and all of its most characteristic species are African, and these are arranged by Dr. Gray under the sub-families Cicigninæ and Zonurinæ. In the first of these sub-families the tail is smooth, or unarmed, and in the second it is spinous. The Cordules, Cordylus, Zonurus, &c., are very characteristic Lizards chiefly of Southern Africa, several 108 species of which have been figured by Sir Andrew Smith. They are mostly of shortish form, and the neck is more or less spinous; the body-scales in some (as Zonurus cataphractus) being extraordinarily rugous. These Lizards squeeze themselves into crevices in the rocks, in which they hold on so firmly by their nuchal spines that it is next to impossible to dislodge them, the tail commonly giving way at once if it be attempted to pull them forth by means of it.
The family of Lacertidæ, comprising our ordinary European Lizards, have no longitudinal fold along the sides, but generally one across the throat; the tail is very long, rounded, with its scales arranged in rings, being also fragile; the head is covered with shields, which are symmetrically arranged; scales on the back granular or rhombic; on the sides granular; on the belly largely quadrangular or rounded, and arranged in cross-bands; eyes diurnal, with eyelids; the tympanum distinct; limbs always four, and well developed. This group of Lizards has no representative in America or (so far as known) in Australia.
The sub-family of Tachydrominæ is included by Dr. Gray in the family Zonuridæ. These are Asiatic Lizards, with a most inordinate length of tail, the fore and hind limbs being not placed distantly apart, as in the various anguiform Lizards already treated of—there is an indistinct collar, and the toes are not serrated or keeled. Two genera have been distinguished, Tachydromus and Tachysaurus, the latter founded on a Japanese Lizard, T. japonicus. At least three species are known of Tachydromus, two of which inhabit China, T. septentrionalis and T. meridionalis; the third belonging to the Indo-Chinese countries, T. sex-lineatus. In an example of the last, measuring fourteen inches long, the tail occupies eleven inches and a half. It is the longest-tailed creature that we have any knowledge of, in proportion to its other parts; indeed, something quite wonderful to behold and muse over.
The rest of the Lacertidæ are chiefly from Africa and the south of Europe; there are probably more of them to be discovered in Middle Asia, and only three or four species are known to inhabit the Indian region. Fifteen or more genera are recognised. In temperate Europe (inclusive of the British Islands) two species 109 are common—the Zootica vivipara and the Lacerta agilis. The former, as its name imports, is viviparous, whereas the other genera belonging to the family are (so far as known) oviparous. Others occur in the south of Europe.]
The common Grey or Sand Lizard (L. agilis), sometimes attains the length of from eight to ten inches, of which the tail occupies more than half. These little inoffensive creatures, so common in Southern Europe, are slender and active; their movements are so rapid that they escape the eye as quickly as a bird. They require a mild temperature, and seek shelter among ruins. When the sun strikes with its meridian force upon a wall, they may be seen basking in its rays, enjoying themselves delightedly upon the heated surface. They seem to be pervaded with the blessed warmth, and mark their pleasure by soft undulations of the tail. It is commonly said that the Lizard is the friend of Man, since far from flying at his approach, they seem to regard his appearance with great complacency. They pass the winter at the bottom of small holes which they have hollowed out of the earth, where they become torpid. At the commencement of spring they issue from their hiding-place, and each seeks its mate; they go in pairs, male and female, it is said, living in faithful union for many years, sharing between them the domestic arrangements, which comprise hatching the young and nursing them in their helplessness, carrying them into warm and sunny places, and sheltering them from cold and damp.
Lizards feed chiefly upon insects, and especially flies. All who have watched the actions of the Grey Lizards must have observed that the caudal vertebræ are so extremely fragile that they separate on the slightest touch, the tail remaining in the hand of any one attempting to seize it. These tails sometimes grow again. When an attempt is made to seize a Grey Lizard on the wall it lets itself fall to the ground, and remains there a moment immovable before attempting to run, evidently simulating death.
Grey Lizards are easily tamed, and appear happy in captivity. From their extreme gentleness they soon become familiar with their keepers, and return caress for caress, approaching mouth to mouth, and suck the saliva from between their lips with a grace that few people would allow them to display. 110
In the Green Lizard, L. viridis, the scales of the temple are many-sided and unequal, with a central layer; back granular and oblong, with shelving sides; throat fold distinct. Nothing can be more brilliant than the variegated colouring with which it is ornamented. Its favourite locality is a slightly elevated woody place, where the sun's rays readily penetrate. It is also found in sunny meadows. It feeds upon small insects, and shows no alarm at the presence of Man, but stops to look at him. Snakes, on the contrary, they seem to fear much, but when they cannot avoid them they fight courageously. In length they are about eighteen inches.
Green Lizards are found in Jersey and Guernsey, and other warm countries of Europe, on the African coast of the Mediterranean, and they are not rare in France.
How often have we admired their magnificent colours in the neighbourhood of Montpelier, where they rival the green of the meadows, and glitter in the sun like so many living emeralds!
In the Ocellated Lizard, L. ocellata, the upper part of the body 111 is green, variegated, spotted, and reticulated or ocellated with black, having large round blue spots upon the flanks; the underpart of the body is white, frosted with green; in size it is about twenty inches. They are found at Fontainebleau, in the south of France, and in Spain. They establish themselves in hard sand, often between two beds of calcareous rock, upon some steep declivity, more or less directly exposed to the south; they are also found between the roots of old stems, either in hedgerows or vineyards. They feed almost exclusively on insects; but are said to attack Mice, Shrews, Frogs, and even Snakes, and to destroy the eggs of the Partridge. They have sometimes been tamed by feeding them on milk.
[In the genus Ophiops, two species of which inhabit Asia Minor, and one of them the shores of the Mediterranean, the eyelid is rudimentary and the eye exposed, whence the name, signifying "snake eye." So far as known, the habits of the various Lizards which constitute the family of Lacertidæ are much the same.
The family of Teidæ is peculiar to the New World, and some of the species attain to the length of several feet. In these Lizards the head is pyramidal, and is covered with regular many-sided shields; supra-orbital plate horny; the teeth solid and well rooted; tongue elongate, flat, free (rarely slightly sheathed at its base); the scales of the back are regular and keeled, and of a rhombic shape; sides flat, and covered with small granular scales; the throat scaly, with a double collar, rarely indistinct.
In some the throat has two cross-folds, with large six-sided scales within; and of these some have the ventral shields small, long, and smooth, while others have them much broader. The former are known as the Teguexins (Teius and Callopistes), and the latter as the Ameivas (Ameiva, and three other genera). One species of Teguexin, Teius teguexin, may commonly be seen alive in the London Zoological Gardens. This is a large and powerful Lizard, exceeding five feet in length when full grown, and extremely active. It feeds on small living animals of any kind, and will even devour poultry, and especially their eggs, for which latter it manifests an especial liking, as observed in captivity. Sometimes it has been known to prey on other and kindred Lizards, as the Ameivas. The teeth of this species are strong, 112 and the reptile can bite with great force. It is a bold and determined combatant when attacked, and if it succeeds in seizing its foe, retains its hold with pertinacity. Its flesh is eaten by some people, who consider it excellent. Together with a second species, T. nigropunctatus, it inhabits Brazil, and the two species of Callopistes are also South American, one at least of them occurring in Chili. The species of this family, although strong and agile, never ascend trees, but range at will the hot sandy plains or the dense and damp underwood on the margins of lakes and rivers, into which they plunge when alarmed, and remain below the surface until the danger has passed away, their capacious lungs and imperfect circulation permitting them to endure a very long immersion without inconvenience.
The Ameivas have a long whip-like tail, and peculiarly elongated toes on their hind feet. The species of Ameiva and Cnemidophorus are numerous, and the genera Dicrodon and Acrantus are founded each of them upon a single species. In general these are Lizards which correspond with the ordinary Lacertidæ of the Old World. One species only, Cnemidophorus sex-lineatus, inhabits the Southern States of North America; there are at least four others in Mexico, and the rest belong to South America and the Antilles. "The Ameiva dorsalis," writes Mr. Gosse, "is one of the most common of the reptiles of Jamaica, and is as beautiful as abundant. Its colours are striking, but not showy, and its countenance has a very meek expression. All its motions are elegant and sprightly; when it is proceeding deliberately, its body is thrown into latent curves the most graceful imaginable; but when alarmed its swiftness is so excessive that it appears as if it literally flew over the ground, and the observer can scarcely persuade himself that it is not a bird. It is very timid, and though its toes are not formed as in the Geckos and Anoles, for holding on against gravity, I have seen a large Ameiva run with facility on the side of a dry wall, along the perpendicular surfaces of the large stones."
A second series occurs in those Teidæ which have a collar of large shields on the throat. As many as five genera of them have been established, each upon a single species, and all are from intertropical America. In Crocodilurus lacertinus the two rows 113 of crests along the tail recall to mind the Crocodiles, whence the name bestowed. Others have been styled Dragons, as the Great Dragon, Ada guianensis, and the Smaller Dragon, Custa bicarinata. All bear a certain amount of superficial resemblance to the Crocodiles, and the Great Dragon grows to six feet in length, and is found in many parts of South America. This large reptile runs up the trunks of trees with facility, is quick when on the ground, and it also swims, though not particularly well. It preys upon such small animals as it can manage to seize, and chiefly frequents the inundated savannahs and marshy localities, where it is seen basking in the sunshine; but there is considerable difficulty in taking this Lizard, as it makes generally for its burrow in some raised spot, and bites desperately in self-defence. Its flesh is eaten, and is considered a delicacy. Its eggs, also, are considerably esteemed at Cayenne and other places, and each female lays some dozens of them.
The family of Helodermidæ is founded on a very remarkable Lizard from Mexico, the H. horridum, which is of the same size as the Great Dragon, and in some respects approximates the following Old World family of Varanidæ. Its back and sides are covered with oblong, hexagonal, very convex and shield-like scales, and the belly with oblong, rather convex plates; tail cylindrical, with oblong, convex scales above, and flat, elongate, thin plates beneath. The head is somewhat flattened, and is covered with polygonal, convex shields; the muzzle is rounded; and the teeth are on the inner side of the jaws, incurved, with a groove on the front of their inner side. The bite of this reptile is said to be severe.
The family of Varanidæ inhabit South-eastern Asia and its islands, Africa, and Australia. In this family are comprised the largest of existing Lizards, with the exception of the Crocodilidæ. They are very commonly miscalled Iguanas by Europeans and their descendants, in the countries where they are found. These reptiles have a pyramid-shaped head, more or less elongated, and covered with small and scale-like, but not imbricate, shields. Their teeth are acute and compressed. The tongue is elongate, slender, terminating in a long fork, and is retractile into a sheath at its base. Their scales are small, equal on the sides and on the back, and arranged in cross rings; those on the belly and tail are 114 square, in cross bands. Tail long, and generally more or less compressed. The feet are well developed, with five toes on each, which are armed with strong claws. Most of them live near water, and they are excellent swimmers, their long and compressed tail serving as a propeller. Their movements on land are not much less rapid than in the water. Several of the species climb trees, and they are more or less nocturnal in their time of action, though also about by day. They are exclusively carnivorous, feeding on the different water animals, and on the eggs of birds, and likewise on those of other large reptiles; some of them are also destructive to ducklings, and to various Snakes. Dr. Günther remarks that "their external nasal opening leads into a spacious cavity situated in the snout; when the animal dives, it closes the nasal aperture, and retaining a certain quantity of air in that pouch, or rather in the two pouches, it is enabled to remain under water for a prolonged period without the necessity of rising to the surface in order to breathe. It is the same plan of structure as that with which a large northern Seal (Cystophora borealis) is provided." In like manner, the air-bag connected with the one developed lung of the Ophidians retains the necessary supply of air during the tedious process of deglutition or swallowing. The nostrils are variously placed, either mid-way between the eye and muzzle, or nearer to one or to the other; and according to this and some other differences, Dr. Gray divides the Varanidæ into as many as seven genera, but Dr. Günther would seem to admit not more than two genera. When the tail of these Lizards is mutilated, the lost portion is never renewed; whereas in the preceding families of the Zonuridæ, Lacertidæ, and Teidæ a new tail or portion of one soon sprouts forth—but this renewed portion contains no bony vertebræ, and it remains smooth externally; when the fracture is cleft, as sometimes happens, two new tails are put forth. Another family of Lizards in which the tail is thus commonly renewed is that of the Geckos; but never in the Iguanidæ, the Agamidæ, and the Chameleonidæ, any more than in the Varanidæ. The species of this family defend themselves vigorously, when attacked, by lashing forth smart blows with the tail, as do also the Crocodiles and the larger Iguanidæ.
In the genus Varanus, the nasal apertures form an oblique 115 slit, in, or nearly in, the middle, between the eye and the tip of the snout. The scales are elliptic and small; those on the back and on the sides are not imbricate, each of them being surrounded by a small, circular, granular fold. Tail with a low crest, formed by two or four series of strongly keeled scales. Throat with a transverse fold. One very common in India and Ceylon is the V. dracæna, which grows to a length of five feet, the tail being longer than the body. These reptiles live in holes, and in mid-day they steal out of their cells to seek their food, which consists chiefly of the smaller reptiles and of insects. In many parts of India, and in Ceylon, the flesh is much eaten by the natives. The late Dr. Kelaart states that he once tried some excellent soup made from it, which tasted not unlike hare-soup. At Trincomali, he tells us, they are hunted down by Dogs, and sold in the market for sixpence each. This species climbs walls, and holds on so firmly with its strong claws, wherever these can be inserted, that it is actually used by house-breakers in India to help in raising themselves up a wall or building, the man grasping the tail, while the reptile affords a lift by endeavouring to escape from him upwards. It lays twenty or thirty eggs, which in texture and appearance resemble those of many Snakes, being similarly agglutinated together by a viscid mucus. Sir J. E. Tennent remarks that "one of the earliest, if not the first, remarkable animal to startle a stranger on arriving in Ceylon, whilst wending his way from Point de Galle to Colombo, is this large Lizard, which may be seen at noonday searching for Ants and other insects in the midst of the highway and along the fences. When disturbed, but by no means alarmed, by the approach of Man, it moves off to a safe distance; and the intrusion being at an end, it returns again to the occupation in which it had been interrupted. It lives in any convenient hollow, such as a hole in the ground, or the deserted nests of the Termites; and some small ones, which frequented my garden at Colombo, made their retreat in the heart of a decayed tree."
Of another species, V. flavescens, which inhabits Lower Bengal, and to the eastward in Burmah, &c., Mr. Theobald remarks that "large specimens are not often procurable by Europeans, as they are much sought after by both Burmese and Karéns as choice articles of food. They are chiefly hunted with Dogs, whose scent 116 enables them to discover the Varans in the hollow trees in which they habitually shelter themselves. A Burman, though ordinarily a lazy man, will think nothing of cutting down and breaking up a large tree in which one of these creatures has sought refuge. The Varanidæ deposit their eggs in the ground, usually selecting a deserted White-ant's nest. The eggs are cylindrical, with tapering ends, of a dirty white colour and leathery texture (those of V. dracæna are two inches long), and, being esteemed an uncommon luxury by the Burmese, sell dearer than fowls' eggs. They are oily and feculent-looking, though devoid of any nauseous odour, and some Europeans eat them with pleasure."
A well-known African species, the V. or Psammosaurus scincus, extends (without the slightest difference) to the extreme desert region of the north-west of India, and more habitually frequents dry localities than others. In this species the nasal apertures are placed very near the eyes.
In the genus Hydrosaurus, the nostrils are more or less rounded, and are situate near the extremity of the snout. These animals are more decidedly aquatic than the preceding, and some of the species grow to seven or even eight feet in length. Such is the H. giganteus of Australia, where three, if not four, species inhabit. In all south-eastern Asia and its islands, its range extending to Lower Bengal but not to India proper, although found in Ceylon, the H. salvator is a common species, which, according to the late Dr. Cantor, is "very numerous in hilly and marshy localities of the Malayan peninsula. It is commonly, during the day, observed in the branches of trees overhanging rivers, preying upon birds and their eggs and smaller Lizards, and when disturbed it throws itself from a considerable height into the water; it will courageously defend itself with teeth and claws, and by blows with its tail."
We have now to treat of the
Which are those Lizards which have the tongue short, thick, attached to the gullet, and not exsertile. These fall under two very distinct tribes—the Strobilosaura and Nyctisaura of Dr. Gray, or 117 the tribe of the Iguanas and their kindred, and that of the Geckos and their kindred. The tribe of
Have the scales of the back and sides imbricate, generally rhombic, and those of the lower parts imbricate and of small size. Tail with more or less distinct whorls of scales. The eyes diurnal, with round pupil, and valvular lids. Feet with toes of very unequal length. Many of these reptiles have a row of spines or spine-like scales along the back and tail, which in some are very long, while others have high dorsal and caudal crests, an expansile gular pouch, or other adornments. Like the Varans among the Leptoglossa (p. 114), these Lizards do not renew the tail, or a portion of it, after mutilation. There are two great families of them—one peculiar to the Old World with Australia, the other to the New World; but as families they do not differ much, and might very well be retained as divisions of the same extensive family.
In the family of Iguanidæ, all of which inhabit America or its islands, the teeth are round at the root, dilated and compressed at the tip, and toothed at the edge; they are placed in a simple series on the inner side of the jaws, just below the edge, and are covered on the inner side by the gums; as they fall out they are replaced by others, which grow at the base of their predecessors, and gradually cause the absorption of their roots. Probably not fewer than a hundred and fifty species are now recognised, which are distributed under more than fifty genera. We can only notice a few of the most remarkable of these Lizards, some of the larger of which attain a length of five or six feet, with proportionate bulk of body. As a general rule, the larger species are mainly herbivorous, while the smaller are chiefly insectivorous, though many of the latter also devour fruit. As most of them are remarkable for their rapid changes of colouring, the name of Chameleon is often misapplied to them, in the supposition that the Chameleons are the only Lizards in which that curious phenomenon is observable. In one remarkable species, the Sphærops anomalus, inhabiting Brazil, it is stated that the eye nearly resembles that of the true Chameleons, and it is also one of those which are particularly celebrated for its changes of hue.] 118
The name Iguana was given by Laurenti to a heterogeneous group of Saurians, various forms being included which were first separated by Daudin. The Iguanas, as thus restricted, are characterized by a very large thin dew-lap under the neck, a double row of small palatal teeth, and a crest on the back and tail; the latter long, slender, compressed, and covered with small imbricated and carinated scales. Messrs. Duméril and Bibron describe the genus, thus modified, as principally remarkable for the cutaneous prolongation which constitutes the deep and thin dew-lap, or pouch, the free border of which describes a curved line, and is dentated at the part nearest the chin. The head is moderately long, and has the form of a pyramid with four faces. The neck is slightly compressed, the limbs long, the toes unequal and sometimes denticulate on the edge. The five toes of the posterior feet are graduated; the tail, which is long and slender, is slightly flattened from right to left. 119 The Iguanas live chiefly on trees, but they take readily to the water, swimming with great facility.
There are numerous species, all of which are found in South America and the Antilles. In the Island of Isabella, Sir E. Belcher found swarms of them which he had reason to consider omnivorous, feeding voraciously on birds' eggs and the intestines of birds and insects.
The Common Iguana, I. tuberculata, which inhabits a great part of South America, is one of the best known species of this family. These reptiles are easily recognised from the large pouch underneath the neck, and the dentated crest which extends from the head to the extremity of the tail. The tail, feet, and body are covered with small scales. On the upper part, their colour is a more or less decided green, sometimes becoming blue, at others slate-coloured; the lower part is of a yellowish green. The sides present zigzag, roundish, brown scales, edged with yellow; frequently a yellow line is traced obliquely in front of the shoulder, and some individuals are sprinkled with brown; others have the limbs spotted with brown on a black ground. The tail is surrounded with brownish rays alternating with others green and yellow. When full grown it attains the length of four feet, but the more ordinary length of the animals is about thirty inches. They are very gentle creatures, and perfectly harmless, feeding almost exclusively on vegetables. They are hunted in America for their flesh, which is excellent; and they are especially common at Surinam, in the neighbourhood of Cayenne, and in Brazil.
[Of a kindred species, Metopoceros cornutus, which also is common in the Antilles, an excellent description has been published by Lieutenant Tyler,22 which we must endeavour to condense. This reptile attains a length of five, and sometimes even of six feet, the tail being about twice and three quarters the length of the body. When first hatched it measures four inches. The mouth is large, and is armed with two rows of maxillary and two of palatal teeth, which appear simply to be intended to crop leaves and to provide the stomach with vegetable food. Each maxillary tooth is a little double-edged saw, and they are so lapped over each other that the reptile, in closing its mouth upon 120 a leaf, cuts through it completely. The tongue is curiously used by the animal to draw food into the mouth, and to forward it down the gullet, or to repel it at will, and the only use of the palatal teeth appears to be to secure the food while the tongue moves forward to afford fresh assistance in its journey down the throat. The tongue is always covered by a glutinous secretion, which is perceptibly appended to the jaws when the mouth is open. Between the lower jaw and the chest is a pouch, which the animal draws in or extends simultaneously with the compression or swelling out of the body when enraged or excited. The portion of the gular pouch attached to the jaw is inflatable, and food is sometimes retained in it for a considerable period, but the lower part is merely extensible.
"Whilst always retaining the same colours, this Iguana has the power of considerably changing its hues; but these changes are gradually performed. The colours become more dull as the period of the change of cuticle approaches—which is not, however, very frequent. Each scale has its own tint, and the colours being thus irregularly blended, an appearance is given, particularly to the younger reptiles, very much like that of worsted-work.
"These Iguanas live principally on trees, and near the windward coast of the island" (of St. Lucia). "They are not much seen, excepting in the months of February, March, and April, when they quit their hiding-places, and repair to the sea-shore or other sandy places to lay their eggs in the sand. The older females lay a great number of eggs. I have known an instance of one in confinement laying five in one day, and thirty-two within the space of ten minutes five days afterwards, making thirty-seven in all. Younger females are much less prolific, according to their size. The eggs are very liable to destruction by Ants, which fact probably accounts for their being usually deposited in sea-sand. They are soft, and without any white, and their shell resembles the most beautiful kid leather used for French gloves, of a very light straw-colour. They are about the size of those of a domestic Pigeon, but rather longer; but they vary in dimensions according to the age and size of the Iguana.
"This Iguana is not averse to water, when not too cold, taking 121 to it only when the sun is shining; in fact, not moving about much at any other time. Its mode of swimming differs from that of other Lizards, inasmuch as it places its four legs close by the side of its body, and swims entirely with its tail. It dives with great facility, and remains sometimes for a considerable time under water. I believe that it never ventures into the sea. The tail is a very valuable limb; for, besides being the sole means of swimming possessed by the animal, it is of great use in climbing trees, although not prehensile; and it is a most important weapon of defence, a blow from it being frequently sufficient to inflict a severe wound. In fact, this reptile is rather formidable when brought to bay in the woods. It is hunted by the natives with Dogs trained for the purpose. The Dog, immediately upon scenting it, gives tongue, and, if on the ground, the Dog seizes it by the back, and either kills it or maims it, which makes its capture easy; if in a tree, the Iguana is either shaken down—a matter ordinarily of no small difficulty—or the branch is cut off. It is almost useless to attempt to find these reptiles without Dogs, as the resemblance of their colour to that of the trees which they inhabit prevents them from being easily seen. Few Dogs but those accustomed to the sport will touch them, as, in addition to the blows which they inflict with the tail, they bite and scratch furiously; and when once they lay hold of anything with their teeth, they can only be made to let go by an inducement to bite some other attractive object being offered to them. They run into holes when chased, if an opportunity offers, and when their eyes are hidden from view, they fancy that their whole body is safely covered. The flesh, particularly of the female, is a great delicacy; it is cooked in various ways, sometimes in a fricassee, with the eggs whole, sometimes roasted or stewed. The eggs have a very glutinous consistence. The flesh is said to disagree with some constitutions.
"Unless when caught young, it is very difficult to induce these reptiles to feed in confinement, and particularly when watched. Their disposition is sulky and savage, and I have known some of them," continues Lieutenant Tyler, "to die in confinement from starvation, rather than feed. This has caused me to try the following plan, which I find very successful, of affording them 122 nourishment:—I hold them by the lower part of the body with one hand, and with the other I irritate them until they open their mouth and attempt to bite, when I insert food; and by annoying them in this way, I have not only made them eat their natural food, but I have killed some of them by forcing them to eat corn and leaves, which appear to have disagreed with them. By some of the natives this Iguana is said to eat Lizards and insects; but I have opened several, and I have never succeeded in finding any but vegetable matter in the stomach."
Of the habits of a kindred species of Iguana, the Cyclura lophura, inhabiting Jamaica, Mr. Gosse has given an elaborate description; and he tells us that the gular pouch in the Iguanidæ "is extensible, but not inflatable," as is the current opinion. Holbrook and others have remarked the same; and Professor Thomas Bell describes the fold of skin as being drawn down by a peculiar arrangement of the lingual bone, and a singular cartilage fixed to it and attached also to the skin. These parts are moved by delicate muscles, so that, when the cartilage is drawn down, the skin of course is distended, and follows it "in the same way that the silk is stretched over the whalebone of an umbrella." "In fact the skin," writes Professor Holbrook, "when distended in life by the animal, does not resemble the inflated vocal sacs of the Frogs and Toads, which are round, but looks like a fold of the skin, pinched and drawn down, the two portions of it being in contact, like a dew-lap." It appears that the Cyclura, also, is exclusively herbivorous; and Mr. Gosse remarks upon the severe wounds which it inflicts upon Dogs with its sharply-serrated tail. In general, the larger species of this family are solely vegetable-feeders, while the smaller kinds (such as the Anoles) are more or less insectivorous; and there are some, of intermediate size, which even prey occasionally upon the kindred Anoles and other small animals. The genera of these reptiles are exceedingly numerous, as we have seen, and amongst so many there must be considerable variety in the habits; but we can only notice a very few of them. Within the limited area of the small archipelago of the Gallapagos, situated on the equator about ten degrees west of South America, there are two remarkable species of Iguanidæ, of which the habits have been described and commented upon by Mr. Darwin in his 123 volume of the "Voyage of H.M.S. Beagle." One of them is particularly so, because, as that naturalist observes, it is the only existing Saurian which can properly be said to be a maritime animal. In the whole of that group of islands, as he tells us, there is only one rill of fresh water that reaches the coast; yet this reptile frequents the sea-beaches, and no other parts of the islands. He adds that it is the only known existing Lizard that feeds exclusively on aquatic productions. Although he refers both species to the genus Amblyrhynchus, the aquatic sort now constitutes the genus Oreocephalus of Dr. Gray, and it bears the name of O. cristatus. This Lizard, according to Mr. Darwin, "is extremely common on all the islands throughout the archipelago of the Gallapagos. It lives exclusively on the rocky sea-beaches, and is never found—at least, I never saw one—even ten yards inshore. It is a hideous-looking creature, of a dirty black colour, stupid and sluggish in its movements. The usual length of a full-grown one is about a yard, but there are some even four feet long. I have seen a large one which weighed twenty pounds. On the island of Albemarle they seem to grow to a greater size than on any other. These Lizards were occasionally seen some hundred yards from the shore swimming about; and Captain Colnett, in his 'Voyage,' says, 'they go out to sea in shoals to fish.' With respect to the object, I believe that he is mistaken; but the fact stated on so good an authority cannot be doubted. When in the water the animal swims with perfect ease and quickness, by a serpentine movement of its body and flattened tail—the legs, during this time, being motionless and closely collapsed on its sides. A seaman on board sank one, with a heavy weight attached to it, thinking thus to kill it directly; but when an hour afterwards he drew up the line, the Lizard was quite active. Their limbs and strong claws are admirably adapted for crawling over the rugged and fissured masses of lava which everywhere there form the coast. In such situations, a group of six or seven of these ugly reptiles may oftentimes be seen on the black rocks, a few feet above the surf, basking in the sun with outstretched legs. I opened the stomachs of several," continues Mr. Darwin, "and in each case found it largely distended with minced sea-weed of that kind which grows in thin foliaceous expansions of a bright 124 green or dull red colour. I do not recollect having observed this sea-weed in any quantity on the tidal rocks; and I have reason to believe that it grows at the bottom of the sea, at some little distance from the coast. If such is the case, the object of these animals occasionally going out to sea is explained. The stomach contained nothing but the sea-weed. Mr. Bynoe, however, found a piece of a Crab in one; but this might have got in accidentally. The intestines were large, as in other herbivorous animals."
The food of this Lizard, equally with its compressed form of tail, and the certain fact of its having been seen voluntarily swimming out at sea, absolutely prove its aquatic habits; nevertheless, as we are told by Mr. Darwin, "there is in this respect one strange anomaly, namely, that when frightened it will not enter the water. From this cause, it is easy to drive these Lizards down to any little point overhanging the sea, where they will sooner allow a person to catch hold of their tail than jump into the water. They do not seem to have any notion of biting; but when much frightened they squirt a drop of fluid from each nostril. One day I carried one to a deep pool left by the retiring tide, and threw it in several times as far as I was able. It invariably returned in a direct line to the spot where I stood. It swam near the bottom, with a very graceful and rapid movement, and occasionally aided itself over the uneven ground with its feet. As soon as it arrived near the margin, but still being under water, it either tried to conceal itself in the tufts of sea-weed, or it entered some crevice. When it thought the danger was passed, it crawled out on the dry rocks, and shuffled away as quickly as it could. I several times caught this same Lizard by driving it down to a point, and though possessed of such perfect powers of diving and swimming, nothing would induce it to enter the water; and as often as I threw it in, it returned in the manner above described. Perhaps this singular piece of apparent stupidity may be accounted for by the circumstance that this reptile has no enemy whatever on shore, whereas at sea it must often fall a prey to the numerous Sharks. Hence, probably urged by a fixed and hereditary instinct that the shore is its place of safety, whatever the emergency may be, it there takes refuge. I asked several of the inhabitants if they knew 125 where it laid its eggs: they said, that although well acquainted with the eggs of the other kind, they had not the least knowledge of the manner in which this species is propagated—a fact, considering how common an animal this Lizard is, not a little extraordinary. During our visit (in October) I saw extremely few small individuals of this species, and none I should think under a year old. From this circumstance it seems probable that the breeding season had not commenced."
The terrene species, Amblycephalus subcristatus, unlike the aquatic one, is confined to the central islands of the Gallapagos archipelago, where they inhabit both the higher and damp, as well as the lower and sterile parts; but in the latter they are much more numerous. "I cannot give a more forcible proof of their numbers," relates Mr. Darwin, "than by stating that, when we were left at James Island, we could not for some time find a spot free from their burrows on which to pitch our tent. These Lizards, like their brothers of the sea-kind, are ugly animals; and, from their low facial angle, have a singularly stupid appearance. In size, perhaps, they are a little inferior to the latter, but several of them weighed between ten and fifteen pounds each. The colour of their belly, front legs, and head (excepting the crown, which is nearly white) is a dirty yellowish orange; the back is of a brownish red, which, in the younger specimens, is darker. In their movements they are lazy and half-torpid. When not frightened, they slowly crawl along, with their tails and bellies dragging on the ground. They often stop and doze for a moment, with closed eyes, and hind legs spread out on the parched soil. These Lizards inhabit burrows; which they sometimes excavate between fragments of lava, but more generally on level patches of soft volcanic sandstone. The holes do not appear to be very deep, and they enter the ground at a small angle; so that when walking over one of these Lizard warrens, the soil is constantly giving way, much to the annoyance of the tired pedestrian. This animal, when excavating its burrows, alternately works the opposite sides of its body. One front leg for a short times scratches up the soil, and throws it towards the hind foot, which is well placed so as to heave it beyond the mouth of the hole. This side of the body being tired, the other takes up the task, and so alternately. I watched 126 one for a long time," continues Mr. Darwin, "till half of its body was buried; I then walked up and pulled it by the tail; at this it was greatly astonished, and soon shuffled up to see what was the matter; and then stared me in the face, as much as to say, 'What made you pull my tail?' They feed by day, and do not wander far from their burrows; and, if frightened, they rush to them with a most awkward gait. Except when running downhill, they cannot move very fast; which appears chiefly owing to the lateral position of their legs. They are not at all timorous; when attentively watching any one, they curl up their tails, and raising themselves on their front legs, nod their head vertically, with a quick movement, and try to look very fierce, but in reality they are not at all so; if one just stamps the ground, down go their tails, and off they shuffle as quickly as they can. I have several times observed small fly-eating Lizards, when watching anything, nod their heads in precisely the same manner; but I do not at all know for what purpose. If the Amblyrhynchus is held, and plagued with a stick, it will bite it very severely; but I caught many by the tail, and they never tried to bite me. If two are placed on the ground, and held together, they will fight and bite each other till blood is drawn. Those individuals (and they are the greater number) which inhabit the lower country, can scarcely taste a drop of water throughout the year; but they consume much of the succulent cactus, the branches of which are occasionally broken off by the wind. I have sometimes thrown a piece to two or three when together; and it was amusing enough to see each trying to seize and carry it away in its mouth, like so many hungry Dogs with a bone. They eat very deliberately, but do not chew their food. The little birds are aware how harmless these creatures are: I have seen one of the thick-billed Finches (peculiar to the Gallapagos) picking at one end of a piece of cactus—which is in request among all the animals of the lower region—whilst a Lizard was eating at the other; and afterwards the little bird, with the utmost indifference, hopped on the back of the reptile. The stomachs of several that I opened were full of vegetable fibres and leaves of different trees, especially of a species of Acacia. In the upper region they live chiefly on the acid and astringent berries of the guayavita, under which trees I have seen 127 these Lizards and the huge Tortoises feeding together. To obtain the acacia leaves, they crawl up the low, stunted trees; and it is not uncommon to see one, or a pair, quietly browsing, whilst seated on a branch several feet from the ground.
"The meat of these animals, when cooked, is white; and by those whose stomachs rise above all prejudices, it is relished as very good food. Humboldt has remarked, that in intertropical South America, all Lizards which inhabit dry regions are esteemed as delicacies for the table. The inhabitants of the Gallapagos say, that those inhabiting the damp region drink water, but that the others do not travel up for it from the sterile country, like the gigantic Land Tortoises. At the time of our visit, the females had within their bodies numerous large elongated eggs. These they lay in their burrows, and the inhabitants seek them for food."
These two curious Lizards of the Gallapagos agree nearly in general structure, and in many of their habits; and neither of them has that rapidity of movement which is characteristic of various other Iguanidæ. The form of the head resembles a good deal that of a land Tortoise, and we find the same form of head, and again the same disinclination to bite, in certain herbivorous Lizards, such as the Uromastyx and kindred forms, which are referred by Dr. Gray to the corresponding Old World family of Agamidæ.]
In the family of Iguanas the Basilisk may be noted. According to ancient authors, reproduced by writers of the middle ages, the Basilisk, although such a small animal, could produce instant death by its sting. The man whose eyes met theirs was supposed to be at once devoured by an intense fire. Such are the fabulous ideas which tradition has transmitted to us about these animals. It is to be remarked, however, that the Basilisk of modern herpetology is not the βασιλισκος, or Royal Serpent, of the ancients, the Cockatrice of Scripture. The reptile which now bears the name is an inoffensive animal, living in the forests of Guiana, Martinique, and Mexico, and leaping from branch to branch, in order to gather the seeds or seize the insects on which it feeds.
The Basilisk is distinguished from the other Iguanian Lizards by the absence of the long and dilatable skin under the throat, 128 and by the presence of an elevated crest which runs along the whole length of the back and tail.
The Hooded Basilisk, B. americanus (Fig. 29), measures seven or eight inches from the nose to origin of the tail, which is itself nearly three times as long, being nineteen or twenty inches in length. Upon the occiput it has a sort of horn or bag, in shape like a hood, round at the summit, and slightly inclined towards the neck. This bag, when distended, is about the size of a pullet's egg. In the male the back and tail are surmounted by a raised crest, such as we have described above, sustained in its thickness by the knotty process of the vertebræ. The general colour is a mixture of sandy brown, slightly marbled on the back and sides, with shades of blue on the upper part, and a silvery white underneath. On the throat are larger bands of brown, and on each side of the eye is a white ray bordered with black, which is lost upon the back; and the tail is so remarkably attenuated towards its extremity as to show the articulations of the vertebræ beneath.
[According to Mr. O. Salvin, the Basilisk is very common about Lanquin, in the province of Guatemala, where it may frequently be seen on the low branches of a bush, and it is particularly fond of basking on the boughs of a felled tree in a clearing near a 129 stream. In some specimens of the males, we are informed, the tail is much more compressed than in others. In a series of the young the crest is shown in all stages of development. We also learn from this naturalist that, notwithstanding the compressed form of its tail, the Basilisk does not habitually enter the water, as most writers have supposed.
The sub-family of Anoles (Anoliinæ) have mostly the skin of their toes widened (under the ante-penultimate phalanx) into an oval disk, striated crosswise underneath, which enables them to attach themselves to various surfaces. They do not attain the large size of the Iguanas, and the habits and characteristics of the various species inhabiting Jamaica are thus vividly described by Mr. P. H. Gosse in his "Naturalist's Sojourn" in that beautiful island. "The stranger," he remarks, "walks into the dwelling-house. Lizards, still Lizards, meet his eyes. The little Anoles (A. iodurus, A. opalinus, &c.) are chasing each other in and out between the jalousies, now stopping to protrude from the throat a broad disk of brilliant colour, crimson or orange, like the petal of a flower, then withdrawing it, and again displaying it in coquettish sport. Then one leaps a yard or two through the air and alights on the back of his playfellow; and both struggle and twist about in unimaginable contortions. Another is running up and down on the plastered wall, catching the Ants as they roam in black lines over its whitened surface; and another leaps from the top of some piece of furniture upon the back of the visitor's chair, and scampers nimbly along the collar of his coat. It jumps on the table;—can it be the same? An instant ago it was of the most beautiful golden green, except the base of the tail, which was of a soft, light, purple hue; now, as if changed by an enchanter's wand, it is of a dull sooty brown all over, and becomes momentarily darker and darker, or mottled with dark and pale patches of a most unpleasing aspect. Presently, however, the mental emotion, whatever it was—anger, or fear, or dislike—has passed away, and the lovely green hue sparkles in the glancing sunlight as before."
The green colour of certain of these Anoles so closely resembles that of foliage, that they are apt to be overlooked. Thus Mr. Gosse was about to throw a net over a Butterfly, when, as he remarks, "on a slight rustle among the leaves, I observed that it 130 was fluttering as if unable to get away. My impression was that an invisible Spider's-web was holding it; but, looking closer, I found that a little green Anolis had the Butterfly in its mouth. Its colour was so exactly that of the verdant leaves of the bush, that I had not perceived it before, although my eyes were fixed on the spot. I have also observed the same species feeding on Ants. On a gateway a number of scattered Ants of a small kind were running to and fro, as they very frequently are seen to do. A beautiful male Anolis had stationed himself on the post perpendicularly, with the head downwards, and as the Ants one by one came near him he snapped them up. Each capture was the work of an instant; he touched the post with his muzzle, and the Ant was gone: they were evidently seized with the lips, not with the tongue. These little creatures are as playful as they are pretty. As they creep about they often catch sight of another of the same species; immediately one suddenly raises and depresses the head and fore-parts, flirts the tail from side to side, and extends the goitre by means of the elastic arched bone in front, till its tip reaches nearly as far as the muzzle. The brilliant goitre is thus alternately extended and relaxed several times. After being thus 'signalized' for a few seconds, one darts towards the other, who usually runs away, apparently as if wishing to be caught." Elsewhere Mr. Gosse describes the noosing of an example of a fine Lizard of this Anolis group, the Dactylæ Edwardsii, which is also a native of Jamaica, "about a foot long, and of a lively green colour. He was very savage, biting at everything near: presently his colour began to change from green to blackish, till it was of an uniform bluish black, with darker bands on the body, and a brownish black on the tail; the only trace of green was just around the eyes." He was placed in a cage, and "at night," continues Mr. Gosse, "I observed him vividly green as at first—a token, as I presumed, that he had in some measure recovered his equanimity. The next day he continued very fierce. I hung the cage out in the sun; two or three times in the course of the day I observed him green, but for the most part he was black. The changes were rather quickly accomplished. The food of this Lizard appears to include both vegetable and animal substances. I was never able to induce one to eat in captivity; but the dissection of several has given me 131 this result. Thus in one I have found seeds and farinaceous substance; in another the fragments of a brilliant beetle of the weevil group. I once observed one deliberately eat the ripe glass-berries, munching half of one at a mouthful."23
Thus far we have treated of chiefly arboreal Iguanidæ; and although a Marine Lizard (Trachycephalus cristatus) cannot well be so designated, it nevertheless belongs to the same particular series. We have next a long series of mainly terrene genera of the same great American family, in which the body is subtrigonal or depressed. As many as twenty-two genera, with sixty-one species of the terrene Iguanidæ, were catalogued by Dr. Gray in 1845, and a good many have since been added. There is a corresponding series in the kindred Old World family of Agancidæ, and in neither instance are the majority of them ground-frequenting Lizards to any great extent. Thus, of Dr. Gray's first genus Tropidolipis (so named from its large keeled scales), and of which as many as nine species are given from Mexico, a tenth (T. undulatus, of the United States) is described by Professor Holbrook to inhabit chiefly the pine-forests, where it is often found under the bark of decaying trees; it also commonly chooses old fences for its basking-place. "It is exceedingly rapid in its motions, climbing with great facility to the tops of trees, and is hence not taken alive without great trouble. Its food consists of insects, especially such as are found under decaying wood." The colouring of this Lizard is remarkably brown, with narrow zigzag black bands above, and green below, with a white medium stripe bordered with black; throat and breast black, with a broad green band across. Various species of kindred genera were collected by Mr. Darwin, and are figured in the "Zoology of H.M.S. Beagle," and of one of these (probably Lecolænus Darwinii), which he observed at Bahia Blanca, in Northern Patagonia, he remarks that "it lives on the bare sand near the sea-coast, and from its mottled colour, the brownish scales being speckled with white, yellowish red, and dirty blue, can hardly be distinguished from the surrounding surface. When frightened it attempts to avoid discovery by feigning death, with outstretched legs, depressed body, and closed eyes: if further molested, it buries itself with 132 great quickness in the loose sand. This Lizard, from its flattened body and short legs, cannot run quickly." With others these Lizards constitute the sub-family Tropidolepinæ of Dr. Gray, which are followed by the sub-family Phrynosominæ, in which some very singular Lizards find their place. The most extraordinary of them constitute the genus Phrynosoma, four species of which inhabit Western North America. These have great spines to the occiput, in these respects resembling the African genus Cordylus (p. 107), and very Toad-like proportions, looking somewhat like Toads with short tails; and again they decidedly approximate in appearance to the curious Moloch horridus of Western Australia, which belongs to the corresponding Old World family of Agancidæ; and, like that strange reptile, they are slow of motion, and perfectly harmless, and they may be handled with impunity, as they never attempt to bite.]
Flying Lizards (Draco) have the head small, the nostrils in a scale, tubular, on the side ridge; tympanum white and opaque. They live on trees, walking with agility with their wings folded by their sides. These wings they expand 133 and use as a parachute when they throw themselves upon their prey from the tops of trees or other elevated places. But they cannot move them as birds do their wings. These remarkable appendages also serve to drive away insects.
[The fabulous Dragons of the ancient Greeks were Serpents or Lizards with remarkably piercing sight, which guarded treasures and devoured men. The Dragons of mediæval artists were frightful and fantastic beings, one half Bat and the other half quadruped or Serpent. The little Saurians which now bear the once dreaded name are no less interesting, although they are no longer monsters; they are distinguished from all other reptiles by a kind of wing, which is a large fold of skin, or membrane, on each side of the body. These wings are entirely independent of the other members, being sustained by six false ribs, which do not surround the abdomen, but rather extend horizontally. They are the only existing examples of our day of that organic arrangement which distinguished the reptiles known under the name of Pterodactyli, and which belonged to the jurassique period of geology.
Dr. Gray divides the Draconina into three genera, namely:—
I. Dracos, having the ears naked, nostrils below the fore ridge, of which three species are described—viz., D. volans, the Flying Lizard (Fig. 30), having the scales of the back broad, generally smooth, those of the throat granular; wings grey, fulvous, or brown, spotted and marbled with black, sometimes forming four or five oblique black bands near the outer edge; the sides with a series of large keeled scales: the Timor Flying Lizard, D. viridis Timorensis of Schlegel; and the Fringed Flying Lizard, D. fimbriatus, keeled.
II. Draconella, of which there are two species, one D. Dussumieri, having the nape crested; and D. hæmatopogon, the Red-throated Dragon, without crest on the nape.
III. Dracunculus, of which five species are described—namely, D. quinquefasciatus, the Banded Flying Lizard, nape not crested, having a longitudinal fold; D. lineatus, having the nape crested, the ears slightly concave; D. ornatus, wings grey, reticulated with black, and having broad black bands at the edge; the Spotted Winged Dragon, D. maculatus, grey, and the wings black spotted; and D. spilopterus, having the wing reddish near the body.] 134
This singular family of Saurians have the head wide and flattened, the mouth wide, the nostrils distant and lateral, the eyes large, with short lids; the tongue short, fleshy, and capable of slight elongation. The body is thick and short, low on the legs, rather squat and depressed, with a belly trailing on the ground; back without crest. The skin is defended by granular scales, interlaced with others of a tubercular character; they are almost always of a sombre colour. Their feet are short, wide apart, and robust; they are furnished on the upper part with imbricated laminæ, which enable them to adhere firmly to the surface of even the smoothest bodies, and to run with rapidity in all directions on a plain surface, and even to remain stationary with the back downwards, like the common house Fly. More generally, however, their hooked and retractile claws, like those of cats, assist them in climbing, crawling up trees, rocks, and even perpendicular walls, and to remain there immovable for several hours. Their flexible bodies mould themselves into the depressions of the surface of the earth, in which they become scarcely visible, their natural colour blending, and being confounded with, the colour of the soil. Their eye-balls, which dilate and contract considerably, protect them from the action of the sun's rays, and enable them, it is thought, to see in the dark. They are nocturnal, avoid the sun's rays, and catch their food in the chinks of rocks. Their movements are rapid, silent, and sudden. They hibernate, and are provided with fatty masses in the groin which are supposed to be a provision for their nourishment during that period. Geckos emit sounds which resemble the noise an equestrian makes when he would encourage his horse—smacking their tongues on the palate to produce the sound. They seek habitations in which they can find food, and are timid, inoffensive, and quite incapable of inflicting injury either by their bite or claws; but their repulsive appearance makes them objects of general repugnance, and has caused evil properties to be attributed to them. Thus people try to destroy them by every possible means. There are about sixteen known species of Geckos distributed in all quarters of the globe, but chiefly in warm countries. 135
[The Geckotidæ are divided into many genera, according to the construction of the toes. Duméril refers to the comparative shortness and general structure of the feet and conformation of the toes, which he describes and figures in detail. The lower surface and the sole he states are very dilatable, and furnished with small plates or lamellæ, following or overlying each other in a mode which varies in the different species. The nails are sometimes wanting on all the toes, but more frequently hooked, and more or less retractile; the toes sometimes united at the base, and in Platydactylus the extremity of the toe expands into a fan shape, as in the Tree Frogs. The membranous and soft plates of the lower surface of the toes have various modifications in different genera, which have been made the basis of their arrangement. The Wall Gecko is supposed by Gesner to be the Lizard spoken of by Aristophanes and Theophrastus, and the Tarentula of the Italians: and there is little doubt that it was the Αακαλαβωνμε of Aristotle and the ancient Greeks; it clambered about their walls catching spiders, on which it fed. Schneider has shown it was the Stellio of Pliny. Linnæus mentions three species, which he places with his great genus Lacerta. Modern herpetologists, following Cuvier and Duméril, class them according to the structure under the several genera Ascalabotes, Platydactylus, Hemidactylus, 136 Ptyodactylus, Thecadactylus, Stenodactylus, and Gymnodactylus.]
The Wall Gecko (P. homalocephalus), Fig. 31, is of an ashy grey colour, as if powdered on the upper part of the body. It is white underneath, and inhabits the islands of the Mediterranean, as well as the countries which form the basin of that sea, such as Italy, France, Spain, and Africa. They are generally found in old walls; they are, however, sometimes seen running on those of modern habitations. They feed on all sorts of insects, particularly on the dipterous insects and Arachnidans.
The genus Chameleo, of which ten species are described in the British Museum Catalogue, are natives of Africa and Asia and naturalised in Southern Europe. They live on trees, clinging to the branches by their feet and prehensile tails; they move slowly and with great caution, feeding upon insects, which they catch with singular dexterity by the rapid elongation of their tongue, which is viscid at the tip.
Certain groundless metaphors, deeply rooted in the popular mind, have singularly distorted the truth in respect to these reptiles. It is commonly believed that the Chameleon often changes its shape, that it has no fixed colour belonging to itself, but takes that of all objects which it approaches. This singular idea has descended from very ancient times. According to the reports of Theophrastus and Plutarch, the Chameleon takes all colours in turn but white; according to Aristotle it changes colour all over the body; but Ælian seems to have had views more in accordance with those of modern observers, for he says when it takes other colours than grey and disguises itself, it covers only certain parts of the body with them. Altogether the ancients made the Chameleon a very fantastic animal; hence in the familiar comparisons of literature these fabulous beings serve as a type to designate uncertain principles; to paint fawning men, who have neither character nor individuality of their own, but who bend themselves to the will and adopt the opinions of others. Putting aside the imaginary attributes accorded to the Chameleon by the fancies of the ancients, and painting them such as they are, we 137 still see in them animals most worthy of observation and highly interesting to the naturalist, as well for the singular formation of different parts of their bodies as for their remarkable habits, and even for peculiarities which have given some sanction to the errors and prejudices to which we have alluded.
Chameleons have compressed bodies; the back round and projecting, or rather pyramidal; the skin granulated; the head angular, with salient occiput resting on a short and thick neck; their legs are slender; the hind, as well as the fore toes are five; the tail prehensile and round. The eyes are very large and protruding, their globes covered by a single shagreen-like eyelid, which the animal can dilate or contract at will, but which leaves little liberty to a small hole pierced at the centre, through which a quick and rather brilliant eye-ball is perceived. The eyes, in the Chameleon, are thus completely enveloped, as if they were too delicate to sustain any glaring light; but this is not all—their eyes have a singular mobility. By certain special muscular arrangements they have the power to direct them on objects either together or separate. Sometimes they turn their eyes in such a manner that one eye looks back and the other forward. With one eye they can see objects above them, while with the other they can see those situated below. It is a common saying in France, applied to the Chameleon, "that it could look into Champagne and see Picardy in flames."
The vermiform and retractile tongue is also a most singular organ. It is cylindrical, about six inches long, terminating in a fleshy, dilatable, and somewhat tubular tip, which is covered with a glutinous secretion, by the aid of which it seizes its insect food, and draws it towards its mouth. The feet have five very long and almost equal strong and hooked claws, but the skin of the legs extends to the end of these toes, and unites them in a very peculiar manner. Not only is this skin attached to each of the toes, but it envelops them, and forms, as it were, two bundles,—the one of three fingers, and the other of two. From this structure one can anticipate the extreme difference which exists between the habits of Chameleons and those of Lizards. These two bundles of long toes are placed in such a manner as to enable them to seize the branches easily on which 138 they love to perch; they can grasp these branches by holding on with one bundle of fingers before, and the other behind, in the same manner as Woodpeckers, Cuckoos, and Parrots. Chameleons are better able to preserve their equilibrium upon trees than upon the ground; consequently they are more often seen in those ærial domiciles. Besides, their long and strong prehensile tail serves them as a fifth limb. They swing themselves about like monkeys, grasping the small branches, and thus saving themselves from falling. Moreover, they are cautious, moving at all times very slowly when going from one branch to another. Walking becomes much more difficult for them when they rest upon a level surface—groping their way as they advance, placing their feet upon the earth, one after the other, with the greatest circumspection. They also steady themselves on the ground by the aid of their tail. In their walk they display a certain gravity which contrasts with their diminutive size and the agility which might be expected from them. Even when perched upon a tree their movements exhibit a slowness and deliberation that one would be inclined to say was affected. It is true that the arrangement of their eyes, and the rapid movements of their tongue, render personal activity superfluous in their search for food. They can see their prey and their enemies from a great distance, and in all directions. The latter they readily avoid. As to their prey, when about to seize it, the Chameleon rolls round its extraordinary eye-balls so as to bring them to bear on the devoted object. As soon as it arrives within range of the tongue, that organ is projected with unerring precision, returning into the mouth with the prey adhering to the viscous tip. This tongue they can extend to a length sometimes surpassing that of their body. The skin of the Chameleon does not adhere to the muscles everywhere; some spaces are left free, into which the air penetrates, causing the skin to heave and swell; this mechanism is voluntary, the animal having the power of inflating or relaxing it at pleasure. When this great living bladder is emptied, the animal may be said to resemble a bag of gold-beaters' skin filled with bones. Chameleons exhibit great variation in their colours; that is to say, they may be almost white, sometimes yellowish, at other times green, reddish, and 139 even black, either in portions, or all over their bodies. These changes of colour were for a long time attributed to the greater or less distention of the vast lungs they possess, and to the corresponding modifications in the quantity of blood sent to the skin; but this explanation is now abandoned. According to Mr. Milne Edwards, the cause of these variations of colour lie in the peculiar structure of their skin, in which there exists two layers of membranous pigment, placed the one above the other, but disposed in such a manner as to appear simultaneously under the cuticle, and at other times so that the one hides the other. Again, occasionally the cuticle is hidden under the superficial pigment.
[Sixteen or seventeen species of Chameleon are described in the British Museum Catalogue.
I. Having an erect fin on the back, the belly crested; which includes the Fringed Chameleon, C. cristatus, a native of Fernando Po.
II. Having the back high, and compressed belly and sides, with a toothed crest; including the Side-crested Chameleon, C. laterales, a native of Madagascar.
III. The back and belly having a toothed crest, the sides simple, the scales small and equal, muzzle simple; including the Common Chameleon, C. vulgaris, with many synonyms. It is a native of the East Indies, is the recognised type of the family (Fig. 32), and the one most commonly brought to England. There are probably two varieties,—one from North Africa, which is also found in Sicily and the South of Spain; the other, the East Indian variety—C. Senegalensis, the Senegal Chameleon, a native of West Africa; C. arpelis, from Ashantee and Gaboon; C. verrucosus, a native of Bourbon and Madagascar; the Rhinoceros Chameleon, C. rhinoceroceratus, also from Madagascar.
IV. Having a toothed crest on the back, with the belly and sides simple, the chin and muzzle simple; including C. tuberculiferus, a native of South Africa; C. cucullatus, the Hooded Chameleon, a native of Madagascar; C. nasutus, having the chin simple, and the muzzle compressed, and C. bifurcus, having the muzzle in the male forked—both natives of Madagascar; C. 140 Tigris, Seychille Islands; C. ventralis, from South Africa, and C. pumilus, from the Cape of Good Hope.
V. Having back and belly without crest; including C. Parsonii, a native of Madagascar; and C. Owenii, the Three-horned Chameleon, from Fernando Po, and C. Brookesianus, an adult species, from S. W. Brookes's collection.
Have the head large, covered with a thick skin, ears closed with two valves, gape very wide, tongue short, jaws with a single series of cone-shaped teeth inserted in sockets; back with a hard disc formed of a longitudinal series of square keeled plates of hard bony consistence embedded in the skin; the under surface covered with smooth thin square plates; legs short, feet webbed, with four to five toes, the three inner toes of each foot only armed with claws.
They are divided into two groups:—
I. Crocodilidæ, having the lower canines fitting into a notch in the edge of the upper jaw.
II. Alligatoridæ, having the canines fitting into a pit in the upper jaw.] 141
The Shielded Saurians, as Duméril designates the largest of living species of that order of reptiles, have the body depressed, elongated, and protected on the back with a solid carinated shield or buckler; the tail longer than the trunk, compressed laterally, annulated and crested above; having four very short feet; the toes of the posterior feet united, or web-footed, each foot having three claws only; head depressed and elongated into a muzzle; the gape of the mouth extending back beyond the skull; tongue fleshy, adherent; teeth conical, simple, hollowed at the base or towards the root, unequal in length, and in a single row. Such is a brief summary of the family by Duméril and Bibron.
If the Eagle is the king of the air, the Tiger and the Lion the tyrants of the forests, and the Whale the monarch of the deep, the Crocodile has for the exercise of his undisputed control the maritime shores of tropical seas and the borders of tropical rivers. Living on the confines of land and water, this formidable reptile is at all times the scourge of those human beings who are compelled to reside near its haunts. Much larger than the Tiger, Lion, or Eagle, the Crocodile surpasses all terrestrial animals, with the exception of the Elephant, Hippopotamus, and some Serpents, in its power of destruction.
Crocodiles have the head depressed and elongated into a muzzle, in the front of which the nostrils are seen close to a fleshy tubercule, and furnished with movable valves. The mouth opens up to the ears; the jaws are of commensurate length, and are armed, as we have seen, with conical-pointed teeth, bent back, and disposed in such a manner that when the mouth is closed they pass one under the other. These teeth are implanted in a single row, and continually maintained in a good condition by an organic system which ensures their immediate reparation. In short, each tooth is hollowed at the base in such a manner as to form the cell or sheath of another tooth of a larger calibre. The new tooth, which presses on, exercises a sort of absorption upon the base of the old hollow tooth, so that the first is developed while the second is decaying. In some species the front teeth of the lower jaw are so long and 142 sharp that they perforate the edge of the upper jaw and appear above the muzzle when the mouth is closed. The lower jaw alone is movable, and that only in a downward movement. The mouth is without lips, consequently, whether walking or swimming, the teeth of Crocodiles are always visible.
This formidable conformation gives to the Crocodile an aspect at once terrible and alarming, which is increased by two wicked-looking eyes placed obliquely and close together, surmounted by a kind of eyebrow. The tail of these animals is very long, as thick as the body at the junction, and in shape it is flat, like an oar; this enables them to steer through the water like a fish, and to swim with rapidity. They have four short legs, of which the hinder have toes, united by a natatory membrane, and only three claws to each foot. The skin is coriaceous, thick, and resistant; being also protected by very thick knots intermingled with plates of different size, according to the parts of the body they protect. On the skull and face the skin adheres closely to the bone, and there is no trace of scales.
Nature has provided for the safety of these animals by covering them with a cuirass, the resistance of which is proof against almost everything. Thus the scales which defend the back and the upper part of the tail are square, and form hard transversal bands possessed of great flexibility, which prevents them from breaking. Down the centre of the back there is a hard crest, which adds to the strength of their armour. This cuirass is in many points proof against a bullet from a gun. The plates which cover the belly, the upper part of the head, neck, tail, and legs are also arranged in transversal bands, but less hard, and without crests. It is at these weaker and consequently vulnerable parts that those inhabitants of the waters which are enemies to Crocodiles manage to attack them successfully.
The general colour of the Crocodile is a dullish brown, with sometimes a shade of green along the back; the head and the sides are marked with green, or at least they have a greenish tint, with blackish spots; the under part of the legs and belly are of a yellowish grey. All these shades, however, vary with age and sex, and the nature of the water in which the animals live. 143
Crocodiles are oviparous, and their eggs are provided with resistant shells. These eggs are deposited by the female in some secluded place in the sand on the banks of the river, and are hatched simply by the ambient heat, without any assistance from the mother. The female Crocodiles of the Nile deposit their eggs where the solar heat soon brings them to maturity. In certain countries, such as the neighbourhood of Cayenne and Surinam, the eggs are buried under a kind of mound which the Alligators raise in damp places by gathering together leaves and herbaceous stems. This vegetable debris undergoes a kind of fermentation, the result of which is an increase of temperature, which, joined to that of the atmosphere, produces the desired result.
Lacépède describes an egg in the Museum of Natural History in Paris, which was laid by a Crocodile fourteen feet in length, which was killed in Upper Egypt. This egg is only two inches and five lines in its greatest diameter; in its least diameter it is one inch and eleven lines. It is oval and whitish. Its shell is cretaceous in substance, like the eggs of birds, but not so hard. At the time of their birth the little Crocodiles are only about six inches in length, but their growth is very rapid. They abound in large rivers in the tropics, and in marshy places near their banks. They often come on shore, for they are amphibious. In the night they watch for their prey. They feed exclusively on flesh—that is to say on fish, small Mammalians, aquatic birds, and reptiles. When they have seized a large object they drag it under the water, where it soon dies by asphyxia; there they leave it to macerate, when they eat it by instalments. In this manner men are sometimes carried away by Crocodiles, but it is contrary to the habits of the animal to suppose that they are devoured immediately. When a Crocodile has succeeded in seizing a negro, it does not devour him till the body becomes decomposed, when it can tear it to pieces with greater facility.
From the general structure of their bony framework it is difficult for Crocodiles to turn round or move otherwise than forward. This circumstance renders it easy to escape their pursuit. When chased by a Crocodile, it can be avoided by describing a circle, or running in a succession of curves. Upon the banks 144 145 of the Lake of Nicaragua, in America, an Englishman was once pursued by an Alligator which had surprised him when on its margin. The animal was gaining upon him rapidly, when some Spaniards who witnessed the scene cried out to him to run round it. Thus fortunately warned the pursued dodged the Alligator, and escaped from his dangerous enemy (Fig. 33).
[No specimens of the Crocodilidæ have been found in Europe, and until very recently none had been found in Australia, but they are very common in the new colony of Queensland, an Alligator twenty feet long having been shot on the banks of the Mackenzie river, which was afterwards exhibited at Rockhampton. Crocodiles, properly so called, are found in Africa, Asia, and America. The Gavials seem to be limited to the Ganges and other large rivers in India. Besides the Gavial, Asia produces three other species, namely, C. vulgaris, C. galeatus, and C. bifurcatus. Of the first, Siam is the chief locality; the others are found in the rivers which debouch into the Indian Ocean and the Ganges.
Include the Jacares, Alligators, and Caimans.
The Jacares have the head oblong and depressed, with a ridge across the face in front of the eyes; teeth unequal, canines of the lower jaw fitting into a pit in the upper jaw; toes only partially webbed, eyelids fleshy, nostrils separated by a cartilage. Five species are described—namely, J. fissipes, from Tropical America, six feet in length; J. sclerops, from the Brazils; J. Nigra, also from the Brazils; J. punctulatus, with triangular oblong head, muzzle elongated, thin and flat, with a rounded point in front, and a slight enlargement behind the nostrils; J. vallefrons, differing slightly from the above—both natives of the Brazils.
Alligators have the jaws oblong, much depressed, broad and nearly parallel; forehead with a small longitudinal ridge between the orbits; feet fringed, toes half webbed, the outer toes free; nostrils separated by a bony septum rising from the upper edge, muzzle lengthening with age. One species only is known, which is a native of North America; it attains a length of six to seven feet, and is known also as Crocodilus Mississipensis. 146
The Caimans have the jaws oblong, depressed, rounded, and swollen at the end, without frontal ridges or maxillary pits; teeth unequal, the lower canines fitting into pits in the upper jaw; toes webbed. There are three species described—C. trigonatus, C. palpebrosus, and C. goddeceps, all natives of Tropical America.
The Jacares, Alligators, and Caimans are natives of America, which country is fruitful in other species of the family. C. acutus is also found in Martinique and San Domingo; C. rhombifor, at Cuba; A. palpebrosus, A. sclerops, A. punctulatus, and A. cynocephalus are natives of the southern part of the American Continent; and A. lucius is found in the north.]
The principal characteristics of the American Crocodile are a head one-third its length, and a very short muzzle; teeth unequal in shape and size, the fourth lower tooth being buried in the upper jaw when the mouth is closed; the first teeth of the lower jaw piercing the upper at a certain age, so as to appear through the muzzle when closed. The hinder legs and feet rounded, having neither crest nor indentation on their edges; the intervals of the toes more than half covered with a short membrane, forming semi-palmated feet.
It is generally admitted, as we have stated above, that there are five species of this genera, all exclusively American, the type of which is the Alligator, or Caiman. A. Mississipensis (Gray) belongs properly to North America, through the whole southern extent of which it is found. They are gregarious, living together in large herds in the Mississippi and its southern tributaries; they are also found in the lakes and marshes of Louisiana, Carolina, and even as far north as thirty degrees of north latitude. Alligators do not appear to leave fresh water. During the winter season they bury themselves in the mud of the marshes, and await in a state of torpor the return of spring, which is the signal of their restoration to activity. In the neighbourhood of Bayou Sarah, on the Mississippi, flats of lakes and marshes stretch away to a vast extent on either bank; every year these reservoirs are flooded by the overflow of the river, when they are visited by myriads of fishes. The heat soon partly dries up these lakes, leaving only about two feet deep of water, thus displaying a vast amount of prey ready prepared for 147 the shore birds and Crocodiles. Millions of ibis, herons, cranes, and cormorants wade into the water in pursuit of these fish. In the deepest portions vast quantities of these imprisoned fish accumulate, and these parts are known in the country as the Alligators' holes. Thither these reptiles crowd, pressing one against the other, and they soon thoroughly clear it of the fish which lately were in such dense crowds. As evaporation proceeds and the marshes gradually dry up, the fish are more and more exposed to their voracious enemies. The Alligators pursue and devour them in the water, whilst the ibis destroys those which seek the banks for refuge. Alligators fish chiefly during the night. In the hours of darkness and obscurity they assemble in large herds, chase the fish before them, driving them into some retired creek, where they rejoice their hearts at the expense of the unfortunate finny tribes, which they force into their widely opened mouths by a lateral movement of their tails. On these occasions the clashing of their jaws may be heard at the distance of a mile. Alligators are found by thousands in Mexican waters, and nearly all North American rivers to the south of them. In the beautiful transparent waters of Lake Claro they abound, and are without difficulty seen by the naked human eye. Here they are so closely pressed one against the other that they resemble a raft of trees recently felled, and the resemblance is further increased by the colour of their backs and the bark of a newly-felled tree being identical. In this united and immovable condition, while waiting for their prey, the approach of a boat is disregarded; but they rush with avidity at everything animate which either falls or is thrown into the lake. Many children of poor negro women become a prey to the Caiman in this locality. They rarely, however, pursue men, yet they would not hesitate to devour them if their imprudence has placed them close to their terrible jaws.
The natives of Mexico hunt the Caiman. When they meet an isolated individual asleep, they throw a lasso round its body, and when secured, gag it. After this operation, the victim's career is terminated by hammering on his head. There is another means which the Indians use to capture the Caiman. They provide themselves with four pieces of hard wood about a foot long, and as thick as a man's finger, and pointed at each end; round these they tie 148 a cord in such a manner that, supposing the cord to be an arrow, the four sticks would form the head of it. They then fasten the other end of the cord round a tree, and bait with meat. This device is thrown into the water. When the Caiman snaps at the prey the points of the hook, on straining on the line, penetrate into its flesh. Having waited till the Alligator is dead, it is drawn from the water, when the captors further gratify their dislike and spirit of revenge by breaking its skull with stones and sticks.
Another method of capturing Alligators is practised by the residents on the upper waters of the giant river Orinoco. A tree is bent (generally a bamboo is selected from its elasticity) till the top is brought down to the butt, a bait is then placed on a sharp hook, the line attached to it being fastened securely to the small end of the bent tree, which is caused to relax its position by an ingenious piece of mechanism which gives way the moment the least strain is felt upon the line; the tree-point becoming thus released, straightens itself with great velocity, and drags the victim from the water.
Frequently the Alligator, from constant pursuit and interruption, becomes excessively wary and difficult to destroy; when such is the case, a live bait is sometimes successfully employed. For instance, a Dog with a hook tied to his back is taken in a canoe and dropped in the water; it is seldom the unfortunate cur is permitted to swim far before being seized.
It is currently believed that the Alligator prefers dog-flesh to all others. The negroes on the plantations in the South-Western States of America, by imitating the barking of a dog, frequently lure these reptiles from their hiding-places, when a well-directed bullet terminates their career.
Alligators are very voracious, but, like Serpents and Turtles, they can live a long time without nourishment. In Brown's "Natural History of Jamaica," he asserts that he has known the Caiman to live several months without food. The following experiments have been tried in that island:—The mouth of an Alligator was muzzled by a strong cord, it was then thrown into a reservoir of water. Thus these animals lived a considerable time. They were seen to rise occasionally to the surface of the water, until death came to their rescue. Let us add to 149 this, that Crocodiles bred in captivity in the menagerie of the Museum of Natural History, at Paris, sometimes live for several months without eating.
The female Alligator takes more care of her young than the female Crocodile, properly so called. She conducts them to the water, and in the slimy mud she disgorges her half-digested food for their nourishment.
The true Crocodiles are indigenous to Africa, but they are found also in Manilla and India. Their length of head is almost double its breadth. The fourth tooth of the lower jaw is the longest and largest of all, and passes into an indentation hollowed out in the edge of the upper jaw, becoming visible on the outside. The hind feet have on their external edge a dentated crest, and the interstices of their toes, externally, are palmated.
The principal type is the Common Crocodile, C. vulgaris, which sometimes attains the length of nine or ten feet. The upper part of the body of these reptiles is of an olive green colour spotted with 150 black, and marbled upon the head and neck with the same colour, also the back and tail; two or three broad, oblique black bands are visible upon the flanks of the under part of the body, which is of a yellowish green. Crocodiles abound in Africa. Formerly they were found in all parts of the Nile, but lately it is said that C. vulgaris is no longer to be met with in the Delta, but that it exists in great numbers in the Thebaid and in the Upper Nile. They are also found in the rivers Senegal and Niger, in Caffraria, and in Madagascar. Most authors give them the name of Crocodiles of the Nile. This species are found also in India.
The Crocodile was considered a sacred animal by the ancient Egyptians. In ruins of temples mummies of Crocodiles are still found in a perfect state of preservation. The Romans introduced living Crocodiles at the national games in the Colosseum. At first only five were imported under the ædileship of Scaurus. Under the Emperor Augustus thirty-six were killed in the Circus of Flaminius. Several ancient medals represent this reptile, the body of which perfectly resembles that which now lives in the waters and on the banks of the Nile. There is a truly wonderful fact in the natural history of the Crocodile. Listen to what Herodotus, the father of history, tells us with regard to it:—"When the Crocodile takes his food in the Nile, the interior of its mouth is always covered with bdella (flies). All birds, with one single exception, flee from the Crocodile; but this one, the Nile Bird, Trochylus, far from avoiding it, flies towards the reptile with the greatest eagerness, and renders it a very essential service. Every time the Crocodile goes on shore to sleep, and at the moment when it lies extended with open jaws, the Nile Bird enters the mouth of the terrible animal and delivers it from the bdella which it finds there; the Crocodile shows its recognition of the service, and never harms the bird."
This fact, reported by Herodotus, was long considered to be a fable, but the naturalist, Etienne Geoffroy Saint-Hilaire, who formed part of the commission that General Bonaparte took with him in his expedition into Egypt, had on several occasions opportunities of proving the truth of the historian's narrative.
In a memoir read to the Academy of Science on the 28th of January, 1828, he says, "It is perfectly true that there 151 exists a little bird which flies about, perpetually seeking, even in the mouth of the Crocodile, the insects which form the principal part of its nourishment." This bird, which Geoffroy Saint-Hilaire recognised as the Charadrius Ægyptius of ornithologists, is like a Plover. The bdella, which thus torment the Crocodiles, and even excite them to madness, are no other than our European gnats. Myriads of these insects haunt the banks of the Nile, and when these giants of its waters repose on its margin, warming themselves in the sun, they become the prey of these insignificant pigmies. It is like the war between the Lion and the Mouse, described by La Fontaine. The bdella fly into the Crocodiles' mouths in such numbers that they cover the entire surface of the palate, and form a brownish crust. These little pests pierce the tongues of the reptiles with their stings. It is then that this bird comes into the mouth of the monster to catch them, and deliver it from such innumerable enemies. The Crocodile with one bite could easily destroy the bird, but he knows too well what he owes to this friend to do it an injury. Crocodiles of the Nile are more voracious than the American Alligators. Hasselquist asserts that in Upper Egypt they often devour women who come to draw water from the Nile, as well as children playing upon its banks. Geoffroy Saint-Hilaire says, that in the Thebaid they often met with Arabs wanting an arm or leg, who accused Crocodiles of this mutilation. Sir Samuel Baker also mentions, in his late work on the Nile and its tributaries, the desire of these amphibia for human flesh, and the dread they are held in by the natives. Livingstone, the celebrated traveller, gives the following account of an encounter he had with one of these ferocious animals:—
"The Crocodile," says the celebrated traveller, "makes many victims every year among the children who are so imprudent as to play on the banks of the Liambia when their mothers go to fetch water. The Crocodile stupefies its victim with a blow from its tail, then drags it into the river, where it is soon drowned. In general, when the Crocodile perceives a Man it dives, and furtively glides away from the side which he occupies. Sometimes, on the other hand, it precipitates itself with surprising agility towards the person it has discovered, which may be noticed from the disturbance 152 caused on the surface of the water. An Antelope which is being hunted and takes to the water, in the lagunes of the Barotsé valley, a Man or a Dog who goes there to seek for game, will scarcely fail to be seized by a Crocodile, of whose presence he has not the slightest suspicion. It often happens that, after having danced in the moonlight, the young natives of the river's bank will often plunge into the water in order to refresh themselves, when, being seized by an Alligator, they perish."
[This mode of attack (striking with the tail) is also one of the methods adopted by the Alligator of America for disabling its prey. A friend, on whose veracity I have much dependence, while shooting wild fowl on one of the tributaries of the Lower Mississippi, had the fortune to witness a fight between a Bear and an Alligator. He was called to the scene of the struggle by the noise made by the combatants, in the dry cane, that yielded to their pressure as they fought in each other's embrace. Several times both ceased only to recover breath and fresh energy; at length the Alligator missed striking the foe with its tail, Bruin seized the opportunity, and with all his efforts succeeded in turning the amphibian on its back, where he held him for some minutes, at the same time gnawing one of the fore-shoulders. A final struggle of the now worsted Alligator hurled both into the water, where they disappeared, the disturbed surface telling of the dreadful contest that was being prolonged beneath; after the lapse of over a minute the Bear came up, evidently much fatigued, and swam ashore, my friend forbearing to wound, or possibly kill, the gallant conqueror.]
Crocodiles, it is said, which have never eaten human flesh, are much less dangerous than those that have acquired a taste for it. Mr. Combes states that he was assured by an inhabitant of Khartoum, who had reached the town with the Egyptian troops—that is to say, before the horrors committed by the Desterdar, acting with Mehemet Bey, who had been Governor of the Soudan some time before Mr. Combes's voyage—that the Crocodiles appeared to be quite indifferent to human flesh; but after the many executions by drowning ordered by Mehemet Bey, as he was told by a native whom he interrogated—"since the Nile has been loaded with the carcasses of my brethren"—the monsters which inhabit it have 153 become habituated to substantial food, which they scarcely knew before: so that afterwards those swimming in the river, or even bathing on its banks, were exposed to imminent danger.
Natives of Africa shoot the Crocodile with a gun, or attack it with a barbed javelin, which is thrown by hand, and aimed at the fore-shoulder. Some Egyptians are reported to be daring enough to swim under the Crocodile, and pierce him in the belly with a dagger. The negroes of Senegal are said to be equally expert. If they surprise the animals in parts of the river where there is not sufficient water for them to swim, they attack the monster with a lance; and with their left arm wrapped in a sheet of leather, they commence by aiming with their weapon at the eyes and throat; then they thrust the arm, encased in leather, into its mouth, and, holding it open, their enemy is either suffocated or expires under the wounds received. Traps are also employed successfully for their destruction. In Egypt the natives dig a deep hole in the ordinary route of the Crocodiles, which is easily discovered by the trail they leave in the sand. This hole is covered with branches and strewed with earth. The Crocodile is now alarmed with loud cries, which disturb and drive him back to the river, by the same way that it has left it. As it passes over the treacherous hole it falls in, when it is killed, often with the most brutal cruelty. At other times a thick cord is attached to a large tree, and to the other end of the cord a lamb is bound, held by a protruding hook. The cries of the lamb attract the Crocodile, which, in its attempt to carry off the bait, is taken by the hook.
Still another method for the destruction of these repulsive-looking creatures has been adopted on one or two occasions by our countrymen in India. A dead animal is procured, in its abdomen is placed a loaded shell, to which is attached a wire made fast to an electric battery; when the bait has been seized and carried to the bottom, the shell is exploded, which invariably maims or kills the Crocodile.
The Gavials, or Indian Crocodiles, have long narrow cylindrical muzzles, slightly inflated at the extremity; the teeth are almost the same, both in number and shape, on each jaw, the two first and the fourth of the lower jaw pass into notches or indentations 154 in the upper jaw, and not into holes, as in Crocodiles; the hind legs are dentated and palmated, like those of African Crocodiles. The Gavials are chiefly remarkable for their long head, its type being the Gavial of the Ganges, or Gavial longirostre. It is of a deep watery green colour, having on the upper part numerous irregular brown spots; in the young, the back and limbs are transversely banded with black; the lower part is of a pale whitish yellow; the jaws are marked with brown, the claws are of a clear horn colour. This species is not so carnivorous as the others, and is consequently less dreaded.
The Gavial of the Ganges, G. Gangeticus, is supposed to be the largest of the existing Saurians; its length, as given by Duméril, is seventeen feet four inches. 155
["The body," as described by Dr. Gray, "is covered with square imbedded plates, generally forming a dorsal and ventral shield united by their margins, leaving only the head, neck, limbs, and tail free, and (in some species, as the Box-Tortoises, Cinasternon, shut up by movable closely-fitting doors) only covered with a scaly skin; the upper shield formed of the ribs united together and adherent to the dorsal vertebræ by a toothed suture, and surrounded by a series of bones forming the edge of the shields; the lower shield, or sternum, formed of four pairs and a central anterior bone; the jaws toothless, covered with a horny bill, rarely hid by fleshy lips; eyelids distinct; drum of the ear visible; legs short and thick; tail conical." "The natural dwelling chamber of the Chelonia consists chiefly," says Professor Owen, "and in the marine species (Chelone) and Mud Turtles (Trionyx) solely, of the floor and the roof; side-walls of variable extent are added to the fresh-water species (Emydians) and Land Tortoises (Testudinians). The whole consists of 'osseous plates,' with superincumbent horny plates, or 'scutes,' except in the Soft or Mud Turtles (Trionyx and Sphargis), in both of which these are wanting."—("Circle of the Sciences.")
These animals, to which a portable stronghold is thus given in compensation for inferior powers of locomotion and defence, are recognisable at a glance from the singular armour with which Nature has provided them. A double shield envelopes all parts of their bodies, only permitting the head, neck, legs, and 156 tail to pass through it: moreover, all these organs can be hidden within this double cuirass by means of a retractile power possessed by the animal. This double armour consists of a carapace, or back-piece, and plastron, or breast-plate, composed of a series of small bones or plates closely united together; the first resulting from the union of the sides and dorsal vertebræ, the plastron, or lower buckler, being only a highly-developed sternum. These organs are merely portions of the skeleton, which, in place of being lodged in the depths of the soft parts, has become the superficies, which is only covered by a thin, dry skin.
This numerous and highly-interesting order of Reptiles, called Chelonia, from χελωνη, a Tortoise, are also called Testudinata, from testudo, the Latin name for a Tortoise, from the double shield in which the bodies of all, whether terrestrial, fresh-water, or marine Tortoises, are enclosed.
The skeleton of the Tortoise is, perhaps, the most extraordinary structure with which we are acquainted. This oddly-organised animal when first seen strikes the beholder with astonishment. The carapace and plastron, with their connecting plates, form a sort of protecting box, in which the animal lives, its head and tail excepted. In the land Turtles the head and feet, which are comparatively senseless, can be withdrawn within the protecting armour. The ribs and sternum are both placed quite on the exterior of the body, so as to form a broad dorsal shield on the upper surface, and an equally strong ventral plate; between these, the limbs and the head can be more or less completely retracted. Nevertheless, the modifications in the arrangement of the elements by which these changes are accomplished are of the simplest nature. In the common Tortoise, Emys Europæus, the vertebræ of the neck and tail being connected together in the ordinary manner, the neck and caudal region of the spine present their usual flexibility, but the dorsal vertebræ are strangely distorted, the upper arch being disproportionately developed, while the bodies remain almost in a rudimentary state; the spinous processes of these vertebræ are flattened and converted into broad osseous plates, which form a longitudinal series along the centre of the back, and connected together by means of sutures. The ribs are changed into broad flat bones firmly united by sutures to each other, and also to the 157 lateral margins of the spinous processes of the vertebræ, so that they form together a single broad plate; the heads of the ribs are feebly developed, and the intervals between them and the bodies of the vertebræ filled up with ligament. The margin of the shield thus formed by the dorsal ribs is further enlarged by a third set of flat bones fixed by sutures around the whole circumference of the carapace.
The plastron, or ventral plate, is made up of nine pieces, of which eight are arranged in pairs; but the ninth, which is always placed between the four pieces composing the two anterior pairs, is single, and occupies the mesial line. The bones of the shoulder and hip are placed within the thorax, and articulated to the sides of the vertebral column.
Of this vertebral column in these extraordinary animals, Professor Owen remarks that the manifold modifications of the framework which render it a portable abode, appear to have been given as a compensation for inferior powers of locomotion, and the absence of offensive weapons. But with all its modifications, the same number of pieces are found in the bony skeleton as in other ordinary vertebratæ, the form and volume of many of these pieces being alone changed.
The skin which covers the body of these animals sometimes preserves its softness, being altogether devoid of scales; but in nearly all the species it is covered with horny scales of great consistency. Upon the plastron and carapace these scales form large plates, the arrangements and appearances of which vary in different species, some of them being often remarkably beautiful. The material which bears the name of Tortoise-shell forms an important article of commerce.
Aristotle mentions three groups of Tortoises; namely, χελωη χερσαια, or Land Tortoises; θαλαττια, or Sea Tortoises; and Εωhυς, or Fresh-water Tortoises. Cuvier divides them into five sub-genera:—1, Land Tortoises, Testudo (Brogniart); 2, Fresh-water Tortoises, Emydes (Brogniart); 3, Marine Tortoises, Chelque (Cuvier); 4, Chelydes, Testudo fimbriata; 5, Soft Tortoises, Trionyx (Geoffrey)—in which he is followed by Dr. Gray in the British 158 Museum Catalogue, who makes them the third order of Reptiles in his arrangement as follows:—
I. Testudinidæ. |
---|
Testudo, Chersina, Kinixys, Pyxis. |
II. Emydidæ. |
Geoemyda, Emys, Cyclemys, Malaclemys, Cistudo, Kinosternon, Chelydra, Platysternum. |
III. Chelydidæ. |
Sternotherus, Pelomedusa, Hydraspis, Chelymys, Phrynops, Chelodina, Hydromedusa, Chelys, Peltocephalus, Padocnemis. |
IV. Trionycidæ. |
Trionyx, Emyda. |
V. Cheloniadæ. |
Sphargis, Chelonia, Caretta, Casuana. |
In the valuable "Erpétologie" of Messrs. Duméril and Bibron, the Chelonians are divided into—1, Land Tortoises, Chersites; 2, Marsh Tortoises, Elodites; 3, River Tortoises, Potamites; 4, Sea Tortoises, or Turtles, Thalassites.
This arrangement being the most simple, is adopted as best adapted to our purpose.]
Terrestrial Tortoises are distinguished by their short, oval, and convex bodies, covered by carapace and plastron; four feet, and the absence of teeth; short, stumpy, unshapely legs; nearly equal toes, armed with claws, united by a thick skin, so as to form a clumsy foot, the periphery of which forms a sort of hoof, which seems adapted for the land.
In this group the carapace is very convex, its height sometimes exceeding its breadth; it forms a solid, generally an immovable, arch, under which the animal can completely conceal its feet and tail. This buckler is covered with large horny plates or scales.
Land Tortoises have been known from the earliest times, representations of them being found on numerous monuments of antiquity, the product of ancient art. Moreover, ancient writers tell 159 us that the carapace of the Tortoise contributed its substance to the formation of the first lyre; it was consequently sacred to Mercury as the deity of music and inventor of that instrument.
The Land Tortoises are divided into four genera, which Duméril and Bibron again divide into three sub-genera and thirty species. The most interesting species, however, to which we must limit our remarks are—the Marginate Tortoise, Testudo marginato; the Moorish Tortoise, Testudo Mauritianica; the Greek Tortoise, Testudo Græca; and the Elephantine Tortoise, Testudo elephantina.
The Margined Tortoise, which was long confounded with the Greek Tortoise, is found abundantly throughout the Morea, in Egypt, and upon the Barbary coasts. The carapace is oval in form, oblong, convex, and much dilated at the posterior margin, and nearly horizontal; the plastron is movable behind, which is its chief sub-generic character; the tail is thick, conical, and scarcely issues from the carapace. The plates of the disc are of a blackish-brown, presenting towards the centre certain spots of a beautiful yellow colour; the marginal plates are habitually ornamented with two triangular spots, one yellow, the other black. The underpart of the body is of a dirty yellow, with one large triangular black spot upon six or eight of the sternal scales. This Tortoise is of medium size.
The Moorish Tortoise, Testudo Mauritianica, is commonly found in the neighbourhood of Algiers, and along the coast of Morocco, 160 whence those are sent which are sold in the Paris markets. When shooting in Morocco, scarcely a day would pass without the setters or pointers finding numbers of them, to which they would stand with as much staunchness as game. The scent they emit is so powerful as to be easily detected by a human being. The carapace of this species is also convex; the sternum is also movable behind: it is generally olive-coloured. The plates of the disc are marked with blackish spots, and sometimes with a buckle of the same colour, which covers their circumference on the front and sides. The plates of the plastron, the ground of which is olive, have each a large black spot in the centre. This species is rather smaller than the Marginate Tortoise.
The Greek Tortoise, Testudo Græca, is of small dimensions, scarcely exceeding twelve inches in length. They inhabit Greece, Italy, some of the Mediterranean isles, and the south of France, from whence it seems to have been transplanted into Italy. They feed upon herbs, roots, slugs, and lob-worms. Like all their race, they sleep during the winter, passing this season in holes which they excavate in the soil sometimes more than thirty inches deep. As the month of May approaches they issue from their retreat, resorting to some sheltered sandy place, where they bask themselves in the sun's rays. Towards the month of June the females lay from twelve to fourteen white spherical eggs, as large as a small walnut; they dispose these eggs in a hole exposed to the sun; but covered over with earth. Thus the operation of hatching is performed. The carapace of this species is oval and very much arched; their marginal plates are twenty-five in number; the plastron, which is almost as long as the carapace, is separated into two great portions by a longitudinal line; the plates of the carapace are spotted with black and greenish yellow, forming a large marbled pattern; the centre of the disc is besides relieved by a small, irregular, blackish, central spot. These three species are held in high estimation on account of their flesh, which gives an agreeable taste to soup.
The Elephantine Tortoise, Testudo elephantina, the length of which is more than three feet, inhabits most of the islands situated in the Mozambique Channel—namely, between the eastern coast of Africa and the Isle of Madagascar. The Museum 161 of Natural History at Paris had specimens of this Tortoise which lived more than twelve months, and which weighed about six hundred pounds. Their flesh is extremely delicate, and much sought after.
In some other Terrestrial Tortoises, from which the genus Pyxis has been formed, the anterior portion of the plastron is movable; and when the head and feet are drawn in, the animal can fasten itself against the sides of the carapace like a door in its case.
In some Terrestrial Tortoises, which have been formed into particular genera, the carapace is flexible, and can lower itself behind like the plastron; these are Kinixys. Lastly, there are others which, for legs, have only four unguiculated toes: such as the Homopodes.
Marsh Tortoises, Elodites, occupy a place between Terrestrial Tortoises and those which are essentially aquatic. They have the carapace more or less depressed, oval, and broader behind; their feet have distinct flexible toes supplied with hooked claws, of which the phalanges are united at the base by means of an elastic skin, which enables them to separate one from the other, at the same time preserving their strength and assisting them to grasp a much larger surface. Thus they can walk upon the ground, swim on the surface of deep waters, and climb up the banks of lakes or other tranquil waters, which are their habitual dwelling-places.
These Tortoises are generally of small size; being carnivorous, they feed upon small living animals. As they exhale a nauseous odour they are not used as an article of food; and further, as their carapace is neither thick enough nor beautiful enough to be manufactured as tortoise-shell, they are consequently little sought after. There are a hundred species of Elodians, or Marsh Tortoises, known, which are spread over all parts of the globe, but principally in warm and temperate regions. Such are the Cistudo, Emydes, and Trionyx.
The Elodians have none of the sluggishness of the Land Tortoises; they swim with facility, and on land they walk with considerable rapidity. Their eggs are white, and nearly spherical, with a calcareous shell, and these are deposited in a hollow dug in the soil 162 or sand, like the Land Tortoises, the place chosen being generally situated on the banks of some secluded stream; the number of eggs increasing as the animal approaches maturity.
The Elodians are divided into Cryptoderes and Pleuroderes: the former distinguished from the latter by the retractile power they possess of concealing their cylindrical neck, with its sheath of loose skin, under the middle of the carapace; the head, whose width is nearly equal to its height at the occiput; the eyes always lateral, and their orbit so large that the diameter of the cavity nearly equals a fourth of the whole cranium; and the jaws, which are strong, sometimes trenchant, in others are dentated on the edge. In the larger number of species the anterior extremity of the upper beak is notched with a strong tooth on each side, producing the appearance of a beak closely resembling that of birds of prey.
The Mud Tortoises, Cistudo, sometimes called the Yellow Tortoise (Fig. 36) are very abundant in Europe. They are found in Greece, Italy, Spain, Portugal, and in the southern provinces of France; also in Hungary, Germany, and as far north as Prussia. They inhabit lakes, marshes, and ponds, at the bottom of which they bury themselves in the mud. Occasionally they come to the surface of the water, and remain there for hours. They live principally upon insects, mollusks, aquatic worms, and small 163 fishes. Although the flesh of the Mud Tortoise is far from being palatable, it is nevertheless eaten in countries where they are common.
The Emydes are divided into four considerable groups, namely, the European group, of which Fig. 37, E. Caspica, is typical; the American group, containing twelve or fourteen species; the African Emys; and the Oriental group of twelve species. 164
The Pleuroderes have the neck retractile on one side of the carapace, without their having the power of drawing it between their fore feet, and under the buckler and plastron, like the Cryptoderes. Chelys matamata (Fig. 38) belongs to this division. This species lives in stagnant water, and is altogether remarkable for its singular appearance—for its depressed, wide, and triangular nostrils, prolonged into a proboscis; its wide gape, rounded jaws, and the cutaneous appendages to the chin. This is sometimes called the Bearded Tortoise.
The River Tortoises live constantly in the water, only coming to land occasionally; they swim with much ease below and on the surface. The carapace is very broad and flat; the toes united up to the claws by broad flexible membranes. These membranes change the feet into true paddles, which perform the office of oars. They seem to attain a considerable size, one kept by Pennant for three months weighing twenty pounds, its buckler not reckoned; the neck measuring twenty inches in length. The upper parts of their bodies vary in tint from brown to grey, with irregularly marbled, dotted, or ocellated spots; the underpart is a pale white, rosy, or purple tint. Sinuous brown, black, or yellow lines are symmetrically disposed on the right and left, principally on the neck and on the limbs.
During the night, when they think themselves safe, the River Tortoises seek repose on the rocks and islets, or on timber floating in the rivers, from which they plunge into the water on the slightest noise. These Tortoises, which accommodate themselves so perfectly to the medium that they inhabit, are continually at war with the fishes, reptiles, mollusks, and other denizens of the rivers. They are voracious and active, and are relentless enemies to the young of fishes, and especially of Crocodiles.
The carapace of the River Tortoise, Trionyx, is soft, covered with a flexible cartilaginous skin resting on a greatly-depressed osseous disk; its upper surface is covered with shrivelled sinuosities. As they are destitute of scales these Tortoises are said to be soft; their flesh is much esteemed, and they are angled for with hook and line, baited with small fishes or living worms and mollusks, or 165 with dead bait, to which the sportsman gives motion and apparent life, for they are said never to approach dead prey. When they seize their victim, or defend themselves, they dart out their head and long neck with great rapidity, biting sharply with their trenchant beak, and holding on till they have bitten out the piece. From this peculiarity they are commonly known in the United States as the Snapping Turtle. Persons wading have been known to lose toes from their bite.

Lesueur states that towards the beginning of May the females of Gymnopus spinifera, belonging to this division, seek out sunny sandy spots on the river's bank for the deposit of their eggs; they are not deterred from choosing steeps of ten or fifteen feet for this purpose. Their eggs are spherical, and more fragile than those of the Marsh Tortoise. They deposit from fifty to sixty at a time. None of this group are found in Europe. The fresh-water lakes and rivers of the warmer regions, such as the Nile and the Niger, in Africa, the Mississippi, the Ohio, and the 166 Amazon rivers, in America, the Euphrates and the Ganges, in Asia, are its habitats. Among other remarkable species in the group we here represent Trionyx Ægyptiacus, Fig. 39, supposed to be the Εμυς of Aristotle.
No modern naturalist has done more to illustrate the habits of the Fresh-water Turtle than Mr. Bates, in his highly interesting work, "The Naturalist on the Amazon." "The great Fresh-water Turtle (probably Platemys æfipes) of the Amazon or Solimoens grows on the upper river," he says, "to an immense size, a full-grown one measuring nearly three feet in length, by two in breadth, and is a load for the strongest Indian. Every house (in Ega) has a little pond called a corral, or pen in the back-yard, to hold a stock of these animals through the season of dearth—the wet months. Those who have a number of Indians in their employ send them out for weeks, when the waters are low, to collect a stock, and those who have not purchase their supply—this is attended with some difficulty however, as they are rarely offered for sale. The price of Turtles, like that of other articles of food, has risen greatly since the introduction of steam-vessels. Thus, when I arrived, in 1850, a middle-sized one could be bought for ninepence, but when I left, in 1859, they were with difficulty obtained for eight or nine shillings each. The abundance of Turtles varies with the amount of diurnal subsidence of the waters. When the river sinks less than the average, they are scarce; but when high waters have prevailed, they can be caught in abundance, their haunts being less restricted, and appropriate breeding-places more numerous.
"The flesh is very tender, palatable, and wholesome; but it is very cloying, and every one ends sooner or later by becoming thoroughly surfeited. I became so sick of Turtle in the course of two years that I could not bear the smell of it, although nothing else was to be had; consequently I suffered from actual hunger."
One of the most amusing sketches in Mr. Bates' book is a journey he made on the Solimoens, during which he visited the praias, or sand-islands, the Turtle-pools in the forests, and the by-streams and lakes of the great river. His companion was Cardozo, who was a sort of official superintendent of the diggers for Turtles' eggs on the sand-banks of Shimuni, the island lying nearest to Ega. 167 There are four or five of these Royal Praias, as they are called, in the district, each having its commandant, whose business is to see that every inhabitant has an equal chance in the egg-field.
"The pregnant Turtles descend from the interior pools of the main river in July and August, before the outlets dry up, and seek their favourite sand-island in countless swarms; for it is only a few praias that are selected by them out of the great number existing. When hatched, the young animals remain in the pools throughout the dry season; for these breeding-places of the Turtle then lie from twenty to thirty feet above the level of the river, and are accessible only by cutting a path through the dense forest." On the 26th of September Mr. Bates left Ega with his companion, who was about to visit the sentinels placed to mark when and where the Turtles laid their eggs. Their conveyance was a stoutly-built canoe, or igareté, arranged for two paddlers, with an arched covering in the stern, under which three persons could sleep pretty comfortably. The swift current of the Solimoens carried them rapidly to the large wooded island of Baria, which divides the river into two broad channels. Shimuni lies in the middle of the north-easterly passage. They were quickly paddled across, reaching it an hour before sunset. The island is about three miles long and half a mile broad. The forest which covers it rises to an immense uniform height, presenting all round a compact and impervious front, the uniformity being interrupted here and there by a singular tree, called Mulatto wood, whose polished dark-green trunk is seen conspicuously through the mass of vegetation. The sand-bank lies at the upper end of the island, and extends several miles, presenting an irregular surface of ridges and hollows. At the further shore to the north-east, where no forest line shuts out the view, the white, rolling, sandy plain stretches away to the horizon; to the south-west a channel, about a mile in breadth, separates Baria from Shimuni.
Arrived at this island, Mr. Bates proceeds to describe with great minuteness the operations of the Turtles, as well as those of the sentinels placed to watch them.
"We found two sentinels," he says, "lodged in a corner of the praia, where it commences at the foot of the towering forest west of the island, having built themselves a little rancho with poles 168 and palm-leaves. Great precautions are obliged to be taken to avoid disturbing the vigilant Turtles, which, previous to crawling ashore to lay, assemble in great shoals off the sand-bank. The men during this time take care not to show themselves, and they warn off any fisherman who attempts to pass near the place; for the passage of a boat, or the sight of a man, or a fire on the sand-bank, would prevent their laying their eggs that night, and if repeated, they would forsake the praia for some quieter place."
After a night spent under a temporary shed rapidly constructed for himself and companion, Mr. Bates rose from his hammock shivering with cold.
"Cardoza and the men were already watching the Turtles on a stage erected on a tall tree fifty feet high; from this watch-tower they are enabled to ascertain the place and date of successive deposits of eggs, and thus guide the commandant in fixing the time for his general invitation to the Ega people. The Turtles lay their eggs during the night, leaving the water in vast crowds when all around is quiet, when they crawl to the central and highest part of the praia. The hours between midnight and dawn are those when the Turtles excavate, with their broad, webbed paws, deep holes in the fine sand, the animal in each case making a pit about three feet deep; in this pit it lays its eggs, about a hundred and twenty in number, covering them over with sand; then a second deposit is placed on the top of the first, and so on until the pit is full." This goes on for about fourteen days. "When all have done, the area, or taboliero, over which they have been digging is only distinguished from the rest of the praia by signs of the sand having been a little disturbed.
"On rising I went to join my friends," he continues, "and few recollections of my Amazonian rambles are more vivid and agreeable than that of my walk over the white sea of sand on this cool morning. The sky was cloudless; the just-risen sun was hid behind the dense woods on Shimuni, but the long line of forest to the west on Baria, with its plumy decorations of palms, was lighted up with his yellow horizontal rays. A faint chorus of singing-birds reached the ears from across the water, and flocks of Gulls and Plovers were calling plaintively over the swelling banks of the praia. Tracks of stray Turtles were visible on the 169 smooth white surface, two of which had been caught, for stragglers from the main body are a lawful prize.
"On arriving at the edge of the forest I mounted the sentinels' stage just in time to see the Turtles retreating to the water on the opposite side of the sand-bank. The sight was well worth the trouble of ascending. They were about a mile off, but the surface of the sand was blackened with the multitudes which were waddling towards the river; the margin of the praia was rather steep, and they all seemed to tumble head first down the declivity into the water."
On the 2nd of October the same party left Ega on a second excursion, the object of Cardoza being this time to search certain pools in the forest for young Turtles. The exact situation of these hidden sheets of water are known to few. The morning was cloudy and cool, and a fresh wind blew down the river; they had to struggle, therefore, against wind and current. The boat was tossed about and shipped a good deal of water. Their destination was a point of land twenty miles below Shimuni. The coast-line was nearly straight for many miles, and the bank averaged about thirty feet above the then level of the river; at the top rose an unbroken hedge of forest. No one could have divined that pools of water existed on that elevated land.
A path was cut through the forest by our party with their hunting-knives to the pool, half a mile distant; short poles were cut and laid across the path, over which three light canoes were rolled, after being dragged up the bank. A large net, seventy yards in length, was then disembarked and carried to the place. Netting, however, the older Indians considered unsportsmanlike; and, on reaching the pool, they commenced shooting the Turtles with bows and arrows from light stages erected on the shores.
"The pool covered an area of about four acres, and was closely hemmed in by the forest, which, in picturesque variety and grouping, often exceeded almost anything I had seen. The margins for some distance were swampy, and covered with large tufts of fine grass called matupá. These tufts were in many places overrun with ferns, and exterior to them was a crowded row of arborescent shrubs growing to a height of fifteen or twenty feet, forming a green palisade. Around the whole stood the taller 170 forest trees—palmate-leaved Cecropiæ; slender Assai palms thirty feet high, with their thin feathery heads crowning their gently-curving, smooth stems; and, as a background to these airy forms, lay the voluminous masses of ordinary forest trees, with garlands, festoons, and streamers of leafy parasites hanging from their branches."
The pool which was hemmed in by this gorgeous scenery was nowhere more than five feet deep, and of that one foot was a fine soft mud. Cardoza and the author spent an hour paddling about admiring the skill displayed by the Indians in shooting Turtles. They did not wait for the animals to come to the surface to breathe, but watched for the slightest movements in the water which revealed their presence underneath; that instant an arrow flew from the bow of the nearest man, which never failed to pierce the shell of the submerged animal, and by mid-day about a score of full-grown Turtles had been shot. The net was now spread at one extremity of the oval-shaped pool, its side resting on the bottom, while the floats buoyed the other side up on the surface, the cords being held by two Indians. The rest of the party now spread themselves round the pool, beating the water with long poles, in order to drive the Turtles towards the centre. When they neared the net, the men moved more quickly, beating and shouting with great vigour. The ends of the net were now seized with vigorous hands, and dragged suddenly forward, bringing them at the same time together, so as to enclose all within a circle. Every man then leapt into the enclosure, the boats were brought up, and the captured Turtles were thrown in. In this manner about eighty were secured in twenty minutes.
Among these were several male Turtles, or capetaris, as they are called by the natives. They are much less numerous than the females, much smaller, and more circular in shape; their flesh is considered unwholesome.
On the 17th of October, the day announced for the taboliero, or egg-digging, Mr. Bates made a last excursion in Senhor Cardoza's company. Egg-collecting occupied four days. On the morning of the 17th about four hundred persons were assembled on the sand-bank; each family had erected a rude temporary shed of poles and palm-leaves, to protect themselves from sun and rain. 171 Large copper kettles to prepare the oil, and hundreds of red earthenware jars, were scattered about on the sands. The commandant commenced by taking down the names of all masters of households, with the number of persons each intended to employ in digging; he then exacted from each a fine equal to fourpence a head towards defraying the expense of the sentinels, when the whole were allowed to go to the taboliero. It was exhausted by the end of the second day, when each household had erected large mounds of eggs beside their temporary hut.

The Turtles or Sea Tortoises are distinguished from all others by a comparatively flat carapace, long members, the extremities of which terminate in broad paddles, the anterior much longer than the posterior ones; the toes, though formed of distinct pieces, can only act together, thus constituting true oars, admirably arranged for swimming. Their carapace, besides being flat, is indented and elongated in front, and contracted behind, being disposed in such a manner that the head and feet can be completely hidden.
Marine Tortoises are the largest of their species: they swim and dive with great facility, and can remain long under water. The external orifice of the nasal canal is furnished with a sort of valve, which the animal raises when it is in the air and closes when under water; but it rarely leaves its liquid element except in the breeding season, when nature prompts it to seek the shore to lay its eggs. Some of the species, however, seek the shore in the night, when they frequent the banks of desert and solitary isles, where they browse on marine plants. Although they walk with difficulty, and even with pain, in quiet seas they may be seen floating like a boat, in absolute immobility, and asleep on the surface of the water. With their horny jaws, which are hard and trenchant as the beak of a bird of prey, some of them feed upon sea-weed and algæ, while others feed on living animals, such as crustaceans, zoophytes, and mollusks.
We have seen how regularly and systematically the Land Tortoises 172 proceed in depositing their eggs—nor is less precaution taken by the Sea Tortoise. The females, accompanied by the males, traverse several hundreds of miles of sea in order to deposit their eggs in some favoured locality. Other females resort, year after year, almost to a day, to the sandy shore of some desert isle, where they drag themselves ashore during the night, sufficiently inland to be safe from the tide. In some such spot, using their hind feet by way of a shovel, they excavate holes about thirty inches deep. Here they lay frequently a hundred eggs, covering them up afterwards with the fine sand, levelling the surface, and then returning to sea, leaving the eggs to be hatched by the solar rays. The eggs are round, slightly depressed at both ends, and furnished with a coriaceous shell. From the high temperature communicated to the sand-bank, they are hatched in about fifteen days. The females seem to have two or three layings in the season, at intervals of two or three weeks. When the young Turtles are hatched, they are feeble, white, and about the size of frogs, and their instincts lead them at once to the sea. Under the fostering care of their mother, those which have escaped the birds of prey on their way to the sea, and the fishes lying in wait for them, rapidly develop, and attain, under favourable circumstances, an enormous size,—some of the Sphargis, or Soft Turtles, having been known to weigh from fifteen to sixteen hundred pounds,—while others, whose carapaces measured more than fifteen feet in circumference and seven feet in length, exceeded eighteen hundred pounds.
Marine Tortoises are met with in herds more or less numerous in all seas, principally towards the torrid zone in the tropical regions, on the shores of the Antilles, in Cuba, Jamaica, St. Domingo, the Gulf of Mexico, and in the Indian Ocean. Those occasionally found by navigators in the North Atlantic and Mediterranean seem to be wanderers separated from some travelling bands.
Of all reptiles, the Sea Tortoise is the most useful to man. In countries where they are common, and where they attain an enormous size, their flesh is the most healthy and nourishing food, and their carapace serves as a canoe in which the natives paddle along the shores. They even roof their huts with them; they 173 convert them into drinking-troughs for their cattle and into baths for their children. According to Strabo and Pliny, the ancient inhabitants of the shores of the Indian Ocean and the Red Sea converted the enormous carapaces of the Tortoise which frequented their shores into coverings for their houses, and boats for paddling along the coast. The fat of many species, when fresh, is used as a substitute for oil and butter. When the musk-like odour of this fatty substance, as in Chelonia caouana and C. caretta, becomes too repulsive for food, it is employed in embrocations, in tanning leather, or in lamps. The eggs of nearly all the Turtles are sought after for their flavour. Finally, the carapace of several species constitutes a valuable material much employed in the arts, and known as tortoise-shell. This material is sought after in consequence of its hardness and the fine polish of which it is susceptible, and also for the facility with which it is worked. It has a strong resemblance to horn, but is easily distinguished from it. Though, like horn, it is formed of parallel fibres, it seems to be rather the result of exudation, consisting of a kind of solidified mucus. Its texture is homogeneous; it can be cut and polished with precision and beauty; in short, under the influence of a gentle 174 175 heat, it is softened and can be modelled into any fashion, according to the taste of the moulder; after becoming cool it retains the desired shape.
While most of the Tortoises are highly useful to man, both for food and other purposes, perhaps the most interesting are the Green Turtles (Tortues franches of French authors), Chelonia caouana and Caretta. From these man draws the greatest advantage from their superior size, and from the thickness of their shells. The Green Turtle (Chelonia Mydas, Fig. 40) is so called from the reflected green of its carapace. It abounds in the Southern Atlantic Ocean, where it keeps habitually far from the shore, except in the breeding seasons, when it makes long voyages in order to deposit its eggs, giving a preference for that purpose to Ascension Island and St. Vincent. It rests on the surface of the open sea, and as it sleeps heavily, it is easily taken by a cord with a running knot, which is carefully slipped round its neck as the boat containing the captors silently glides past. It is even said to be a practice with the Malay fishermen to dive beneath them, and attaching a cord to the foot of a sleeping Turtle, thus take it alive.
Many other modes are employed for capturing them. In the regions frequented by them in the breeding season, they are followed by their track on the sands, and their retreat cut off, when met with, by forming a circle round them, when they are thrown on their backs; hand-spikes sometimes being necessary to accomplish this from their great size. In this position they are helpless, and must remain until wanted, so that their enemies have time to pursue their sport elsewhere, as represented in Fig. 41. The next day they are collected or destroyed at leisure. In 1802 the crew of a French ship surprised a female Turtle on the Island of Lobos. The men had infinite trouble in making good its capture and throwing it on its back, for it was strong enough to drag them all towards the sea. It was at last mastered. Its head was as large as that of an infant, and its beak four times the size of a paroquet. It weighed two hundred and sixty pounds, and had in its body three hundred and forty-seven eggs. Turtles are also taken in nets, in the meshes of which their beaks and flippers get entangled; thus prevented from coming to the surface for air, they die of asphyxia. Others harpoon them on the open sea when they come to the surface to breathe. The 176 harpoon is attached to a cord, by which the animal is soon brought to the surface and drawn into the boat. But the commonest mode of capture is approaching them in a boat as they float asleep on the surface—this must be done silently. When within reach, a back flipper is laid hold of by one of the crew, and by a sudden twist the Turtle is thrown on its back, when becoming helpless for the moment, it is dragged on board.
A very curious mode of fishing for Turtle is pursued by means of small fish, a species of Echeneis or Remora. These small fish are provided with an oval plate on the head, which consists of a score of parallel plates, forming two series, furnished on their outer edge with an oval disk, soft and fleshy at its circumference; in the middle of this plate is a complicated apparatus of bony pieces dispersed across the surface, which can be moved on their axis by particular muscles, their free edges being furnished with small hooks, which are all raised at once like the points of a wool-card. The fishermen keep many of these fishes in buckets of water. When they see a sleeping Turtle they approach it, and throw one of these suck-fish into the sea. The fish dives under the Turtle, and fixes itself inextricably to it by means of their cephalic disk. As the fish is attached to a long cord by means of a ring in its tail, the fish 177 is drawn on board along with its victim. This is line fishing of a new kind, in which the hook is living, and pursues its prey in the bosom of the deep.
The Green Turtle, whose flesh is celebrated for its delicacy and excellence of its fat, is that from which Turtle soup is made. Turtle soup is only of recent invention, the first Turtle having been brought to London by Admiral Anson in 1752. It was long a costly dish, and even now, although the introduction of steam and other adjuncts to navigation has greatly modified the expense, its price is about ten shillings per pound weight.
Much of the tortoise-shell of commerce comes from the Green Turtle, but by far the finest specimens are produced by the Imbricated or Hawk's-bill Turtle, Chelonia caretta (Fig. 42). In this species the plates of the disk are imbricated, or lapping over each other, and thirteen in number. The muzzle is long and compressed; the jaws with straight edges, without dentation, curving slightly towards each other at their extremities, with two nails on each fin. It rarely attains the size or weight of the Green Turtle. The Hawk's-bill Turtle is met with in the Indian Ocean, and also on the American shores. It feeds on marine plants, on mollusks, and small fishes, and is chiefly sought after for its shell, which produces the finest tortoise-shell known; while its flesh is rendered 178 unpalatable from its musky flavour. On the other hand, its eggs are excellent when fresh, and eagerly sought after.
In order to prepare the shell, it is softened by means of boiling after being torn from the animal's back. It is then flattened by being passed through a press, previous to being polished. In this condition it is ready for all sorts of ornamental work. The Loggerhead Turtle, or C. caouana (Fig. 43), like the Green Turtle, has its scales placed side by side. Its colour is brownish or deep maroon. It is found incidentally on the French and English coasts, and abounds in the Atlantic and Mediterranean seas. Its length is about four feet; its weight, from three to four hundred pounds. It is very voracious, and feeds principally on mollusks. Its shell is much valued, but its flesh is indifferent, and its fat altogether uneatable; however, it is used in some localities to make lamp-oil.
The Leather-back or Corded Tortoise, Spargis coriacea, differs from every other genus, its body being enveloped in a coriaceous hide; tuberculous in the young, perfectly smooth in adults. The feet are without claws. Seven longitudinal grooves extend from the neck to the tail, which remind one of the seven chords of the ancient lyre. Only one species of Sphargis is known (S. coriacea, 179 Fig. 44). This species is found in the Mediterranean and Atlantic Ocean, and is, with the Hawk's-bill Tortoise, the only species found on the British coast. Its body is a light brown, with the lines of the carapace fawn-colour; its members black, edged with yellow. It attains the length of six to eight feet, and a breadth of about one-fifth of the length: it sometimes attains the weight of fourteen to sixteen hundred pounds. Its flesh is said to be unwholesome, and, on being eaten, to produce severe vomiting and purging. 180
Birds are the spoilt children of nature—the favourites of creation. Their brilliant plumage often assumes the most resplendent colours. They have the happy privilege of moving in space—now fluttering through the air, hunting the insect which flits from flower to flower; now soaring high aloft, and swooping upon the victim it has marked for its prey; now cleaving the atmosphere on rapid wing, and performing journeys of vast extent with great rapidity. Mankind have a profound sympathy with these little winged beings, which charm at once by the elegance of their form, the melody of their song, and the graceful impetuosity of their movements.
Anatomically speaking, birds are connected with the Mammifera by their internal structure. Their skeleton essentially resembles that of the Mammals, the bones being nearly the same, only modified slightly for the purposes of flight.
In birds there is a double circulation. The heart consists of two moieties, or lobes, known as the auricle and ventricle. It is conical in form, and occupies the anterior part of the thorax, its apex passing between the lobes of the liver; but there is little perceptible distinction between auricles and ventricles. Their blood is richer in globules than that of the Mammalia, being more thoroughly permeated by air; the respiratory function is also more energetic, from the same cause—in fact, they consume a larger quantity of oxygen, and produce a proportionately greater degree of heat; for while their lungs are small, and placed in the upper 181 part of the thorax only, where they are confined on each side to a cavity, bounded above by the ribs, and below by an imperfect diaphragm, they are perforated by tubes, which communicate with membranous cells, distributed over the thoracic and abdominal cavities, between the muscles, and beneath the skin,—often in all parts of the body. What distinguishes the bird, in fact, is not the wing; for certain of the Mammalia, as the Bat, and even some fishes, as the Gusard and Exocœtus, can traverse the air by expanding their wings. In birds the diaphragm which arrests the air in the Mammalia is scarcely perceptible, so the external air penetrates into every part of the body by the respiratory tubes, which ramify the whole cellular tissue, the interior of the bones, and even the feathers, and between the muscles. Their bodies, dilated by the air inhaled, lose a proportionate amount of weight; balloon-like, they float in the air, and, from their peculiar forms, they can swim, so to speak, in any direction in the gaseous element.
Wings alone, then, would fail to support the bird in space. 182 The position renders a double system of breathing necessary. Vital heat in animals is always in proportion to their respiration, for the oxygen of the air, which penetrates every cell and cavity of their bones, feathers, and body, warming and giving increased activity to their circulation, and specific lightness to their bodies, from its rich organisation enables birds to live in the coldest atmospheric regions. In Fig. 46 the respiratory organs of a Pigeon are represented. The trachea, or windpipe, is composed of many bony rings, varying in different species. In the Falcons it is slightly flattened, and tapers in a small degree; but in many genera it presents dilatations and contractions, and in others it is variously curved, two slender muscles, which run along its sides towards the sternum, serving to contract it. In many of the song-birds several pairs of small muscles are attached to the lower larynx where the tube bifurcates, by which they are enabled to control this organ, which is the producer of their note.
The trachea carries the air to the lungs in a Pigeon, and separates into two branches in the breast, where it abuts on the aërial sacs, and on the two lungs (Fig. 47). The air carried by 183 the windpipe acts upon the blood through the thin substance of the cells which constitute the pulmonary tissue, in which it traverses in an infinity of minute vessels, whose thin walls are permeable by the gas.
The lungs are small, and placed in the upper part of the thorax, where they are confined on each side by a cavity bounded above by the ribs and below by an imperfect diaphragm; but they are perforated by tubes which communicate with membranous cells distributed over the thoracic and abdominal cavities, between the muscles, beneath the skin, and in all parts of the body—the air even penetrating many of the bones when the species are peculiarly aërial in their habits.
The external form of birds is modified so as to be subservient to aërial progression. The vertebral column, or spine, along the centre of which runs the spinal cord, is divided into three regions—the cervical, dorsal, and sacral regions—terminating in the caudal extremities, the number of vertebræ, or pieces, varying much in different genera. The body consists of the dorsal, sacral, and caudal parts of the column; laterally, of the ribs and pelvis; and beneath, of the sternum and the soft parts contained in it. Its anterior part, containing heart, lungs, and liver, is named the thorax; the posterior, the pelvis. The sternum, with the clavicles and scapulæ, is perhaps the most curiously modified part of the skeleton of birds.
The sternum, then, is a large expanded plate extended over the whole anterior part of the thorax, and even covering more or less what may be considered the abdomen. It varies greatly in different genera; but in all it is more or less four-sided, and convex externally, forming the basis for the powerful muscles by which the wings are moved. These wings serve as arms by which the bird guides itself, ascending or descending according to the impulse given them. "That the anterior form of birds is modified so as to be subservient to the aërial progression for which these animals are intended," says McGillivray, "is obvious and intelligible. Their bodies are oval, with the more powerful muscles placed on the breast, so that, when the horizontal position is assumed, the centre of gravity comes between the wings, and is kept near the lower part by the weight of the pectoral muscles. 184 The length and flexibility of the neck enable the bird to make the necessary changes in the centre of gravity, while the solidity of the dorsal spine gives advantage to the action of the muscles. The head is terminated by a pointed bill, which aids in cleaving the air; the feet, when short, are drawn up and concealed under the feathers; when long, they are stretched out beneath or behind the tail, which is more or less expanded, and helps to support the body in the air, as well as, by acting in the manner of a rudder, to change its direction, or, by being expanded, to break its descent."
The wings of birds are acute or obtuse. The more angular the wing of birds—that is to say, the longer the feathers on the edge of the wing—the more rapidly does it propel itself through the air. The tail consists of a number of feathers, to which are attached a series of small muscles, one for each vertebra, which are capable of depressing and elevating the tail in various degrees; while a series of connections, whose fibres invest the base of the 185 quills, curve round the edge of the tail. Their action is to spread out the tail-feathers, and incline them to the right or left; thus enabling it to perform the part of a helm or rudder as it cleaves the atmosphere.
Besides flight, birds possess other means of locomotion. They are formed for walking or for swimming as well as for flying, according as their habits are aërial, terrestrial, or aquatic. Their general form, though possessing all the characteristics of the class, is modified and adapted to the kind of life they are intended to lead. Where the skin of a bird is covered with feathers, it is observed that the true skin, or derma, is thin and transparent; while the cuticle is thicker, and even covered with scales, in those parts where feathers are absent.
Before addressing ourselves to the physiological functions of birds, a few words descriptive of their feathers, beaks, and claws will not be out of place.
The covering of birds is known by the general name of plumage. It is composed of many individual feathers. The feathers are horny productions, consisting of a hollow tube or barrel, and a stem rising from it. Chemically, this covering is of the same material as the hair on Mammals and the scales on reptiles and fishes, differing only in its mechanical structure. Besides the more conspicuous feathers, most birds have an underneath covering of smaller ones known as down-feathers. A feather of the ordinary kind consists of the tube, or barrel, by which it is attached to the skin, varying in length according to the species; the stem, or shaft, composed internally of a soft, compact, but elastic substance of a whitish colour, and in its buoyancy not unlike cork; the web, which is a lateral prolongation of the external coating of the shaft, and which assumes the form of a thin linear membrane springing from it at an angle more or less acute in different species: this is the barb. From the upper edge of each barb two sets of minute filaments proceed at an angle similar to that of the barb itself in respect to the shaft. These smaller filaments are the barbules, by means of which the barbs are retained in opposition—not by the barbules of one barb interlocking with those of another in the manner of dovetailing, but by the anterior series of one barb overlapping and hooking into the recurvate formation of the barb next 186 to it (Figs. 51, 52). The barbules themselves frequently throw out filaments in the same manner, which are called barbicels, whose object is apparently the same—namely, that of connecting and retaining the barbules in position. These may be observed, by the aid of a small magnifying glass, in the quills of the Golden Eagle, Aquila chrysaëtus.
Feathers, then, consist of three parts—the tube, the shaft, and the webs; the webs being the barbs furnished with barbules, sometimes barbicels. They are convex above, and are thus enabled to resist flexion or fracture better from beneath than from any other direction. They are also elastic; and this property, together with their curvature, tends to keep them closer together. 187
In the feathers of a large portion of birds there is a plumiform formation, or small feather or plumule. This plumule is conspicuous in gallinaceous birds—for instance, the Pheasants (Fig. 53); it springs from the fore part of the tube, just at the commencement of the shafts; it gradually narrows, and is continued in the form of a very delicate, thread-like fibre; from its side proceed two series of barbs, and from the barbs two series of barbules, extremely fine, entirely disunited, and very loose. This plumule seldom exists among aquatic birds, but in gallinaceous fowls it attains the length of two-thirds of the feather, and in the Emu and Cassowary it equals it in length.
Feathers may be divided into those specially employed as the means of locomotion and those intended to protect the bird from extreme cold. The former are much stronger, more compact, and more elongated than the others. The row of feathers bordering the wing behind is known as the alar quills, or wing-quills, and those terminating the extremity of the tail, as caudal quills. From the head, backwards to the tail, the feathers increase in strength and size; those on the face, or round the base of the bill, being smallest, the tail-coverts longest. Immediately covering the base of the wing-quills are a row of feathers on both surfaces of the wing; these are the quill-coverts.
The most brilliant feathers are found in birds of warm climates, and the more tropical the climate the more dazzling and brilliant is the plumage. In many species the brilliant plumage is confined to the males, while that of the females is dark and sombre. In other cases it is the same in both sexes. The young of some species attain the adult appearance after the first moult; others take several years to acquire their full splendour.
Birds cast their feathers at least once a year, in order to put on a fresh dress. This is called moulting—a change which usually occurs in the autumn, but sometimes both in spring and autumn. During the moulting season birds are dull, retiring, and silent; but when they emerge from this state they proudly display their lively colours, which now rival the gayest flowers that surround them.
Among the gallinaceous birds, and especially among the aquatic species, there exist over the coccyx certain receptacles 188 from which is distilled the oily substance with which they lubricate their plumage. These receptacles are known as the uropygial glands. On the lower surface is a layer of cellular tissue containing a similar fluid, which seems to be connected with the growth of the feathers.
The feet of birds are as varied in different species as are their wings. In birds of prey the claws are powerful and hooked. In some the foot is flat and the claw straight and adapted for walking (Figs. 56, 57, 58). The great toe is generally the strongest, but this is not an absolute law: a projection which is found on the leg of some birds, and is designated a spur, is a formidable weapon in some species (Figs. 59, 60). Some birds walk by bringing their feet forward alternately; others by a simultaneous motion, or a succession of leaps. Some run with great velocity, while others walk with great difficulty, and that only on a flat surface. Many have their toes joined by thin membranes, which act as paddles by which they propel themselves through the water.
The beak, or bill, of birds is composed of two bony pieces, called mandibles, surrounded by a horny substance, differing both in 189 form and thickness according to the habits of the species. In the genus Falco the bill is shorter than the head; the upper mandible is furnished at the base with a bare coloured skin, of a peculiar dense texture, called the cere; its outline slightly convex as far as the edge of the cere (Fig. 61), then curved so as to form about the third of a circle, and evidently destined, in connection with its formidable claws, to tear its prey.
In the Toucans Ramphastidæ the bill is half a foot long, hollow within, thin, and nearly transparent; and the mandibles are so disposed as to combine, with their great bulk, strength and lightness, and assisting by their digestive power to assimilate both animal and vegetable food (Fig. 62). In the Pelicanidæ, as in the Common Cormorant, Phalacrocorax carbo, the bill is long, straight, and compound; the upper mandible curved towards the point, the lower compressed; the base inserted in a small membrane which extends under the throat. In the back part of the head is an additional bone (Fig. 63, a), attached in such a manner to the occiput as to admit of great expansion, which permits of its swallowing plaice and other flat fish of considerable 190 size. The Crane, Grus cinerea (Fig. 64), has the bill rather longer than the head, strong, straight, compressed, and pointed at the extremity; the sides of the mandible deeply channelled with nostrils, and closed backwards by a thin membrane.
In the Goose, genus Anser (Fig. 65), we find the bill short, not longer than the head, conical, covered at the base with a cerous skin, with under mandible smaller than the upper. In the Sparrows, Passerina (Fig. 66), the bill is strong and conical, the upper mandible slightly curved, the lower compressed and smaller than the upper; nostrils lateral, basal, round, and partly concealed by the short feathers at the base of the mandibles. In the Goatsuckers, Caprimulgus (Fig. 67), the bill is remarkably small and weak, the sides inflexed and sometimes gaping.
The tongue, like the bill, however, is only an accessory to the digestive apparatus; for while the beak serves the purpose of prehension and trituration, the tongue assists in deglutition or swallowing. Digestion is so active in some birds, that they get fat in an excessively short space of time. The Ortolan Bunting, Emberiza hortulana, and some others, are fattened for the table in 191 five or six days. In the swelling under the throat, called the crop, a (Fig. 68), or first stomach, which is largely developed in some of the granivorous or grain-eating birds, the food remains for a time, where it undergoes certain modifications which facilitate digestion; thence it passes into the succenteric ventricle, or second stomach, b (Fig. 68),—there it imbibes the necessary amount of gastric juice; being finally transformed into chyme in the gizzard, c (Fig. 68), or third stomach, which is possessed of great muscular power, being capable of acting upon the most solid bodies, triturating even the flints and gravel which the gallinaceous birds swallow to aid their digestion.
It is a curious fact that a grain of seed, introduced into the stomach, may be digested without alteration, and ejected where it will germinate, if it meets with no obstacle to its vegetation. In this manner trees are frequently found in regions where their species appear to have been previously unknown.
Chyle, which is a milky fluid formed from the junction of chyme and bile, is received by the small intestine, where the bile also flows from the liver and the saliva from the pancreas.
The urinary apparatus consists of the kidneys, two in number, thick and irregular, and distinct one from the other, abutting on the intestine, which terminates in a species of pouch, or cloaca, through which evacuation, alternately of urine, excrement, and eggs, takes place.
The sense of touch, of smell, of taste, and hearing are only slightly developed in birds. Some have spoken of great delicacy of scent in birds of prey, which are observed to assemble in great numbers on fields of battle and other places where human carcasses are exposed. But the opinions of naturalists, such as Audubon and Levaillant, seem to prove that these animals were attracted rather by the sight than smell.
The organ of sight is, indeed, more highly developed in birds 192 than in any other class of animals. The volume of the eye itself is large compared with the head. It includes an addition which seems to be confined to birds. This is a black membrane, with many folds, very rich in blood-vessels, and situated at the bottom of the ocular globe, and advancing towards the crystalline. Anatomy has failed to explain the use of this, but it is supposed that by advancing or withdrawing it, it gives to birds additional power of vision. Other parts of the eye, such as the choroïds, the thin membrane which covers the posterior part of the eye, the iris, the retina, present nothing remarkable. The white of the eye is surrounded by an osseous or cartilaginous matter, evidently placed there for protection of this delicate and useful organ.
193
Besides the ordinary upper and lower pupils, birds possess a third. This consists of an extensive transparent membrane, disposed vertically, which covers the eye like a piece of network, protecting it from the effects of a blaze of light. It is this pupil, or nictating membrane, placed at the internal angle of the eye, between the orb and the external pupil, which the animal uses at will, which permits the Eagle to gaze at the sun, and prevents the nocturnal birds of prey from being dazzled when exposed to daylight.
The perfection of the sight of birds seems to be proved from the Vulture, so distant from his prey as to appear a mere speck in the heavens, without deviation flying directly to it; or the Swallow, which perceives, while on rapid wing, the smallest insect on which it feeds. According to Spallanzani, the Swift has sight so piercing, that it can see only five lines in diameter at the distance of five hundred feet.
Birds, of all animal creation, can traverse distances with the greatest rapidity. The fleetest among the Mammifera cannot run over five or six leagues in an hour. Certain birds easily traverse their twenty leagues in the same interval of time. In less than three minutes we lose sight of a large bird, such as a Kite or an Eagle, whose body is more than a yard from wing to wing. It is assumed, from these facts, that these birds traverse more than fifteen hundred yards each minute, or more than fifty miles in an hour. A Falcon of Henri II. strayed from Fontainebleau in pursuit of a Bustard; it was taken the next day at Malta. Another Falcon, sent from the Canaries to the Duke de Lermes, in Spain, returned from Andalusia to the Peak of Teneriffe in six hours—the flight representing a distance of two hundred and fifty leagues. In short, the whole organisation gives to a bird that remarkable lightness which contributes so much to its velocity. Not to speak of the feathers with which it is covered, its bones are hollow and form large cells, called aërial sacs, which it is able to fill with air at will, and its sternum is furnished with a bony frame or breast-bone, formed somewhat like the keel of a ship, into which the pectoral muscles are inserted—which, besides being largely developed, in birds of flight possess remarkable contractile properties.
The vocal apparatus in birds, represented in Figs. 70 and 71, 194 is very complicated, and differs from the human larynx and trachea. It consists of a kind of osseous chamber; which, however, is only a swelling in the arterial trachea at the point where it bifurcates and enters the breast to form the bronchial tube. It is this formation, called the lower larynx, which constitutes the organ of song. Five pairs of muscles, attached to the walls of this chamber, stretch or relax the vocal chord, by which means they enlarge or diminish the cavity of the larynx. Whoever has watched any song-bird singing must have noted the swelling and contracting of its throat as it poured out its melody, modifying, in a thousand ways, the tension of the vocal chords and of the larynx, and producing those marvellous modulations whose perfection must always be a subject of astonishment and admiration.
The song of birds must be the expression of some sentiment; they surely sing as much for their own pleasure as to charm those who listen to them. While they fill the woods with their melodious accents they direct their looks on all sides, as if proud of their talents, and desirous of gathering the tribute of admiration to which they feel themselves entitled. Their song varies with the season, but it is in the early spring their efforts are the most successful, and we are most disposed to admire the beauty and harmony of their voices. Can anything be more delicious than the warbling of the Linnet, the piping of the Goldfinch, slowly swelling from their leafy bower, or the melodious cadence of the Nightingale, as it breaks the silence of the woodland during the serene nights of leafy June?
Our landscape would be sad and mute indeed without these 195 graceful inhabitants of the air, which give so much animation to country life and solitary rambles. In the silence of night, when all nature sleeps and life seems suspended, all at once certain notes of harmony rise from under the dense foliage, as if to protest against the universal silence. It is sometimes a plaintive cry, prolonged into a stifled sigh, now a continuous warbling, now a lively song, gay and melodious, which the whole forest re-echoes to.
When the darkness of night gives place to the first dawn of day—when the soft gleam of Aurora has appeared on the horizon, all is transformed, all is vivified on the new-born earth, lately asleep and apparently deserted. The larger birds rise higher and higher in the air, till they are lost in the clouds. The small birds hop from branch to branch with joyous gambols, communicating a movement of happiness and content over all nature. What a wonderful variety of music issues from them—what dazzling brilliancy and variety deck their plumage—what a charm pervades the whole scene, enlivened by these living flowers flitting about in intense enjoyment, hovering, traversing, and embellishing the air! Be it a Titmouse, which seems to spend its life suspended from the branch of a tree; or the Fly Catcher, on the other hand, always perched; the Lark, performing its graceful circles in the air as it rises higher and higher, pouring forth its melodious song more vigorously with each circle described; the Thrush, which runs along the grassy path, watching for its prey, or the House Sparrow chirping from the straw-built roof, or the Robin warbling from some leafless bower—how completely the little winged wanderers decorate the landscape and improve the picture with their innocent gambols!
Assuredly birds have a language which they alone comprehend. When danger threatens them, a particular cry is uttered by one, and immediately all of the same species hide themselves until their fears are dispelled and confidence restored. When the presence of a bird of prey is announced by the plaintive cry of the Thrush, all the feathered race of the neighbourhood are hushed into silence.
Birds of prey with carnivorous instincts live in the most solitary places. The Eagle lives alone with his mate in some unapproachable 196 aerie, his nest placed on the side of some steeply-scarped mountain, or perhaps hidden in the depth of some inaccessible ravine, whence they sally forth to visit some distant region in search of prey.
It is very difficult for us to appreciate the degree of intelligence exhibited by birds. In the Mammifers, whose organisation approaches nearer to that of man, we are enabled partially to comprehend their joys and griefs; but in the case of birds we are reduced to conjecture in order to arrive at an estimate of their sensations. To explain this profound mystery a word has been invented which satisfies easy minds: we call the sentiment which leads birds to perform many admirable actions which are related of them, instinct. The tenderness of the mother for her young—a tenderness so full of delicacy and foresight—is, we say, only the result of instinct. It is agreed on all hands, however, that this instinct singularly resembles the intelligence called reason, and, in the opinion of many, is nothing else.
Reproduction in birds occurs at intervals regulated by nature, and they are distinguished, above all other creatures, for the fidelity of their affections. It is frequently a matter of observation that a male attaches itself to a female, and they henceforth live together till the death of one or both; and many affecting scenes are described where death has overtaken one of the affectionate pair. When the breeding season approaches, the habits of the female are modified; she abandons her former freedom, and, having laid her eggs, she passes her whole time in incubation, defying hunger and all other dangers, apparently well instructed in the fact that the equal and prolonged heat communicated by their contact with her body is necessary to hatch them. During the period of incubation the male, in most instances, watches the female, and supplies her with food; afterwards the little ones are waited on by both the parent birds with the tenderest care until they finally attain the use of their wings.
The solicitude of birds for their young is first manifested in the choice of the locality for the nest, and in the care with which this cradle of their progeny is constructed. But all this disappears when the young no longer require the maternal protection.
In spring, when the birds have paired, they set themselves to 197 work at once to collect the necessary materials for their nest. Each carries its blade of grass or stem of moss. Large birds content themselves with a coarser structure—chips of wood, or branches of trees interlaced with twigs, lined with hair and other soft materials, are fashioned into the necessary shape. But the smaller species really display great art in framing their miniature dwelling, which they furnish inside with wool, blades of grass, or down, the male and female labouring in the common work. Their effort is to make a soft, warm, and solid bed on which to deposit the coming eggs. The mother-bird has recourse to all sorts of cunning devices in order to conceal her nest from prying eyes, choosing for this purpose the heart of a leafy bush, the forked limb, the concealed crack or hollow in the trunk of a tree, the chimneys of a house, crevices in a wall or under a roof. Curiously enough, the nests of the same species are always fashioned in precisely the same manner. 198 The Kinglet, or Wren (Fig. 72), builds its nest under a bank, generally near some brook; it is neatly formed of moss, nearly covered with leaves, and lined with small feathers, hair, and wool. In this nest the smallest of our native birds lays six delicate little white eggs, marked with small pink spots. The Humming-birds (Fig. 73), which flit about in tropical woods, build their nests of grass, lined with feathers. The House Sparrow (Fig. 74) builds its nest under the eave of some house; while the Hedge Sparrow (Fig. 74) chooses the fork of a hawthorn-tree in which to construct its children's home. The Magpie, more ambitious, constructs, in the topmost fork of some tall ash, or poplar, or elm, its nest of branches interlaced with twigs, and lined with fine grass, hair, and other soft materials (Fig. 75). It is a large and consequently a conspicuous fabric, elliptical in form, composed first of rough boughs, on which is laid a quantity of mud, and then a layer of twigs, the whole lined with fibrous roots and other soft material. The Goldfinch builds its nest on trees; it is composed of grass, moss, and lichens, and lined with the down of various plants and such other soft material as comes in its way, elaborately interwoven with wool and hair (Fig. 76).
The Owl, Strix flammea, chooses her nest in some obscure nook of an old tower, the steeple of a church, a dovecot, or the hollow of an aged tree (Fig. 77). It is composed of twigs and straws loosely arranged.
Some birds form into a sort of coarse tissue the fibres of which 199 they construct their nest, which has procured them the name of Weaver Birds. The nest of Fondia erythrops occupies the centre of a bundle of reeds growing in shallow water, in which various grasses are roughly interwoven in the form of a cupola. The Black-headed Synalaxis, S. melanops (Bonaparte), constructs a more delicate fabric, but remarkable for its strength. It builds its nest with grasses, interlacing them in a firm and inextricable web; the form is globular, and the entrance is a small hole in one of its sides. The Orioles and Cassiques of the New World cannot be passed without noticing their wonderful skill in nest construction. The nest of the Baltimore Oriole forms a perfect family pouch, which it suspends from the upper branches of a shrub or tree. The nest of Cassicus hæmorrhous (Cuvier) consists of dry grasses woven into long sacks, gradually increasing in size towards the bottom, with an elongated slit in the side; this is so constructed as to exclude rain from the nest. These wonderful structures are sometimes two yards in length; and when these birds are numerous in the country, the nests, as they hang suspended from the branches of trees, give a singularly novel aspect to the landscape.
Not less curious is the nest of the Tailor Bird, Orthotonia (Fig. 78), which is formed of a large leaf, the two sides of which the bird has contrived to sew together; in the interior is placed the nest. Miraculous indeed is the produce of these little workers. The wonder is how the birds contrive to enter a nest on the wing when the opening seems scarcely so large as the bird's body, and yet it enters without disturbing a fibre. The hut of some savage races is left constantly open, their intelligence not suggesting a protecting door. The Spiders are more ingenious. They contrive to close the entrance to their dwellings, while the door is left habitually open; some birds adopt analogous precautions. In M. Jeudon's book on the Birds of India, he reports a curious arrangement of a species of Homrain: when the female of this bird begins to lay, the male encloses her in their nest by shutting up the door with a thick mud wall, leaving only a small opening by which the female can breathe and receive her food from the male bird's bill; for this severe husband is not forgetful of his duties, but every few minutes conveys some morsel to the enclosed prisoner. 200
Sonnerat, in his "Voyage to India," speaks of a Cape Tit, the nest of which is in the form of a bottle, and composed of cotton. While the female hatches the eggs, the male, like a true sentinel, maintains a strict watch on a specially-formed resting-place, built on one of the sides. Finally, for ingenious construction, instigated by affection for its progeny, there is nothing to compare to the work of the Republican (Fig. 79). This little bird of the Cape, which is about the size of a Sparrow, which it much resembles, lives in numerous families, that unite in forming immense colonies. Their dwellings have the appearance of a circular framework surrounding the trunk of some large tree, as represented beneath. Levaillant counted as many as three hundred cells, which indicate that it is inhabited by six hundred birds. These nests are so heavy that Levaillant was compelled to employ a cart with many men in transporting one of their colonies. At a distance they resemble great roofs attached to the trunks or branches of trees, on which hundreds of birds sport and enjoy themselves. Further, the Oriole suspends its basket-like nest by a twig at the extremity of a flexible branch, placing it thus beyond the reach of any prowling four-footed ravisher. The Magpie selects the topmost fork of the loftiest trees. Again, the nest of the esculent Eastern Swallow, the one so much sought after by gourmands, hangs from those cliffs washed by the sea, 201 and is constructed of a fucus, or marine plant, of the genus Gelidium, which gelatinous substance, cemented by the saliva of the bird, forms a sort of paste of most delicate flavour.
When this nest is built, and the walls properly cemented, and the home of the little brood prepared, the eggs are laid and the process of hatching commences. Eggs are generally numerous in inverse proportion to the size of the bird. The Eagle lays two, for instance, while the Titmouse (Parus) lays from twelve to eighteen.
The eggs laid, the female must now submit to the long and painful labour of incubation. While the male lies in wait in the neighbouring bush to defend his young brood against any enemy which may present itself, giving battle to much larger animals if they venture to attack his nest, the female only quits her charge for necessary food, and her place is often occupied during her absence by her mate. Enemies that lie in wait are numerous. Among them may be enumerated birds of prey, small quadrupeds, reptiles which treacherously insinuate themselves into the nest, and perhaps more unfeeling than all, children with destructive instincts.
If nothing occurs to disturb the repose of the pair, the male, perched upon a neighbouring branch, pours out a song expressive of his felicity. The little ones are finally hatched. Helpless and incapable, without feathers and with closed eyes, they are utterly dependent on the parent birds, by which they are fed until the time when they are covered with feathers. They now begin to try their wings, and find their own food. The mother directs their first efforts, uttering a peculiar cry to attract them when she discovers a favourite morsel; defending them courageously, and, with a total abnegation of self, meeting the most formidable enemies; sometimes going so far for their protection as to offer herself a victim. How pitiful are the cries of a Swallow whose nest is built under the roof of a house on fire! Fearlessly she rushes on the flames, flying to the assistance of her young, as if she would rescue them or perish under the fatal roof. Or mark the unhappy Partridge which the sportsman has surprised on the nest. She hesitates not to offer herself a sacrifice, throwing herself almost under the intruder's feet, in order to attract his attention from her progeny. 202
When the young are strong enough to take wing, they abandon the family tie, and soon lose themselves in the great world of nature, forgetful of their parents' unselfish care. The ingratitude of their first-born does not, however, discourage the forsaken couple. With the returning season they renew their labours, exhibit the same solicitude, the same affection, to meet with the same return. Nature is an unfailing source—an eternal focus of tenderness and love.
Most families of birds are migratory; that is, they abandon their summer quarters and undertake long journeys at certain seasons. These migrations occur with the greatest regularity. By their departure from temperate or cold climates they prognosticate the approach of winter, as their return heralds spring. Among the ancient Greeks, as we learn from a passage of Aristophanes on birds, the arrival of the Crane pointed out the time of sowing; the arrival of the Kite the sheep-shearing season; and the arrival of the Swallow in Greece was the date for putting off summer clothing. The impulse which causes birds to depart is an instinctive desire to find climatic conditions appropriate to their wants of life. At the approach of winter they desert the regions of the north in search of southern countries with a warmer climate, while others migrate northwards to escape the heat.
Nevertheless, all birds are not migratory; many species remain during their whole lives in the locality where they were hatched, straying but little distance from their birth-place. The majority of those which migrate perform their journeys annually and with great regularity; a few irregularly and accidentally; that is, they are caused by necessity, or by atmospheric influences, to change their residence; and it is no unusual sight on such occasions to see numerous flocks of birds assembling under the leadership of a chief, and taking their flight in perfect order, traversing seas, and passing from one continent to another, with astonishing rapidity. On the 22nd of September, 1771, White, of Selborne, witnessed the flight of a flock of Swallows which had rendezvoused the night before in a neighbour's walnut-tree. "At dawn of what was a very foggy day, they arose all together in infinite numbers, occasioning such a rustling from the strokes of their wings against the hazy atmosphere that the sound might be heard at 203 a considerable distance." In the Old World, choosing a time when the winds are favourable, most migratory birds direct their flight towards the south-west in the autumn, and the north-east in spring. In America the migratory birds take a south-east direction in autumn, and the reverse in spring. These aërial travellers instinctively direct their flight to the same regions—often to the same district; and there are good grounds to believe that the same pair frequently find their way year after year to the same nest.
The duration of the life of birds in a state of nature is one of those subjects on which little is known. Some ancient authors—Hesiod and Pliny, for example—give to the Crow nine times the length of life allotted to man, and to the Raven three times that period; in other words, the Carrion Crow, according to these authors, attains to seven hundred and twenty years, and the Raven two hundred and forty. The Swan, on the same authority, lives two hundred years. This longevity is more than doubtful. Paroquets, however, are known to have reached more than a hundred. Goldfinches, Chaffinches, and Nightingales unquestionably, even in the confinement of a cage, have lived four-and-twenty years. A Heron, Girardin tells us, lived fifty-two years, which was testified by the ring which he bore on one of his legs, and even then he lost his life by an accident, while in full vigour. A couple of Storks, moreover, have been known to nestle in the same place for more than forty years. All that we can affirm is that birds live much longer than the Mammalia.
We can easily fix a circumscribed geographical boundary to any species of Mammalia. They may be limited to a country, or even a district. Can we impose a like distribution on birds? At first sight this seems difficult: their powerful organs of locomotion permit of their travelling rapidly; and, moreover, their nature, essentially mobile, and their wandering humour, lead them to continual change; and then their organisation adapts them for great extremes of temperature—circumstances which would lead us to consider them quite cosmopolite. Nevertheless, many species reside habitually in countries of very limited range. A Sovereign Hand has traced on the surface of the globe limits that cannot be passed. How such small creatures are able to perform such distant journeys, pausing only at far-severed resting-places for necessaries, 204 has always been a matter of surprise. They pass on without an instant's sleep, however long and fatiguing the route. How can the Quail, for instance, with its short wing and plump body, traverse the Mediterranean twice in the year? Hasselquist tells us that small short-winged birds frequently came on board his ship in squally weather, all the way from the Channel to the Levant; and Prince Charles Bonaparte was agreeably surprised by the visit of a party of Swallows to the ship Delaware, in which he was a passenger, when five hundred miles from the coast of Portugal, and four hundred from Africa. Audubon relates a similar occurrence; and numerous instances are recorded in which these fatigued travellers have taken shelter in the first fisherman's boat they met, sometimes so weak as to be hardly able to move a wing. It is therefore a fact truly inexplicable, in spite of every hypothesis, more or less reasonable, which has been advanced by naturalists in explanation.
Men have little influence over birds, and have, therefore, few opportunities of studying their habits in a state of nature. Some few species may be retained in captivity, and some observers have been able to obtain their entire confidence while in that condition; but, except two or three species, it has not been possible to reduce them to a state of domestication. Our knowledge of the habits and manners of the feathered race is, therefore, entirely dependent on chance observation.
The Humming-bird is confined to certain portions of America. The Nightingale, if a visitor to Scotland, is only found in Berwick and Dumfriesshire in fine seasons, while it is constantly seen in Sweden, a country much colder and much more northerly. The Toucans, so brilliant in plumage, are only found in tropical South America. The Swallow, so rapid on the wing, clearing its twenty leagues an hour when it leaves us for its southern winter quarters, never deviates from the route which seems to have been traced for it by a Sovereign Master.
It may, then, be stated that the great zones of the earth differ as much in birds as in the Mammifers found in them. We find in climatic regions birds, or groups of birds, of perfectly distinct species, and which are rarely found beyond that particular zone. Glancing at the various countries forming a 205 region, particular types of birds are easily recognised. Africa, for instance, alone possesses the Great Ostrich, while only a small species exists in America—the Rhea; the Emu represents the genus in Australia. Africa has species brilliant as the most precious stones. To America belong exclusively the Humming-birds, so remarkable for the brilliancy of their plumage. Again, if Africa is the country of the Vulture, to America belongs the Condor.
Nevertheless, the acclimatisation of birds is by no means beyond our power. Experience proves that by carrying a bird far from its native country, and placing it in conditions approaching those to which it has been accustomed, it will live and multiply—acclimate itself, in short, to its new home.
Europe possesses no ornithological type peculiar to it. It is only in Africa and America that we find those rich varieties of form and colour which characterise the feathered race. The Island of Madagascar is the land which possesses the greatest number of ornithological types—simply, perhaps, because that island abounds in species whose rudimentary wings do not permit of their wandering away. Whatever the cause, however, the species found there are not obtained elsewhere. Here we find the unique Dodo, a form of animal which became extinct in Europe in the last century.
There is a wonderful charm of companionship in birds—they give animation to the scene, skipping from bush to bush, or skimming the surface of land and water. They please the eye by their graceful shape and plumage, and they charm our ears by their ceaseless warblings. Even in this sense we lie under a debt of gratitude to these graceful inhabitants of the air. But this is far from being the limit of the benefits we derive from them. The birds of the poultry-yards furnish our most delicate food; their eggs form a considerable branch of trade, and are indispensable in the kitchen; and what would become of our country gentleman should our game birds ever become extinct?—an event by no means improbable, seeing that, in the year of grace 1868, the head-dress of every votary of fashion was decorated with the wing of a bird—not confining the demand to Birds of Paradise, Ostrich, Pheasant, and other feathers of brilliant plumage whose 206 value was a protection, but extending to the harmless sea-fowl, which were destroyed by thousands only for the sake of their feathers.
Birds are useful to man by their feeding on the insects, larvæ, and caterpillars which infest cultivated crops. Without their aid, agriculture would become impossible. In former times it was a favourite doctrine with the agriculturist that the Passerina were the real destroyers of his crops, and a war of extermination was declared against them; but the observations of more enlightened persons have demonstrated that the chief food of most of these consists of insects, and the havoc among them has consequently been stayed; still much ignorance, and its concomitant, cruelty, exist on this point. Elsewhere, those interested soon discovered that the destruction of small birds led to formidable increase in the numbers of voracious insects—that these lively and joyous creatures, which float in the air and twitter on the bough, are sent us more for good than evil, and that if some of them make the crops pay a tax, they repay it tenfold by keeping down the excess of more destructive ravagers.
While the smaller birds have proved essentially beneficial to man, some of the larger birds exhibit similar tendencies. The Wading Bird clears the earth of serpents and other unclean and venomous animals. The Vultures and Storks throw themselves in flocks on corrupt carrion, and divest the soil of all putrefying objects: thus, in concert with insects, birds are the scavengers of the earth, lending their aid to make it a fit residence for man; in fact, are constituted by nature guardians of the public health.
In former days Falconry afforded a stately and picturesque sport to the great, in which lords and noble dames assisted. This pastime still exists in some parts of England and some portions of the East, especially in Persia, where the Falcon is trained to chase the Gazelle and small ruminants; while in China and Japan the Cormorant and Pelican are taught to fish the rivers for their masters. From very ancient times, the Carrier Pigeon was the bearer of messages now transmitted along the electric wires with lightning speed.
Nor do these benefits comprise all the claims of birds to the 207 gratitude of man. In tropical America the Agami, Trophia crepitans, or Trumpet Bird of Guiana, is domesticated, and so docile in its habits, that it is employed to watch the flocks, which it does with the fidelity and intelligence of a Dog. "The Agami," says M. Monocour, "is not only tamed easily, but becomes attached to its benefactor with all the fondness and fidelity of a Dog. When bred in the house, it loads the master with caresses, and follows all his motions, but is easily offended." It is bold and obstinate, and will attack Cats and Dogs, fighting a tough battle with one of the latter, however considerable his size. In Cayenne the denizens of the poultry-yard are confided to its care; it leads them to their pasture, prevents them from straying to a dangerous distance, and brings them home in the evening, just as a trained shepherd's Dog will do the flocks committed to his care, and it manifests its delight by cries of joy when its master vouchsafes a caress in return for its faithful service. The Kamichi, which belongs, like the Agami, to the same order, possesses similar characteristic intelligence. Like the former, it is sociable and susceptible of education, and becomes a useful auxiliary to the inhabitants of South America.

The Natatores are obviously devoted, by their organisation, to an aquatic life. Their constant haunts are found on the great rivers and lakes, or on the coast. They are chiefly characterised by the form of their feet. The toes are united by marginal membranes in the Coots and Water-rails, or in others by the extension of webs between and uniting the toes, of a soft membrane slightly lobed; hence the name of Palmipedes, or web-footed, usually applied to them. These broad palmate feet, acting at the end of a long lever, strike the water with great force when fully expanded, being favoured by their backward position. When the bird recovers its stroke, the toes are relaxed in their forward movement, preparatory to another effort; thus progression through the water is obtained.
Some of the swimming birds in their flight are feeble and slow; others are incapable of even rising from the water, being only furnished with rudimentary wings. Again, there are species which possess extraordinary powers of traversing the air, their well-developed wings enabling them to pass through space with wonderful rapidity. The Albatross is met with on the high seas at a vast distance from the shore. Others, as the Petrels, seem to revel in storms and tempests, mingling their wild cry with that of the storm-tossed waves. The sailors, who look anxiously to windward at the dark horizon, where the clouds are surcharged with torrents of rain ready to burst on the ship, are assured of the approaching tempest by the circling flight of the white-winged Albatross, as it is seen through the obscure and threatening mist. 211
The whole order of Natatores swim and dive without saturation, their plumage being anointed by an oily liquid furnished by certain glands in their skin, which renders them impervious to moisture. This immunity from the effect of water is further assisted by the disposition and structure of their feathers, which, being smooth and three-cornered, with the barbules closely interlaced, cause the water to glide off their polished surface; while the down beneath the feathers of which we have spoken protects their bodies from the cold, maintaining their natural heat, and enabling them to resist the cold of the most rigorous winter.
The Natatores are numerous both in species and individuals, having their habitat in all countries. According to Prince Charles Bonaparte, one of the most eminent of European naturalists, those which frequent the sea-shore alone constitute one-fourteenth part of all the birds on the globe, and the number of species he reckons at nine thousand four hundred. They feed on vegetables, insects, mollusks, and fishes. They seek the coast in the breeding season, where they build their nests on the sand, or in nooks and crannies of the rocks, or on the margin of lakes and rivers.
In the spring the sea-birds assemble in large flocks, pair off, and proceed to deposit their eggs in nests constructed generally without skill, but always lined or carpeted with a fine down, which forms a soft warm bed for the embryo progeny. Certain localities are frequented by preference, which are occupied by innumerable flocks in the breeding season, all of which seem to live together in perfect harmony. Some of the families of the Natatores are valuable additions to the poultry-yard. Ducks and Geese furnish delicate and nourishing food for man; the Swan is gracefully ornamental on our lakes and ponds. The down of all the aquatic birds is of immense value to the commerce of northern countries. The eggs are good to eat, and in many countries the inhabitants consume them in great quantities. Nor does their usefulness end here. Guano, so eagerly sought for by the farmer, is the excrement of aquatic fowls—the accumulation of ages, until, in the South Pacific Ocean, it has formed whole islands, some of them being covered with this valuable agricultural assistant to the depth of ninety or a hundred yards. Nor is this so marvellous, if it is considered that twenty-five or thirty thousand 212 sea-birds sleep in these islets night after night, and that each of them will yield half a pound of guano daily. Our lands receive valuable assistance to fertility from this unrivalled material, which owes its power to the ammoniacal salts, phosphate of lime, and fragments of feathers of which it is composed.
The order of Natatores, or Palmipedes, consists of four families:—1. Brevipennes, or Divers; 2. Longipennes, or Skimmers; 3. Totipalmates, or Pelicanidæ; 4. Lamellirostres, including Geese, Ducks, Swans, and Flamingos.
Penguins, Aptenodytes; Auks, Alca; Grebes and Divers, Colymbus; Guillemots, Uria.
The birds which constitute this family of the Natatores are characterised by wings so thin and short as to be totally useless for the purposes of ærial locomotion. They are also called Brachypteres, from the Greek compound βραχυς, short, and πτερα, winged. These are all habitual divers and indefatigable swimmers, using their wings as fish do their fins. To raise these after making the down-stroke requires a considerably greater effort than a bird of flight makes in raising its wings in the air, for which reason the second pectoral muscle in this and other diving birds has an unusually large development to give further strength. Their plumage is smooth and silky, and impervious to water from its oily nature. They live chiefly on the sea, coming ashore in the breeding season.
The Divers, Colymbus, are distinguished from other Brachypteres by their beak being longer than the head, straight, robust, and nearly cylindrical, slightly compressed on the sides, acute, the upper mandible longer than the lower; their toes, in place of being each furnished with marginal membranes, have the three united by a single membrane; their feet being placed far backward and on the same perpendicular line with the tibia—an arrangement very unfavourable for walking, compelling the birds to take a vertical position, rendering their movements on land both painful and difficult.
They are, however, intrepid swimmers, and they dive with such 213 alertness that it requires a quick eye and hand to shoot them. They are inhabitants of northern seas; there they build their nests in some solitary islet or desert promontory, where they lay two eggs, oblong in shape, and more or less shaded of an Isabella white. Fish, particularly the herring, form their principal food; crustaceans and marine vegetables are also eaten by them. Their flesh is tough and leathery, and tastes disagreeable. In the winter they migrate to temperate countries, where they frequent the rivers and lakes, returning to the northern regions when the ice has broken up.
There are three species described: the Great Northern Diver, Colymbus glacialis; the Arctic Diver; and the Imber Diver. But there is considerable doubt on this subject, the young of C. glacialis of the first and second year being so unlike the parent birds as to have been long supposed a distinct species.
English Synonyms.—Northern Diver: Montagu, Selby. Speckled Diver, Ember Goose: Gunner. Ring-necked Loon.
Latin Synonyms.—Colymbus glacialis: Linn., Adult, Latham, Jenyns, Brien. Colymbus Immer: Young, Linn., Latham.
French Synonym.—Plongeon Imbrim: Temminck.
The Great Northern Diver is among the mass of those birds which seek their food on the bosom of the great deep. It is not numerous in British waters, and can scarcely be called gregarious, although adults sometimes, and the young more frequently, form small parties of two to five. A wanderer on the ocean, it not only frequents the margins of the sea, fishing in the bays and estuaries, but it is also met with many miles from the shore. Narrow channels, firths, coves, sea-locks, and sandy bays are, however, its favourite resorts; there it floats, the body deeply immersed in the water. But though deep in the water, it moves on steadily and majestically; it overtakes and shoots ahead of all its more buoyant congeners. But let us watch the actions of a pair of these children of the ocean, and listen while Mr. McGillivray describes one of those picturesque scenes in which he delights. "It is now the 214 end of spring, when the returning warmth gives an increase of animation to the wandering tribes of the winged inhabitants of the ocean air; but the Loon makes comparatively little use of his wings, and his great bulk and robust frame would be ill adapted for the hovering flight of the Gulls and Petrels. There he comes, followed by his mate, advancing with marvellous speed. They have rounded the point, and now stop for a moment to cast a searching glance along the shore, lest an enemy should be lurking there. Forward they start—the smooth water rippling gently against their sides. Small effort they seem to make, and yet powerful must be the stroke of the oars which impel masses so large at so rapid a rate. Now and again they dip their bills into the water; then the head and neck. One glides gently under the surface, without plunge or flutter, and in a few seconds it appears with a fish in his bill, which, with upstretched head and neck, it swallows. The other having also dived, appears with a fish, larger, and less easily managed. She beats it about in her bill, plashing the water, and seems unable to adapt it to the capacity of her gullet; but at length, after much striving, she masters it, and continues her search. Backwards and forwards, over the clear sand of the shallow bay, they glide in their quiet way, and now they have both dived with their heads towards us. One rises close to the sea-weed, and so near to us, that we might almost count the spots on his back. The other, in emerging, has perceived us, and somehow communicates the discovery to her mate. They swim about for a short while with erected necks, then sink into the 215 water, their heads disappearing last; and when we see them again, they are three hundred yards distant, standing out to sea, with half-submerged bodies." "If shot at and not wounded," continues this most picturesque of writers on Natural History, "it never flies off, but dips into the water and rises at a great distance, and unless shot dead, there is little chance of procuring it, for its tenacity of life is great, and its speed far exceeds that of a four-oared boat."
The great American naturalist, Audubon, has left a most interesting account of this bird in his "Ornithological Biography." After describing the various Transatlantic localities in which he has studied its economy, he describes its nest. "One that I saw," he says, "after the young had left it, on Lake Cayuga, was almost afloat, and rudely attached to the rushes, more than forty yards from the land, though its base was laid on the bottom, the water being only eight or nine inches deep. Others I examined in Labrador were placed on dry land, several yards from the water, and raised to the height of nearly a foot above the decayed moss on which they rested. The nest, however placed, is bulky, and formed of withered grasses and herbaceous plants found in the neighbourhood. The true nest, which is from a foot to fifteen inches in diameter, is raised to the height of seven or eight inches. Of the many nests I have examined, more contained three than two eggs, and I am confident that the former number most frequently occurs."
Of this handsome bird Sir John Richardson remarks, contrary to the generally-received notion, that it is seldom seen either in the Arctic Sea or Hudson's Bay, but that it abounds in all the inland lakes. It is rarely found on land, being ill fitted for walking, but admirably adapted to aquatic habits, swimming with great swiftness and for considerable distances under water; and when it does come up, seldom exposing more than its neck. It flies heavily, but rather swiftly, and in a circle round those who have disturbed it in its haunts; its loud and melancholy cry resembling the howling of the Wolf, or the distant scream of a man in distress. When the Loon calls frequently, it is supposed to portend a storm. In the bad weather preceding the advent of winter on the smaller northern American lakes, previous 216 to migration, their wild, weird note is so unnatural, that both the Indians and settlers ascribe to it supernatural powers.
The Imbrine Diver, L'Imbrim of Buffon, is also a fine bird of blackish plumage shaded with white, the belly and a ring round the neck being also white. The head is of a changeable black and green colour. When it has young, in place of diving under water, as its ordinary habit is when threatened, it boldly attacks its enemies with its beak. Its skin serves the Greenlanders as clothing. It inhabits the Arctic seas of both hemispheres, is abundant about the Hebrides, in Norway, in Sweden, and even on the coast of Scotland. Its appearance on the French coast is very irregular, and only after great storms.
The Arctic Diver, C. arcticus, has the beak and throat black; summit of the head ashy grey; the breast and the sides of the neck white, with black spots; the back and rump black; the coverts of the wings with white spots, and all the lower parts pure white. The bird, though rare in England and France, is very common in the North of Europe. It is found on the lakes of Siberia, of Iceland, in Greenland and Hudson's Bay, and sometimes in the Orkney Islands. The women of Lapland make bonnets with its skin dressed without removing the feathers; but in Norway it is considered an act of impiety to destroy it, as the different cries which it utters are said to prognosticate fine weather or rain.
English Synonyms.—Black-throated Loon, Black-throated Diver: Montagu, Selby.
Latin Synonyms.—Colymbus arcticus: Linn., Latham, Temminck, Jenyns, Yarrell, Bonaparte.
French Synonyms.—Plongeon Lumme: Temminck. Plongeon Arctique: Cuvier.
Smaller and more slender than the Great Northern Diver, this species retains many of its characteristic habits. It floats deep in the water, and when alarmed swims at surprising speed, with outstretched neck and rapid beat of the wings, and little more than its head above the surface. It flies high and in a direct course with great rapidity. Mr. Selby describes an ineffectual pursuit of a pair 217 on Loch Shin, in Sutherlandshire, which was long persevered in. In this case submersion frequently took place, which continued for nearly two minutes at a time, and they generally reappeared at nearly a quarter of a mile distant from the spot at which they went down. In no instance did he ever see them attempt to escape by taking wing. "I may observe," says this acute ornithologist, "that a visible track from the water to the nest was made by the female, whose progress on land is effected by shuffling along upon her belly, propelled from behind by her legs." When swimming, they are in the constant habit of dipping their bill in the water with a graceful motion of the head and neck.
The eggs, of which there are two, sometimes three in the same nest, are of a very elongated oval form, three inches in length, two inches in their greatest girth, and of a brownish olive sprinkled with black or dark-brown spots, and are larger at one end than at the other.
English Synonyms.—Red-throated Loon, Red-throated Diver: Montagu, Selby, Yarrell. Speckled Diver: Montagu.
Latin Synonyms.—C. septentrionalis: Linn., Latham, Jenyns, Bonaparte, Temminck. C. borealis, Siviatus, and stellatus: Latham.
French Synonyms.—Plongeon Col Marin, ou à Gorge Rouge: Temminck.
The Red-throated Diver is smaller than either of the preceding, the plumage is dense and firm, the wings of moderate length, the tail rounded and firm.
From the beginning of October to the middle of May these birds are constantly found on our northern coasts, and on the rivers and estuaries with which they abound. When on a long journey, they keep at a great height, moving rapidly in a direct course with outstretched wings. On these occasions they exceed the speed of most of their congeners. With their long outstretched necks and snow-white breasts, from their comparatively short wings, they present a curious and novel sight. When swimming they are extremely vigilant, and permit nothing to approach them. On the appearance of a boat they glide as it were out of sight under the water, without noise or flutter, and thence pursue their way with great rapidity, using wings as well as feet to propel themselves. 218
Belong exclusively to cold countries. They rarely quit the vicinity of land, yet only take to the shore in the breeding season, or when driven by squalls and storms from their favourite element. On shore they are compelled to sit erect. They carry the head very high and the neck stretched out, while their short winglets are advanced like two diminutive arms. When they sit perched in flocks on some lofty projecting rock they might be mistaken at a distance for a line of soldiers.
At certain periods of the year the Penguins assemble on the beach as if they preconcertedly met for deliberation. These assemblies last for a day or two, and are conducted with an obvious degree of solemnity. When the meeting results in a decision, they proceed to work with great activity. Upon a ledge of rock, sufficiently level and of the necessary size, they trace a square with one of its sides parallel and overlooking the edge of the water, which is left open for the egress of the colony. Then with their beaks they proceed to collect all the stones in the neighbourhood, which they heap up outside the lines marked out, to serve them as a wall, to shelter them from the prevailing winds. During the night these openings are 219 guarded by sentinels. They afterwards divide the enclosure into smaller squares, each large enough to receive a certain number of nests, with a passage between each square. No architect could arrange the plan in a more regular manner.
What is most singular is that the Albatross, a bird essentially aërial, and adapted for flight, associates at this period with these half fish, half birds, the Penguins; so that the nest of an Albatross may be seen next the nest of a Penguin, and the whole colony, so differently constituted, appear to live on the best terms of intimacy. Each keeps to its own nest, and if by chance there is a complaint, it is that some Penguin (probably the king Penguin, for he is generally the greatest thief) has robbed the nest of his neighbour, the Albatross.
Other sea-birds come to partake of the hospitality of the little republic. With the permission of the masters of the coterie they build their nests in the vacancies that occur in the squares.
The female Penguin lays but one egg, which she only abandons until hatched for a few instants, the male taking her place while she seeks her food. The Penguins are so numerous in the Antarctic seas that a hundred thousand eggs have been collected by the crew of one vessel.
The Manchots (Fig. 82) have been described by most of the French naturalists as a distinct species, but there is little doubt of their being only a variety of the Aptenodytes. They abound in the southern seas. Their short, stunted wings, which quite incapacitate them from flying, are reduced to a flat and very short stump, totally destitute of feathers, being covered with a soft down, having something of the appearance of hair, which might be taken for scales. Like the Penguin, the Manchots are excellent swimmers and incomparable divers, and their coating of down is so dense that it even resists a bullet; it is consequently difficult to shoot them.
Everything about these birds indicates their adaptation to an aquatic life. Their feet are placed at the extremity of the body—an arrangement that renders them awkward and heavy when ashore; where, in short, they only come to lay and hatch their eggs. They begin to assemble in great numbers at the commencement of October. Their nests are a very simple construction; for they 220 content themselves with digging in the sand a hole deep enough to contain two eggs—but more often one than two.
In spite of the limited number of eggs, the quantity of these birds found in the south of Patagonia is something prodigious. When sailors land in these high latitudes they take or kill as many as they choose. Sir John Narborough says, speaking of those at the Falkland Islands, that "when the sailors walked among the feathered population to provide themselves with eggs, they were regarded with sidelong glances." In many places the shores were covered with these birds, and three hundred have been taken within an hour; for generally they make no effort to escape, but stand quietly by while their companions are being knocked down with sticks.
In another islet, in the Straits of Magellan, Captain Drake's crew killed more than three thousand in one day. These facts are not exaggerated. This island, when visited by these navigators, was, so to speak, virgin; and the birds had succeeded each other from generation to generation in incalculable numbers, hitherto free from molestation.
The Penguins have no fear of man. Mr. Darwin pleasantly relates his encounter with one of these birds on the Falkland Islands. "One day," he says, "having placed myself between a Penguin (A. demersa) and the water, I was much amused by the 221 action of the bird. It was a brave bird, and, till reaching the sea, it regularly fought and drove me backwards. Nothing less than heavy blows would have stopped him. Every inch gained he kept firmly, standing close before me firm, erect, and determined, all the time rolling his head from side to side in a very odd manner, as if the powers of vision only lay in the anterior and basal part of each eye." This bird, Mr. Darwin states, is called the Jackass Penguin, from this habit, when on shore, of throwing its head backwards, and of making a loud strange noise very like the braying of an ass.
They defend themselves vigorously with their beaks when an attempt is made to lay hands upon them; and when pursued, they will pretend to retreat, and return immediately, throwing themselves upon their assailant. "At other times they will look at you askance," says Pernetty, "the head inclined first on one side, then on the other, as if they were mocking you." They hold themselves upright on their feet, the body erect, in a perpendicular line with the head. In this attitude they might be taken for a party of choristers with white surplices and black gowns. Their cry strikingly resembles the braying of an ass. Navigators passing these islands of the southern seas might suppose that they were densely inhabited, for the loud roaring voices of these birds produce a noise equal to that of a crowd on a fête day. The flesh is most unpalatable, but it is frequently the only resource of ships' crews who find themselves short of provisions in these inhospitable regions. As to the eggs of most of the Palmipedes, they are said to be excellent.
The Grebes (Podiceps) have the head small, the neck somewhat elongated, the legs attached to the abdomen, the tail rudimentary, the tarsi compressed, the anterior toes united at their base by a membrane slightly lobed in its contracted extent. These birds live principally on the sea, but they inhabit fresh water by preference, feeding on small fishes, worms, mollusks, insects, and the products of aquatic vegetation. While they dive and swim admirably, they also fly with vigorous wing when pursued; but 222 they rarely ascend into the air unless they are alarmed, or under migrating impulse, which disperses them among the interior lakes in the autumn, and compels them to select a favourable breeding-place in the spring.
The nest of the Grebe is usually placed in a tuft of rushes, on the edge of the water. It is composed exteriorly of large grassy plants roughly interlaced, and the interior is lined with soft broken grasses delicately arranged. The eggs vary from three to seven. On shore they cannot walk at all, but creep, so to speak; for they must hold themselves nearly upright, supported on the croup, the toes and the tarsi being extended laterally. But ungraceful as they are on shore, so much greater is their elegance on the water. They are covered with a close warm down—so close and so lustrous, that muffs of a silvery white are made of the down-covered skins of their breast, which are impervious to water.
M. Noury, Director of the Museum of Natural History at Elbœuf, who has carefully studied the habits of the Grebes, relates of the Castanean Grebe, P. cornutus, that its nest is a perfect raft, which floats upon the surface of our ponds and lakes. It is a mass of thick stems of aquatic herbs closely woven together; and as these materials contain a considerable quantity of air in their numerous cells, and from disengaging various gases besides in decomposing, these aëriform supporters render the nest lighter than the water. In this improvised ship, and upon this humid bed, the female Grebe silently sits upon and hatches her progeny. But if anything unforeseen disturbs her security, this wild bird plunges one foot into the water, which she employs as an oar to transport her dwelling from the threatened danger.
Grebes are inhabitants of the Old and New Continents. Among the European species may be noticed the Crested Grebe (Podiceps cristatus), Fig. 83, about the size of a Duck, ornamented with a double black crest; the Horned Grebe (P. cornutus), provided with two long tufts of feathers, in form somewhat resembling a horn; the Eared Grebe (P. auritus), distinguished by its beak, the base of which is depressed, while the point is raised upwards. Among the American species may be mentioned P. Carolinensis and P. rubricollis, killed at the Great Slave Lake, along with P. cristatus and P. cornutus. P. Chilensis and P. Americanus 223 are natives of the warmer parts of America, of St. Thomas, St. Domingo, and the Philippines.

The Crested Grebe is found along our coasts, and in their estuaries, in limited numbers; but in the splendid lakes of the North American fur-countries, according to Dr. Richardson, this species is very abundant. Mr. Audubon says that it returns to the United States from its northern wanderings about the beginning of September, and proceeds south as far as Mexico, a few stragglers only remaining on the lower part of the Ohio, Mississippi, and the neighbouring lakes. "They pass swiftly through the air," says this enthusiastic naturalist, "at the height of about a hundred yards, in flocks of from seven and eight to fifty or more, proceeding in a loose body, and propelling themselves by continual flappings, their necks and feet stretched out to their full extent. When about to alight on the water, they glide swiftly downward, with their wings half closed, producing a sound not unlike that of a Hawk swooping upon its prey. At this moment their velocity 224 is so great that, on alighting, they glide forward on the surface of the water for twenty or thirty yards, leaving a deep furrow in their wake. They are exceedingly quick-sighted, and frequently elude, by diving, the shot which is aimed at them."
The Guillemots (Uria), Fig. 84, have the beak long, straight, convex above, somewhat angular below, a little curved and hollowed at the extremity of each mandible; the legs are short, compressed, and placed well behind the body; the three anterior toes are united by the same membrane; the claws recurved and pointed; no hind toe; the wings are straight, and the tail short. These birds, when placed on the ground, raise themselves with great difficulty, owing to the conformation of their legs. They only come ashore when driven there for shelter by the storm, or for breeding. For the latter purpose they choose some precipitous coast where the rocks project in ledges, from which they can throw themselves into the sea if they are disturbed. Boldly-scarped cliffs, which rise perpendicularly from the waves, are consequently their favourite breeding-places. There it is necessary to seek them. Unfortunately, the demand for the wings and down of the Guillemots has reached a point which is not unlikely to lead to their extermination. One London dealer, we are told, has given an order at Ailsa Craig, on the Clyde, for a thousand sea-birds weekly; and the tacksman of the rock is so intent on supplying the demand, that he spreads his nets while the birds are sitting on the newly-hatched young, which are thus left in thousands to perish from being deprived of a mother's fostering care.
Among the Guillemots, the female lays only one large egg. They feed on fishes, insects, and crustacea. They principally 225 inhabit northern regions, visiting our shores and other temperate climates when the ice has invaded their summer home. In their migratory journeys they must trust to their wings—which, however, as already observed, are very short. They are consequently not possessed of long powers of flight, and skim the surface of the water, rarely rising much above the surface. Their progress, however, is sharp and rapid, but of short duration. The Guillemots during winter are frequently seen in immense numbers on Rock-all Bank and on the banks of Newfoundland. So little are they alarmed at the approach of a vessel, that should they be directly in her track, they will only dive to save themselves. These banks are several hundred miles from land.
The whole race of aquatic birds of which we have spoken, whether Divers, Penguins, Grebes, or Guillemots, are, in these northern regions, a valuable resource, where vegetation almost entirely ceases. The poor people whose lot compels them to live there obtain in their feathers, skin, oil, and eggs, clothing, food, and light during their long and gloomy winter. But to obtain what they truly consider a blessing from heaven, they have to surmount innumerable difficulties, the birds often building their nests in islets almost unapproachable, or on rocks rising perpendicularly out of the water. Slung upon seats hung from the summits of these crags, the courageous islanders suspend themselves, in the breeding season, to gather and make, so to speak, a harvest of the sea-fowls' eggs. Some of these men walk along the rocky coast, furnished with a conical net attached to the end of a pole, which enables them to secure the birds flying around them, much in the same manner as boys catch butterflies in the meadows.
But chasing these graceful swimmers at the foot of their rocky retreat is mere trifling; the dramatic and dangerous incidents occur at the summit of the steep, giant cliffs. The intrepid inhabitants of the Feroë Islands, which are situated to the north of Scotland, between Norway and Iceland, in the Atlantic Ocean, proceed as follows in the search after eggs. The fowler begins operations by swarming, as schoolboys call it, up a pole, which carries him to the first projecting ledge of the rocks. This point attained, he throws a knotted rope to his companions, who soon join him on 226 227 the aërial cliffs. The same manœuvre is performed, stage by stage, until they reach the summit. But this is nothing; he has now to visit the recesses in which the nests are to be found.
Upon the edge of the rock a beam is run out horizontally; to this beam a two-inch rope, which is not less than nine hundred feet in length, is attached. To the end of this immense line a plank is tied, upon which the fowler seats himself. This man holds in his hand a light cord for the purpose of signalling to his companions above. The fowler, thus seated, descends from cliff to cliff, and from rock to rock; he visits every nook and cranny in search of plunder, making an ample harvest of eggs and birds, either taking them by hand, or striking them with the end of his line. The product of his perilous expedition he places in a sort of haversack, which he carries slung from the shoulder. When he wishes to change his place, he gives a preconcerted signal with his cord, imparting an oscillating motion to it in the direction of that part of the rock he wishes to visit. When the harvest is deemed sufficient—when the day's sport is concluded—his companions are notified, and the fowler is hoisted to the summit of the cliff.
How incredible is the address, and how great the courage, required to induce a man to let himself be suspended by a slender cord over a precipice some hundreds of feet in height, and how hazardous, how frightful the peril! The cord might be cut by chafing against the sharp rock. What risks he runs on changing his place! It has sometimes happened to those above to hear one loud heart-rending shriek—the cry of despair. The men who hold the rope lean forward—they see nothing—they hear only the great voice of the sea, which drowns all other sounds as it breaks against the island. They hasten to draw up the cord—alas! its reduced weight too plainly tells what has happened! The fowler has been seized with vertigo; or, probably, he has overreached himself and lost his equilibrium on the slippery stones, and the wave which roars at the base of this wall of rock has closed over him.
It is such accidents as these which induce the inhabitant of the Feroë Islands, when he leaves his house on such an expedition, to bid farewell to his family. Fatal catastrophes, however, are not very frequent. Men who live in those climates which nature seems to have, as it were, disinherited, become accustomed 228 to struggle with the elements, and almost always to triumph over the dangers which surround them. They go to demand from the abyss food for their wives and children, and the idea animates and sustains their courage.

Individuals of this species are to be found dispersed over all our seas, in small parties or singly, during the interval between the breeding seasons. In estuaries, bays, and narrows, where herrings or other fry are abundant, they congregate in vast numbers, along with Auks, Red-throated Divers, and Gulls of various species. About the end of April great quantities may be seen flying in strings along the coast towards their favourite haunts, which are the precipitous cliffs of Flamborough Head, the Farn Islands, St. Abb's Head, and other well-known spots on the English and Scottish sea-board. No preparation is made for the reception of the eggs, which are deposited in hollows of the rocks and ledges of the cliffs, each female laying a single one, although a great number are often seen so closely packed together as to be possibly covered by one bird.
Where the cliffs are lofty and other birds breed with them, the Guillemot occupies a zone above the Kittiwake and below the Razor-bill. "It is interesting," writes McGillivray, with the enthusiasm of one who has tried it, "to visit one of the great breeding-places, to row along the foot of the cliffs in a boat, or to stand on a near promontory, and see the multitudes perched on the rocks, or flying out to sea or returning; or to look out from the summit upon the groups in sight; or startle from their stations a whole flock by letting down a large stone; or to descend by some crevice, clinging with fingers and unshod feet to the little narrow ledges, and creep in among the eggs; or to be let down, dangling on a rope, half trembling between fear and excitement." 229
Willoughby distributes the Palmipedes into such as have the back toe, and those in which it is absent; the former, again, into such as have the four toes webbed together, and such as have the back toe separated from the others. These latter he again subdivides into narrow-billed and broad-billed; the former having their bills either hooked at the end or straight and sharp-pointed. The hook-billed have them either even or toothed on the sides. Those which have them straight or sharp-pointed are either short-winged and divers—such as Doukers and Loons—or long-winged, such as Gulls. The broad-billed are divided into Ducks and Geese. The Ducks are either Sea or Pond Ducks. "The Ducks," he adds, "have shorter necks and larger feet, in proportion to their bodies, than Geese. Howbeit, the biggest in this kind do equal, if not exceed, the least in that. They have shorter legs than Geese, and situated more backward, so that they go waddling; a broader and flatter back, and so a more compressed body; and, lastly, a broader and flatter bill. Their tongue is pectinated, or toothed, on each side, which is common with them and the Geese."
"The Ducks are of two sorts, either wild or tame. The wild, again, are of two sorts:—1, Sea Ducks, which feed mostwhat in salt waters, dive much in feeding, have a broader bill (especially the upper one), and bending forward to work on the stem; a large hind toe, and then, likely for a rudder, a long train, not sharp-pointed. 2, Pond Ducks, which haunt plashes, have a straight and narrower bill, a very little hind toe, a sharp-pointed train, a 230 white belly, speckled feathers, black, with glittering green on the middle wing, with a white transverse ring on either side."
According to Mr. Yarrell, the first division of Ducks comprises the Wild Duck, Shieldrake, Muscovy Duck, Gadwall, Shoveller, Pintail, Widgeon, Bimaculated Duck, Garganey, and Teals, all of which exhibit length of neck, wings reaching to the end of the tail, tarsi somewhat round, hind toe free or without pendent lobe. They generally frequent fresh water, but pass much of their time on land, feeding on aquatic plants, insects, worms, and sometimes fish. The second division includes the Red Crested Duck, Poachard, Ferruginous Duck, Scaup, Tufted Duck, Harlequin Duck, Long-tailed Duck, and Golden Eye; while between the two divisions he places, as possessing some of the characters of each, the Eider Duck, King Duck, Velvet Duck, and Scoter.
McGillivray accepts this arrangement, with some slight variations, remarking that the differences as to habits, as well as structure, are quite obvious; and he gives us a graphic description of the three types. "High in air," he says, "advancing on gently-arched and outspread wings, that winnow a passage for them over the far-spreading sea, is seen advancing from the north a flock of large birds, that are observed, as they draw nearer, to be arranged in lines ever undulating and changing figure; while their clear cries seem to express their joy at having escaped the dangers of their long passage over the waste of waters. Now they descend, mingle their ranks, wheel in dislocated bands, unite, sweep along, and, clamorous in their joy, at length alight on the open pasture. Having rested awhile and plumed themselves, they begin to move about in search of food, walking sedately and with decurrent necks, stretching their strong bills to the ground, from which they wrench the roots of the grasses, and pluck the herbage. Prudent, however, as they well need be in an unexplored tract, and careful of their safety, they neither scatter about at random nor leave themselves subject to surprise. Should a suspicious object present itself, one of them presently erects himself and emits a warning cry, on hearing which they all rise together, raise their necks to their full stretch, and carefully inspect the ground. Should the danger be imminent, they run a few paces forward, spread out their large wings, ascend into the air, and betake themselves to 231 some distant place." These are of the first division, or Cribatores, as Mr. McGillivray calls them—more useful to man than the other aquatic birds, many of them not only affording him savoury food, but feathers, quills, and down; while some have become domesticated, and rival the Gallinaceous Fowls in utility: these are the Ducks and Geese of the poultry-yards and commons.
These web-footed birds, the Lamellirostræ of Cuvier, are distinguished from all others by their laminated bills, which are thick, have a covering of soft skin, also small teeth placed along the edge. The tongue is fleshy, broad, and dentated on the edge. They are aquatic, and principally inhabit fresh-water lakes and rivers. Their wings being short, and living chiefly on the water, they are badly qualified for a sustained flight. Their food is mostly vegetable.
Numerous flocks of Ducks, of various species, frequent the sea-shores and the rivers of all parts of the world. No family of birds seems more profusely distributed over the world of waters, and some of them are remarkable for the brilliant colouring of their plumage. On land, the waddling gait of Ducks is anything but graceful, but in the water their appearance is alert and elegant. Look at them as they glide lightly over the surface of the stream, or mark them as they plunge into its bosom with a splash, either to bathe themselves or seek their food! All their movements here are executed with graceful ease, and it is easy to see that they are in their natural element. They love to paddle in the mud, where they often find a sufficient supply of food to satisfy their voracity. But no description of animal matter comes amiss to them, whether water-insects, worms, slugs, snails, small frogs, bread, fresh or tainted meat, fish, living or dead. They are such gluttons, that we have seen two of them fighting and disputing for more than an hour over the skin of an eel, or some other garbage, which one of them had partly swallowed, whilst his antagonist was dragging at the other end. To this division of the Anatidæ belongs the Mallard, or Wild Duck, which may be considered typical of the others, and which is generally supposed to be the ancestor of the Domestic Duck. 232

Latin Synonym.—Anas boschas: Linn., Latham, Jenyns, Bonaparte, Temminck.

The plumage of the Wild Duck is dense and elastic. The head, throat, and upper part of the neck of the male are adorned with hues of a bright emerald green, shot with violet; its breast is of a purplish brown; its back is ashy brown, sprinkled with greyish-white zigzag bars; the four feathers in the middle of the tail, curling up at the end in a semicircle, are of a blackish hue with a green reflection; its length is about twenty-four inches; length of wing, thirty-five inches. The female, which is always smaller than her mate, does not possess the bright colours which adorn the Drake. Her plumage is brown and russet grey. Individuals sometimes, though seldom, vary. Sir William Jardine states that he has seen Drakes having the upper parts of a bluish grey, decreasing in depth of colouring down the breast; and Mr. Yarrell mentions two instances in which females of this species have assumed, to a considerable extent, the appearance and plumage of the Mallard, even to the curling feathers of the tail. On the other hand, the male plumage, according to Mr. Waterton, undergoes a singular alteration. About the end of May the breast and 233 back of the Drake begin to change colour; in a few days the curled feathers of the tail drop out, and grey feathers begin to appear in the lovely green plumage round the eyes; and, by the 23rd of June, scarcely one green feather remains. By the 6th of July all the green feathers have disappeared, and the male has assumed the female garb, but darker in colour. In August this new plumage begins to drop off, and by the middle of October the Drake again reappears in all the rich magnificence of its former dress.
The Wild Duck (Fig. 86) forms the original stock from which our Domestic Ducks have sprung. Their favourite resorts are to be found in those hyperborean regions whose rigorous climate renders it uninhabitable by man. The rivers of Lapland, Greenland, and Siberia are sometimes literally covered with them; and, in the month of May, their nests are there found in quantities which the imagination can scarcely picture. At the first approach of frost their earliest harbingers begin to appear among us, and about the middle of October these travelling bands arrive in increasing numbers.
Wild Ducks have a powerful, sustained, and rapid flight. With one stroke of the wing they raise themselves either from the land or water, and mount perpendicularly above the summits of the loftiest trees, when they take a more horizontal course, maintaining themselves at a great height, and making long journeys without rest. Triangular columns of them may sometimes be seen directing their unerring course towards their destination, the rustling of their wings being heard at considerable distances. The leading bird, which directs the course of the band, and which is thus exposed to the first resistance of the wind, from being foremost to cleave the air, soon becomes fatigued, when it falls back into the second rank, its place in the van being immediately taken by another (Fig. 87).
Wild Ducks are extremely suspicious in their nature. When they want to settle down on any spot, or to go from one pool to another, they sweep round in concentric curves, descending and ascending again and again, until they have made a complete survey of their intended halting-place.
The margins of fresh-water lakes, pools, and marshes are the principal localities frequented by the Wild Duck, so long as the 234 235 frosts of winter do not prevent their obtaining the water-insects and aquatic weeds on which they feed. But when the frost has congealed the stagnant waters, they take themselves off into more temperate climates, invariably following the course of the rivers and running streams. When they return northward after the great thaw—that is, about the end of February—they keep in pairs, and disperse themselves in search of breeding-places among the rushes, reeds, and sedge-grasses, constructing a bulky nest of weeds, which is simply placed on the ground, and generally near to water.
Much elegance is not to be looked for in the nest of the Wild Duck. A favourite situation is a thickly-growing tuft of sedge, and they content themselves with plucking off a few of the blades, the ends of which they bend down so as to form a foundation, the surface being covered with a soft layer of down. Their nests are occasionally found at some distance from the water, amidst heath or broom, or even in the fork of a tree, the female having been known to take possession of a Magpie's or Crow's nest which had been abandoned.
The Duck lays from five to ten eggs, and sometimes more; their colour varies, but is generally a dull greenish white. The female sits alone, and only leaves the nest to seek her food. When leaving her nest, she covers it up carefully with any rubbish at hand; on her return, the cunning creature alights a considerable distance from it, and glides through the grass, looking in every direction to see that she is not watched; if discovered, she will even feign lameness to induce pursuit, so that she may draw off intruders.
Incubation lasts about a month. The young ones are then hatched, all generally bursting the egg on the same day. They are covered with a close yellow down, and are quite alert when they leave the shell; and their mother soon leads them down to the water, encouraging them by her example to enter it. They do not return to the nest. At night their mother covers them under her wings, and at first feeds them with the small flies that come within her reach.
The ducklings, although they soon learn to swim, are unable to fly till after the expiration of three months; after that lapse of time wing-feathers are developed sufficiently to enable them to take flight. But they are always alert and active on the water, 236 diving and remaining under it for many minutes with nothing but the bill above the surface. When danger approaches, the mother utters a peculiar cry, and the young ones immediately conceal themselves. In a ditch full of water, Mr. McGillivray once came upon a whole brood of half-grown ducklings which disappeared in a moment; and although he searched everywhere for them, he did not succeed in finding a single one. When the Duck perceives the great Black-backed Gull, the ruthless enemy of her race, she beats the water with her wings as if to attract the attention of the aggressor. On his approach she darts at him with so much vigour that she compels him to retire, shamefully beaten.
Audubon relates a remarkable instance of maternal affection in this bird. The American naturalist had found in the woods a female of this species at the head of her young brood. As he approached, he noticed that her feathers became erect, and that she hissed with a threatening gesture, after the manner of Geese. In the meantime, the ducklings made off in all directions. His Dog, which was perfectly trained, brought the little creatures to him, one by one, without doing them the least injury. But in all his proceedings he was watched by the mother, who kept passing and repassing in front of him, as if to distract his attention. When the ducklings were all safe in the game-bag, in which they struggled and cried out, the mother came with a sad and troubled air, and placed herself close to the sportsman, as if unable to suppress her despair. Audubon, seeing her grovelling almost under his feet, was filled with pity, and restored her little family before leaving the spot. "When I turned round to watch her," adds the naturalist, "I really fancied I could detect an expression of gratitude in her eyes; and I experienced at that moment one of the most vivid sensations of pleasure I have ever enjoyed."
Whilst the mother is devoting herself to the education of her brood, the father pays but little attention to his progeny. Jaded and thin, he lives a solitary and quiescent life, more sad and wild than ever. He has, in fact, to submit to a most sudden course of moulting. The female also loses her plumage after the young ones are hatched. They neither of them regain their more brilliant dress until the end of autumn. 237

There are numerous instances proving that Wild Ducks are susceptible of attachment to man, and it is certain that they can be easily tamed. They also breed readily with the Domestic Duck; and the crossed birds thus produced are said to have an excellent flavour, and to fatten with facility. Mr. St. John, in his "Wild Sports in the Highlands," remarks that he has frequently caught and brought home young Wild Ducks. "If confined in a yard with tame birds for a week or two, they strike up a companionship which keeps them from wandering when set at liberty. Some years ago I brought home three, two of which turned out to be Drakes. I sent away my tame Ducks, and the next season I had a large family of half-bred and wholly Wild Ducks, as the tame and wild bred together quite freely. The Wild Ducks which have been caught turned out the tamest of all,—throwing off all shyness, they follow their feeder, and will eat corn out of the hand of any one they know; while the half-bred birds are inclined to take wing and fly away for the purpose of making their nests at a distance."
The flesh of the Wild Duck is much esteemed. But they are birds which are very difficult to approach, in consequence of their suspicious nature; and in order to get even a long shot at them, 239 it is necessary to have recourse to stratagem. Even when successful in your aim, the shot often fails to penetrate, owing to the thick layers of their downy covering. Various artifices, therefore, are employed to lure them, all of which require some cleverness. They are shot from a watching-place, being seduced to its neighbourhood by employing Domestic Ducks which act as decoys (Fig. 88). They are also shot from huts on the edge of the water. Sometimes they are attracted by means of lights, or by imitating their call. Many are taken in nets, in decoy-weirs, and in snares; they are sometimes even taken by means of baited fish-hooks, and many other strange contrivances.
The ordinary open Duck-shooting, as represented in Fig. 89, is far from being so productive as some of the former methods, but it is much more attractive. No sport is more uncertain, but occasionally none is more fruitful, or more full of unexpected successes.
Duck-shooting from a hut, as represented in Fig. 90, is the method most practised. The sportsmen are hidden in a small hut placed on the edge of some lake or river, or it may be erected in the middle of the water on a heap of stones. Here they lie in wait for the birds in order to get a close shot at them. They generally use fowling-pieces of great length and large calibre, called Duck-guns. Shooting from Duck punts is also practised all round the coast, and on the larger lakes, ponds, and estuaries.
On the Saône, the gunners, accompanied by a boatman, take their places in a long, light, narrow, pointed boat, or punt, called a fourquette. The two men, lying down in the bottom of the boat, are hidden by faggots placed in front of them, the muzzle of the duck-gun protruding through the faggots. Thus floating down the river among the Ducks, they get an opportunity of shooting them without being perceived. Sportsmen in France sometimes employ a very odd artifice to baffle the suspicious instinct of these birds: a man disguises himself as a cow by means of an outline of the animal roughly made of common cardboard. Under favour of this disguise he gets near the Wild Ducks without exciting their fears, if only aware how to make good use of his device; that is, if he describes gentle and graceful curves, so as to advance gradually without alarming the timid Palmipedes. But this sport, though productive enough when skilfully managed, 240 241 is not unattended with danger. A sportsman, who had dressed himself up in this disguise, happened inadvertently to find his way among a herd of cattle, which, detecting the imposture, immediately ran at him and chased him about the meadow. He thought himself fortunate in escaping with the loss of his disguise, which he abandoned to the fury of his horned assailants.
Large numbers of Ducks are taken by means of nets and various snares, which want of space prevents us from here enumerating.
The Domestic Duck, Anas domestica, is a descendant of the Wild Duck, or, as some think, of the Shoveller. The first tame Duck, the ancestor of a family since so prodigiously multiplied, probably proceeded from an egg which had been taken from some reedy marsh, and hatched under a Hen.
The Duck, however, has been reduced to a state of domesticity from a very remote period, and has been of incalculable utility to mankind, filling in our poultry-yards no unworthy place. Ducks' eggs are a wholesome and agreeable article of food, and the flesh of the bird itself is most savoury. Epicures highly prized, and rightly so, the pâtés de foie de canard of Toulouse, Strasbourg, Nérac, and Amiens (we arrange them here in their order of merit, not according to Baron Brisse's dictum, but following our own poor gastronomic capabilities). Their feathers, although not so valuable as those of the Goose, are articles of considerable importance in commerce.
Ducks produce large profits to those who rear them. They are by no means choice in their food. Nothing comes amiss to their palate; the corn scattered about the yard which is disdained by other fowls, and the meanest remnants of the leavings of the table and kitchen, they do not reject. All that they require as an essential is to have a little water within reach in which they can paddle at will.
Ducks' eggs are often put under a Hen to be hatched. When seeking her food, the Hen sometimes leads her little flock to the edge of water, and gives them a glimpse of its dangers. But the ducklings, impelled by instinct, rush into the element they are most partial to. The poor mother, anxious for the fate of the young giddy-pates, which she loves as her own offspring, utters cries of terror. She would resolutely throw herself into the stream, and perhaps get drowned, were she not soothed by seeing them 242 swimming about, happy and active. This shows her that in them she cannot recognise her own flesh and blood.
There are several favourite varieties of the Domestic Duck, but those of Normandy and Picardy, in France, and the Aylesbury Ducks in England, are the most profitable. Every nation rears Ducks; but the Chinese undeniably most excel in this art. For hatching them the Celestials have recourse to artificial heat. They also possess some superb varieties, which have been recently imported into Europe, and are at the present time the glory of our ornamental waters. Magnificent pairs of Chinese Ducks, of which the Mandarin is the most beautiful, may be admired in the Jardin d'Acclimatation at Paris, at the Zoological Gardens of the Regent's Park, and also in the artificial waters in the parks and gardens of our principal cities.
The Common Wild Duck, which we have described, is the type of the order of Ducks; but there are about seventy other species. The most remarkable are the Widgeon, the Poachard, the Shoveller, the Shieldrake, the Eider Duck, the Teal, the Black Diver, and the Merganser.

The Golden-eyed Garrot, Anas clangula, is sometimes called the Golden-eyed Duck, on account of the brightness of the iris of its eye. In some provinces it has received the nickname of the Harlequin Duck, because its plumage, at a little distance off, looks as if it was composed of black and white feathers only. This variegated appearance, which occurs only in the males, makes a fine show on the dark pools and lakes of the north Highlands and Hebrides, where the scenery in winter is excessively dismal. When undisturbed, they float lightly on the surface; but if alarmed, they are said to sink themselves deeper in the water, diving rapidly, and swimming with great velocity. They fly also swiftly in a direct manner, their small, stiff, and sharp-pointed 243 wings producing a whistling sound, which is heard in calm weather at a considerable distance.24 They rise easily from the water, striking it with their feet and wings for several yards; but under alarm, or when there is a breeze rippling the surface, they can ascend at once. During winter they are met with in all parts of the country, from Shetland and Orkney on the one side, and from the Lewis Islands on the other, to the southern extremity of England. In Ireland, also, they are constant winter visitors; but they do not seem to breed with us, betaking themselves to the Arctic regions in spring, and returning in October. They are essentially lake Ducks; but they are also found on the open coasts and estuaries. Their flesh is dark-coloured and unsavoury, it requiring all the art of the cook to conceal its natural fishy flavour.
They are generally plentiful in our markets, where the young and females go under the comprehensive name of Widgeons.
The Golden-eyed Garrot flies low and rapidly. In the month of November it reaches France in small flocks, to remain till the spring. Then it returns to its native country—Sweden, Norway, or Lapland. As it is not a shy bird, the sportsmen on the sea-coasts of Picardy, Normandy, and the Landes kill large quantities of them.

The Poachard nearly resembles the American Canvas-back Duck, but is unlike any British species in form. Its body (of the male) is large, full, depressed, and elliptical in form; its neck long and thick; the head large, oblong, compressed, and rounded above. The plumage is dense, soft, and glossy. The feathers on the fore part of the head are small and stiff; on the remainder of the head and neck soft, silky, and blended. The wings are short, curved, narrow, and pointed. The bill black to a little beyond the nostrils, the intermediate space light greyish blue. The head, and half the neck all round, are of a fine brownish-orange tint. 244
The Poachard (Fig. 91) is, next to that of the Common Wild Duck, the variety which is most plentiful on our waters. It is almost as large as the latter; it makes its nest in the rushes round pools or lakes, and feeds upon the roots of grasses and aquatic plants, also on worms, mollusks, and small fish. They are plentiful in the eastern counties south of the Humber, and in the fen counties; and it occurs in America, where, as Dr. Richardson states, it breeds in all parts of the fur countries, from the fiftieth parallel to their most northerly limits. Audubon found it abundant in winter about New Orleans, in East Florida, and in Chesapeake Bay. "Although they dive much and to a great depth in our bays and estuaries, yet, when in the shallow ponds of the interior, they prefer dabbling in the mud along the shores, much in the manner of the Mallard."
This bird reaches France in little flocks of twenty to forty in the month of October. It can easily be caught in nets.

French Synonyms.—Canard Souchet: Temminck. Rouge de Rivière: Figuier.
The Shoveller (Fig. 92) is very common on the Seine and the Marne, where it is called Rouge de Rivière. It is smaller than the Common Wild Duck, and has a very long bill, with the upper mandible of a semi-cylindrical shape, dilated at its extremity, 245 somewhat in the form of a small spoon. This bird is really charming in the brilliancy of its plumage. Its head and neck are of a bright green, and its wings are variegated with streaks of a brilliant pale blue, green, white, and black. It is called "red" because its plumage underneath is of a brownish-red hue. In the month of February it abandons the icy regions of the north, to visit the more southern lakes and rivers of France and Germany. With us it is only a straggler, although in former days, when our system of drainage was less perfect, it was a more frequent visitor. In France considerable numbers of the Shovellers remain and breed. It dwells in marshes, on lakes and large rivers, being seldom found near the sea-coast; feeding occasionally on vegetable substances, but chiefly on fresh-water mollusks, worms, and insects, for grubbing up which, and separating them from the sand and mud, its bill is evidently well adapted.
The Shoveller is met with in various parts of Europe, as well as in Asia, Africa, and America, where it is found widely dispersed. The nest is constructed on the borders of rushy lakes, and they lay from eight to twelve eggs. When first hatched, the young ones are excessively ugly, their beaks being almost as large as their bodies. The flesh of the Shoveller is tender and delicate, and preserves its pink colour even after it is cooked. 246

This very beautiful bird is a permanent resident in the British Islands, although it is only met sparingly along our coasts. It resorts in spring and summer to the sandy bays on the west coast of England and Scotland, from the Land's End to the Shetland Islands. In autumn and winter it is found on the eastern coast both of Scotland and England, where many individuals remain to breed. It is generally found in the neighbourhood of sandy, marshy land and moist meadows near the sea. It walks with a quickish step, and has a swift flight, something like the Mallard, and with a more rapid beat of the wings than the Goose.
The Shieldrake (Fig. 93) is the most remarkable of all the 247 Duck tribe, not only from its size, but from its beauty, and the elegant variations of its plumage. It is larger and stands higher on its legs than the Common Wild Duck. The plumage is full, soft, and blended; the feathers of the head and upper neck are small and silky. The colours are very brilliant, being of a glossy blackish green on the head and neck, with purplish reflections in some lights; a broad band or ring of white is found on the neck, and lower another of orange-red encircles the fore part of the body. The rest of the under parts are white, with a band of glossy black on the breast and belly; the back white, variegated with black, white, russet, and green. The Shieldrake abounds on the coasts of the Baltic and North Sea; it is also found in America, and on the southern coasts of France, as well as on the edge of the Northern Ocean. The nest is usually placed in some indentation in the sand, the female frequently choosing a Rabbit's hole, which is often situated in sand-banks. The poor Rabbit, thus turned out of its burrow, never ventures to return to it again.
English Synonyms.—Eider Duck: Montagu. Common Eider: Selby. White-backed Eider: McGillivray. Popular names: St. Cuthbert's Duck, Dunter Goose.
Latin Synonyms.—Anas mollissima: Linn., Latham, Temminck. Somateria mollissima: Jenyns, Bonaparte, McGillivray, Selby.
The Eider Duck, though remarkable for beauty of plumage, is nevertheless a very clumsy bird. In form it is bulky, depressed, and elliptical, with large, oblong, and compressed head. The plumage is dense and fine; the head-feathers are short, tufted, and rounded, and, blending with the terminal filaments, disunited; the wings diminutive, concave, narrow, and pointed, the tips of which extend to the base of the tail, which is short, round, and slightly decurvated.
The Eider Duck is the northern bird which supplies the soft, light, and warm material which is so well known under the name of "eider-down." Its plumage is whitish, but the upper part of the head, its belly, and its tail are black; the side of the head, the throat, and the neck are white, but the hair-like feathers on the back part of the cheeks and nape are of a delicate pale green; the 248 lower part of the neck is cream-coloured. The black parts from their glossiness are conspicuous, while the white look soiled; the head and back are also shaded with a green tint.
The Eider Duck is found in the Arctic and Antarctic regions, occurring in diminished numbers in the latter. In the Outer Hebrides it has many breeding-places, and some nests occur on the Bass Rock, and on the Farn Islands, off the coast of Northumberland, where the eggs have been found in the month of June. The nest is made in some hollow in the turf, and is composed of sea-weed and dried grass, mixed with such marine plants as Plantago maritima and Coronopsis. The eggs, which vary in number, are of a longish oval shape, smooth and glossy, and of a pale greenish grey. When they have been laid, the female is said to pluck the down from her breast and cover them over with it. This down, when shaken out, will occupy a space of nine or ten inches. This peculiar quality of the down, however, caused by its elastic character, belongs to all the Anatidæ, and probably not less so to the Anserinæ.
The principal home of the Eider Duck is on the bleak and frozen sea-coasts of Northern Europe, and its food, which is obtained by diving, is the bivalve mollusca; also crustacea, fishes, and fish-spawn, together with aquatic worms. It makes its nest on rocks washed by the sea. Sometimes two female birds lay in the same nest, which then contains from nine to ten eggs, for each of them lays from four to six. The nest is roughly built with sea-weed, but it is lined inside with a thick layer of the bird's own down. "The Eider Ducks," as we learn from Willoughby, "build themselves nests on the rocks, and lay good store of very savoury and well-tasted eggs; for the getting of which the neighbouring people let themselves down by ropes dangerously enough, and with the same labour gather the feathers, or eider-dun, our people call them, which are very soft and fit to stuff beds and quilts; for in a small quantity they dilate themselves much, being very springy, and warm the body above any others. These birds are wont at set times to moult their feathers, enriching the fowlers with this desirable merchandise." "When its young are hatched," adds the English naturalist, "it takes them out to sea, and never looks at land till next breeding-time, nor is seen anywhere about our coasts." 249
There seems to be some considerable difference between the down taken from the dead bird and that which the female plucks from her breast. The lightness and elasticity of the latter are such that two or three pounds of it squeezed into a ball which may be held in the hand will expand so as to fill a quilt large enough to cover a bed. When the female prepares her nest, she lines it as above mentioned; when she has laid her four or six eggs, which are about three inches in length and two in breadth, she strips herself a second time; should this down be abstracted, as it generally is, and she is unable to supply more, the male submits himself to the same plucking process, his contribution being known by its paler colour.
The haunts of a bird yielding so valuable an article are carefully watched, and proprietors do everything in their power to attract them to their land; and in Scotland and Norway the districts resorted to by the Eider Ducks are strictly preserved, everything likely to disturb them being carefully guarded against. Pennant thus records a visit he paid to one of their breeding-places in the Farn Islands on the 15th of July, 1769:—"I found the Ducks sitting," he writes, "and I took some of the nests, the base of which was formed of sea-plants and covered with the down. After separating it carefully from the plants it weighed only three-quarters of an ounce, yet was so elastic that it filled a greater space than the crown of the largest hat. These birds are not numerous on the isles, and it was observed that the Drakes kept on the side most remote from the sitting-places. The Ducks continue on the nest till you come almost to them, and when they rise, they are very slow fliers. The eggs are of a pale olive colour, large, glossy, and smooth; they are from three to four, warmly bedded in down." Sir George Mackenzie, in his "Travels in Iceland," says that "the boat in its approach to Vidöe passed multitudes of Eider Ducks, which hardly moved out of the way; and between the landing-place and the governor's house it required some caution to avoid treading on the nests, while the Drakes were walking about even more familiar than common Ducks. The Ducks were sitting on their nests all round the house, on the garden wall, on the roof, in the inside of the house, and on the chapel."
The locality where the Eiders make their nests is always difficult 250 of access. Nevertheless, the inhabitants of Iceland, Lapland, and the coasts of the North Sea invariably secure them. The harvest which is derived from these birds is the source of a considerable revenue, eider-down being, in fact, a very large article of commerce. The rocks where the Eider Ducks lay their eggs are private property, and are handed down in families just as if they were the most valuable possessions.
English Synonyms.—Common Teal: Montagu, Selby. Green-winged Teal.
Latin Synonyms.—Anas crecca: Linn., Latham, Flemming, Temminck, Jenyns. Querquedula crecca: Bonaparte, Selby, McGillivray.
French Synonym.—Canard Sarcelle.
This is the smallest of the Duck kind known in the British Isles. It is a remarkably beautiful bird, and in colouring as well as in form closely resembles the Mallard, but is much smaller. It frequents marshy places and the margins of lakes and rivers, seldom betaking itself to estuaries or the sea-coast until frost sets in. It walks with ease, swims with great dexterity, flies rapidly, and is in all respects remarkable for its activity. It rises from the water or the land at once, and shoots away with great rapidity, so that the marksman who would bring it down must be very expert with his gun. It breeds in the long reedy grasses on the margin of lakes, or on upland moors and marshes. Its nest 251 is a mass of decayed vegetable matter lined with down and feathers, in which it lays ten or twelve eggs, about an inch and three-quarters in length and an inch and a quarter in breadth. North of the Tay they are found occasionally all the year round, returning, according to Mr. St. John, year after year to breed, if left undisturbed in the process of incubation.
"If we compare," says Mr. McGillivray, "the Common Teal (Anas crecca, Linn.), with the Garganey (Anas circia), the Gadwall (Anas strepira), and the Pintail Duck (Anas acuta), we find slight differences in the form of the bill, in the elongated lamella of the upper mandible, in the length of the neck and tail; but they are all so intimately connected that, unless each species can be converted into a genus, there can be no reason for separating them." He classes them accordingly under the general name of Teal.
This bird makes its appearance in France in spring and autumn. It breeds in all the temperate climates of Europe, and pushes on towards the south as the winter advances.
Of the Teals there seem to be three, probably four, species, which in our climate may be divided into three—namely, the Common Teal, Anas crecca; the Summer Teal, Anas circia; and the Little Teal, or Black Diver, Anas nigra.
According to Columella, in his work "De Re Rustica," the Romans succeeded in domesticating the Teal; but the bird has reverted to an entirely wild state, which is much to be regretted, for it would have formed a valuable addition to the poultry-yard, the flesh of the Teal being held in great estimation.
The group of Ducks usually denominated Teal, Mr. Swainson has formed into the sub-genus Boschas, in which he also includes the Mallard, or Wild Duck. "As this is the most numerous group," says this writer, "so it exhibits a greater diversity of form among the species. They are all, however, characterised by a bill longer than the head, whose breadth is equal throughout; sometimes indeed a little dilated, but never contracted at the tip, while the laminæ of the upper mandible are entirely concealed by the margin of the bill." "The beautiful Anas formosa, which is essentially a Teal, differs," says a writer in the "Penny Cyclopædia," "in the greater length of the tail, thus connecting it more closely with the Pintail and other long-tailed species; 252 while the bill, which is depressed in form in the Mallard as well as in the Common Duck, is convex, with projecting laminæ, in the Teal. Such is the case with the Blue-winged Teal of North America, in which the laminæ of the upper bill project nearly as much as in the Gadwall, while the upper mandible exhibits that sinuosity at the base which is seen in no other Duck except the Shoveller."
Mr. Selby says of the Common Teal: "I am inclined to think that our indigenous breeds seldom quit the immediate neighbourhood of the places in which they are bred, as I have repeatedly observed them to haunt the same district from the time of their being hatched till they separated and paired on the approach of the following spring. The Teal breeds in the long rushy herbage about the edges of lakes, or on the boggy parts of upland moors." Very few of them are found, according to Mr. McGillivray, in the south of Scotland during the summer months. In winter, one of his correspondents informs him, it unites in large flocks, the Drakes having then a whistle like the Plover; but it has not been heard to use this call during the breeding season. The boldness of the female in defence of her young is very affecting. Mr. St. John describes an instance which occurred in Ross-shire. He was riding along when an old Teal, with eight newly-hatched young ones, crossed the road. The youngsters could not climb the bank, and all squatted flat down while he passed. He dismounted, and carried all the young ones a little distance down the road to a ditch, the old bird fluttering about all the time, and frequently coming within reach of his whip. The part of the road where he found them passed through a thick fir-wood covered with rank heather, and it was a great puzzle to him how such little things, scarcely bigger than a mouse, could have struggled through it. Next day he saw them all enjoying themselves in a pond a little distance off, where a brood of Teal appeared every year.
Teal are less timid than the Wild Duck, and the sportsman, therefore, has not the same difficulty in getting within shot of them. They breed in great numbers in some of the Highland lochs, and Mr. St. John says that in August he has seen perfect clouds of them rise from some calm, glassy lake at the report of a gun. 253
English Synonyms.—Velvet Duck: Montagu. Velvet Scoter: Selby, Jenyns, McGillivray. Black Duck, White-winged Black Duck, Black Diver, Double Scoter.
Latin Synonyms.—Anas fusca: Linn., Latham, Temminck. Oidemia fusca: Selby, Jenyns, Bonaparte, McGillivray. Anas nigra: French writers.
French Synonym.—Canard Macreuse: Temminck.
The Scoters (Oidemia, Flemming) have the bill broad, with dilated margins, and coarse lamelliform teeth; a swelling above the nostrils, dividing them into two equal parts, both large and elevated.
The Velvet Duck is the largest of the Scoters, and is distinguishable by the white band upon its wing, much-depressed body, thick neck, and large, oblong, and compressed head. They make their appearance in our bays and estuaries towards the end of autumn, and depart about the middle of April. In the evening they fly out to sea in flocks of fifteen or twenty when the weather is favourable, returning to the shore in the morning. They fly low, but with considerable speed, moving their wings quickly; and on arriving at a suitable place, they relax a little and alight on their hinder end, the body being kept oblique. On settling, they commence forthwith to feed.
English Synonym.—Black Scoter: Selby, Jenyns, McGillivray.
Latin Synonyms.—Anas nigra: Linn., Latham, Temminck. Oidemia nigra: Flemming, Selby, Jenyns, Bonaparte, McGillivray.
The Black Scoter arrives on our shores about the middle of autumn in considerable flocks, and is seen on all our western coast during winter, but is still more abundant on the French coast. It closely resembles the American Scoter, of which it is probably a variety.
The Black Scoter (Oidemia nigra) is almost as large as the Common Wild Duck, but is shorter and more thickly made. Its plumage is entirely black; when young it is greyish.
The Black Scoter passes its life on the surface of the water, and 254 never ventures on the land except when driven by stress of weather, or for the purpose of making its nest in the marshes. It flutters rather than flies over the surface of the sea, and makes no use of its wings, except to escape some danger, or to transport itself from one point to another with more rapidity. Its legs, in flying, hang down, and constantly graze the surface of the water; it always appears as if it regretted to leave its favourite element.
When on land, these birds walk slowly and ungracefully; but in the water they are never wearied. Like the Petrel, they have the singular faculty of being able to run about on the waves. They are natives of both the Old and New World. About the month of October, driven by the north and north-west winds, they come down from the northerly countries of Europe, and visit our Atlantic coasts and the Mediterranean.
The Black Scoter delights in the salt-water pools adjacent to the sea, and the sheltered creeks on the coast, in which they find a refuge against storms. In these places they become the objects of the terribly destructive sport of which we are about to speak.
Two or three times during the winter, large placards exhibited in certain towns of the department of Hérault—at Montpellier, Cette, Agde, &c.—announce that large flocks of these birds (called foulques in the country) having settled down on some adjacent lake, a day's sport will be had with them on a given date. The day is turned into a real fête by the sportsmen, and an extraordinary concourse of people are brought together. Every one starts in the middle of the night, some in carriages, some in carts, and the most humble among them on donkeys or on foot. At daybreak they reach the margin of the lake. When arrived there, they embark in boats, each provided with a rower. At a given signal the whole flotilla puts off from the shore, and advances slowly towards that part of the lake in which the Ducks are to be found.
These unusual preparations are a cause of astonishment to the 255 birds, which utter gentle cries of terror as they crowd together. The boats, however, hem them in on all sides, gradually contracting their circle so as to shut the birds up in an enclosed space. The Black Scoters, seeing the enemy advancing upon them, in their anxiety take to diving and plunging about. But, before long, being closely pressed, they spread their wings and take flight over the heads of their enemies. This is the signal for the commencement of the first volley. There is now no cessation in the resounding reports of the guns; for usually no less than five hundred sportsmen meet on the surface of a not very extensive lake, such as those of Mauguio or Palavas. The massacre lasts for some hours; in fact, these unfortunate birds, incapable of flying very far, are pursued from place to place by the pitiless boats, which are soon, like the bark of the venerable Charon, laden with the dead. When no birds remain on the lake, the boats return to the shore, rowing along the banks to hunt out the wounded. Three thousand of these birds will sometimes fall before the murderous guns in the space of a few hours. Almost as a matter of course, quarrels often arise among the sportsmen. The cause of dispute may be some bird which has been shot at from several boats at the same moment. These disturbances, which usually begin with shouts and abuse, from the warmth of the southern blood sometimes terminate fatally. In this sport tumult reaches its utmost pitch, and it is as productive of danger as of pleasure. Sometimes a boat capsizes, owing to the excessive eagerness of the rowers; sometimes a sportsman is wounded by an awkward neighbour, or two or three men fall into the water in trying to reach their prey. Such are the exciting scenes that I have often witnessed in my youth; they were the supreme delight of the boys of Clapas (Montpellier). The same sport is practised at Hyères, in the Var, and on the lake of Berre, near Marseilles.
On the coasts of Picardy, where the Black Scoter abounds during winter, very destructive means are used for their capture. Nets are stretched horizontally in the water, above the banks of shell-fish which the sea has left uncovered at its reflux, and on which these birds feed. When they dive to seize their prey they become entangled in the meshes of the net, from which they cannot escape.
The Black Scoter is also the object of individual sport when it 256 does not arrive in these immense flocks. It is then shot from a boat like other water-fowl.
The Black Scoter makes but a poor figure on aristocratic tables. Its flesh, which is by no means tender, retains a very decided marshy flavour. In former times it was much sought after, but not exactly for its culinary qualities. The reason this bird was shown such preference was because people were permitted to eat it in Lent in place of fish.
The singular notions on which the Church of Rome founded this toleration—a toleration, however, which still exists in full force even at the present day—is as follows. The councils of the twelfth century permitted both the clergy and laity to eat Black Scoters during Lent because it was a generally-accepted idea, founded on the writings of Aristotle, that these birds were not produced from an egg, but had a vegetable origin. The learned of the Middle Ages and the Renaissance, seeing large flocks of these birds suddenly appear, while nothing was known whence they came, indulged in all kinds of conjectures to explain this mysterious fact. They attributed to them origins which were marvellous; one conjecturing that the feathery appearance in the ciliated tentacles of certain mollusks which inhabit the barnacle shell changed into Black Scoters; others imagined that these birds proceeded from the wood of rotten fir-trees which had been long floating about in the sea, or even from the fungi and marine mosses which cling to the débris of wrecked ships; others, again, went so far as to assert that the north of Scotland, and especially the Orkney Isles, produced a tree the fruit of which, falling into the sea, developed into the bird which was called Anser arboreus, in order to commemorate its origin: this bird they imagined was the Black Scoter.
The naturalists who gave expression to these transcendental views might certainly boast that they had Aristotle on their side; for this distinguished philosopher believed in the spontaneous generation of various kinds of animals. He asserted, for instance, that rats sprung from decayed vegetables, and that bees proceeded from the carcass of an ox. Who, for instance, is unacquainted with the fine episode of the fourth book of Virgil's Georgics, where this poetic fiction is related in beautiful verse? 257
As a matter of fact, however, Pope Innocent III., better instructed than Aristotle in this department of natural history, passed sentence on all these tales by forbidding its use during Lent; but no one, either in the monasteries, the castles, or the taverns, has ever looked at this interdict of the sovereign pontiff in a serious point of view.
This controverted question, however, met with an unexpected solution. Gerard Veer, a Dutch navigator, in one of his voyages to the north of Europe, found some eggs of the Velvet Duck. Being ignorant of their nature, he brought them home, put them under a hen, and, when they were hatched, the produce exactly resembled the birds which were asserted by the ancients to proceed from the decay of vegetable matter. Gerard Veer made the announcement that these birds bred in Greenland, thus affording a complete explanation of the absence of their eggs in southern countries.
This discovery of the Dutch navigator met with no favourable reception. The custom of eating the Velvet Duck in Lent had been long established; the Church allowed it, and every one was satisfied. Gerard Veer was sent back to his galliot, and all kinds of reasons were found for satisfying the consciences and stomachs of the faithful, which had been justly alarmed.
There was, however, no deficiency in the arguments brought forward. It was asserted that the feathers of the Velvet Duck were of quite a different nature from those of other birds; that their blood was cold, and that it did not coagulate when shed; that their fat, like that of fishes, had the property of never hardening. The analogy between the Velvet Duck and the fishes being thus clearly established, the permission of the councils remained in full force.
Finally, as the writers of the Middle Ages and the Renaissance were but indifferent naturalists, and had very vaguely described the Velvet Duck, the same mode of reproduction was ascribed to several other marsh-birds. As a matter of course, the same toleration in Lent was extended to them. The faithful were thus in the habit of indulging in various other birds, such as the Brent and Bernicle Geese. The opposing claims of devotion and appetite being thus harmlessly satisfied, no one 258 cared to object to a supposition which gave such general satisfaction.
We must add that this confusion of names still exists, for on the sea-coast several varieties of the Duck genus still go by the name of the privileged bird.
There are five principal varieties of this species. The most remarkable are the Velvet Duck (Oidemia fusca), the Common Black Scoter (O. nigra), and the Great-billed Black Diver (O. perspicellata).
English Synonyms.—Surf Scoters: Selby, McGillivray, Jenyns. Surf Duck, Black Duck: Pennant.
Latin Synonyms.—Anas perspicellata: Linn., Latham, Temminck. Oidemia perspicellata: Selby, Jenyns, Temminck, McGillivray.
French Synonyms.—Macreuse à large bec, Canard marchand.
The Great-billed Scoter is a rare bird in this country, the only positive evidence of its occurrence being a female, shot in the Firth of Forth, mentioned by Mr. Gould, and a recently-shot specimen sent to Mr. Bartlett for preservation, and from which Mr. Yarrell derived his description. It is, however, stated by Audubon as being abundant in winter on the eastern coast of America, as far south as the mouth of the Mississippi. In Labrador he found a female on its nest in a marsh; the nest was snugly placed amidst the tall blades of a bunch of grass, and was raised fully four inches above the roots. It was composed of withered and rotten weeds, the former being circularly arranged over the latter, producing a well-rounded cavity, six inches in diameter, and two and a half deep; the border of the inner cup being lined with down from the birds after the manner of the Eider Duck. In it lay five eggs, the smallest he had ever seen in a Duck's nest. They are equally rounded at both ends, about two inches and a half long, and an inch and five-eighths in their greatest breadth; the shell perfectly smooth, and of a uniform yellow colour.
The plumage of the bird is soft, dense, and glossy; the feathers of the head and neck blended and velvety; the wings short, narrow, and pointed; the upper mandible orange red, the protuberance on each side yellowish grey; at the base is a large square 259 patch of black, margined with orange red, with a patch of greyish white in front.
Intimately allied to the Ducks in many respects, and to the Divers and Cormorants in others, are the Mergansers, a very distinct family, characterised by a large, elongated, and depressed body; long and slender neck; oblong, compressed head, narrowing anteriorly; bill straight, narrow, and slender, sub-cylindrical outwards, wide at the base, and abruptly hooked at the tip; margins of both mandibles serrated; the teeth directed backwards.
English Synonyms.—Goosander: Montagu, Selby, Jenyns. Dun Diver: Montagu. Buff-breasted Goosander: McGillivray. Greater Goosander, Saw-bill, Jacksaw.

The Merganser (Mergus, from mergere, to submerge) is sometimes separated from the Ducks. Prince Charles Bonaparte includes in it two sub-genera, the Smew (Mergus) and the Merganser of Leach. The Merganser is distinguished by its slender and almost cylindrical bill, armed on the edges with points turning backwards, somewhat resembling the teeth of a saw; yet, in its general appearance, plumage, and habits, this bird bears much resemblance to the Ducks.
The Mergansers very rarely come on land; they are exclusively aquatic, and frequent rivers, lakes, and pools, preferring them to estuaries; but they may be seen in summer fishing in the sea-lochs of Scotland. The Latins gave them the name of Mergus in consequence of their habit of swimming with the body submerged—the head only appearing above the surface of the water.
These birds feed on fish, of which they destroy an immense number. They also commit serious depredations on the spawning beds. They are able to accumulate a large quantity of air in the trachea, and can therefore remain some time under water without breathing. They take advantage of this for diving to the 260 bottom to seek their prey, and they will often travel to a considerable distance before they appear again on the surface. The activity they display in pursuit of their prey is very great; for, in order to accelerate their speed in swimming, they make use of their wings as well as of their feet. The Merganser is in the habit of swallowing fish head first; consequently, it often happens that the remainder of the body of their prey is too bulky to be easily gorged; they are, however, very far from wishing to get rid of this temporary inconvenience, but wait till it becomes gradually absorbed. Sometimes the digestion of the fish's head has already commenced in the bird's stomach whilst the tail is still projecting from its bill.
The flight of the Merganser is rapid and prolonged, without reaching any great elevation. Their gait on land is awkward and tottering. They generally inhabit temperate regions during the winter, and in spring return to the high latitudes of both hemispheres, which are their breeding-places. They lay from eight to fourteen whitish-coloured eggs, either on the shore between two large stones, or in thickets of grass on the edge of lakes and rivers: occasionally a hollow in a tree is selected; but it is invariably near water. Their nest is composed of dry grass, sedges, fibrous roots, and other similar materials, with a lining of down plucked from the breast.
The Merganser is a regular visitor, in winter, to our coasts and inland lakes. It breeds in North Uist and others of the Outer Hebrides. Its flesh is unedible except when young.
English Synonyms.—Smew: Montagu, Selby, Jenyns. Pied Smew: McGillivray. White Nun: Selby. Pied Diver, Vane Widgeon.

Like its congeners, the Smew is a native of the northern regions of both continents, retiring southward as the winter approaches, and spreading in great numbers over Germany, France, and Italy in October and November, and returning northward in April. 261 North of the Humber it is a rare bird. Montagu says it is plentiful on the south coast, but that it is not known to breed with us. It is of elegant form, smaller than the Merganser, being only fifteen inches in length. The plumage of the head is full, soft, and blended; the upper part of the head and nape elongated, forming a gradually narrowing crest; the wings short, rather narrow, slightly convex, and pointed—when closed reaching to within an inch and a half from the end of the tail. The male bird, at maturity, has a great spot of greenish black on each side of the bill, and a longitudinal one on the occiput. The tufted crest, neck, scapulars, small coverts of the wing, and all the lower parts are pure white; the upper part of the back, the two crescents under the sides of the breast, and the edges of the scapulars are deep black; the tail is ash-coloured; sides and thighs are varied with ash-coloured zigzags; bill, tarsi, and toes are bluish ash; webs black, and the iris brown. In habit the Smew greatly resembles the Goosanders.
The Goose (Anser) forms a special genus among the Palmipedes. It is a bird which is often spoken of with contempt, though very improperly, for few birds are able to afford mankind the amount of service rendered by the despised Goose. 262
English Synonyms.—Grey Lag Goose: Montagu, Selby. Wild Goose: Jenyns. Marsh Goose, Grey Lag, Grey Goose, Fen Goose.
Latin Synonyms.—Anas anser: Linn., Latham. Anser ferus: Temminck, Jenyns, McGillivray. Anser palustris: Selby. Anser cinereus: Bonaparte.
French Synonym.—Oie Cendrée: Temminck.
The Wild Goose, though by no means elegant in form, has none of the awkwardness of the Domestic Goose, which is generally supposed to be descended from it. The body of Anser ferus is large and full; the neck long, at its upper part slender; the head proportionately small, ovate, oblong, and rather compressed; the feathers of the head are small, short, rounded and blended, of a greyish brown; those of the upper part of the neck small and oblong, and arranged in ridges with deep intervening grooves, gradually getting paler until it fades into greyish white; the wings are long, reaching nearly to the end of the tail, the feathers of the fore part of the back and wings close, broad, and abrupt; the prevailing colour a bluish grey.
The Geese in many respects resemble the Ducks and Swans, but they are less aquatic in their habits, keeping at a distance from large bodies of water, and frequenting, by preference, moist meadows and marshes, where they find herbage and various kinds of seeds, on which they principally feed. They swim very little, and seldom dive. They make their nests on the ground, and lay from six to eight eggs, which are hatched in rather more than one month. The young ones walk about and find their own food almost as soon as they are hatched. Geese, especially the male birds, moult twice a year—in June and November.
The noise made by a flock of Geese seeking their food can be heard at a great distance. Their call, which is repeated at regular intervals, somewhat resembles the sound of a trumpet or clarion, and is accompanied by a continuous muttering noise in shorter notes. The hissing common to both Geese and Ducks is produced by two membranes placed in juxtaposition at the lower part of the trachea. These two membranes are situated side by side in the two bony and elongated openings of the internal larynx, 263 from which the two principal bronchia have their origin. A close examination of this organ in the Goose is supposed to have contributed to the invention of certain wind instruments, such as the flute, bassoon, bagpipes, clarionet, and even the organ.
When attacked, the Goose makes a hissing noise similar to that of some serpents. Endeavours have been made to express this sound by the three Latin words strepit, gratitat, stridet. The slightest noise wakes them up, when they at once give the signal of alarm, which immediately warns the whole flock of approaching danger. Thus, some authors have maintained that the Goose is more vigilant than the Dog; and in proof of this, instance the story of the Geese of the Capitol, whose wakefulness saved the Romans from an attempted assault on the part of the Gauls. The Roman people were grateful enough to award an annual sum for the maintenance of a certain number of Geese in the Capitol; and on the anniversary of the day when their services had been so valuable, they were in the habit of whipping the Dogs in front of the building, as a retrospective punishment for their culpable carelessness.
The Gauls, on the other hand, never pardoned the Goose for having baffled their attack. Frenchmen, even in the present day, possibly the descendants of the proud companions of Brennus, or of the conquerors of Northern Italy, appear still to inherit this ancestral hatred. At some of the French village fêtes they are in the habit of hanging up Geese by the feet in order to cut through their necks with a sword, or to beat them to death by hurling 264 stones and sticks at their heads. At every blow the poor creature must suffer dreadful agony, but it is left in its pain until it dies a lingering death. It is then borne away in triumph by the conqueror, and its mutilated carcass afterwards appears at his table to be devoured by him and his companions. Happily, the Assemblée Nationale has now forbidden this brutal and sanguinary amusement as being dishonourable to a civilised nation.
It is difficult to say why the Goose should have been considered, from the earliest ages, as the symbol of stupidity. Their sight is sharp and piercing, and they enjoy a remarkable delicacy of hearing. Their sense of smell, moreover, may be compared to that of the Crow. Their watchfulness seems never at fault. When they either sleep or eat, one of their number is placed as a sentinel. With neck stretched out and head in the air, it scrutinises the distant horizon in every direction, ready, at the slightest alarm, to give a signal of danger to the rest of the flock.
The flight of Wild Geese indicates no slight degree of intelligence. They place themselves in two slanting lines, forming a < shaped angle, or sometimes in a single line, if the flock is not very numerous. This arrangement allows each bird to follow the main body with the least possible amount of resistance, and at the same time to keep its rank. When the individual which leads the flight begins to be fatigued, it takes its place in the rear, each bird in its turn leading the flock.
These birds are too numerous to travel in large flocks; it would appear, therefore, as if they fixed upon some points where they separate in order to distribute themselves over various countries. In Europe Wild Geese come principally from Asia. On their arrival here, the flocks disperse themselves over different districts. In our land they make their appearance towards the beginning of winter, and depart towards the end of April. Formerly they are said to have been abundant, and to have been even permanently resident; now they are rare, and are seldom known to breed with us. On their arrival they resort to open pastures and cultivated fields, feeding on the roots of aquatic grasses, young corn, clover, and other green herbage. On an alarm being given by the sentinel on watch, they all erect their necks, run forward, and, uttering their loud, grating cry, spring into the air, departing with a heavy, 265 measured, and lofty flight. According to Temminck, "the Wild Goose inhabits the seas, coasts, and marshes of eastern countries, seldom advancing northward beyond the fifty-third degree; it is abundant in Germany and in Central Europe; occasionally, in its migrations, it halts in small numbers in Holland." Those which visit France are the harbingers of the frost; and when they make an early appearance, it is well known that the winter will be a severe one.
Although they live little in the water, Wild Geese repair every evening to the ponds and rivers in their neighbourhoods to pass the night; so that the Wild Goose only takes to the water when the Wild Duck is leaving it. These birds are very difficult to shoot in consequence of their lofty flight, from which they only descend when they see the water on which they are to pass the night. Even then their excessive caution renders nearly useless all the stratagems of the sportsman. The attempt is sometimes made to take them in the evening with nets, the wild ones being attracted by means of tame Geese, which are trained to act as decoys.
The Ostiacs, on the banks of the Obi, in Siberia, pile up the snow, and, with the addition of branches, construct small huts. Near these they place some stuffed birds in the water; the Wild Geese dart on these and peck them to pieces. While thus busily occupied, they can easily be shot or taken with nets.
But the most curious and difficult mode of capturing them is that followed by the adventurous inhabitants of St. Kilda, a little islet on the west coast of Scotland. Wild Geese of several species make their nests there in large flocks at the foot of the sea-washed rocks which surround the island. It is very doubtful if the Wild Goose, Anser ferus, is found among these. Both for strength and economy, the inhabitants use a cord made of thongs of twisted cow-hide covered with sheep-skin. With a rope of this description, two men climb to the top of a cliff; there they fasten themselves to either end of the cord; then one lets himself down over the face of the cliff, and the other clings to the rugged points above. The first man fills a sack with the eggs, and suspends by their claws as many goslings as he can hang to various parts of his person. When he has made his 266 collection, his companion hoists him up by main force, twisting the cord round his own body after the manner of a windlass.
This aërial and dangerous sport is very productive. A cow-hide rope forms a large portion of the dowry of a St. Kilda girl, and very often it is the sole dependence of a household. The hardy sportsmen have so much coolness and nerve, that accidents very rarely happen.
The Bean Goose (Anas segetum) of most authors differs from the preceding in being somewhat smaller, and having the bill more slender, although not much shorter; the hind part of the back is also dark brown. In its habits it closely resembles the Wild Goose, for which it has probably been frequently mistaken. Vast flocks of this species frequent the northern waters, such as Montrose Bay, the mouth of the Findhorn, and especially the inland waters of Ross and Sutherland—thirty or forty pairs having their nests annually on Lake Laighal.
The Domestic or Common Goose (Anser sylvestris) has been made the source of great utility and profit. It appears to be the civilised offspring of the Wild Goose, to which it bears the same proportions as other tame animals bear to their prototypes. Mr. Yarrell was of opinion that the White-fronted Goose (Anser albifrons) has concurred, with the Anser ferus, in producing our domestic race.
In our poultry-yards the Domestic Goose begins, in the month of March, to lay from eight to twelve eggs. When they remain on the nest longer than usual, they are about to "sit." Incubation lasts for a month. No birds are more easily reared than goslings; they issue from the shell full of life, and covered with a delicate down. It is, however, necessary to keep them shut up for the first few days; if the weather permits, they may soon be released. Their first food is a paste formed of barley roughly ground, mixed with bran, moistened, and boiled in milk, with the addition of a few chopped-up lettuce leaves. When at large, it is necessary to keep them carefully from hemlock and other poisonous plants.
Our ancestors, the Celts, the Gauls, and the Franks, reared a large number of these birds, and carried on a considerable trade in them, especially with Italy. Pliny, in his "Natural History," 267 relates that he has seen immense droves of Geese, which were making their way towards Rome from different districts of Gaul, but especially from the country of the Morini (now forming the departments of the Nord and Pas-de-Calais). The conductors of these feathered flocks were in the habit of placing the tired ones in front, so that, being pushed forward by the whole column behind them, they were forced to move on in spite of themselves. In the present day, numerous flocks of Geese are driven in the same manner into Spain from the French departments of Lot, Dordogne, Lot-et-Garonne, Gers, Tarn, &c.
The Goose, in its coarse and somewhat democratic condition, was good enough food for the Romans of the republic; but at a later period, when the people became more refined in their tastes, they invented a barbarous method of fattening it. By depriving them of water, movement, and light, an extraordinary development of the liver was produced, which gave them a particularly savoury flavour. This invention—the triumph of modern gastronomy—dates as far back as the days of Augustus and Varro; indeed, two persons of consular dignity disputed the honour of being its originator.
In order to fatten Geese in this way, an abundant supply of food is administered, at the same time depriving them of light and exercise. This food consists of balls made up of maize and wheat, with which the poor creatures are crammed three times a day. In some countries they force whole grains of maize down their throats. At the end of about four or five weeks the fattening process is perfect. This is at all events considered to be the case when the wretched Palmipede exhibits signs of suffocation. This is certainly a cruel method of feeding; nevertheless, it is only by this plan that the delicious fat and plump livers so much appreciated by epicures can be obtained. The liver undergoes an alteration which in the end must prove fatal to the bird; in fact, it assumes enormous development; and the epicures, who hold it in such high favour, regard as a dainty this diseased liver!
The introduction of the Turkey has led to the culture of the Goose being more neglected in Europe; nevertheless, the latter bird is a source of prosperity at the present day in many parts of France, and in many a rural district in England. In 268 ancient times there was no entertainment or family festival without the traditional Goose smoking on the board. In England the Goose is still considered a festival bird. A custom intimately associated with their national history still dictates that every true Englishman should partake of Goose on Michaelmas Day.
The flesh, and especially the fat of the Goose, keeps perfectly when salted down. In parts of the world, in this state it is much employed for culinary purposes. The enormous succulent livers which are found in these precious birds after their forcible fattening are used to make the delicious Strasbourg pies. Those of Nérac, as well as those of Toulouse, are made more of Ducks' livers, for the latter birds can be fattened in very nearly the same way as the Goose.
The down and feathers of Geese are objects of considerable trade. Before the invention of steel pens, the only implement that was used for writing was the quill plucked from the wing of the Goose. Great care was necessary in dressing them. This was done by passing the barrel of the quill through hot ashes, or plunging it into boiling water, with other clarifying processes.
From under the neck, the wings, and the breast of the birds, the down is taken. This operation takes place every two months, from March until autumn.
Geese are certainly not so stupid as they are usually said to be. The following facts will perhaps enable us to appreciate the moral qualities which distinguish them:—
In Scotland a Goose became so attached to its master, that it followed him about everywhere, just like a dog. One day this gentleman, after mixing with the crowd which was moving about the town he resided in, went into a barber's shop to get shaved. The faithful bird had followed him, and waited at the door until his master came out, in order to attend him in his subsequent movements, and then accompanied him back to his home. This intelligent creature could recognise its master's voice, although clothed in any disguise.
In Germany a Gander was in the habit of leading an old blind woman to church every Sunday. It guided her by the skirt of her dress, always conducting her to the seat in the church which she usually occupied. Afterwards it returned into the churchyard to 269 browse upon the grass. When the service was over, it waited, just like a faithful dog, to take charge of its mistress. One day, when the minister called upon her and found her from home, he expressed his astonishment that the poor blind woman should venture out alone. "Ah, sir," replied her daughter, "we have no fears about her—the Gander is with her." Our blind people would make their fortune if they could replace their traditional dog by a guide of this novel kind.
The Bernicle, or Tree Geese, are so called from a foolish tradition of the Middle Ages of their being produced from the barnacle shell which attaches itself to ships' bottoms and timber floating in the sea. They differ from the true Geese in having the head smaller, the bill shorter and more conical, the breast-feathers much larger, and in the predominance of black in their plumage, bills, and feet. The plumage is full, very soft, and close. There are several species of Bernicla, which some recent writers have formed into a genus under that somewhat inappropriate name, the best-known species being the White-faced or Bernicle Goose, Anser leucopsis, Temminck, and the Black-faced or Brent Goose, Anser bernicla, of the same author.

In its winter plumage this is a beautiful Goose, much smaller than those just described, but with a full body, long neck, and a small, oblong, and compressed head, with soft glossy plumage well blended on the head, neck, and breast. It occurs in considerable flocks in the Outer Hebrides, where it arrives in October, and remains till April. A large flock of these birds sitting lightly on the water, advancing with elevated necks, presents a very beautiful spectacle. Nor are they less handsome on the wing as they shoot through the air, now arranged in long undulating ranks, at one time extending in the direct line of their flight, at another flying 270 obliquely, or at right angles to it, and again mingling altogether under some unexplained impulse. Their voice, as it proceeds from a large flock at some distance off, is clear and shrill, producing a pleasant harmony.
The Brent Goose, or Black-faced Bernicle, is much smaller than the Anser leucopsis, and easily distinguished from it by the face and head being entirely black. They seem to have visited our shores in great numbers in former years. In the years 1739—40 these birds were so abundant on the French coast that the people rose en masse to destroy them, and so numerous on the Kentish coast that many were taken in a starving condition. Mr. McGillivray met with large flocks of them in Cromarty Bay, Beauley Firth, and Montrose Basin. Mr. Selby observed them as constant visitors on the shallow waters between Holy Island and the mainland, and other parts of the coast.
The Swan, which belongs to the family of Lamellirostral Palmipedes, has been an object of admiration in all ages for its noble and elegant proportions, the graceful curvature of its neck, its small and shapely oval head, its beak so prominent at the base, the gracefully-swelling rotundity of its body, its plumage 271 so abundant in down, and its colour of purest white of the species with which we are most familiar, and is the finest and largest of all our aquatic birds. On the water it is a picture of elegant ease; it swims apparently without effort, and with great rapidity; on the wing it rises to a great height, but on shore its walk is slow and cumbersome. It is found in Europe, Asia, and America; and in Australia the Black Swan, for ages the rara avis of the poets, is very abundant. In the wild state it lives on the lakes, rivers, and sea-coasts of both hemispheres, feeding on such seeds, leaves, roots, water-insects, frogs, and worms as come in its way. In its domestic state it is the charm and ornament of our lakes and rivers; but, except in some few instances, it is only kept for show, being jealous and cruel in disposition, and incapable of being tamed.
The ancients thought the voice of the Swan musical and harmonious, and its gracefully-rounded form and stately neck inspired many poets, who have described it as the bird of gods and goddesses. 272 The poetical imagination of the Greeks, in short, associated their most agreeable ideas with its name. It was one of their pleasing fictions that in dying and breathing out its last sigh, the Swan celebrated its death by a melodious song; or, as Eloy Johanneau has it—
Buffon himself has drawn the portraiture of this bird in words more poetical than true:—"The Swan," he says, "reigns over the water by every claim which can constitute an empire of peace, grandeur, majesty, and kindness.... He lives more in the character of a friend than a monarch amid the numerous tribes of aquatic birds, all of which seem willingly to place themselves under his rule."
The great naturalist certainly allowed himself to be led away by his enthusiasm, and perhaps by his classic recollections; for the Swan, although elegant and majestic in form, and graceful in its movements on the water, is clumsy and awkward when on land; it is, besides, spiteful and quarrelsome. It attacks every animal, and even man. The Swans in the gardens of the Luxembourg at Paris had taken an aversion to all the keepers, and whenever they saw one, they all came out of the water in order to pick a quarrel with him.
The principal strength of the Swan does not lie in its beak, but in its wings—a most effective offensive weapon, of which it takes every advantage. In spite of its bad qualities, however, the Swan is the most ornamental of all our aquatic birds. Its beak is flesh colour, edged with black, and its plumage white as snow.
Its song, or rather its cry, is indeed far from being harmonious. It is a dull and harsh sibilation, not at all agreeable to listen to. Some of the poets, however, have not believed the fable which attributes to these birds a sonorous and melodious voice. Virgil perfectly well knew how hoarse the note of the Swan really was—
Lucretius also says—
273

This is, in all probability, the Swan so celebrated among the ancients. It is found in the northern regions of Europe and Asia; residing in summer within the Arctic circle, and migrating southwards and visiting Holland, France, and the British Islands in winter, although occasionally breeding in the north of Scotland. Southward, it extends to Barbary and Egypt; eastward, it wanders as far as Japan. The note of the Wild Swan is a sort of whoop, uttered several times in succession—a hoarse, hard, and rather discordant cry—and this has given it the name we have adopted; for it is difficult to imagine the grounds on which the Prince of Canino gave it the name of Cygnus musicus.
The peculiar organic distinction of the Swan is the great length of the neck, consisting of twenty-three vertebræ, and the cavity in the sternum for the reception of the trachea, which is admirably described by Mr. Yarrell as descending the passage between the two branches of the forked bone called the merrythought to a level with the keel of the breast-bone, which is double, and receives the tube of the trachea between its two sides, which here turns upon itself after traversing the whole length of the keel, and passes upwards and forwards, and again backwards, till it ends in the vertical bone where the two bronchial tubes go off, one to each lobe of the lungs. This is the apparatus through which the cry is produced, which is variously described as a whistle, a whoop, or a song, according to the fancy of the writer. They fly at a great height when on a migratory journey, and in a wedge-like figure, uttering this note as they proceed, and when heard at a distance it is not unmusical. Mr. McGillivray listened to a flock of Wild Swans coming in from the Atlantic after a gale: their 274 clear, loud, and trumpet-like cries delighted him as they sped their way in lengthened files; but they were too far off for him to decide whether or not they were of this species.
From six to eight eggs, of a greenish white, the female lays, and the incubation lasts about six weeks. The cygnets are at first covered with a grey down, and do not put on their adult plumage until the third year. Swans care but little for concealing their broods, as they feel confident of their power to protect them against every enemy. They will fight even with the Eagle itself, harassing it with beak and wings, until the marauder is glad to make a more or less honourable retreat.
In the protection of their young they display extraordinary courage. On one occasion a female Swan was sitting on the bank of a river, when she perceived a fox swimming towards her from the opposite bank. Thinking that she would be better able to defend herself in her natural element, she took to the water and went to meet the enemy which was threatening her brood. She soon reached him, and, springing upon him with much fury, gave him such a violent blow with her wing that the fox was disabled, and consequently drowned.
The male Swan is equally with the female attentive to the young brood, and watches them with a rare devotion. He carries them about on his back, takes them under his wings to warm them, and never abandons them while they are still young. It is a beautiful sight to see him gliding over the water at the head of his young flock, looking far ahead with an inquisitive eye, and prepared to sweep away any opposing obstacle; whilst the mother keeps some distance behind, ready to protect the rear. How much, too, are they to be admired as they sail majestically over the surface of some solitary lake! If you hide yourself behind the thick reeds so that they have no suspicion of your presence, you may see these noble birds bending their necks into the most graceful curves, plunging their heads into the water, catching it up in their bills, and scattering it behind them, the drops falling round their bodies in glittering rain; or when, beating the water with powerful wing, stirring up a foamy wave, you may behold them all on a sudden, they will briskly spring up and glide majestically over the surface of the water, cleaving it 275 before them with their graceful bodies as the ploughman opens a furrow in the ground with his ploughshare.
Sometimes, however, these elegant birds engage in terrible combats with one another, which often lead to the death of one of the contestants. The Domestic Swan, a more civilised and well-informed bird, does not push matters quite so far; but Wild Swans, which live in the regions of the North—in the lakes of Iceland and Lapland—hold sanguinary tournaments in honour of their fair ones. A combat between two Swans is a duel to the death, in which both adversaries display not only unequalled strength and fury, but also considerable skill and perseverance. The strife will sometimes last several days, and does not terminate until one of the foes has succeeded in twisting his neck round that of his enemy, and has been able to hold him down under water long enough to drown him.
But let us turn from this warlike spectacle and admire the Swan at the moment when, impelled by the stimulus of love, it displays all the graces with which nature has endowed it. Their long and supple necks entwine with one another like garlands of snow, their plumage swells up with gentle undulations, and they display all the splendour of their beauty.
The Swan is certainly conscious of its good looks and grace, for it is constantly busying itself either in cleansing or polishing its feathers. Besides, it unites the useful and the ornamental, by extirpating the weeds which stagnate at the bottom, and by thus transforming what would be a nasty pool into a clear sheet of water.
These birds do not afford good sport with the gun, being unapproachable. In Iceland and Kamtschatka, Swan-hunting takes place during the season of moulting, because the birds are then unable to fly. Dogs trained to this sport chase and run them down; the birds, being soon worn out with fatigue, are easily killed with sticks.
The Russians have another mode of killing Swans. When the snows melt, they allure them by means of stuffed Geese and Ducks. The Swans dart furiously on these decoys. The sportsmen, hidden in a hut constructed of branches of trees and heaps of snow, at short range easily shoot them. 276
The flesh of the Swan is very indifferent in flavour. Our fore-fathers ate it, but merely from ostentation, for it was only served up on the tables of the greatest nobles. At the present day, the city of Norwich has a preserve for Swans, which are only eaten at the municipal feasts, or sent as presents to distinguished individuals. In these cases, the birds being young and tenderly fed, are by no means, if properly cooked, a dish to be despised. The inhabitants of the frozen regions of the extreme north, even with their imperfect system of cuisine, do not entirely disdain it; but the cause for this is apparently something analogous to the philosophical saying, "as there are no thrushes, we eat blackbirds."
The river Thames is remarkable for the number of Swans which live on it. The greater quantity of them belong to the Queen; the others chiefly to the Vintners' and Dyers' Companies of the City of London; but we never heard that these feast their guests on the noble birds. Deputations from the companies make an annual visit to their preserves, called Swan-hopping, or capering—that is, catching the cygnets, and marking them in the presence of the royal swanherd with the distinguishing brand of the society to whom the parent bird belonged.
Two species of Swans were recognised by Linnæus; but later 277 naturalists, and notably the Prince of Canino, record four species known in Europe—namely, Cygnus olor, C. immutabilis, C. musicus, and C. Bewickii—besides the American species, namely, C. americanus and C. buccinator. There is another species, peculiar to Australia, which is entirely black: efforts have been made successfully to naturalise it in Europe.
Synonyms.—Anas Plutonia: Shaw. Chenopis: Wagler.
We here give a representation (Fig. 100) of the Black Swan of Australia. This bird, which has now become so common in our ornamental waters, in some respects resembles the White species; it is all black, except a few of the secondary feathers, which are white. In a state of nature, the Black Swans are generally seen in flocks of eight or nine floating on lakes. When disturbed, they fly in single file, and are so shy that it is very difficult to get within gunshot when in captivity. Their note is less harsh than that of the Whooping Swan.

Latin Synonym.—Tachypetes: Vieillot.
The Frigate Bird is principally characterised by a strong, robust, trenchant bill, longer than the head, with mandibles hooked at the point; nostrils linear; orbits naked; throat dilatable; the front of the neck bare of feathers; wings very long and narrow, first two feathers longest; tail lengthy and forked; feet short; toes united by a membrane deeply notched.
The Frigate Bird spreads its wings to the extent of three yards; its power of flight is, therefore, very great. It inhabits the tropical seas of both the Old and New World, and navigators assure us that they have met with it two or three hundred leagues from any shore. When a hurricane arises they mount up far above the storm, and remain in these empyrean regions until it is again fine weather. In consequence of their immense expansion of wing, they can sustain themselves in the air for days together without taking or requiring rest. 278
Their sight is so piercing that, at a distance far beyond that which would render them invisible to us, they can perceive the flights of Exocœti, or Flying Fish. From their elevated situation, they dart down upon their winged prey, which has relinquished its native element; and, keeping their neck and feet in a horizontal position, and thus grazing the waves, they grasp their victim, which little expected to meet with an enemy in the element which it sought for safety. It is no unusual thing for it to rob the Gannet of the fish which it has just caught: the unfortunate bird thus acts as purveyor to this sea-robber.
The Frigate Bird is of such a combative temperament, and has such an unbounded confidence in its strength, that it is not afraid to defy even man. It has been known to dash at a sailor, and to snatch at the fish which he held in his hand. M. de Kerhoënt, a French navigator, relates that, during a residence at the Island of Ascension, a perfect cloud of Frigate Birds surrounded his crew. They hovered about, a few feet above the coppers of the open-air kitchen, in order to carry off the meat, without being intimidated in the least by the presence of his followers. Some of them approached so near that M. de Kerhoënt knocked down one of the impudent intruders with a blow of his stick.
When these birds have thoroughly feasted on fish, or any other of the marine creatures which constitute their food, they take flight landwards, and proceed to perch upon a tree, in order to digest their food in peace.
They assemble in large flocks on the islands where they are accustomed to breed. In the month of May they begin to repair their old, or construct new nests. They pluck off small dry branches with their beaks, and with these pieces of stick crossed and recrossed a foundation is formed. These nests are suspended from trees which hang over the water, or are placed on rocks in desert islands, overhanging the sea; in them they lay two or three eggs, said to be of a carnation colour dotted with crimson.
These birds are common in the Brazils, in the Island of Ascension, at Timor, the Ladrone Islands, and the Moluccas: in fact, they are to be found in most tropical countries. Navigators, struck with the lightness of their flight and their slender shape, have given them the name they bear, thus comparing them with the fleetest 279 and most elegant of men-of-war. Sir Hans Sloane, who saw numbers of them at Jamaica, describes them under the name of Man-of-War Birds. "They fly," he says, "like Kites, look black, are very large-winged in proportion to their size, and they fight with Sea Gulls for their prey." They are eminently raptorial. Ray speaks of their eagle eye, vulturine claws, and cat-like gliding movements, their immense extent of wing, and their dashing swoop.
The Palmipede we are about to notice received from Linnæus the mythological name of Phaeton, in allusion to the son of Apollo and Clymene, who is said to have made an audacious attempt to drive the chariot of the Sun.
The Pelicanidæ, which Mr. Gray makes his sixth and last family of Palmipedes, includes Cuvier's Totipalmes, or birds having the hind-toe united to the others by a single membrane. This extensive family comprehends the Tropic Birds (Phaeton), the Anhingas (Plotus), the Boobies (Sula), the Cormorants (Phalacrocorax), and the Pelicans (Pelicanus).
The group comprehends those birds which have the base of the bill denuded of feathers, the nostrils mere slots, in which the opening is scarcely perceptible; the skin of the throat more or less capable of distension; the tongue small. Some of the group are large and heavy birds, but they are all gifted with powerful wings; they are, at the same time, good swimmers.
Synonyms.—Lepturus: Mœhr. Tropicoliphus: Leach. Tropic Bird: Sloane, Catesby, and others.
These birds are well known to navigators as the harbingers which foretell the approach to the Tropics. They are distinguished by two long, slender tail-feathers, whence their French name of Paille-en-Queue. They are gifted with great length of wing, which, with their feeble feet, proclaims them formed especially for flight. They are accordingly swift and untiring on the wing, heedlessly going far out to sea; forming, as Lesson remarks, a 280 well-defined and purely geographical group, their homes being in rocky islands, to which they usually return every night. Nevertheless, he frequently met with them in sea-tracks far from any land, possibly they having been swept, by the sudden squalls and hurricanes so frequent in equatorial seas, beyond their natural limits.
The Common Tropic Bird, Phaeton æthereus, seems to confine itself, according to this writer, to the Atlantic Ocean, stopping on the confines of the Indian Ocean; the other species, Phaeton Phœnicurus, seeming to belong further eastward, both meeting in nearly equal numbers at the Mauritius and other islands of the same group. Their flight is described as calm, quiet, and composed of frequent strokes of the wing, interrupted by sudden falls. The bird is about the size of a Partridge, with red bill and markings under the lower mandible; in general appearance it resembles the Gulls, but has longer and more powerful wings; the legs and feet are vermilion red, the latter webbed; the tail has two long, narrow feathers. One of their breeding-places is the Bermudas, where the high rocks which surround the island are a protection from the attacks of the fowler. P. Phœnicurus is a larger bird, being thirteen inches from the bill to the root of the tail; the long tail-feathers being red of the deepest hue. 281
The appearance of this bird announces, as we have said, that the navigators have entered the torrid zone, as this bird rarely goes beyond the limits of this region. It sometimes, however, pushes out to sea to a distance of a hundred leagues. When they are fatigued, aided by their large webbed feet, they rest upon the waves. Like many other ocean birds, their peculiar organisation prevents them settling from choice on the ground. They are, therefore, compelled to skim continually over the water, in which they feed upon the fish and mollusks, which form their principal food. When they are on the shore, the immense spread of their wings induces them to choose some elevated spot for a perch, such as the top of a tree or the summit of a rock. Worn out by fatigue, if they settle on the water, they are forced to wait until they are lifted up on the crest of a wave before they can again take flight. Their mode of flying is rather curious, for they communicate to their wings a kind of quivering motion, as if overcome by exhaustion.
These birds seek some remote and solitary islet for the purpose of breeding. They build their nests in holes in lofty trees, or in the clefts of rocks, but always in some position difficult of access. They lay two or three eggs. The young ones, when just hatched, owing to their dazzling-coloured down, bear a considerable resemblance to powder-puffs.
There are three species of the Phaeton—the Red-tailed Phaeton (Phaeton Phœnicurus), with white plumage, shaded with a light rose-coloured tint, having the two long feathers of the tail of a red hue. It inhabits the seas of India and Africa, Madagascar, the Isle of France, and the Pacific Ocean. The White-tailed Phaeton (Phaeton æthereus), with white plumage, with the two long feathers in the tail white. It is a native of the Atlantic Ocean. The Yellow-beaked Phaeton (Phaeton flavirostris) is distinguished by the colour of its beak. It is a native of the islands of Bourbon and Mauritius.

The Darter (Fig. 102) has a straight and pointed bill, with 282 indentations at the point, turned in a backward direction. Its head is slender and cylindrical, and forms the termination of a slim and excessively long neck, which gives it much the resemblance of a serpent grafted on a bird. In all its movements this neck is the counterpart of the reptile, and imitates its undulations; therefore, in the United States it has received the name of the "Serpent-Bird." They are untiring swimmers and excellent divers. When any danger threatens them, they dive completely under water, and do not reappear until they have found some tufts of reeds in which to hide, even should the distance be as much as one thousand feet from the spot where it disappeared. These birds are of a wild and suspicious nature, confining themselves to solitary places. They perch upon trees which grow by the sides of a pool or river, in order to dart upon any unfortunate fish which comes within their reach, which they seize with extraordinary address, swallowing it whole if not too large. If 283 they cannot manage this, they carry it to a rock, where they dismember it with their beak and claws.
The Anhinga builds its nest on the topmost branches of trees, constructing it of dried twigs and reeds, and lining it inside with a thick layer of down.
Only two species of the Anhinga are known: the Anhinga (Plotus) Levaillantii, a native of Africa, the plumage of which is black from the breast to the tail; and the Black-bellied Darter (Plotus melanogaster), an American species.
Levaillant, in his usual lively manner, relates that he was induced to visit a rich proprietor in the Canton of the Twenty-four Rivers by a tempting description he received of two extraordinary birds which haunted the vicinity. They frequented a particular tree, and baffled him more than once by their skill; but at length he got within shot, and killed both of them right and left. He describes them as diving for fish. When they caught a small one it was swallowed; when a large one, it was carried to a rock or the trunk of a tree, when the bird, fixing it beneath its feet, picked it to pieces with its bill. Though the water is its favourite element, it is on trees and rocks, he tells us, that it establishes its nest and brings up its young, taking care to place the nest so that the young may be precipitated into the water as soon as they are able to swim, or when the safety of the family requires it.
Synonyms.—Solan Goose, Booby; Fou de Bassan of the French.
The Gannet is a massively-made bird, not of graceful shape; it is larger than a Duck, and has white plumage.
They have obtained the name of "Booby" from the supposed stupidity which, rightly or wrongly, is attributed to them; for if a man finds one of these birds standing in his way, the creature offers no resistance, but will allow itself to be killed rather than abandon its position. The Frigate Bird, with audacious rapacity, when it observes the Gannet catch a fish, swoops down upon it and compels it to disgorge its prey. Their somewhat imperfect organisation explains this habit of non-resistance. The shortness of their legs and the excessive length of their wings prevent them 284 escaping from their enemies when on shore, nor have they sufficient power of flight to avoid them in the air. But when they are aloft they soar wonderfully, with their necks stretched out, the tail expanded, and the wings almost motionless. Although they are strong on the wing, they do not venture very far from shore, consequently they are never met with more than twenty leagues at sea. Their appearance, therefore, is considered by the mariner as an indication of the proximity of land. In their flight they frequently skim over the surface of the sea, catching such fish as swim near the top. The skin of their throat is so readily distended that they can swallow their prey whole. The Gannet is also an excellent diver, for it is able to remain more than a minute under water when in pursuit of a favourite prey.
These birds are found in every part of the globe, giving the preference, however, to tropical countries; still they are plentiful in the Hebrides, in Norway, Scotland, and are even found as far 285 north as Kamtschatka and the Gulf of Bothnia, according to Acerbi. But when residents of high latitudes, they migrate southward on the approach of cold weather. In the winter season they frequent the coast of Cornwall, and are found, in fact, in every part of the British and Irish Channel, generally keeping out at sea. They are constant attendants on the large quantities of herrings and pilchards that frequent our coast late in autumn.
This bird takes its prey by darting down on it with great velocity; yet it does not appear to dive—swimming, it floats upon the water with the buoyancy of a gull, not submerged, as is the case with the Shag and Cormorant.
Three species of them are known: the Solan Goose, or Gannet (Sula Bassan), which is very common on the Bass Rock, a small islet in the Firth of Forth, and on the northern islands—this is the only European species; the Common Gannet (Sula dactylatra), vulgarly called "Mouche de Velours"—this is smaller than the preceding, and is found in the Island of Ascension; the Brown Gannet (Sula fusca), which inhabits South America.
English Synonyms.—Cormorant: Willoughby, Albin, Montagu. Great Cormorant: Bewick, Yarrell. Crested Cormorant: Bewick. Cormorant: Shaw, Latham, Lewin, Walcot, Pultney. Provincial: Great Black Cormorant, Cole Goose, Skart, Green Cormorant, Norie.
Latin Synonyms.—Carbo carboranus: Meyer. Pelicanus carbo: Linn., Latham, Gwellin. Corvus aquaticus: Ray, Willoughby. Phalacrocorax: Brisson, Temminck, Cuvier, Bonaparte. Halicus: Illiger. Hydrocorax: Vieillot.
The Cormorant is distinguished by a bill straight and compressed, the upper mandible curving downwards, and forming a hook at the termination; lower mandible inserted in a small membrane extending under the throat; feet strong, short; toes three before and one behind, united by a membrane; nail of the middle toe serrated; wings moderate, the first quill longer than the second, the whole being blackish; the upper part of the back and wings ashy brown, or bronzed in the middle, bordered by a large band of glossy greenish black. 286
The Common Cormorant (Fig. 104) has a massive and rather awkward body, feet short and drawn back to the abdomen, the head flattened and small, the guttural pouch very small. Their bulk varies, according to the species, from the size of a Goose to that of a Teal. On the south coast of England they are large birds, Pennant having weighed one which exceeded seven pounds, and measured three feet four inches. Their blackish plumage has given the idea of some resemblance existing between them and the Crow; hence their name, "Cormorant," from Corvus vorans, which signifies a voracious Crow.
These birds have a wide geographical distribution, being found in all parts of the globe, and always on the sea-coast or at the mouths of rivers. They are excellent swimmers and clever divers, pursuing with extraordinary rapidity the fish on which they feed.
The Cormorant swallows its prey head first; and if it happens to catch it by the wrong end, it will throw it up in the air, and seize it again in its bill as it descends in the proper position. When it has caught an eel, a good half-hour sometimes elapses before it can succeed in swallowing it. It may be seen making the most violent efforts to swallow its prey; and just at the moment when one would think that the slippery morsel was successfully absorbed, the fish suddenly reappears again from the depths of 287 its living sepulchre, still straggling to escape; the Cormorant re-swallows it again; the eel still resists, and increases its efforts to escape; worn out at last by its prolonged and useless efforts, the victim is finally compelled to resign itself to its fate.
The appetite of the Cormorant is insatiable. The havoc which it commits in rivers is very great, for one day's consumption frequently amounts to six or eight pounds of fish: these it pursues principally under water, for it is an expert diver, and most successful in its search for its prey. In consequence of the skill displayed by the Cormorant in fishing, and the ease with which it is tamed, it is reared in a semi-domestic state in certain parts of Eastern Asia. The Chinese and Japanese are the nations who best know how to utilise the habits of these birds. When thus used a ring is placed round their necks to prevent them swallowing their prey, before turning them loose in waters which abound with the finny tribes. The Cormorants, trained to obey their master's voice, and balked in their attempts to swallow by the ring round the neck, bring to their owner all fish they capture. Sir George Stanton, in his embassy to China, having reached Len-tze, famed for its breed of these birds, found them to be a species somewhat resembling the Common Cormorant, described by Dr. Shaw as a Brown Cormorant with white throat, the body whitish beneath, spotted with brown; the tail rounded; irides blue, and bill yellow; which he named Phalacrocorax sinensis. "On a large lake," Sir George says, "close to this part of the canal, and to the eastward of it, are thousands of small boats and rafts built entirely for this species of fishery. On each boat or raft are ten or a dozen birds, which, at a signal from the owner, plunge into the water; and it is astonishing to see the enormous size of fish with which they return. They appeared to be so well trained that it did not require either ring or cord round their necks to prevent them swallowing their prey, except when they received the permission of their master to do so, as an encouragement for their labours."
The dexterity with which the Cormorant seizes its prey is such that if a dead fish is thrown into the water from a distance, the bird will dive immediately, pursuing its course in a direct line to the 288 spot, never failing to secure it, even before it reaches to the bottom. On shore the Cormorant is a dull, heavy bird, and it is only in the water, and especially while fishing, that it appears to advantage. It floats so low in the water, and swims and dives so quickly, that it seldom fails to capture its prey. Now on the surface, next moment below, onward it plunges as if making an attack; then rising suddenly in some unexpected spot after a lengthened dive, it is certain to have the unfortunate fish in its bill.
Another peculiarity which belongs to this species is common with many other aquatic birds—that of violently beating the water with its wings without moving from the spot, followed by a vigorous shaking of the whole body, with the feathers ruffled, and, at the same time, covering itself with water. After repeating this several times with small intervals of rest, it will retire to an elevated place on shore, where it will remain with outspread wings until dry.
The flight of these birds is rapid and lasting; but they are as heavy and awkward when on land as they are nimble and active in the water. Their nature being unsuspicious and trustful, they can be easily approached, particularly when resting after their fishing exertions.
The Cormorant is widely diffused both in the Old and New World. It is a migratory bird, but is seen on our coast at all seasons. It breeds among rocks on the coast, selecting crags and inaccessible places, which sometimes are covered with their nests: these are composed of sticks and sea-weed, in which the female deposits her eggs, generally three in number, and which are of a whitish colour, weighing about two ounces.
In Egypt four species of Cormorants are known. The Great Cormorant (Carbo cormoranus) is the size of a Goose; this species is often domesticated, and is frequently met with in France. 289

This species is in weight about four pounds; the bill is dusky, and about four inches in length; a bare yellow skin is situated along the sides of the mouth and chin, the latter speckled with black. The whole bird appears black at a little distance, but on nearer examination, the head, neck, breast, and rump are of a glossy green. The feathers of the upper part of the back, scapulars, and wing coverts are pointed, and beautifully glossed with purple, violet, and green, each feather being edged with a velvety black; the under part of the body is less glossed with green; the legs are dusky black; middle claw serrated.
The female weighs over three pounds; the upper part of her body is dark, not so densely glossed as in the male; but the margin of the feathers of the scapulars and wing coverts is black, the under part dusky, with a mixture of grey.
Such is Colonel Montagu's description of a pair shot from the nest, but they vary in plumage and colour. In habit the Shag is strictly a salt-water bird, never visiting fresh water, breeding on our rocky coasts, where it builds a nest of stick and sea-weed. They resort to the maritime caves of the Hebrides in such vast numbers that they literally cover the sea to a considerable extent when on their passage from the caves of Liuir and Toehead to their fishing-grounds in the sound. Mr. McGillivray has counted a hundred and five in one flock. This picture Mr. McGillivray makes the text for one of his most delightful descriptions:—
"There is a large cave," he says, "on the west coast of Harris, celebrated for the number of Shags which reside on it, and so lofty that a boat can enter it to a considerable distance with lowering the 290 masts. When we appear off the mouth of the cave a considerable number appear conspicuously perched on the little shelving rocks and projections, their dusky figures strongly relieved by the whitened surface of the rocks. Some of them fly overhead as we approach, but more drop into the water like a stone. On looking down we see them rapidly winding their way under the boat, swimming with outspread wings, and not at all in the manner represented by some writers, who say that it propels itself entirely under water by the feet and tail. Glancing aloft, we see many Black Guillemots in the clefts; and above them is the eyrie of the White-tailed Eagle. But our business is with the Shags, which are now seen writhing their long necks as they gaze upon us. Presently a shot is fired, and another; the dead birds drop on the water, the living plunge headlong into it, many advance on the wing, but, being frightened by the upraised oars, dart into the water.
"Advancing a little, we find that many still remain on the rocks; of these we shoot some more. Presently some of those which had escaped return, and perch; and we continue shooting until we have obtained as many as we desire. After all the uproar we have created, several still remain standing near their nests, loath to quit them. Although most of the nests are out of reach, some are accessible. We find them generally bulky, sometimes very scanty, formed of fuci, twigs, heath, and grass rudely put together, made flat, or with a shallow cavity, containing two, frequently three, sometimes four eggs, never more."
This bird has black plumage, as we have seen, is smaller than the one preceding, and inhabits the Arctic and Antarctic regions. A bird nearly resembling this (Phalacrocorax Desmarestii) is described by Temminck and figured by Gould, a species which has been observed in Corsica, and is of a blackish green. Montagu satisfied himself that the Crested Cormorant was only a seasonal variety of the Common Cormorant; and probably others of the species described, if carefully examined, would prove to be the same. McGillivray is of opinion, however, if Mr. Gould's figure is correct, the species must be distinct. 291
A comprehensive group of aquatic birds presenting a uniformity of structure quite apparent in the skeleton, and especially in the digestive organs, of which the Pelican is the type. They are mostly birds of large size, but of slender, elongated body, long neck, and head generally of moderate size. The bill is long, sometimes slender, at other times rather stout and straight; the upper mandible with the ridge separated by grooves, and terminated in a narrow, decurved, and pointed nail, or claw; the lower mandible elastic and extensible. The plumage is soft and blending, on the back and wings compact and imbricated; wings long, tail of moderate length and narrow.
The habits of the group vary considerably. Cormorants pursue their prey much in the same manner as Mergansers and Loons; the Anhingas are strictly territorial; the Pelicans combine the habits of both. The Gannets fly about in quest of food, plunging upon it from on high. The Frigate Birds range over the seas with unrivalled power of flight, and the Tropic Birds resemble in progression the Terns. The family comprises—
The Pelican (Fig. 105) has the bill long, straight, rather broad, and very much depressed; upper mandible flattened, terminating in a hooked tip much bent and compressed; lower mandible formed of two bony branches united at the point, from which a membranous naked skin is suspended, forming a purse, which can be distended into a voluminous bag. The Pelicans are large, heavy aquatic birds, with great extent of wing, and are excellent swimmers; their haunts are estuaries, the sea-coast, and the banks of rivers, lakes, and marshes. In its habitat, whenever a fish betrays its presence by leaping or flashing its glittering scales in the sun, the Pelican will be seen sailing towards it.
This bird has an appetite so insatiable, and a stomach so capacious, 292 that, in one day's fishing, it devours as much fish as would satisfy six men. The Egyptians have nicknamed it the "River Camel," because it can imbibe at once more than twenty pints of water. Certainly it only makes two meals a day; but, oh! what meals they are!
Pelicans often travel in considerable flocks, visiting the mouths of rivers or favourite retreats on the sea-coast. When they have made choice of a suitable place, they arrange themselves in a wide circle, and begin to beat the water with extended wing, so as to drive the fish before them, gradually diminishing the circle as they approach the shore or some inlet on the coast. In this manner they get all the fish together into a small space, when the common feast begins. After gorging themselves they retire to the shore, where the processes of digestion follow. Some rest with the neck over the back; others busily dress and smooth their plumage, waiting patiently until returning appetite invites all to fresh exertions. When thus quiescent, occasionally one of these birds empties his well-lined pouch, and spreads in front of him all the fish that it contains, in order to feed upon them at leisure. 293
This guttural pouch, which plays so important a part in the Pelican's life, is composed of two skins, the outer one being a prolongation of the skin of the neck; the inner one is contiguous to the coating of the œsophagus. The tongue is small: a delicate gizzard forms one large sac with the other stomachs.
In spite of its great size, the Pelican flies easily and to considerable distances. It is no diver, but will occasionally dash down on fish from a considerable height, and with such velocity that it becomes submerged; but its buoyancy instantly brings it to the surface again. It perches on trees, but seems to prefer rocks. When it builds a nest, it is generally formed of coarse reedy grass, lined with softer material, placed in the cleft of dry rocks near the water. Here the female deposits two, three, four, sometimes five white eggs, but most frequently only two. They are occasionally satisfied with placing their eggs in an indentation in the ground which they have roughly lined with blades of grass.
After an incubation lasting from forty to forty-five days, the young ones, covered with a greyish down, are hatched. The female feeds them: she presses the hooked red point of the mandible against her breast, which causes her to disgorge the fish it contains into the bills of the young ones, the male performing the same operation on himself for the benefit of his partner. This is probably the fact that has given origin to the absurd fable that the female Pelican is in the habit of piercing her breast in order to nourish her young with her maternal blood. The young birds are easily tamed. It is even asserted that they are susceptible of education, and that, like the young Cormorants, they can be taught to fish for their masters.
The Pelican is more common in tropical regions than in temperate climates. They are very numerous in Africa, Siam, Madagascar, the Sunda Isles, the Philippines, Manilla, and in the Western Hemisphere they abound from the Antilles to the northern temperate part of the South American continent. The true Pelicans are large birds with powerful wings, and are excellent swimmers. The pouch has extraordinary elasticity, and is capable of containing a number of fish either for its own consumption or the nourishment of its young. It haunts the 294 neighbourhood of rivers and lakes and the sea-coast, being rarely seen more than twenty leagues from the land. Levaillant describes one of those wonderful ornithological scenes which only occur in uninhabited regions. At the entrance of Saldanha Bay, on the south-west coast of Africa, after wading through the surf and clambering up the rocks, "all of a sudden there arose from the surface of the Island of Dassen-Eyland an impenetrable cloud, which formed, at the distance of forty feet above our heads, an immense canopy, composed of birds of almost every kind of water-fowl—Cormorants, Sea Gulls, Sea Swallows, Pelicans, and I believe the whole winged tribes of this part of Africa were here assembled. Their voices, harsh and discordant, formed a noise so unmusical that I was every moment compelled to cover my head in order to relieve my ears. The alarm we created was so much the more general, inasmuch as the birds disturbed were chiefly sitting females. They had nests, eggs, and young to defend." In this scene the Pelican, from its peculiar appearance, was of course a prominent object. The best-known species are—1, the White Pelican; 2, the Crested Pelican; 3, the Brown Pelican; and 4, the Spectacled Pelican.
English Synonym.—White Pelican.
Latin Synonyms.—Pelicanus onocrotalus: Linn., Temminck, Selby. P. minor: Ruppell.
French Synonym.—Pélican Blanc: Temminck.
The White Pelican (Pelicanus onocrotalus) is as large as a Swan. Its bill is about fifteen inches in length. Its plumage is white, with a slightly rosy tint, which is brightest in the breeding season; the pinnaries and spurious wings are black; the crest and a few feathers on the neck yellowish.
This species received from the ancients the name of Onocrotalus, because they fancied that they discovered a resemblance in its cry to the braying of an ass. It is very common on the lakes and rivers of Hungary and Southern Russia, as well as on the banks of the Danube. If it is seen in France, it is purely accidental, as it is a rare visitor. A wild rocky shore, where it can look down on 295 the sea, is the favourite haunt of the Pelican; but it is not uncommon for it to perch on trees. The nest is formed of coarse reedy grass, with a lining of finer quality; it is generally made on the ground, and is about eighteen inches in diameter, in which it lays four, sometimes five, white eggs, but more frequently two, slightly oblong, and alike at both ends. Fish forms its principal food, which it captures chiefly in shallow inlets; for it is no diver, although on the wing it dashes upon a fish occasionally from a great height, and that with such velocity that it submerges itself, but its buoyancy brings it immediately to the surface. Occasionally it flies very high, but it generally just poises itself over the water. Notwithstanding its webbed feet, it often perches on trees—a habit which Sonnerat describes as peculiar to the female in the evening, after having fed and protected her young during the day.
Synonyms.—Pelicanus crispus: Bonaparte, Temminck, Bruck. Pelican: English authors. P. onocrotalus (var. Orientalis): Linn, Pallas, Dalmatian. Riesen-pelikan: German authors.
The Crested Pelican, in common with the White Pelican, inhabits the south-east of Europe and Africa, and is also found in Hungary, Dalmatia, Greece, the Crimea, and the Ionian Islands, as well as in Algeria, and, according to some authors, it is frequently met with in China.
It has white plumage, with the exception that the ends of the feathers of the back and wings are black. The feathers of the head and upper part of the neck are twisted up so as to form a tolerably large tuft or crest: hence the name it bears. Its habitat is principally the marshes round the Black Sea, and the isles adjacent to the mouth of the Danube.
Of their habits, travellers in these regions give very interesting descriptions. Count Mükle states that they are plentiful on the lakes of Missolonghi, and in the marshy grounds near Thermopylæ. In situations incredibly difficult of access, especially on floating islands, scarcely over the water-line, they place their nests thickly together, supported among reeds and rushes. The vicinity of these congregated nests is rendered indescribably offensive by the 296 foul fish they have dropped about, and the disagreeable white dung with which all the neighbourhood is covered.
"Time was," says Mr. W. H. Simpson, "and that not so long ago, when Pelicanus crispus lived in hundreds all the year round, from the rocky promontory of Kourtzalari, hard by the mouth of the Acheloüs, on the western extremity of the lagoon, near the island of Ætolico, up the northern arm, and on the east along the great mud flats which mark the limits of the present delta of Phidaris. Nowadays, however, a solitary individual may be seen fishing here and there throughout the vicinity; the remnant have betaken themselves to the islands which divide the Gulf of Procopanisto from that of Ætolico. Here, towards the end of February last, the community constituted a group of seven nests—a sad falling off from the year 1838, when thirty-four nests were grouped upon a neighbouring islet. As we approached the spot in a boat the Pelicans left their nests, and taking to the water, sailed away like a fleet of stately ships, leaving their preconcerted nursery in possession of the invader. The boat grounded in two or three feet of mud, and when the party had floundered through this, the seven nests were found to be empty. A fisherman had plundered them that morning, taking from each nest one egg, which we afterwards recovered. The nests were constructed in a great measure of the old reed palings used by the natives for enclosing fish, mixed with such pieces of the vegetation of the islet as were suitable for the purpose. The seven nests were contiguous, and disposed in the shape of an irregular cross, the navel of the cross, which was the tallest nest, being about thirty inches high, the two next in line being about two feet, and the two forming the arms being a few inches lower, the two extremes at either end being about fourteen inches from the ground.... The eggs are chalky, like others of the Pelicanidæ, very rough in texture, and some of them streaked with blood."—("Ibis," vii. p. 395.)
The Brown Pelican is an American species, smaller than the preceding, and is described at some length by Nuttall. It has the head and the neck variegated with white and ash-colour; all the 297 rest of the plumage of a brownish grey, with whitish marks on the back; the pouch is of an ashy blue, striped with a reddish hue. It is found in the Larger Antilles, on the coasts of Peru, in Bengal, and in South Carolina.
The Spectacled Pelican, which is only found in southern climates, is thus named from the naked skin which surrounds the eye, reminding one of spectacles by its more or less circular form. Its plumage, like that of its congeners, is white. 298
"Notwithstanding the dissimilarity of the bill," says Mr. Vigors (Linn. Trans., vol. xiv.), "the Sterna and Rhynchops most intimately accord in habits and external characters. The Gull-billed Tern of Colonel Montagu conducts us from these genera to the groups which compose the Linnæan genus Larus—now divided into two genera, Lestris and Larus. From this group we are led to the genera Diomedeæ and Haladroma, by the absence of the hind toe, by means of the species Larus tridactylus (Latham), where, though the hind toe is not absolutely different, as might be inferred from its name, there appears but the rudiment of one. The last-mentioned genus, Haladroma, originally belonged to Procellaria, and was separated from it by its tridactyle foot. Even in this character, however, it forms a connection from Larus to the groups that compose the genuine Procellaria, all of which are distinguished by the singular peculiarity of having no true hind toe, but only a nail adhering to the tarsus in its place. We thus arrive at the Petrels, separated into groups of the Procellaria (Anet), Pachyptila (Ilf.), Puffucus (Ray)."
The Grands Voiliers, or Long-winged Birds, are thus named from their powerful and enduring faculty of flight. Mariners meet with them everywhere, and easily recognise them by their long and pointed wings, forked tails, and short legs. In this order the back toe is unconnected with the others, or is wanting, and the membrane which unites the others much notched; their bills 299 are sharp and pointed, and without indentations. They pass their lives at a great distance from land, and do not approach the shore except for breeding purposes. To this sub-order belong the Sea Swallows (Sterna), Scissors-bills or Skimmers (Rynchops), the Sea Gulls (Laridæ), the Labbes (Stercoraria), the Petrels (Procellaria), Albatross (Diomedea).
English Synonyms.—Common Tern: Selby, McGillivray, Morris. Greater Tern: Montagu, Bewick, Pennant. Local names: Sea Swallow, Gull Teaser, Tarney, Tarrock, Kippock, Scraye.
Latin Synonyms.—Sterna hirundo: Pennant, Montagu, Bewick, Flemming, Selby, Jenyns, Gould, Yarrell, Latham. Sterna major: Brisson. Hirundo marina: Ray, Willoughby.
There are six species of Sterna, properly so called, described by British naturalists; and six others, according to McGillivray, nearly resembling them in form, colour, and habit. The true Sterna has the bill straight, slender, compressed, and tapering; it is about the length of the head, with the edge sharp, and the tip elongated and pointed; the upper mandible armate; legs short, slender; anterior toes small; membrane emarginate; wings long and pointed; tail forked. These birds are remarkable for their buoyant, graceful, easy flight, and the soft, loose texture of their plumage. Their prevailing colours are a pale bluish grey or black, and white.
The Tern, or Sea Swallow, as it is commonly called, on account of its long pointed wings and forked tail, appears to be, like the Swallow properly so called, a perfect disregarder of rest. They may be seen soaring in the air at a very great height, and then suddenly darting down upon their prey, which their piercing sight has enabled them to descry in the water. Often, too, they may be noticed skimming over the surface of the waves with astonishing rapidity, and seizing in their flight any fish which is imprudent enough to show itself. Their flight over the sea seems incessant, and it is rarely they are seen swimming. When they need rest, they seek some solitary, isolated rock in the ocean. They congregate in flocks more or less numerous, and they manifest so much attachment for individuals of their own species, that, when one of them is wounded by the sportsman's 300 gun, the others surround it, full of grief and sympathy, nor will they leave it until all hope of saving its life is at an end.
These birds in their flight give utterance to shrill and piercing calls, which, when produced by numbers together, cause a deafening uproar in the sky. These calls are raised with increased power when they are about to undertake some longer flight than usual. But the time, above all others, when their noise is most discordant and shrill is the breeding season. "On going up to one of their breeding-places," says McGillivray, "which may always be discovered from a distance, as some of the birds will be seen hovering over it, one is sure to be met by several of them, which hasten to remonstrate with the intruder by harsh cries and threatened blows. As you draw nearer, more of them leave their nests; and at length they are all on the wing, wheeling and bounding—now high and now low—at times coming quite close, and increasing their cries, which resemble the syllables 'cree-cree-cree-ae.'"
Like the Land Swallows, these sea-birds arrive on our coasts in the spring. They disperse themselves over our lakes and large ponds, where they feed on any animal substances they meet with—either fresh or putrefied—fish, mollusks, or insects. Montagu says they are found in great abundance on the Sussex and Kentish 301 coasts, particularly about Winchelsea, and in the Romney marshes towards Dungeness. Mr. Selby found them breeding in the Solway and in the Firth of Clyde. McGillivray met with them in great numbers in South Uist and Long Island; and his correspondents, Messrs. Bailie and Heddle, noted their annual arrival in the Orkneys in May. "They arrive in straggling flocks in the beginning of May," says McGillivray, "and soon betake themselves to their breeding-places, which are sandy tracts, gravelly or pebbly ridges, rocky ground, sometimes low, shelving rocks on the sea-shore; their nests being bits of grass or fragments of sea-weed, placed in a mere depression. In stormy weather they fly little, but shelter themselves by resting on the shore. They go to roost very late in the evening; long after sunset, they are still engaged in seeking their sustenance."
Terns always assemble in flocks on the sea-coast, on the margins of lakes, in marshes, or wooded spots near the mouths of rivers, at their breeding-time. Their nests are placed so near to one another, that the hens sitting actually come in contact. They lay their eggs, to the number of two or three, which hatch in twenty days. These eggs are esteemed as a very delicate viand: in the United States a considerable trade is carried on in them.
The Sea Swallow is found in all the regions both of the Old and New World, Australia, and the islands of the Pacific.
The Tern (Sterna hirundo) is very common in France, on the shores of the Atlantic, and in the Mediterranean.
English Synonyms.—Lesser Tern: Montagu, Selby. Lesser Sea Swallow, Little Tern: McGillivray, Flemming.
Latin Synonym.—Sterna minuta: Latham, Flemming, Selby, McGillivray, Morris, Jenyns, Temminck.
French Synonyms.—La Sterne Petite: Figuier. La Petite Hirondelle de Mer: Temminck.
This smallest of the Terns has many habits in common with the Sterna hirundo. "In the elegance of its buoyant flight," says McGillivray, "as it skims over the water or shoots along its way to and from its breeding-place, the tiny creature is an object of 302 admiration to every lover of nature. You may see a pair coming up from a distance, flying at the height of a few yards over the waves, their long wings winnowing the air and impelling them on by starts as they wind their way in undulating and graceful movements. Suddenly their flight is arrested over a large pool left on the sands by the retreating tide. With quick beats of their wings they hover almost stationary over the water, with downward-pointed bills, intently searching for their prey beneath. One drops with upraised wings, dips for a moment, and rises with a small fish in its bill; the other is equally successful. Onward they proceed, now and then emitting their shrill cry. Far ahead is seen a flock engaged in picking up their prey, and onward the stragglers speed to join their kindred."
The Little Tern has the bill slightly longer than the head, and, like the Common Tern, slender, nearly straight, much compressed, tapering, and acute; the eyes and feet small; plumage soft and blended; wings long, narrow, and pointed; tail long and deeply forked; upper part of the head and nape black; neck, back, and wings light greyish blue; hind part of the back and tail white; length to the end of the tail about ten inches; wings twenty-one inches.
This species reaches our shores in the beginning of May, and settles along the whole eastern and southern coast, from the Land's End to the Orkneys, but is rare on the west coast. The Firth of Forth, the sands of Barry, near Dundee, a place at the mouth of the Don, and another at the Ythan, are noted as their haunts, as are the sands of Strathbeg Loch, and the sands between Burghead and the mouth of the Findhorn. It is also abundant on the sea-coasts of Holland and France, where it feeds on fish-spawn and small winged insects.
The Noddy (Sterna stolida), which frequents rivers and the borders of lakes, especially marshes, makes its nest among the reeds and water-lily leaves: this is the species most plentiful in America. The Silver-winged Tern (Sterna leucoptera) inhabits the bays and gulfs of the Mediterranean, and is only an accidental visitor to the north of France. The Arctic Tern (Sterna arctica) is a native of the Arctic Circle, and regularly visits the sea-coast of the north of France. We may also mention the Whiskered 303 or Marsh Tern (Sterna leucupareia), the Gull-billed Tern (Sterna anglica), the Roseate Tern (Sterna Dougalli), the Sandwich Tern (Sterna cautiaca), and the Tschegruna, or Caspian Tern (Sterna caspica), all of which either breed upon the British coast, or are frequent visitors there, although they rarely reach France.
The Scissors-bills have received their name from the conformation of their beaks, which are flattened laterally into two laminæ fitting one on the other, forming two mandibles compressed into cutting blades, the upper being one-third shorter than the lower. In order to pick up the shrimps and small fishes on which they feed, these birds are obliged to skim the surface of the water, dipping the lower mandible of their bill, the upper mandible being kept open and clear of the water till aquatic insects or other small fry have entered into the lower portion of it.25 The singular form of their bills is also of service to them in opening such bivalve shell-fish as come in their way. They frequently watch these mollusks, and when they notice that the shell of the latter 304 is slightly open, they plunge the lower mandible of their long bill into it; they then break the ligament of the shell by beating it against the rock. The tenement being thus destroyed, there is no obstacle to their devouring the inhabitant.
The only remarkable species of this bird is the Black Scissors-bill (Rynchops nigra), frequently called the Cut-water. It is about the size of a Pigeon; its prevailing colour is white, top of the head and shoulders black, with a white band on the wings. These birds are very numerous in the West Indian seas. They fly with a slow motion, and, like the Gulls and other sea-birds, they occasionally form such dense flocks that the sky is actually darkened for the space of a league.
Gulls and their congeners include the well-known shore-birds generally called Gulls, more especially the Skuas (Lestris), Gulls (Larus), and Mews (Gavia). They are characterised by a light body, more or less compact; neck of moderate length; head ovate; bill shorter than the head, straight, compressed; convex ridge on upper mandible, nasal groove long; lower mandible with the angle long and narrow; mouth moderate; tongue fleshy; eyes small; legs generally short; tibia bare; tarsus short, compressed; hind toe small; middle toe longest; fore toe moderate in length and slender; connecting membrane full, margins only concave; claws generally small, arcuate, acute, and more or less compressed.
These birds inhabit the sea-shore, along which they wander in search of food; the larger species preying on fish, crustacea and mollusca, and the carcasses of cetacea and other marine mammalia cast up by the sea. They all pursue shoals of fish in the open sea, often to great distances from land. Their plumage is full, soft, close, elastic, and well blended on the back and wings; wings long, broad, and pointed; the tail, of twelve feathers, rounded and forked.
The Sea Mews (Gavia) are connected with the Terns, yet still have some characteristics of the Gulls. However, they are of smaller size than the latter, have more slender forms, and their feet and bills are comparatively feebler. We shall 305 describe the Mews and Gulls under one head, as they have the same generic characteristics, the only difference between them being that of size. The name of Gull applies to those species which are at least as large as Ducks; that of Mew to those which are smaller.
The Gull (Larus) and the Mew are found in every country, on every coast, out at sea, and sometimes even on fresh waters, lakes, and rivers. These birds literally swarm on some coasts, where they devour every kind of food they meet with. Fish, either fresh or stale; flesh, either fresh or decomposed; worms; shell-fish—all are alike acceptable. If these birds happen to notice the carcass of any animal, either floating on the sea or cast up on the shore, it soon becomes their prey, and is speedily devoured by these "Sea Vultures," as Buffon calls them. Should one of them discover the remains of a dead whale, or other large oceanic mammalia, it apprises the rest of the flock, and immediately they all pour down upon their booty, uttering the most discordant cries. They gorge themselves up to their very throats; but their stomachs soon digest the rapidly-decomposing animal diet. They may also be observed in search of other prey, skimming over the surface of the water, their keen eyes anxiously scanning far and near for their most favourite food, young fish.
During the breeding season they visit islands where they are sure to find thousands of eggs as well as young birds. In spite of the piteous shrieks of the parents and the plaintive cries of the young, the whole colony is sacrificed to their gluttony; the eggs are sucked, and the scarcely-hatched young ones are devoured. But, as they are always cowards, whenever these sea-vagabonds notice the approach of a bird more warlike than themselves, although, perhaps, much smaller, their only endeavour is to hide themselves, or depart with all the celerity which their long wings can give them. The mere sight of a Labbe (Stercoraria) is quite sufficient to make them disgorge their food. These birds, which are essentially water scavengers, are frequently very much in want of food, especially during stormy weather. Nature in her goodness, however, has well enabled them to endure hunger.
Sea Gulls and Sea Mews are found everywhere, but they are most numerous on the flat and low sea-shores of the North, where 306 the dead bodies of whales and other large fish furnish them with abundant food. They prefer building their nests on desert islands in the Polar seas, where they are safe from man's intrusion. They lay two or three eggs in a hole scratched in the sand, or in the cleft of a rock.
These birds are easily tamed, and soon take to domestic habits; but their flesh, which is hard and tough as leather, is unfit for human food. In order to render them eatable in cases of emergency, the sailors, after having skinned them, hang them up by their feet, and leave them exposed to the evening dew for two or three nights. By this means a little of the disagreeable smell passed by their carcass is got rid of.
The most remarkable species of the Sea Gull are the following:—
The Large White-winged Gull, Larus glaucus (Fig. 108), is all white except its back, which is of a light bluish grey. It is most frequently found towards the east of Europe, and is rare on the Atlantic coasts.
The Great Black-backed Gull, Larus marinus (Fig. 109), is of a pure white, with a black back. It is very common in northern regions, and habitually visits the shores of the Atlantic to the north of France.
The Herring Gull (Larus argentatus, Yarrell), is white, with a 307 blue back. It is seen throughout the year on the coasts of the Mediterranean and the Atlantic.
The only species of Sea Mew which it is necessary for us to describe are:—
The White Sea Mew, or Senator (Larus eburneus),26 which is found but incidentally in the temperate regions of Europe. It is very common in Greenland and Baffin's Bay. Its plumage is entirely white, tinted with pink underneath; it has black feet and a bluish bill.
The Brown-masked Sea Mew (Larus capistratus)27 has the top of its head and throat of a light brown colour; the inside of the wings are light grey; the rest of its body is white; and its bill and tarsi are of a reddish-brown colour. This species is common in England.
The Laughing Sea Mew (Larus ridibundus)28 has its head black; its neck, tail, and lower parts of a white hue. Its back and wings are bluish grey, and its beak and feet vermilion red. This is the species most easily tamed. It is called the Laughing Sea Mew on account of its cry. It is widely spread all over Europe, and builds its nest on the coast at the mouths of rivers. It is only a visitor in France and Germany, but in Holland it is found a permanent resident.
308
The Grey Sea Mew, Larus canus (Fig. 110), is commonly called the Sea Pigeon. Its plumage is of a beautiful white colour with the exception of a grey back. When tempests threaten, this species disperses in flocks over the inland districts. It is common in summer in the regions of the Arctic Circle; in autumn and winter it is found on the sea-coasts of temperate and southern Europe.
The Skua, Labbe, or Dung-bird (Stercoraria, Vieillot), Fig. 111, is remarkable for its stout bill, which is nearly cylindrical, and covered with a membrane from the base as far as the nostrils; the upper mandible is convex, hooked, and armed at 309 the extremity with a crooked point, which almost appears as if it was supplementary. These birds principally frequent the sea-shore, but at the time of storms they venture further inland. They fly very rapidly, even against the strongest wind. They pursue the Sea Mews and the Terns most inveterately, and sometimes even Boobies and Cormorants, their only aim being to deprive these birds of the prey they have caught; for the Sea Mews and the Terns are their purveyors. Incessantly do they pursue, harass, and beat these species until they have forced them to disgorge and drop their booty: before the fish falls into the sea it is caught by the active persecutors. This singular habit has given rise to the belief that Skuas feed upon the excrement of the Sea Mew, and to this they owe their name of Dung-birds.
In some countries, as the Shetland Islands, these birds are held in veneration. The care and protection of the sheep are almost entirely intrusted to them, owing to their possessing an inveterate hatred against Eagles; for as soon as the monarch of the air appears in view, three or four of them combine together to give him battle. They never attack him in front, but harass him pitilessly until his strength is so reduced that they can completely conquer him, or at least force him to retreat. In recompense for these services, the inhabitants are in the habit of throwing to the Skuas the refuse of their fisheries.
These birds almost always live in solitude, so that they may be more readily able to procure their food, which consists of fish, mollusks, eggs, young sea-birds, and small mammals. They inhabit the Arctic regions of Europe and America, and make their nests in the heather; they lay from two to four eggs, which are sat upon by the male and female birds alternately. They are courageous enough to defend their young brood against any kind of animal, and even against man.
There are four European species: the Parasite Skua (Lestris parasiticus), which inhabits Greenland, Newfoundland, and Spitzbergen, and visits tolerably often our Atlantic coasts; Richardson's Skua (Lestris Richardsonii), which is very plentiful in Sweden, Norway, Lapland, and North America; the Pomerine Skua (Lestris pomarinus), which is very common in Newfoundland, 310 Iceland, and the Feroë Islands; the Common Skua (Lestris cataractes), commonly called the Brown Stoëland.
The Petrels (Procellaria, Linn.) are characterised by a gibbous beak, the extremity of which is hooked, and seems made all in one piece, and as if jointed on to the rest of the upper mandible. These birds never dive, and rarely swim; but in their rapid flight they skim over the waves, and actually appear to walk upon the waters. To this habit they owe the name of Petrel, which simply means "Little Peter," in allusion to the miracle of St. Peter, who walked upon the restless waters of the Lake of Genesareth.
The family of the Petrels contains several species of very different appearance. They traverse immense distances in their powerful and rapid flight, although they nearly always keep close to the water. They never draw near to the coast except to build their nests, for which purpose they select a little crevice in some steep rock, in which they deposit a large white egg. While sitting upon it, they keep up a low and continual noise, like that of a spinning-wheel.
In general, Petrels are not of a very engaging aspect; but they are an invaluable resource to the poor people who inhabit the islands in the frigid seas, who do not object to eat the flesh of these birds, although they principally value them for their warm down and the oil which can be extracted from their stomachs. The quantity of oil which these birds contain is so large that it is used as an article of diet. In the Feroë Islands candles are made from this oleaginous matter. Often, indeed, the islanders 311 make the bird itself serve as a candle to illuminate their gloomy vigils. This is performed by passing a wick through the body of the bird when just killed.
These birds appear to love the tempest; they run over the roughest waves, and seem as if they were enjoying themselves as they pass up and down the declivities of the mountains of foam. When the storm is too violent for them, they take refuge upon the nearest rocks, or even on the yards of a passing ship. Sailors, who are confessedly simple and superstitious, take these birds for evil spirits, birds of the devil, harbingers of storms, and so forth, simply because they more frequently see them during a storm. Their black plumage tends to confirm the sailor in his superstition.
When the vessels sent to the whale fishery have passed the Shetland Islands, and entered the northern seas, which are almost always very rough, the Petrels are seen flying about amidst the eddies of foam which are formed by the movement of the ship. They keep in attendance until something is thrown overboard, for they are extremely voracious, and especially fond of fat, particularly that of the whale. When the fishermen begin to cut up a whale, the Petrels flock together to the number of several thousands. They are not afraid to approach within reach, so that they may be taken or killed with a blow from a boat-hook. Their plumage is so close, that shot fired at them, except at close range, will not penetrate.
Petrels walk on land with much difficulty. When they require rest in the open sea, with their heads placed under their wings, they sleep on the water, allowing themselves to be borne about at the mercy of the wind.
The most remarkable species are—the Giant Petrel (Procellaria gigantea), commonly called the Bone-breaker, which inhabits the tract of ocean between Cape Horn and the Cape of Good Hope; the Chequered Petrel (P. capensis), commonly called the Chequered Pintado, which is a native of the southern seas; the Fulmar Petrel (P. glacialis), which inhabits the Arctic seas; the Stormy Petrel (P. pelagica), commonly called the Storm-bird, which frequents the seas of Europe, and after a hurricane appears on the northern coasts of France; the Forster or Blue Petrel 312 (P. Forsteri or cærulea), Fig. 112, commonly called the Blue Petrel, which inhabits the Antarctic seas.
Under the name of Puffins those species of Petrels are included which have bills as long, and sometimes longer, than their heads, and their nostrils in two distinct tubes. Among these are the Grey Puffin (Puffinus cinereus), which is very common in the Mediterranean, and builds its nest in Corsica; the English Puffin (Puffinus anglorum), which inhabits the northern regions of our hemisphere; the Brown Puffin (Procellaria æquinoctialis), which inhabits the Southern Ocean, and is frequently met with at the Cape.
The Albatross29 is the largest and most bulky of all the birds which fly over the surface of the sea. It belongs principally to the southern hemisphere. The sailors know it under the names of Cape Sheep and Man-of-war, which they give it on account of its enormous size. Its extended wings measure as much as five 313 mètres across.30 Its plumage is generally white, with the exception of a dark back. Courage is not measured by size. This rule holds good in these birds, for, notwithstanding their wonderful strength and their large, strong, sharp, and hooked bills, they exhibit the most unaccountable cowardice. Even a poor weak Sea Mew will attack an Albatross, and endeavour to tear its stomach open. The pusillanimous Albatross can find no better means of getting rid of his enemy than by plunging into the water. Although they are most gluttonous in taste, they prefer to fly away rather than contend for their food. This consists of small marine animals, mollusks, mucilaginous zoophytes, and the eggs and spawn of fish. They will even swallow large fish without tearing them to pieces. When they are completely gorged, and the fish which they have seized is too large to swallow whole, they may be seen with part of it hanging outside their bill, until the first half of their prey is digested. The same is done, as is well known, by several kinds of Serpents. When thus embarrassed, the Albatross has only one mode of escape if it happens to be pursued; namely, by disgorging the food with which its stomach is overloaded.
Gifted as they are with an extraordinary power of flight, these birds venture out to enormous distances from all land, more especially in stormy weather. They seem to delight in the warring of the elements. When overcome with fatigue, they take repose on the surface of the sea, placing their heads under their wings. When in this position they are very easy to capture: in order to do this, the sailors have only to approach silently, and knock them down with a boat-hook or spear them with a harpoon.
Navigators have found opportunities of observing these birds in the Polar regions, where there is no night during half the year. They see the same flocks hovering around their vessel during many successive days without exhibiting the least signs of fatigue, or the slightest relaxation in their strength. The peculiarity in their mode of flight is that, whether they are ascending or descending, they seem to glide, for they flap their wings but seldom. 314
To follow in the wake of some passing ship, probably because the agitation of the waves brings to the surface the small fry of marine animals which are their principal food, appears to delight them. They also pounce upon anything that falls overboard, even though it should be a man. On one occasion a sailor fell into the sea from a French vessel, and could not be immediately rescued because there was no boat in a fit state to be lowered. Before such could take place, a flock of Albatrosses which followed in the ship's wake pounced upon the unfortunate man, and commenced to peck his head and arms. Being unable to buffet both with the sea and the enemies which surrounded him, the man perished under the very eyes of his comrades.
The Albatrosses and Petrels may be said to be the Vultures of the ocean. They may also be said to be its scavengers, for they cleanse the sea of all the putrefied animal substances which float on its surface.
At the breeding season, which varies according to the hemisphere inhabited by them, the Albatrosses arrive at their favourite haunts, generally in an exhausted state; but, however thin they may be, they soon grow fat upon the abundant supplies of food which they find in the vicinity. In the end of September, to build their nests, they go in immense numbers to the island of Tristan d'Acunha, in the South Atlantic Ocean. Their nests, which are about three feet in height, are formed of mud. Their flesh is very hard, and can only be rendered eatable by laying it in salt for a long time, and afterwards boiling it, flavouring it with some piquant sauce. Nevertheless sailors, as well as the inhabitants of the desolate southern regions, use it, but only in the absence of better food.
The most remarkable species are—the Common Albatross (Diomedea exulans), which frequents the seas washing the south of Africa; the Black-browed Albatross (D. melanophrys), which also inhabits the seas round the Cape of Good Hope; the Brown Albatross (D. fuliginosa); the Yellow and Black-beaked Albatross (D. chlororinches), which, like the preceding species, inhabits the seas of the South Pole.31

The most striking characteristic of the Waders consists in the nakedness and length of their tarsi, which sometimes attain to really extraordinary dimensions: some of these birds look as if they were mounted on stilts. This peculiarity of conformation is, however, well adapted to their modes of life. They inhabit, for the most part, river-banks, lakes, and marshes, in which they find their sustenance; consequently, they are fearless of water and ooze. The Agami, the Bustard, and the Ostrich, as well as the Emu and other Struthionidæ, which are placed by naturalists with this family, are not aquatic; they inhabit the interior of the country, and are either herbivorous or granivorous.
The bills of these birds assume very various forms. They are generally long; but, according to the species, they may be thick or slender, tapering or flat, blunt or pointed, strong or weak; and in some kinds, such as the Flamingo, the Spoonbill, and the Boatbill, they really defy all description. The neck is always slender, and in perfect harmony with the length of the legs.
Almost all the Waders are birds powerful on the wing, and twice a year most of them undertake long journeys, which they perform in large flocks, like as do Ducks, Geese, and Swans. There are, however, exceptions to this rule. Some of them—the Bustard, for instance—move through the air with difficulty, although their inferiority in this respect does not reach to complete inability; others, as the Brevipennæ, are absolutely unable to fly at all: their wings being altogether rudimentary, are only useful for accelerating their pace in running, and thus assisted they are remarkably swift. 316
The nature of their food varies with the form and strength of the bill and the locality they inhabit; it consists generally of fish, small batrachia, mollusks, worms, and insects; sometimes of small mammalia and reptiles, and more rarely of grasses and seeds. This kind of sustenance must be wonderfully fitted to develop the savoury qualities of their flesh, for it is among this class that we find our most delicious specimens of "game." The mere mention of the Woodcock, Snipe, Plover, Pewit, and Bustard is sufficient to establish their claim upon the epicure. Some kinds, which are utterly devoid of any culinary properties, are furnished with a plumage to which ladies owe some of their most brilliant adornments. The Ostrich and Marabout feathers, and those of the Heron, are keenly appreciated by many fair ones, whose beauty the feathers are supposed to greatly enhance. In short, this order of birds possesses two important qualities—worthily ministering to the taste of the most fastidious palate, and handsomely decorating with its gorgeous plumage our fashionable and wealthy belles. Gormandising and coquetry alike find satisfaction, and derive from these birds some of their most agreeable sensations. If they had the additional gift of melody they might lay claim to perfection; however, such is not the case, as their notes are shrill and discordant.
The Waders are monogamous or polygamous according to their species; but their history furnishes us with some touching instances of conjugal attachment. They make their nests either on trees, buildings, or the surface of the earth; sometimes even in the middle of the water, among the reeds, sedges, and other aquatic plants. In general, they evince but little care in the construction of their progenies' birth-place. In most cases they are contented to collect together a variety of substances without much discrimination; sometimes they merely scratch a hole in the ground, in which they deposit their eggs without any further care.
The Waders are usually divided into six great families, which are again divisible into many genera. Following Cuvier's classification, with some slight modification, we propose arranging the group as follows:—I. Palmidactyles, II. Macrodactyles, III. Longirostræ, IV. Cultrirostræ, V. Pressirostræ, and VI. Brevipennæ. 317
Have the anterior toes united by a wide membrane; the hind toe is absent, or is very small; the legs are very long and smooth; from their webbed feet they may appear to belong to the Palmipedes, but the arrangement of their toes is altogether different, and constitutes them most strikingly characteristic of the order of Waders.
The Flamingo is one of the most curious of the tribe of Waders. The most fanciful imagination would fail in picturing to itself anything more odd than the conformation of this bird. Extremely long legs, supporting quite a small body; a neck corresponding in length with the legs; a bill rather long than otherwise, sharply curved and broken, as it were, in the middle, contrived probably to discourage those who are tempted to describe it; wings of a middling size, and a short tail—such are the distinctive features of this remarkable-looking bird. The long legs terminate in equally long feet, with three toes in front 318 hind toe articulated high up the tarsus, and very short; anterior toes united by a deeply-indented membrane. Add to this a plumage of a splendid rose-colour, warming into a bright red on the back and wings, and we have an object calculated to excite both wonder and admiration.
Ancient writers, struck with the vivid colouring of its wings, gave the Flamingo the designation of Phœnicopterus (fiery-winged): this term was popularised in France by the word Flambant, or Flamant: hence the name by which the bird is universally known.
Flamingos inhabit the margins of lakes and ponds, more rarely the sea-shore, or the banks of rivers. They feed on worms, mollusks, and the spawn of fishes, which they capture by the following stratagem: they place their long neck and head in such a position that the upper mandible of their bill is the lowest; then, by stirring the mud about in every direction, they easily succeed in disturbing the small fish which have settled in it, and afterwards in capturing them. They also use their feet for working the ooze and uncovering the fry and spawn to which they are partial. They love company, and live in flocks, which are subject to strict discipline. When they are fishing they draw themselves up into long, straight, and regular files, placing a sentinel, whose office it is to give a signal of alarm on the approach of danger. If any cause for uneasiness should arise, the scout-bird gives a piercing cry, not unlike the note of a trumpet, and the whole flock immediately take wing in perfect order.
Flamingos are very shy and timid birds, and shun all attempts of man to approach them; the vicinity of animals, however, they disregard. Any one who is acquainted with this fact can take advantage of it so as to effect slaughter of these beautiful creatures by dressing himself up in the skin of a horse or an ox. Thus disguised, the sportsman may get close to them and shoot them down at his ease. So long as their enemy is invisible they remain immovable, the noise of the gun only stupefying them, so that they refuse to leave, although their companions are dropping down dead around them.
Some authors have asserted that the Flamingo makes use of its long neck as a third leg, walking with its head resting on 319 the ground like a foot. The fact that has doubtless given rise to this supposition is the position of the neck, necessitated by its peculiar method of seeking food. We are told, it is true, about a Flamingo reared in captivity which, being accidentally deprived of one of its limbs, found out a remedy for its infirmity by walking on one leg and helping itself along by means of its bill, using the latter as a crutch; the master of the bird, noticing this, fitted it with a wooden leg, which it used with the greatest success. But this story, which applies very well to a domesticated bird which was maimed, and consequently under peculiar conditions, in no way invalidates our former observations.
The Flamingo makes itself a nest which is as original as its own personal appearance. It consists of a truncated cone, about twenty inches in height, and formed of mud dried in the sun. At the summit of this little hillock it hollows out a shallow cavity, in which the female lays two eggs, rather elongated in shape and of a dead white colour. When she is incubating them she sits astride on this novel description of throne, with her legs hanging down on each side. The young ones run about very soon after they are hatched, but it is some time before they are able to fly—not, indeed, until they are clothed with their full plumage. At two years old they assume the more brilliant colours of the adult bird.
The Flamingo is found in all the warm and temperate regions of the globe. On certain islands off the American continent they exist in such numbers, that navigators have given them the name of the Flamingo Islands. In the Old World they are found spread over a region below the fortieth degree of latitude, principally in Egypt and the Nile tributaries: during the summer they seek a cooler climate, and they are then seen in numerous flocks on the southern coasts of France. The height of these magnificent birds reaches to about five feet; when they are flying, in the peculiar formation common to most aquatic birds, with the neck stretched out and the legs sticking out behind, they look, in the clear sky, like gigantic triangles of fire. The spectacle they then present is at once beautiful and wonderful.
The ancients greedily sought after the flesh of the Flamingo, which they regarded as the most choice food. The tongue especially 320 was thought to be an exquisite dainty, and the Emperor Heliogabalus appreciated it so highly that a body of troops was exclusively employed in slaughtering Phœnicopteri to satisfy his gastronomical tastes. At the present day we no longer eat the bird; to modern palates its flesh is disagreeable in flavour, and it retains a marshy smell which is far from being pleasant. With regard to the tongue, the Egyptians, it is said, are content with extracting an oil from it, which is used to flavour some descriptions of viands. We must add, in order to complete our account of the Flamingo, that it is covered with down like a Swan, which is employed for the same purposes, and that its thigh-bone is used in some countries in the manufacture of flutes.
The Avocet (Fig. 115) is characterised by a very long and slender bill, flexible, and curved upwards; this latter peculiarity has procured for it the name of Recurvirostra (curved beak). It uses this strange implement to rake up the sand and mud to a pretty good depth, in order to catch the worms, small mollusks, and fish-spawn which constitute its chief food. Its long legs enable it to travel in safety over swamps and lagoons; it also swims with great ease. It may often be seen looking for its food in the very centre of lakes and ponds.
The Avocet stands about twenty inches in height, although its body is but little bigger than that of a Pigeon. It is a pretty bird, of slender make; its plumage is black on the head and back, and white underneath. It is to be met with on both the Continents; the European species is common in Holland and on the French coast. It is wild and shy in its nature, and very difficult of 321 approach. It is clever in avoiding snares set for it by the fowler, and ingenious in escaping—either by flight or swimming—its pursuers. The nest of the Avocet is a very simple structure, generally made by placing a few blades of grass in a hole in the sand. Here it lays two or three eggs, of which it is frequently robbed; for, like those of the Plover and others, its congeners, they are regarded as great delicacies by the gourmand. The flesh, however, is not considered very tempting.
The Stilt Birds obtain their name from the excessive length of their legs, which are also so slender and flexible that they can be bent considerably without breaking. Their feet are not so completely webbed as the species we have just mentioned: the two membranes which unite the toes are unequal in size. The bill is long, slender, and sharp, like that of the Avocet, but straight; the wings are long and pointed; the tail small. They are about the size of the Avocet, and sometimes 322 attain the height of six-and-twenty inches. They possess considerable powers of flight, but walk with difficulty; on the other hand, they are much at home on mud or in marshes and swamps, in which they bore with their long beaks for insects, larvæ, and small mollusks—dainties to which they are very partial.
They are dull, shy birds, leading a solitary life, except at the breeding season. At that period they assemble in great numbers, build their nests in the marshes, on little hillocks, close to one another, grass being the principal material employed. They lay four greenish-coloured eggs, with ash-coloured spots. The male bird watches while the females are sitting; and at the slightest alarm he raises a cry which startles the flock. The whole colony may then be seen on the wing, waiting for the danger to pass before settling down.
Stilt Birds are uncommon in Western Europe; they are principally to be met with in the Russian and Hungarian marshes. During the summer they occasionally visit the shores of the Mediterranean, but they are seldom seen on those of the Atlantic. By sportsmen they are little thought of.
The birds forming the family of Macrodactyles (long-toed) are remarkable for the extreme length of their toes, which are entirely separate, or but slightly webbed; they are thus enabled to walk on the weeds growing on the surface of the water. In most instances the shortness of their wings limits their powers of flight.
This order includes the Water Hens (Gallinula), the Taleves, or Sultana Hens, the Rails (Rallus), the Coots (Fulica), the Glareolæ, and the Kamichis.
The chief characteristics of the Water Hen are a short and strong bill, thick at the base and sharp at the end, with a prolongation of it extending up the forehead; four well-spread toes, furnished with sharp claws—the three front toes united by a small and cloven membrane. They are plentiful in some parts of 323 the globe, their favourite haunts being marshy places and the banks of lakes or rivers, where they feed on worms, insects, mollusks, and the smaller fish. They are lively, graceful, and ornamental birds. During the day they love to lie hid among the reeds, shaded from the sun's rays by the large leaves of the water-lily. They emerge from their hiding-places at evening and morning in search of food.
Although incapable of either fast flight or rising to great elevations, the Water Hen shows considerable address in escaping from the sportsman's gun. When pressed very closely, they take to the water, in which they are expert swimmers and divers: under the water they go, to reappear on the surface many yards away, where they only show themselves above for a moment to breathe, avoiding flight until every cause of fear is removed.
In some countries they remain throughout the year; in others, on the contrary, they are migratory. When the latter is the case, they travel sometimes on foot, sometimes by swimming, and sometimes on the wing; following the same route, however, year after year, and always returning with constancy to the spot where they made their first nest.
The eggs are seven or eight in number. During incubation the male and female occupy the nest alternately. Should any intruder alarm them, they never fail, before leaving the nest, to cover up their cherished treasures with grass or other material, so as to keep them warm and hidden from the voracity of their watchful enemy, the Crow.
Immediately after the young are hatched they leave the nest to follow their mother, and are very soon able to supply their own wants. Their only covering at first is a scanty and coarse down; but they run rapidly, and seem almost instinctively to swim and dive and conceal themselves at the slightest appearance of danger. Young Water Hens, however, are exposed to accident from the flooding of streams, and consequent submersion of the nests; and it is probably by way of compensation for this that nature has made them so prolific, for frequently they rear three broods per annum.
The Common Water Hen (Fig. 117) is a native of Europe; 324 it is found in France, England, Italy, Germany, and Holland. The Slate-coloured Water Hen is a native of Java.
The Purple Water Hen (Porphyrio hyacinthus, Temminck), or Sultana Fowl (Fig. 118), is peculiarly characteristic of Macrodactyles, and might be defined as an exaggeration of the Water Hen. Its bill is thicker and more robust, the frontal plate on 325 the forehead is more extended, the toes are longer, but its habits are very nearly the same. It is, however, less exclusively aquatic, and its favourite food is the seeds of the cereals and aquatic plants, and fruits: it occasionally, however, feeds on mollusks and small fishes. When eating, it stands on one foot, and uses the other as a hand in order to convey the food to its beak.
The body of this magnificent bird is of an indigo-blue colour, the beak and feet being rose-colour. The ancients, who were acquainted with it, and were accustomed to rear it in a domesticated state, gave it the name of Porphyrio (purple coloured) on account of its colour. If it could be acclimatised, it would be a valuable addition to our ornamental grounds.
There are several species of the Sultana Fowl, differing more or less from one another. They inhabit the warmer regions of the Old World. The Purple Water Hen is found in Greece, Asia Minor, Africa, and the South of Europe; generally, it is about the size of the ordinary Domestic Fowl.
Rails (Rallus) are characterised by a slender, tapering, slightly-arched beak, longer than the head; elongated tarsi, terminating in slender toes, much compressed and completely separate, and not marginate; wings middle-sized; tail short.
Their habits bear a strong resemblance to those of the Water Hen. Like the latter, they are timid, and hide themselves all day in the rushes, underwood, or grass of the marshes and meadows they inhabit. They make use of the holes hollowed out by water-rats, in which they take refuge when hard pressed. Little thickets 326 bordering brooks and small rivers are localities to which they are peculiarly partial, inasmuch as they assist ready concealment from their enemies. Their flight is slow and heavy, and is generally directed in a straight line, but little elevated above the ground. Running, however, is the means they usually adopt for escaping their pursuers, and by their numberless turns and windings they often succeed. But in some cases their efforts are of such a feeble character that dogs catch them without difficulty, and even the sportsman has been known to capture one with his hands.
Rails are solitary, differing in this from the majority of migratory birds, which generally assemble in flocks previous to undertaking long journeys.
The nest is roughly constructed among the reeds and flags of some quiet pond or river bank. The females lay from six to eight eggs. The young ones run as soon as they are hatched, and grow very rapidly. Their favourite food is worms, insects, and shrimps, but they do not reject wild corn and other seeds. Their flesh is considered delicate, and is certainly superior to that of the Water Hen: in the autumn it acquires an exquisite flavour in the estimation of French gourmands.
Rails are very common in France. The species most abundant there is the Land Rail, which is thus named from its habits being more terrestrial than aquatic; besides, it gives a very decided preference for fields, copses, heaths, and meadows. It is vulgarly called the "King of the Quails," probably from frequenting the same localities. They do not acquire their most perfect condition till the end of summer; this, therefore, is the proper time to kill them. Twenty species of Rails are enumerated, which are spread over the various countries of the globe. However, the characteristic features of all are nearly alike.
The Coot (Fulica) has a bill of moderate size, stout, tapering, much depressed, with a well-developed frontal plate; the toes are slender, and edged with a broad, scalloped membrane. Their plumage is glossy, soft, full, and blended, and impervious to water.
Coots are essentially aquatic, frequenting lakes, pools, and marshes, and sometimes the shores of estuaries, bays, and gulfs. 327 Like the Water Hen and the Rail, their life is almost nocturnal. During the daytime they hide themselves amid the reeds and flags, from which they do not emerge until the evening, when hunger forces them to seek their food. This consists of worms, small fishes, and the young shoots of aquatic plants. Coots but rarely visit the dry fields, where they move about with great difficulty; on the other hand, they swim and dive with graceful ease. Their flight is somewhat less feeble than that of the Rails; still it is far from strong.
Coots herd together in flocks; they make their nests on the reeds in the water, and lay from eight to fourteen eggs. The young ones take to the water as soon as they are hatched, but they often fall a prey to the Marsh Harrier. It sometimes happens that the whole brood is destroyed in this way: when such is the case the female lays a second batch of eggs, which she hides in the most retired spot, less accessible to the enemies of her race.
The Coot is found in every country in Europe, in North America, in Asia, and in Africa. Its flesh, which is white and delicate in appearance, is usually very fat, but has a disagreeable 328 taste and marsh-like odour. Three species are known, only one of which is found in this country—namely, the Bald Coot (Fulica atra), the Foulque macroule of French naturalists, very common in the north of France, and all quarters of the Old and New World; the Crested Coot (F. cristata), a native of Madagascar, but sometimes a visitor to the South of Europe, and differing very little from the Common Coot, but distinguished from it by the red and prominent bony protuberances at the top of the frontal plate; and the Blue Coot, which is described as an inhabitant of Portugal.
The Glareola, or Sea Partridge (Glareola perdix), has the bill short and curved, the tarsi long and slender, the middle toe joined to the outer by a small membrane, the wings long and pointed, the tail forked. They live in flocks on the banks of the Danube, the Volga, and on the shores of the Black and Caspian Seas. They feed on worms, water-insects, and especially locusts, which they catch on the wing.
The Jacanas or Parræ are characterised by a straight and 329 middle-sized bill; legs armed with pointed spurs; toes furnished with long and sharp-pointed claws, and a back toe longer even than the front ones. These birds inhabit Asia, Africa, and South America. In Brazil they are called "Surgeon-birds," from the resemblance the claw on their back toe bears to a lancet. They frequent swamps, lagoons, and the margins of pools. They walk on the wide-spreading leaves of tropical aquatic plants with perfect ease, although they swim very imperfectly: some naturalists, indeed, declare that they cannot swim at all, and they are probably justified in this opinion by the appearance of the bird, which seems to have few characteristics of an aquatic species. Their flight is rapid, but not very high.
The Jacanas live in pairs. They are exceedingly numerous, and perfectly fearless of man. They are restless and quarrelsome in their nature, frequently engaging in conflict with other birds, when they make good use of their spurs. They will defend their offspring with daring courage even against man himself, and will sacrifice their lives without hesitation in their defence. The male and the female evince the tenderest mutual attachment; once united, they part no more during life. They make their nest in a clump of flags or other aquatic plants, in which the 330 female lays four or five eggs, on which she sits during the night only, the high temperature produced by a tropical sun supplying the necessary warmth. As soon as hatched the young ones leave the nest, and are able to follow their parents about.
The Common Jacana is black, with neck and shoulders of a reddish brown, and green wing-feathers.
In the Kamichi, or Horned Screamer (Palamedea cornuta), the beak is shorter than the head, slightly compressed, and bent at the point; the wings are wide-spreading, and provided with strong spurs on the shoulders; the toes are separated, and furnished with long, stout, and pointed claws. Their plumage is of a blackish 331 hue. Their size is about that of a Turkey. They are South American birds. Their favourite haunts are moist, marshy localities, inundated savannahs, or the oozy banks of shallow streams. Although they do not swim, they venture on the water in search of aquatic plants and their seeds. Some naturalists, founding their belief on the presence of spurs with which this bird is provided, assert that it attacks small reptiles and destroys them. This is now acknowledged to be an error. These birds live isolated, in pairs; they are mild and peaceful in their nature, for the breeding season is the only time when they seem at all disposed to use their weapons. At this period the cocks engage in deadly conflict to gain possession of some favourite mate. The union once formed, it is indissoluble, and only terminates with the death of one of them. It is even asserted that the survivor exhibits signs of great affliction, lingering 332 for days near the spot where cruel fate had severed him by death from the loved one.
The Palamedea has many points of resemblance to the Gallinaceous order: its comparatively short and thick tarsi, its general make and gait, its habits of life and inoffensive nature, all remind us of the above-named tribe. There is, therefore, no reason for surprise in the fact that man has succeeded in domesticating them, and even in turning them into useful assistants.
The Horned Kamichi is thus named on account of having on its head a horn-like tuft, which is straight, thin, and movable, about three inches long.
The Chaja, or Faithful Kamichi, has, instead of the horn, a crest of feathers arranged in a circle on the back of its head. This species is susceptible of education. It is easily tamed, and becomes very friendly with man, proving itself an active, intelligent, and devoted servant. It becomes at once the companion and protector of the other denizens of the poultry-yard—so much so, that in Brazil and Paraguay, where it is known solely as the Chaja, the inhabitants have no hesitation in confiding to its charge the care of their flocks of poultry. The Chaja accompanies them into the fields in the morning, and at nightfall conducts them back to their roosting-places. Should any bird of prey come near, the guardian spreads out its broad wings, darts upon the intruder, and soon makes him feel what a love of justice can do when aided by four stout spurs.
The birds composing this family are characterised by a long and flexible bill, which is fitted for little else except boring in mud and soft ground. They are indifferently shore or marsh birds. Among them are comprised the Sandpipers, Turnstones, Ruffs, Knots, Godwits, Woodcocks, Snipes, Curlews, and Ibis.
The Sandpipers have a long, straight, thin bill, flexible at the base, but firmer towards the point; the tarsi are slender and elongated; the wings very pointed; the feet half webbed, the back toe short, and touching the ground with the point only. They 333 live in small flocks on the banks of rivers and on the sea-coast. Some species frequent marshy localities, others dry and sandy districts. Their food is chiefly worms, insects, fish-spawn, and sometimes even small fry and crustacea. Their habits are peaceable, and their movements easy and graceful. They may be noticed on the strands and banks of our rivers, incessantly on the move, running, swimming, and diving, all of which they perform with equal ease. They are gifted with a keen sight, for not even the smallest insect in its vicinity can escape its vision. The moment one of them descries a prey, the whole flock vie with each other to obtain possession of it.
The Sandpipers are natives of the northern parts of the Old and New World; they visit France twice a year—in spring and autumn. They breed in the North, and lay from three to five eggs. The extreme delicacy of their flesh causes them to be much sought after by epicures; they are, therefore, captured in every possible way. Extinction will probably be the result. To gratify the tastes of the gourmand and the bloodthirsty instincts of the poacher, the lovers of nature are, forsooth, to be deprived of one of the most innocent and beautiful families of birds.
In France seven species of Sandpipers are known, varying in 334 size from that of the Sparrow to that of the Thrush. They are as follows:—the Brown Sandpiper, called also the Harlequin Sandpiper (Totanus fuscus), the Greenshank (Totanus glottis), the Redshank (Totanus caledris), Fig. 125; the Pond Sandpiper; the Wood Sandpiper (Totanus glareola), the Green Sandpiper (Totanus achropus), the Common Sandpiper (Totanus hypoleucos). The last kind is the smallest, and also the most prized.
The Turnstones (Strepsila) inhabit the sea-coasts of both continents. A single known species alone has been traced over most parts of Europe, the Cape of Good Hope, and various parts of Asia, Australia, and North America. It owes its name to the peculiar method it adopts to find its food. This habit consists of lifting up the pebbles and shingles which lie spread over its domain, the sea-shore, in order to discover the worms, crustacea, and insects concealed underneath. For this purpose it is provided with a bill of medium length, tapering, pointed, and hard, which it uses adroitly as a lever. It lives a solitary life, and does not even congregate with its own species for the purpose of migration, but travels alone. Only in the North, whither it repairs to breed, does it manifest any approach to sociability. The female lays three or four rather large eggs of an ashy-grey 335 336 colour; these are deposited in the bottom of a hole dug in the sand on the shore. The young ones are very precocious, for even on leaving the shell they run about with their parents to seek their sustenance.
The only species of this genus, the Ringed Turnstone, Strepsila interpres (Fig. 126), is a bird of passage in France and England. Its flesh is not without relish, but by no means equal to that of the Plover.
The Ruff (Machetes pugnax, Temminck) commends itself to the attention of the observer by the sudden metamorphosis which seems to revolutionise its entire nature, in the early days of May, at the first dawning of that charming month when all nature appears to expand and array itself in every kind of splendour, the better to render homage to the Creator. At this season the plumage of the Ruff, which has hitherto been grave and almost sombre, undergoes a most brilliant transformation. It would strike the observer as if the agitation of love had the effect of totally changing its plumage from one altogether devoid of display to the most brilliant costume imaginable, for its neck is now wreathed with a glittering collar, which extends by degrees over shoulders and breast. On the top of its head, to the right and left, two graceful plumes come forth, which vastly improve its looks, and contribute in no small degree to the impressiveness of its demeanour. Brilliant hues of yellow, white, and black, arranged in a hundred ever-varying shades, combine to improve their plumage, making them most attractive to look at.
This physical transformation produces a change in the temper of the bird. Puffed up with pride, and elated at his own personal magnificence, our hero suddenly finds himself subject to the most warlike feelings.
But what is this object which catches his sight? It is another Ruff—a rival. Without hesitation he rushes immediately to meet the stranger, who, nothing loath, charges in return at the top of his speed. With stretched-out beak and crest erect, the two adversaries impetuously close. A furious duel takes place, carried on in the sight of the feebler sex, who pass their opinion on the blows which are given and received, praise or blame them, and, by a cry at judicious 337 338 movements, reanimate the failing ardour of the gallant combatants. Fierce blows with the beak follow one another in quick succession, blood soon flows, and the arena is reddened around them, until at last the two weary champions roll over in the dust, and lie side by side completely exhausted. During two or three months these duels are of frequent occurrence, and cannot fail to leave numerous gaps in the ranks of the species.
In the beginning of August their rich vestments gradually disappear, and the warlike fever as rapidly abates. The Ruff now becomes a commonplace bird of peaceful habits, with no other occupation but that of searching for worms and insects on the shores of the ocean. Then is the time when they fall under the sportsman's gun and into the snares of the bird-catcher.
The Ruff soon gets accustomed to living in captivity. In England, where they were formerly very numerous, and in Holland, where they are probably so still, Ruffs are reared and fattened for the table. They must, however, be kept in the dark during the breeding season, to prevent them from giving way to their turbulent tempers, which blaze out on the slightest excitement under the influence of light.
These birds inhabit the northern and temperate countries of Europe and Asia: in France they are common enough on the north and north-west coast of the Channel. In spring they fix their abode in moist and marshy meadows, where they lay their eggs, four or five in number, of a greenish-grey hue, speckled with small brown spots. In the autumn they spread themselves along the sea-shore. Their size nearly equals that of the largest of the Sandpipers.
The Knot (Tringa, Linn.) has a bill as long as the head; the toes divided, the back toe short; the wings pointed; a shape rather heavy and thick-set. They frequent the sea-shore and salt marshes, and, except by accident, never venture far inland. They are natives of the Arctic Polar Circle, and visit our coasts in the spring and autumn. They lay their eggs, four or five in number, in their northern retreats. 339
The Sanderlings (Caledris) and the Curlews (Numenius, Latham) are species closely allied to the Knots, but differing in their habits and physical characteristics. They visit all the coasts of Europe in small flocks, incessantly on the move. Even an abundance of food does not suffice to keep them very long in the same locality: motion seems the law of their existence.
The Woodcock (Scolopax rusticola) has a very long, straight, and slender bill; the head flattened; the tarsi short; and the legs covered with feathers. They live in the woods, and do not frequent the sea-shore or river-banks. They differ from the Snipes in having the body fuller, the tibiæ feathered at the joint, the tarsi shorter, the wings broader, and the bill firmer (Fig. 129). They are also larger in size. In points they differ from most of the Grallæ; but, taken as a whole, it has been thought right to place them among this order.
The Woodcock inhabits, during the summer, the lofty, wooded mountain-ranges of Central and Northern Europe. Driven away by the severe cold, they descend into the plains, and reach France and England about the month of November. They are shy, timid birds, and conceal themselves all day long in the depths of the most retired woods, busying themselves in turning over the leaves with their bills to catch worms and grubs, which form their 340 food. The brightness of daylight prevents their seeing clearly, and they do not possess full power of their visual faculties until evening, when they emerge from their retreats, and seek their sustenance in the cultivated fields, damp meadows, or in the vicinity of springs.
Woodcocks do not all migrate, but remain throughout the year in the neighbourhood of springs which the most bitter cold cannot freeze. Solitary during the greater part of the year, they pair in spring; building their nest on the ground with grass and roots, placing it close to the trunk of some tree (the Scotch fir by preference, it is said), or in a holly-bush. The female lays four or five oval eggs, rather larger than those of a Pigeon. The young ones run about as soon as they are hatched: the parent birds guard them with careful solicitude, and manifest on all occasions the greatest love of their offspring. If any danger threatens, the old birds catch up their young, holding them under their necks by means of their beaks, and afterwards transferring them to a place of safety.
These birds seem always to feel an affection for places they have once frequented, and love to return to them; the following fact, at least, would lead one to think so. A gamekeeper, having snared a Woodcock, gave it its liberty after 341 fastening a copper ring to its leg. The following year he perfectly recognised, by the help of this mark, the Woodcock which had formerly been his captive; it had again visited its old haunts.
During ten months of the year the Woodcock is mute; when the early leaves begin to bud it utters a feeble cry—pitt-pitt-corr!—to attract a mate.
The plumage of the Woodcock is remarkable for the harmony of its shades; it is a happy mixture of brown, russet, grey, black, and white. It is not an unusual thing to meet with Woodcocks entirely of the latter; they are the albinos of their kind. Others are arrayed in an Isabelle-coloured plumage (Fig. 130); but white, with grey or brown mottlings, are their principal peculiarities of plumage.
The Woodcock is very clean in its habits: nothing prevents it pluming and dressing its feathers twice a day. At morning and evening they can be seen bending their course in rapid flight towards rivulets or springs to bore for insects, quench their thirst, and arrange their toilette.
This bird is found in almost all the departments in France, but principally in l'Ain and l'Isère. We need hardly say that they are sought after with an eagerness that no obstacle seems to discourage. One can scarcely imagine the pitch of enthusiasm some of our sportsmen possess for pursuit of the Woodcock. They will walk for ten or twelve hours in the mud, leave shreds of their garments hanging on every bush and bramble they pass, exercise all their ingenuity in manœuvring and cunning, and, as a recompense for all these exertions, not discouraged, perhaps find "the bird flown." This is a short compendium of the results often enjoyed in seeking this woodland denizen.
The chief difficulty in pursuing these birds is, first, to find them, and then to make them flush. Hidden motionless and mute in the thickest bushes, they emit but very little scent to catch the nose of the dog, which ranges about in every direction, disheartened with such laborious and often unprofitable work. After a long trial of patience and perseverance, scratched and torn by thorns and briers, the slightest taint on the air tells the secret—the 342 343 dog draws. As soon as the sportsman sees or knows that his dog is "pointing" at the game, he advances quietly, and judging as well as he can of the locality of the bird, places himself in the best position for firing when it flushes (Fig. 131). If he misses his aim, all he has to do is to follow up, for it is likely enough to drop again only a short distance off. Still the labour to force the game to take wing a second time is not less arduous than heretofore. Both man and dog are often put on the wrong scent by the turns, twists, and circuits of their tracks, and all the other tricks of concealment with which this bird is familiar. If at last the Woodcock succumbs, it will not be till it has thoroughly fatigued its persecutors.
In Brittany, some years ago, Woodcocks were so common that the inhabitants were in the habit of catching them with nets in the following singular way:—Two men went out together at night, one carrying a lantern, the other a small net fastened at the end of a long stick. They proceeded to those parts of the woods where deer had been grazing, which places are always favourite haunts of the Woodcocks on account of their finding worms and insects among their droppings. The rays of light from the lantern were suddenly thrown on the birds while feeding; the latter, dazzled with the brilliancy, allowed themselves to be entangled in the meshes of the net before they thought of flight.
A similar method to the above is practised by the negroes on the Southern plantations of the United States, with this difference—instead of a net, only a club is used for their destruction. Often the slaughter of a successful night amounts to hundreds. The American Woodcock is scarcely as large as the European bird, nor is their colour the same.
The Woodcock constitutes a delicious article of food from its exquisite flavour and piquancy: it in consequence holds the highest rank among game in the eyes of the epicure.
The Snipe much resembles the Woodcock, but is smaller, with longer tarsi. It is also different in its habits. It haunts marshes and fens, feeding on grubs, and sometimes even on aquatic plants. It travels during the night as well as in the day, 344 generally preferring stormy, damp weather for performing its migrations.
The Snipe is found in all latitudes in every part of the globe. Some remain the year round in France and Ireland. They make their nests among reeds in muddy, boggy places, difficult of access to both man and beast, in which they lay four or five eggs. The young ones leave the nest as soon as they are hatched, and are fed by their parents for some time, the want of solidity in their bills not permitting them to bore for their own food.
The Snipe does not live so solitary a life as the Woodcock; it is occasionally seen in wisps or flocks. When flushed they utter a shrill cry, which is easily recognised. They visit us in autumn, coming from the marshes of Poland and Hungary, whither they return again in the spring. The most common species are the Common Snipe (Scolopax gallinago, Fig. 132, 2), the Great Snipe (S. major), the Jack Snipe (S. gallinula, Fig. 132, 1), Sabine Snipe (S. Sabini), and the American variety (S. Wilsonii).
The Common Snipe is no bigger than a Thrush, and has a bill longer in proportion than the Woodcock. It has on the head 345 two longitudinal black stripes; the neck and shoulders are blackish, and the breast white. It is persecuted by some of the small birds of prey, such as the Merlin, the Hobby, and the Kestrel. But, among all its enemies, man is most to be dreaded; he looks upon it as nearly equal to the Woodcock, and for this reason pursues it with the greatest perseverance. It is true that the sportsman pays dearly enough for the pleasure of killing this favourite game; for Snipe-shooting is not only more fatiguing than pursuit of the Woodcock, but is occasionally dangerous. Has not the Snipe-shooter the horrible prospect of rheumatism saddling itself upon him at an age when most persons are still vigorous, to say nothing of the falls he is almost sure to meet with on the perfidious surface of the bogs and marshes traversed, which might perchance even bury him in their muddy depths? Certainly this thought ought to cause reflection; but as rheumatism generally makes its appearance late in life, we seldom worry ourselves about it when young. Besides the drawback of rheumatism, Snipe-shooting is accompanied by innumerable difficulties. Immediately on the bird rising it makes two or three sudden twists, which often baffle even the best shots: proficiency can only be attained by long experience, aided by considerable rapidity and steadiness of hand and eye.
The Great Snipe is about a third larger than that of which we have just been speaking.
The Jack or Deaf Snipe is thus named because it fails to notice the approach of the sportsman, and gets up literally under his feet. This is the smallest of the European species.
Wilson's Snipe (Scolopax Wilsonii) is a native of America. In size it is the same as our Common Snipe. On the prairies of the Western continent it is found in immense numbers. It is, strictly speaking, migratory. The male and female differ slightly in plumage and size, the former having a white breast, while the latter has a brown one. As a table delicacy they cannot be surpassed.
The Godwit (Limosa), Fig. 133, is a beautiful bird, of slender make, with long legs. It is larger than the Woodcock, with a longer beak, this being twice the length of its head, and slender 346 and tapering towards the point, which is rather depressed, and slightly curved upwards.
These birds inhabit the North of Europe, and in the autumn regularly visit France, and the English coast from Cornwall to the north-east extremity of Scotland. They make their nests in meadows near the sea, among the grass and rushes, and lay four eggs, very large in proportion to the size of the bird. Their flesh is much esteemed, and, with the exception of that of the Woodcock and Snipe, is undeniably the best among the group of Waders that frequent our coast.
The male Godwit is always smaller than the female. Two species of this bird are known—the Black-tailed Godwit (Limosa ægocephala), and the Barred-tailed Godwit (Limosa rufa).
The Curlew (Numenius), Fig. 134, is remarkable for the immoderate length of its bill, which is slender, curved, and round from end to end. Its wings are medium-sized, and tail short. Its plumage is a mixture of grey, russet, brown, and white. It derives its name from the plaintive, melancholy cry which it utters when it takes flight.
These birds frequent the sea-coast and the vicinity of marshes, feeding on worms, water-insects, and small mollusks. They 347 plunge their bills into the ground, to a small portion of which they communicate a vibratory movement; the worms, disturbed in their subterranean dwellings, come up to the surface, and are immediately swallowed.
The gait of the Curlews, generally speaking, is grave and measured; but if any one disturbs them previous to taking wing, they begin running with astonishing rapidity. They are capable of a prolonged flight, but do not generally venture far into the interior of the country; it is on the coast they are always most abundant. They live together in numerous flocks, except during their breeding-time, when they isolate themselves in order to build their nests in some dry place among the grass. The female lays four or five eggs. The young ones run about to seek their food as soon as they leave the shell, and receive no attentions from their parents.
The Curlew is of a wild and timid nature. Nevertheless, in Senegal, they have been domesticated; to no great advantage, it is true, as their flesh always retains a very marshy flavour.
Curlews abound all over the globe. They are very common in France, where they arrive in the month of April, leaving again 348 in August, although sometimes they pass the winter on the coast. Of their sojourn in the British Islands the same may be said. A beautiful variety of the Curlew is found in America. In shooting them the great difficulty is to get within range. The sportsman, if well secreted, may occasionally succeed in obtaining a shot at Curlews by imitating their call.
The Ibis has a long bill, curved in the direction of the ground, almost square at its base, and rounded towards the termination; the head and neck are bare. It has four toes; the three front ones are united at the base by a membrane; the whole length of the back toe rests upon the ground.
These birds are inhabitants of the warm regions of Africa, Asia, and America; only one species, the Green Ibis, being found in Europe. They are to be met with in companies of seven or eight together, in moist and marshy grounds, and on the banks of large rivers, where they catch the worms, water-insects, and small mollusks which form the principal part of their food. They also crop young and tender aquatic plants. Their nature being mild and peaceable, they do not keep shifting about with that petulance which characterises some of the Grallæ, but have been observed to remain for hours in the same place engaged in digging into the mud which conceals their small prey. Like nearly all the other birds of this order, they migrate every year, and undertake long journeys from one continent to another. They are monogamous, each pair swearing, as it were, eternal fidelity to one another, and death alone can sever the bonds fortified by affection and habit. They usually build their nests on lofty trees, but sometimes on the ground; the female lays two or three whitish eggs, which hatch in from twenty-five to thirty days.
There are eighteen to twenty species of the Ibis, of which three only merit our attention. These are the Sacred Ibis, the Green Ibis, and the Scarlet Ibis.
The Sacred Ibis (Ibis religiosa) is about the size of a Fowl. Its plumage is white, with black at the extremity of the wings and on the rump. It has enjoyed celebrity from ancient times, on account of the veneration of which it was the object by the 349 Egyptians. They set it up in their temples as a divinity, and allowed it to multiply in their cities to such an extent that, if we can believe Herodotus and Strabo, it actually impeded the traffic. Whoever killed an Ibis, even by accident, at once became the victim of a mad crowd, who stoned him pitilessly; and the dead bird was embalmed with the greatest care, and then placed in earthen pots hermetically sealed, which were ranged in special catacombs. A large number of mummies of the Ibis have been found in the nécropoles of Thebes and Memphis, and several specimens of them are to be seen in the Museum of Natural History at Paris.
The Egyptian worship of the Ibis is a certain and incontestable fact. Less certain, however, is the origin of these honours. Herodotus has given an explanation, obscure enough, it is true, but which, however, was adopted by his successors, and for a long time accepted by our savants.
"The Arabians assure us," says Herodotus, "that the great veneration which the Egyptians render to the Ibis is caused by the gratitude which they feel towards them for ridding the country of winged serpents."
According to tradition, these "winged serpents" came into Egypt from Arabia at the commencement of spring. They always followed the same route, and invariably passed through a certain defile, where the Ibis waited for them and destroyed them. Herodotus adds that, having gone to Arabia to obtain some certain information about these "winged serpents," he saw, lying on the ground near the city of Buto, "an immense quantity of bones and vertebræ unmistakably those of the winged plagues."
Since the time of Herodotus, a great many authors, probably on 350 his authority, have reproduced this fable, and enriched it with variations more or less fanciful. Cicero, Pomponius Mela, Solinus, Ammianus, and Ælian have mentioned it. According to the last writer, the Ibis inspired the serpents with so much dread, that the very sight of its plumage was sufficient to drive them away, and a mere touch killed them at once, or at least stupefied them.
Let it suffice that all these naturalists admit that the Egyptians venerated the Ibis for the service which it rendered by destroying numbers of venomous serpents. In the narrative of Herodotus, as we have seen, the expression "winged serpents" is used for venomous ones. The translation is rather a free one, it must be confessed. Moreover, it is the opinion of M. Bourlet, who has written a memoir on the subject, that by the term "winged serpents" Herodotus intended to describe locusts, innumerable swarms of which were wont to traverse Egypt and the adjacent countries, destroying everything as they pass. This explanation appears to us better than the former, for it is a fact that the Ibis cannot attack serpents, its bill being too weak for such a purpose.
Having quoted M. Bourlet's opinion, we may as well give that of Savigny, the naturalist, whose studies on the subject have been published in the "Histoire Mythologique de l'Ibis."
"Between aridity and contagion, the two scourges which in all ages have been so dreaded by the Egyptians," says the author, "it was soon perceived that when a district was rendered fertile and healthy by pure and fresh water, it was immediately frequented by the Ibis, so that the presence of the one always indicated that of the other, just as if the two were inseparable; they therefore believed that the two had a simultaneous existence, and fancied some supernatural and secret relations existed between them. This idea, being so intimately connected with the phenomena on which their existence depended—I mean the periodical overflowing of their river—was the first motive for their veneration of the Ibis, and became the basis of the homage which ultimately developed into the worship of the bird."
Thus, according to Savigny, the Ibis was venerated by the 351 Egyptians only because it announced to them the annual overflowing of the Nile. This explanation is now generally accepted.
This bird, whose attachment to Egypt was formerly so great that, according to Ælian, it suffered itself to die of hunger when it left the country, strange to say, now is scarcely ever seen there. The cause of this probably is, that the modern Egyptians, treading under foot the ancient faith of their fathers, kill and eat the Ibis as they would any other fowl, without remembering its former rank of divinity. Being deprived of the ancient protection which rendered Egypt so dear to it, the Ibis has almost deserted the ungrateful land of the Pharaohs. Still it occasionally pays brief visits to the Delta at the time of the rise of the Nile; but it soon takes flight into the wilds of Abyssinia, forgotten and unregretted. It is also found in Senegal and at the Cape of Good Hope.
The Green Ibis (I. falcinellus), called by Herodotus the Black Ibis, has black plumage, variegated with green on the upper part. It inhabits the north of Africa and the south of Europe. Like the first-mentioned bird, it was held sacred by the Egyptians.
The Scarlet Ibis (I. ruber) is indigenous to America, and is found principally in Guiana, where it associates in flocks at the mouths of the rivers. Its plumage is of a beautiful vermilion colour, tipped with black at the ends of the wings. It does not, however, wear this brilliant plumage till about two years old. The young are very readily tamed, and their flesh is tolerably well-tasted.
The Cultrirostres (or knife-shaped bill) have a long, strong, and sharp-edged bill. They are generally provided with stout tarsi, and frequent the edges of marshes and banks of rivers. Many of them enjoy the faculty of being able to stand on one leg for hours together. This singular attitude is rendered possible by means of a curious mechanism, which was discovered by Duméril. The tibia, in its junction with the femur, presents a protuberant knot, which forcibly stiffens the ligaments of the knee, forming a kind of catch, similar to the spring of a knife. 352
The principal species of this family are—the Spoonbill (Platalea), Stork (Ciconia), Jabiru (Mycteria, Linn.), Ombrette, Bec-ouvert, Drome, the Boatbills (Cancroma), Heron (Ardea), Crane (Grus), Agami and Caurale, and the Cariama (Palamedea cristata).
The Spoonbill is remarkable for the singular form of its bill, which is about four times the length of the head, straight, and flexible; the upper mandible, about an inch and a quarter broad at the base, gradually narrows to three-quarters, and again increases to two inches at the point, causing a resemblance to a spoon, from which it takes its name. It uses this bill for dipping into the mud and water, whence it extracts worms and small fish, on which it principally feeds. It also eats water-insects, which it catches by placing its bill half open on the surface of the water, permitting them thus to float on to the lower mandible. It lives in small companies, and frequents places near the sea-shore. It is easily tamed.
There are two species of them: the White Spoonbill, which has a tuft on the back of its neck, and is found in most parts of Europe—it is, however, seldom met with in France, and then only in the south; and the Rose-coloured Spoonbill, a native of South 353 America, the plumage of which presents the most beautiful tints.
The Stork (Ciconia) has a long and straight bill, wide at the base, pointed, and sharp-edged; legs long and slender; tibia bare for half its length; tarsi long, compressed, reticulated; hind toe short, slightly elevated, and inserted rather high, but resting upon the ground; the tail is short. They are found in nearly all parts of the world. Some species migrate with great regularity, being admirably constructed for travelling considerable distances; for, although their bulk seems great, their weight is comparatively small, as most of their bones are hollow. In their migratory journeys they fly in continuous or angular lines, and chiefly by night.
Storks live in moist and swampy places by the side of pools and rivers. They feed principally on reptiles, batrachians, and fishes; but they also devour the smaller birds and mammalia, mollusks, worms, and insects; among the latter, even bees become their victims, nor do they disdain carrion and other impurities. Their manner is slow and grave, and they are rarely seen to run. They have wonderful powers of flight: on the wing they resemble crosses, from their manner of carrying the head and neck. They have no voice, and the only noise they make is a cracking, which results from one mandible of the bill striking against the other, and which expresses either anger or love; it is sometimes very loud, and, under favourable circumstances, may be heard as much as a league away. They lay from two to four eggs, their fecundity increasing in an inverse ratio to their size. The duration of their life is from fifteen to twenty years.
There are several species of Storks, the most important being the White Stork (Ciconia alba). It measures about forty inches in height; length to end of tail, forty-two inches; wings, extended, seventy-six inches; its plumage is white; the wings are fringed with black. This is the species best known in Europe; it is chiefly met with in Holland and Germany. In France, Alsatia is chosen as a residence by nearly all those that visit that country. It is so rarely seen in England, that there it has become almost a matter of legend. It is very common in the warm and temperate parts of Asia. Leaving France every year in the 354 month of August in order to visit Africa, it returns in the following spring. This migration is not caused by temperature, as the Stork can bear the most bitter cold. No, it is a mere question of sustenance; for feeding, as it does, principally upon reptiles which remain in a complete state of torpor during our winters, it is naturally compelled to seek its food elsewhere.
The Stork is of a mild nature, and is easily tamed. As it destroys a host of noxious creatures, it has become a useful helper to man, who is not ungrateful, for he has in all ages given it succour and protection. In ancient Egypt it was venerated on the same score as the Ibis; in Thessaly there was a law which condemned to death any one killing these birds. Even at the present day the Germans and Dutch esteem it a happy omen when the Stork chooses their house as its home. They go so far as to furnish it with the means of doing this, by placing on the roof a box or a large wheel; this forms the framework of the nest, which the bird then finishes according to its fancy with reeds, grass, and feathers.
When the Stork has attached itself to a place, and is kindly treated, it sometimes loses the habit of migrating. It cannot, however, quite get rid of a certain agitation when the season for departure comes: occasions have been known where it yielded to the appeals of its wild companions and to the desire for progeny (for in captivity it is always barren), and was allured away to join the band of travellers. But this separation is only temporary; the next year the truant returns to the same house, and again takes possession of its domicile with many a flapping of wings to testify its joy. It exhibits great pleasure in renewing acquaintance with the denizens of the house, and is not long in placing itself on a footing of familiarity with them. It frolics with the children, caresses the parents, plagues the dogs and the cats—in a word, manifests a gaiety and susceptibility of affection which one would hardly expect to find in a bird generally so dull and taciturn. It presents itself at the family meals, and takes its share of them. If its master tills the ground, it follows him step by step, and devours the worms which are turned up by the spade or the plough. 355
The Stork may certainly be set up as a model for all mothers: its love for its young ones sometimes even approaches heroism. We will give two touching instances.
In 1536 a fire broke out in the city of Delft, in Holland. A Stork, whose nest was placed on one of the burning buildings, made at first every effort to save its progeny. Finally, seeing its inability to assist them, it suffered itself to be burnt with its loved ones rather than abandon them.
In 1820, at another fire at Kelbra, in Russia, some Storks, when threatened by the flames, succeeded in saving their nest and young ones by sprinkling them with water, which they brought in their beaks. This last fact proves to what an extent intelligence may be excited under the influence of maternal love.
The Stork is not only a good mother, but she is also an excellent wife. The attachment which these birds show for each other when they are once paired has long back procured for them a high reputation for conjugal fidelity. Thus, in the Vorarlberg (Tyrol), a male Stork was known to have refused to migrate, passing several winters by the side of his mate, which, in consequence of a wound in her wing, was unable to fly.
We must, however, add that some lady Storks are by no means slow in consoling themselves for the loss of husbands who ought to be the subjects of eternal regret. A few tears, as a matter of form, and their grief ends! Sprungli notes the case of one widowed Stork who contracted new bonds after two days' mourning. Another gave evidence of the most guilty perversity. 356 The lady began by betraying the confidence of him with whom she had united her destinies; his presence had evidently become insupportable to her, and she finally killed him with the help of her accomplice.
These errors of the female render the high morality of the male more conspicuous. Witness the following story, related by Neander:—
A number of Storks had taken up their abode in the market-town of Tangen, in Bavaria. Perfect harmony reigned in every family, and their lives were passed in happiness and freedom. Unfortunately, a female, who had been up to that time the most correct of Storks, allowed herself to be led away by the idle gallantries of a young male; this took place in the absence of her mate, who was engaged in seeking food for his family. This guilty liaison continued until one day the male, returning unexpectedly, became convinced of her infidelity. He did not, however, venture to take the law into his own hands; he was reluctant to dip his bill into the blood of her he had once loved so fondly. He arraigned her before a tribunal composed of all the birds at the time assembled for their autumnal migration. Having stated the facts, he demanded the severest judgment of the court against the accused. The ungrateful spouse was condemned to death by unanimous consent, and was immediately torn in pieces. As to the male bird, although now avenged, he departed to bury his sorrows in the recesses of some desert, and the place which once knew him afterwards knew him no more.
The Storks of the Levant manifest a still greater susceptibility. The inhabitants of Smyrna, who know how far the males carry their feelings of conjugal honour, make these birds the subjects of rather a cruel amusement. They divert themselves by placing Hen's eggs in the nest of the Stork. At the sight of this unusual production the male allows a terrible suspicion to gnaw his heart. By the help of his imagination, he soon persuades himself that his mate has betrayed him; in spite of the protestations of the poor thing, he delivers her over to the other Storks, who are drawn together by his cries, and the innocent and unfortunate victim is pecked to pieces. 357
Besides the numerous virtues that we have just stated—paternal love, conjugal fidelity, chastity, and gratitude—the ancients attributed to them (among birds) the monopoly of filial piety. They believed that these birds maintained and nourished their parents in their old age, and devoted themselves to alleviating the trials of the last years of their lives with the most tender care. Hence was derived the name of the "Pelargonian Law" (from the Greek πελαργος, a Crane), the name given by the Greeks to the law which compelled children to maintain their parents when old age had rendered them incapable of working. This last feature in its character has not a little contributed to the universal celebrity of the Stork.
The flesh of the Stork forms but a poor article of food; it is, therefore, rather difficult to see why the sportsmen in our country persist in shooting at it every time that they get a chance. The reprehensible mania which our French Nimrods possess of indiscriminately massacring everything which shows itself within reach of their guns is a disgrace to those who practise it, and an injury to the community at large. The result is that the Stork, meeting with nothing but ill-treatment in return for its loyal and useful services, is gradually retiring from France, and before long will have completely abandoned it.
The Black Stork (Ciconia nigra) is rather smaller than the one above named; it is a native of Eastern Europe, and is rarely seen in France. It feeds almost exclusively on fish, which it catches with much skill. It is very shy, and avoids the society of man; it builds its nest in trees.
The Argala, or Marabout, also called the Adjutant Bird, or Gigantic Crane, is characterised by its very strong and large bill, and the bareness of its neck, the lower part of which is provided with a pouch somewhat resembling a large sausage; but, according to Temminck, there is a notable difference between the African Marabout and the African Argala, the characteristic mark of the latter frequently hanging down a foot, while it is much shorter in the Marabout.
These birds are inhabitants of India; they feed on reptiles and all kinds of filth, and this fact has been the means of securing for 358 them the good-will of the people. In the large cities of Hindostan they are as tame as dogs, and clear the streets of every kind of rubbish which litters them. At meal-times they never fail drawing themselves up in line in front of the barracks, to eat the refuse thrown to them by the soldiers: their gluttony is so great that they will swallow enormous bones. At Calcutta and Chandernagore they are protected by the law, which inflicts a fine of ten guineas on any one killing a Marabout.
The long white feathers, celebrated for their delicacy and airiness, which are used in the adornment of ladies' bonnets, and known in commerce by the name of Marabout feathers, come from this bird, and grow under its wings. Consequently, in spite of 359 their ugliness, a good many Marabouts are reared in a domestic state in order that these lovely feathers, on which our European fair ones place so much value, may be plucked from them at the proper seasons.
There are several other species which are allied to the Storks, and are only distinguished from them by a slightly different form of the bill. We will confine ourselves to merely naming them and pointing out the localities they inhabit. They are as follows:—The Jabiru (Fig. 139), which is a native of South America; the Ombrette, which is found in Senegal; the Bec-ouvert, which inhabits India and Africa (Senegal and Caffraria); the Drome, 360 which is met with on the shores of the Black Sea and Senegal; and finally, the Tantalus, which lives in the warm regions of both the New and Old World.
Whoever has once set eyes on the Boatbill or Savacou (Fig. 140) will never forget the bird, or confound it with any other. What, it will be asked, is there so characteristic about it? Nothing else but its bill, which certainly is the most singular implement one can well imagine. Fancy two long and wide spoons, with their hollow sides placed one against the other, the end of the upper spoon being furnished with two sharp teeth, and we shall have some idea of this extraordinary storehouse, as it may be called, for the proprietor can easily stuff into it provisions for a whole day. If we add to this that the Savacou possesses a beautiful black crest which hangs down behind its head, that it is about the size of a 361 Fowl, also that it has short wings, and rests its four toes firmly on the ground, we shall then have a pretty exact portrait of our subject. This bird inhabits the savannahs of Central America, and occasionally the southern portion of the United States, frequenting the banks of rivers, where it feeds on fish, mollusks, and sometimes crabs. It makes its nest in the thick underbrush.
The Herons (Ardea), which form a genus of birds of the order of Cultrirostres, have the bill long, pointed, opening widely, and very strong; their legs are in part bare of feathers; toes long, and furnished with sharp claws, not excepting the back toe, the whole length of which rests upon the ground; the neck is long and slender. Further, the back of the head is adorned with a tuft of long feathers, which fall over its shoulders like a plume, whilst those in front, which are narrow and pendent, resemble a kind of beard at the bottom of the neck.
These birds lead a semi-nocturnal life, and frequent the margins of lakes, marshes, and rivers, where they feed on reptiles, frogs, and fish. They are generally of a shy nature, and live in solitude in the most unfrequented portions of extensive woodlands. When they want to seek their prey, they go into the water until it reaches half-way up their legs, and with the neck doubled down over the breast, and the head buried between the shoulders, they sometimes remain for hours together immovable as statues. If any fish glides along within reach of them, they suddenly stretch out their necks, as if impelled by a spring, and, with a sharp movement of the bill, impale the unfortunate victim. When their fishing is not very productive they dig into the mud with their feet, to turn out the frogs and other reptiles that are concealed in it. If compelled by hunger, they will attack rats, wood and field mice, and if further pressed they show no repugnance to carrion. They can, however, endure abstinence for a considerable time.
Most of the Herons are endowed with great powers of flight. When compelled by unusually severe weather, they occasionally migrate, the young and the old travelling separately. Nevertheless, as they can accommodate themselves to almost any temperature, 362 some species are stationary, and they are to be met with all the year round in countries the most dissimilar.
The principal species of Herons are the Ash-coloured or Common Heron (Fig. 141), the Purple Heron, the White Heron, the Bittern, the Night Heron, and the Crab-eater.
Every one knows the Grey Heron (Ardea cinerea), at least by reputation, if only from La Fontaine's verse:—
Its height is about forty inches, and it is found in nearly all parts of the globe. It is the most common of the French Herons, and the only one which joins its fellows during the breeding season, in order to build their nests and sit on their eggs, and rear their young in company. The place appropriated for this assemblage is generally a clump of lofty trees in the neighbourhood of some large lake or river. On the summits of these trees, or in the angles formed by the branches, the Herons build their nests, which are of very simple construction—a few boughs interwoven together with smaller twigs, and without any additions, such as moss, grass, &c., with which smaller birds love to line their dwellings. In these nests the females lay three or four eggs, and the males share with them the cares of incubation. After the eggs are hatched, the male assists in the nourishment of the young family. Frequently he disgorges into the bills of his young ones the frogs and small fry he has just swallowed; sometimes he divides among them a large fish which he brings from the adjacent lake or the more distant sea-shore. Occasionally they undertake journeys in order to insure abundance for their progeny, and their excursions often extend over a very considerable tract of country.
When the young Herons are able to fly, they leave the nest and provide for their own wants.
But the time for migration has arrived. About the beginning of August, and always at the same date, the colony, then amounting to five or six hundred individuals, range themselves in order and quit the heronry. The following year they return thither, and their arrival, like their departure, takes place on a regular 363 day. It is remarked that the number of couples is always nearly the same as that of the nests, so that each couple may readily find a resting-place. The new generation must, therefore, have gone to found a fresh colony in some other locality.
Heronries are becoming more and more rare. M. Toussenet states that he has met with only one in all France, that at Ecury (Marne), between Epernay and Châlons. They are not uncommon in England, where many ancient families connect the heronry with their ancestral grandeur. Lord Warwick's heronry, on the classic Avon, still maintains seventy or eighty pairs of the noble birds.
The Grey Heron has enemies in the Eagle, the Falcon, and the Crows. The latter combine to steal its eggs; the former aim at the Heron itself, its flesh being much to their taste. When the Heron finds itself pursued by a bird of prey, it immediately disencumbers itself of all unnecessary ballast, and then endeavours to get the uppermost in flying; this plan is nearly its only means of safety. Occasionally it succeeds, for the Heron is able to attain immense altitudes. If it is close pressed, it makes an admirable use of its bill as a means of defence, and has been known to impale its adversary. Its usual tactics are, to wait for its enemy, lance in rest, and to allow the latter to pierce himself through, merely by his own impetuosity. If it has a chance to dart its bill into the eye of its foe, it does not neglect so good an opportunity of utilising its small endowments. This is, in fact, a private lunge, a coup de grâce, and many a dog, hunting among the reeds, has felt the poignancy of this offensive weapon. We must, however, allow that the Heron is not always so fortunate, and that oftener than not he becomes a prey to his eager adversaries—the Eagle and the Falcon.
The magnificent powers of flight possessed by the Heron, and his clever devices in defending himself, gave rise, in days gone by, to the very special regard with which he was honoured by kings and princes, who hunted him with Falcons trained to the sport. The poor Heron was doubtless not very gratified for these marks of high esteem, and it is probable that, if he could be consulted at the present day, he would bless the happy obscurity in which he 364 is now allowed to vegetate. "It costs too much to shine in the world," is the moral La Fontaine puts into the mouth of his Heron.
Although its flavour is certainly as disagreeable as possible, the flesh of the Heron was in the old time reckoned as a "royal dish," and was only served upon the tables of the great and powerful of the earth. In order to procure this supposed delicacy more easily, the idea arose of artificially arranging a certain part of the forest so as to attract the unhappy birds into a retreat which should realise all the characteristics of the natural heronry. The birds here enjoyed all the comforts of life up to the moment when they were ruthlessly torn from them at the will and pleasure of their lord. We must add that they adopted the plan of taking from them their progeny to assist the royal treasury; for, as Pierre Belon tells us, "they were in the habit of trading largely in the young ones, which brought considerable sums of money." Francis I. caused heronries to be established at Fontainebleau, which, as connoisseurs tell us, were everything that could be wished.
The Heron is quite susceptible of training when it is caught young; but it must always be little else than a bird of ornament, as the service it can render amounts to little or nothing. When adult at the time of capture it is altogether intractable, entirely refusing food, and dying at the end of a few days.
The Purple Heron (Ardea purpurea) has the same habits as the one just spoken of, but it is a little smaller. It owes its name to the colour of the numerous spots which adorn its livery. It is rarely met with in France, but is pretty common at the mouths of the Danube and Volga, and on the margins of some of the lakes in Tartary.
The White Heron (Egretta alba) is remarkable for its plumage, which is entirely of a pure white. Two varieties of it are known—the larger, generally called the Great Egret, is about the size of the Ashy Heron; it is common in Eastern Europe, in the North of Africa and America, and in the Malay Archipelago. The smaller kind is known by the name of the Garzette Heron, or the Little Egret, and is no bigger than a Crow; it inhabits 365 the confines of Asia and Eastern Europe, and regularly visits the South of France.
These two species are adorned, during the breeding season, with fine and silky feathers, which spring from the shoulders, and, spreading out over the back, fall on each side of the tail in elegant plumes. These are the feathers with which European ladies are so fond of adorning themselves, and from them the birds have derived their name.
Northern Africa presents us with a beautiful White Heron, about the size of a Pigeon, the functions of which are extremely interesting; it is called the Ox-keeper. In Morocco this bird is very common. It is in the habit of accompanying the oxen into the fields, and takes the task of relieving the latter from the numerous flies and insects with which they are annoyed. In France it is met with only at the mouth of the Rhône. 366
The Bittern (Botaurus) has both the neck and legs shorter than those of the Grey Heron; its plumage is of a rich reddish yellow, boldly variegated with dark markings. Districts intersected by marshes are the chief places of its resort; in these it keeps itself hidden all day long among the reeds, motionless and silent. Here, too, it makes its nest, almost on the ground, and close to the water. It does not leave its hiding-place until the evening, and then will fly up to so great a height as to be lost to view. Its call to its mate is peculiar; it resembles the bellowing of a bull, and can be heard more than half a league away. For this reason the ancients called it Bos taurus—whence, by corruption, comes the French Butor.
The Bittern is a very courageous bird; it will defend itself energetically against any bird of prey, against dogs, and even man. It is found all over Europe. Four British species are described—B. stellaris, B. lentiginosus, B. minutus, and B. comatus.
The Crane (Grus), which forms a genus among the Cultrirostres, is characterised by a bill much longer than the head, stout, straight, tapering, compressed, and pointed, but always slightly cleft; feet long; tibia bare for a fourth of its length, covered with hexagonal scales; toes, four; back toe short, which does not reach the ground; wings long and pointed. The Cranes are essentially migratory birds, and possess wonderful requisites; for, in addition to prolonged powers of flight, they enjoy the valuable faculty of being able to endure total abstinence from food for several days—a faculty which, we may remark, is common to most of the Wader tribe, though in a less degree.
There are three species described—the Ash-coloured Crane, the Crested Crane, and the Demoiselle Crane.
The Ash-coloured Crane (Grus cinerea), Fig. 142, is a fine bird, attaining nearly five feet in height. With the exception of the neck, which is black, all the rest of its body is of a uniform ashy-grey colour. The carriage of the bird is noble and graceful, and the feathers on its rump, which rise up in undulating clusters, add much to its elegance.
These Cranes are periodical visitors to France; they arrive in 367 Europe in the month of April or May, passing the fine weather in more northern countries. Towards the middle of October, on the arrival of the first cold weather, they leave us, in order to winter in Egypt, Abyssinia, or even Southern Asia. They travel in flocks, numbering sometimes as many as three or four hundred birds; generally they arrange themselves in two lines, so as to form an isosceles triangle, or a sort of wedge with the point in front—the most convenient formation for cleaving the air with the least amount of fatigue. From time immemorial people have been fond of saying that these birds intrust the care of their guidance to a chief, who, after having led the way for a certain time, and becoming wearied, surrenders his charge to one of his companions and passes to the rear of the band, where, like a new Cincinnatus, he resumes the position of a simple citizen. The fact is, that the leader of the two files changes perhaps ten times in a minute, and the apex of the angle is occupied in succession by every Crane in the flock within a very short space of time.
Cranes almost always travel at night, and alight down on the ground during daytime to seek their sustenance. Sometimes, however, they do not stop, and continue to push on through space, giving utterance to startling cries, which probably are intended as a rallying summons to those of the band which seem tempted to linger on their journey. When they perceive a bird of prey, or have to contend against a tempest, they abandon their usual formation, and collect in a circular mass, so as better to resist the enemy. 368
Cranes frequent large plains intersected with marshes and water-courses. They feed on fish, reptiles, frogs, mollusks, worms, insects, and even small mammals. Some kinds of grain have also attractions for them, and they may not unfrequently be seen invading the newly-sown fields to devour the seed which the farmer has just committed to the soil.
When the breeding season arrives, they break up their social compact, and pair off for the purposes of reproduction and attending to the rearing of their young.
Their nests are but roughly constructed, and are placed on any little piece of rising ground in the midst of the marshes; in them they lay usually two eggs, the male sharing with the female the cares of incubation. Although these birds are ordinarily so timid, and are alarmed at the least appearance of danger, yet, when they have their young ones to defend, they become really courageous. In this case they do not shrink from attacking man.
The Crane ought to have been the emblem of vigilance. When the flock go to sleep, with their heads hidden under their wings, one of their number is specially charged with the duty of watching over their common safety, and of giving alarm on the approach of danger.
When caught young they are easily tamed, and in a very short time will manifest considerable familiarity with their keeper. They are, therefore, a good deal sought after in some countries, both on account of their graceful shape, and also for the sake of the vigilance which they exercise round about their home.
These birds were well known in ancient times; Homer, Herodotus, Aristotle, Plutarch, Ælian, Pliny, and Strabo have noticed them and their migrations. Unfortunately, not content with correct observations, they have given credence to some most ridiculous fables, invented in Greece and Egypt, the classic and fertile lands of the marvellous. Thus, according to the Egyptian story, the Cranes made an expedition to the sources of the Nile to fight against the Pygmies, who were, as Aristotle says, "a race of little men, mounted on little horses, who dwelt 369 in caves." According to Pliny, these little men were armed with arrows, and mounted on rams; they abode in the mountains of India, and came down every spring to wage war against the Cranes, whose sole object was to exterminate the Pygmies. The Roman naturalist fancies that they succeeded in this destructive aim, for the town of Gerania, which even in his time was ruined and deserted, was formerly, he asserts, inhabited by a race of Pygmies, who were driven out by the Cranes. In the views of modern commentators, these Pygmies were nothing but monkeys, which assemble in large troops in the forests of Africa and India, and always manifest hostility to birds.
The Greeks have also invented two stories about Cranes, which are certainly very ingenious, but result from the error of attributing too much importance to trifles. They say Cranes carry a pebble in their mouths when they cross Mount Taurus, so that they are compelled to keep mute; they thus avoid exciting the attention of the Eagles inhabiting those districts, which birds are much disposed to do them mischief. In the same way, the Crane which is placed as sentinel to watch over his sleeping companions is bound to stand on one leg, and carry a stone in the other claw, so that if he allows himself to be overtaken by slumber, the fall of the pebble would wake him up. It was, as we are aware, the expedient of the youthful Aristotle to hold an iron ball suspended over a metal basin in order to wake himself if he succumbed to sleep. We shall, I think, ascribe too much ingenuity to the Crane in imputing to it an action of Aristotle's.
The members of this interesting feathered tribe were said to possess certain virtues. The thigh bone of a Crane imparted to him who possessed it remarkable vigour and elasticity of limb. Its brain also was a kind of love-philtre; it transformed the ugliest man into a perfect Adonis, and won for him the favour of the fair.
It is, moreover, to the Crane that the Greeks are indebted for one of their favourite dances. Be it understood that we are now returning to plain matter of fact. The games and dances which Cranes indulge in amongst themselves are not mere idle stories; observers of our own day, well worthy of credit, have proved their 370 complete authenticity. It is certainly true that these birds form groups in various fashions, advance one towards another, make a kind of salutation, adopt the strangest postures—in a word, indulge in pantomimes both burlesque and amusing. This is, we must confess, a curious element in their character, and has been made the most of by the Chinese, who are in the habit of teaching Cranes to dance according to all the rules of art.
The ancients set a high value on the flesh of the Crane, which is, nevertheless, anything but good. The Greeks especially showed a great fondness for it; they used to fatten these birds after having put out their eyes or sewed up their eyelids; this cruelty being necessary, according to their idea, to cause a proper degree of plumpness.
In the fine old days of hawking, the Crane, as well as the Heron, enjoyed the esteem of princes. Even in the present day, in Japan, it is reserved for the sport of the Taïcoun (king), and the common people treat it with all the respect that is consequently its due.
We should certainly fall short in our traditionary lore if we failed to relate the far-famed story of the Cranes of Ibycus. Ibycus of Rhegium was a lyric poet, who enjoyed some reputation in his day. On one occasion, when he was proceeding to the Olympic Games in order to contend for the poet's prize, he lost his way in a forest, and fell into the hands of two malefactors, who cruelly murdered him. Just as he was dying he cast his eyes towards heaven, and perceiving a flock of Cranes passing over, he cried out, "O ye bird-travellers, become the avengers of Ibycus!" The next day the two robbers were quietly taking a part in the Olympic contests, when the news of the murder, which arrived during the day, excited some sorrowful emotion. All of a sudden a flight of Cranes passed over the arena, uttering loud cries. "Do you see the Cranes of Ibycus?" said one of the murderers to his comrade in a humorous tone. This remark, being overheard by some persons standing by, and commented upon by a thousand lips, became the ruin of the two scoundrels. At once arrested and pressed with questions, they were compelled to confess their crime, and were immediately put to death. Thus was fulfilled the dying invocation of Ibycus. 371
The Demoiselle Crane (Grus virgo) is remarkable for two beautiful clusters of white feathers, which are suspended behind its head, and for a black, pendent tuft with which nature has adorned its breast. Its size is about the same as that of the species just described, and its shape is still more elegant. It also enjoys in a higher degree the gift of the mimic art. Its slightest movements have an air of affectation and mannerism, as if it desired, at any rate, to attract the attention of the spectator; hence, in French, the name of Demoiselle has been given to it. It is found in Turkey and Southern Russia, in Northern Africa, and in some parts of Asia adjacent to the latter region.
The Crested Crane (Grus pavonina), or Royal Bird, has the top of its head adorned with a tuft of feathers, which it has the power of spreading out like a fan, so as to form quite a resplendent ornament. About the same size as the two sister-birds, it is slender and graceful. Its voice is very loud. It seeks the acquaintance of man, and readily grows familiar with him. Its chief locations are the eastern and northern coasts of Africa, and also some of the isles in the Mediterranean: according to the ancients, it was formerly common in the Balearic Islands.
The Agami, or Hooping Crane (Psophia crepitans, Latham), has a strong and tapering bill, shorter than the head; long tarsi; and medium-sized toes, the back toe touching the ground at the extremity only. Its wings are short, and, in consequence, it flies with difficulty; but, to make up for this deficiency, it can run very swiftly. This bird is but little bigger than a domestic Fowl. It is in the habit of uttering at intervals a piercing cry, which seems as if it did not proceed from the bird itself; this cry has procured for it the name 372 of the Trumpet Bird, and has caused some to ascribe to it the talent of ventriloquism. It makes its nest on the ground, in a hole scratched out at the root of a tree, and feeds on grasses, seeds, and small insects. Shyness is not one of its qualities, and it will submit to captivity without repugnance; it forms an attachment to its master, and solicits his caresses, just like a pet dog. The latter comparison is all the more just, as the bird renders very much the same service to man as the animal. This bird is intrusted with the care of the flocks out of doors, and in the evening brings them back to the farm, where his activity finds plenty of scope in the poultry-yard.
In its wild state the Agami inhabits the forests of South America. Its flesh is agreeable in flavour, and is often eaten. It is easily domesticated, and attaches itself to man, following its master about.
The Caurale (Fig. 145), which forms a genus in the order we are 373 now considering, is a bird about the size of the Partridge, with a large and fan-like tail. Its brilliant hues have obtained for it in Guinea the name of the Little Peacock, or Sun Bird. It is very wild in its nature.
The birds which belong to the order Pressirostræ are characterised by a middling-sized bill—not, however, devoid of strength—and a back toe which is altogether rudimentary; indeed, in some species entirely wanting. They are mostly vermivorous; some, however, are granivorous or herbivorous. In this order a number of rather dissimilar birds have been reckoned, some of which belong decidedly to the Wader tribe, whilst others, by their general habits, are more allied to the Gallinaceæ. Among them are the Cariama (Fig. 146), the Oyster-catcher, the Yellow-leg, the Stone Plover, the Lapwing, the Plover, and the Bustard.
The Oyster-catchers (Hæmatopus) are characterised by a long, pointed, and powerful bill, which they use like a pair of pincers for opening oysters, mussels, and other shell-fish left on the shore by the receding tide, with the sole purpose of devouring their contents. Few things are more interesting than to see them 374 hovering over the retiring water, alternately advancing and retreating with the waves. As their toes are united at the base by a web or membrane, they enjoy the faculty of resting on the water, although they do not actually swim. They utilise this power in allowing themselves, every now and then, to be carried on the waves to some distance from the shore. They fly well, and can run with the greatest ease. Numerous flocks of them are found on almost every sea-coast on the globe, making the neighbourhood ring with their shrill cries.
In the breeding season they pair off; the hen birds lay from two to four eggs, either in holes carelessly scratched out on the strand or in clefts of the rocks, or sometimes in marshy meadows some distance from the shore. 375
They assemble in considerable flocks for the purpose of migration—if this term may be held applicable to the short journeys which they annually undertake. They ought rather to be called pleasant little jaunts—inspections, as it were, of their domains; something like the circuit of his department made by a prefect, or the progress of a sovereign through his country.
There are three or four species of the Oyster-catcher, only one of which is a native of Europe. The plumage of the latter is white and black, which, joined to its noisy habits, has obtained 376 for it the nickname of the Sea Magpie. Its bill and feet are of a beautiful red colour; hence the name of Hæmatopus (feet the colour of blood) was given by Linnæus to the whole genus, when the other varieties of it were yet unknown. It is found at all seasons on most of our coasts. As an article of game it is not all one could wish.
The Runners (Cursorius) have slender and pointed bills, slightly bent at the end; long tarsi; no back toe; wings much pointed; its plumage is of a dove colour, and it is about eighteen inches in height. As its name implies, it runs with surprising rapidity. It is a native of Asia and the north of Africa, and only casually makes its appearance in Europe. Nothing is known of its habits.
The Lapwings (Vanellus) have the bill enlarged on the upper side, two-thirds of its length being filled up by the nasal channels; its back toe is excessively short, and wings pointed. When flying, they make a noise which is not unlike that of corn falling back on the winnowing-fan; hence their French name, Vanneau.
These birds are essentially migratory, and come down from the high northern latitudes in large flocks at the beginning of autumn, again returning thither in spring. They frequent marshes and the margins of lakes; in fact, all moist, soft districts which abound in earth-worms, insects, slugs, &c. They may often be seen settling down on fields recently ploughed, where they can find an ample supply of worms. They are in the habit of employing a rather ingenious process to make their victims emerge from the earth. They strike the ground with their feet, and thus give the surface a slight shock, which the worm is tempted to attribute to the proximity of a mole; and consequently it hastens to the surface to escape its underground enemy, when it is immediately snapped up by the bird.
The Lapwing is a model of cleanliness. After it has been feeding on the ground for two or three hours, it washes its bill and feet; it repeats these ablutions several times in the day. In this respect the most rigid Mahommedan could scarcely find fault with it.
Lapwings live together in communities, except in the breeding season, when they separate into pairs, to devote themselves to 377 hatching and rearing their young. The hen lays three or four eggs in the most simple nest that can be imagined, placed in an exposed position on any little rising ground in the marshes. These eggs are, it is said, of an exquisite flavour, and in some countries, especially Holland, a large trade is done in them.
The flesh of the Lapwing is only good eating during certain months of the year. About All Saints' Day these birds acquire their finest condition, when in some parts of France they are in great demand. In the spring, as food, they are very indifferent, easily explaining why the Church has allowed them to be eaten during Lent, for at that period assuredly no food could be more maigre. There is an old saying which celebrates, and also exaggerates, the culinary virtues of the Lapwing and its brother bird, the Plover: "He who has never eaten either the Plover or the Lapwing does not know what game is."
The Lapwing might be ranked amongst the most useful auxiliaries of man; it destroys a prodigious quantity of worms, caterpillars, and noxious insects. After hearing this the reader might, perhaps, imagine that this bird has found aid and protection 378 from mankind. Nothing of the sort; it is killed wherever and as often as possible; besides this, means are discovered to set a limit upon its multiplication by stealing away its eggs. We do not seem to perceive that this joyous, lively, and graceful bird longs to conclude a treaty of friendship with mankind. When will man make up his mind to understand his true interests?
There are in Europe two species of this genus—the Crested Lapwing and the Swiss Lapwing, or Squatarole.
The Crested Lapwing (Vanellus cristatus), Fig. 149, is about the size of a Pigeon; its belly is white, and its back black, with a metallic lustre. It is furnished with a crest, which coquettishly adorns the back of its head. It is tolerably abundant in France, but seems more especially partial to Holland. The Swiss Lapwing is distinguished from the last by a lighter-coloured plumage, and by the absence of the crest.
The Plovers (Pluvialis) have a bill closely resembling that of the Lapwing, and differ from it chiefly in the latter having a back toe, which is absent altogether in the Plovers. They are, however, connected by several ties of kindred. Like the Lapwing, they live in moist places and in numerous flocks; like them, they feed on worms, which they catch much in the same way; like them, too, they make frequent ablutions; finally, they are always close neighbours, and unite in migration. But they do not follow out the resemblance with the Lapwings so far as to imitate them in behaving as good fathers of families, and in living as good citizens with one wife chosen once for all. Plovers understand life in quite another fashion; they have other aspirations and other desires; fidelity in love is not a quality which suits them, and they practise polygamy on the very largest scale.
One might well fancy that a bird of such low morality would not be easily affected by the misfortunes of its fellows, and that it would be endowed with no feelings but those of utter selfishness. But nothing of the sort. If you knock down a Plover flying in company with others, you may notice the whole flock coming back to it to render the disabled one all the help they can; and if you are not too much of a novice, you will find no great difficulty 379 in turning this circumstance to your profit by filling your game-bag.
The Plover migrates from the North of Europe to Africa, and vice versâ; it thus visits France twice a year, in spring and autumn. It is their appearance at these usually rainy seasons which has given them the name they bear. There are five principal species—the Great Land Plover, the Dotterel, the Ringed Dotterel, the Kentish Plover, and the Golden Plover.
The Great Land Plover (Oidicnemus Bellonii, Fleming) is about the size of a Crow; it is very uncommon, very active, and very suspicious in its nature. The only chance of shooting it is in the evening, at the moment when it comes to wash itself on the edges of lakes and rivers. Its flesh is not much valued.
The Dotterel (Pluvialis morinellus) is a little larger than a Blackbird. It visits us in March and September, and numerous flocks of these birds frequent the vast plains of the beautiful country of France. This is the bird which persists in sacrificing itself to the sportsman's gun when its companion has fallen a victim before the murderous weapon. It also shows the simplicity of believing that drunken people must be animated with the kindest feelings towards it; so much so, that it is only requisite to exhibit the outward signs of bacchanalian excitement, and the birds will be filled with a sense of false security, so that you may approach within a few yards of them.
The Dotterel has been the means of founding the reputation of the Pâté de Chartres: the bird's own personal experience must long ago have convinced it how heavy the burden of renown sometimes proves. They have, in fact, found themselves so much relished, that they have been tracked and hemmed in on all sides by eager pie-makers. The only chance for the poor creature is to seek safety in flight, and abandon a country where it is decidedly too much loved. Without either regret or envy it must have seen that Larks and Quails have usurped its place in popular favour for filling pâtés.
The Ringed Dotterel (Charadrius hiaticula), Fig. 150, is about half the size of the last bird. It is distinguished by its black collar, and also by its extraordinarily brilliant and gold-coloured eyes. In former days this bird had the credit of being able to 380 cure the jaundice. All that was necessary was for the sick person to look fixedly at the bird's eyes, with a firm faith in the success of the experiment; under these conditions the bird was obliging enough to relieve him of his malady. This superstitious idea has departed to join all the rest of the medical opinions of the middle ages.
The Kentish Plover (Charadrius cantianus, Latham) is thus named on account of its collar being divided into two parts; it is rather smaller than the last-named bird, and is found in Europe and Asia.
The Golden Plover (Pluvialis aurea), Fig. 151, is the size of 381 the Turtle Dove; the ground of its plumage is of a yellow colour, speckled over with brown spots. In winter it is always numerously represented in our markets: this is occasioned by the ease with which it can be either shot or netted.
The Pluvian may be considered as belonging to the Plovers, as the difference between them is altogether insignificant. We wish to mention it on account of its very curious habits, to which we previously called attention when speaking of Reptiles. This bird is a native of Egypt and Senegal, and has concluded a friendly treaty with the Crocodiles of the Nile, which must force itself on the meditations of philosophers. The Pluvian does the Crocodile the service of picking the latter's teeth. This assistance rendered by the little bird to the terrible reptile of the Nile is really rather touching, and has somewhat the appearance of having inspired La Fontaine with his fable of the "Lion and the Mouse."
The Bustards (Otis) are allied to the Gallinaceæ by their short back, their thick-set shape, and the general character of their habits; but their elongated tarsi, and their legs partly bare, give them a position among the Grallæ. They have short toes, and no back toe; they run with extreme rapidity, assisted by their wings. Their flight is heavy and awkward. They frequent dry and open plains, and make their nests on the ground. Their food consists of worms, insects, grasses, and even seeds; and they move about in large droves, although their range is rather restricted. The male birds being less numerous than the females, they are generally polygamous. These birds are shy and timid, and their flesh constitutes an excellent article of food.
There are three species of the Bustard—the Great Bustard, the Little Bustard (Fig. 152), and the Oubara Bustard (O. Denhami).
The Great Bustard (Otis tarda) is the largest of all European birds; its weight sometimes attains to sixteen kilogrammes. It is yellow on the back, with black streaks, and in front it is a greyish white. The head of the male bird is ornamented on both sides with curled feathers, which look something like moustaches, and have obtained for it the name of the Bearded Bustard. It flies with great difficulty, and will never make up its mind to take wing 382 except in cases of absolute necessity. Its eggs, two or three in number, are laid in the corn or grass; the nest is nothing more than a hole scratched out in the earth, and with scarcely any lining on the inside.
The Great Bustard was formerly very common in Champagne, but has now become extremely rare. Nevertheless, it is the only province in France in which this bird is to be met with, and we might almost say that it has completely disappeared from French soil. Innumerable troops of them are to be seen in the steppes of Tartary and Southern Russia.
The birds belonging to this family are distinguished from the rest of the Grallæ by such decisive characteristics that some naturalists have proposed to include them in a separate group, to be called Cursores, or Runners; an arrangement which has much in its favour, although the simpler arrangement of Cuvier best suits our purpose. In certain anatomical points, and especially 383 in their habits, the Brevipennæ differ greatly from the other Grallatores. They have wings, it is true, but they are so slightly developed that they are entirely unfit for purposes of flight, and are only useful in accelerating the speed of their limbs. On the other hand, their legs are long and powerful, and capable of immense muscular effort, thus enabling them to run with extraordinary fleetness.
The deduction to be drawn from these facts is, that the Brevipennes are essentially land-birds. This limitation of their habitat necessitated certain modifications in the sternum, which, instead of a prominent edge of bone in the centre, as in other birds, only presents one uniform breast-plate. Again, most of the Brevipennes are birds of large size, and, in certain circumstances, manifest remarkable vigour.
This group comprehends the Ostrich (Struthio camelus), the American Nandou (Rhea americanus), the Cassowary (Casuarius emu), and the Apteryx.
The head of the Ostrich (Struthio camelus), Fig. 153, is naked and callous, with a short bill, much depressed and rounded at the point; its legs are half naked, muscular, and fleshy; the tarsi are long and rough, terminating in two toes pointing forward, one of which is shorter than the other, and has no claw; the wings are very short, and formed of soft and flexible feathers; the tail taking the form of a plume.
There is but one species of the Ostrich; it is sparsely diffused over the interior of Africa, and is rarely found in Asia, except, perhaps, in Arabia. It is the largest member of the Grallatores, generally measuring six feet in height, and occasionally attaining nine feet; its weight varies from twenty to a hundred pounds.
The Ostrich has been known from the most remote antiquity. It is spoken of in the sacred writings, for Moses forbade the Hebrews to eat of its flesh, as being "unclean food." The Romans, however, far from sharing the views of the Jewish legislator, considered it a great culinary luxury. In the days of the emperors they were consumed in considerable numbers, and we read that the luxurious Heliogabalus carried his magnificence 384 so far as to cause a dish composed of the brains of six hundred Ostriches to be served at a feast: this must have cost some hundreds of thousands of francs. In former days it was a favourite dish with the tribes of Northern Africa. At the present date the Arabs content themselves with using its fat as an outward application in certain diseases, especially rheumatic affections; and they derive from it, as they say, very beneficial effects.
The natives of Africa call the Ostrich "the Camel of the Desert," just as the Latins denominated it Struthio camelus. There is, in fact, some likeness between them. This resemblance consists in the length of the neck and legs, in the form of the toes, and in the callosities which are found on the lower stomach of both. In some of their habits they also resemble each other; the Ostrich lies down in the same way as the Camel, by first bending the knee, then leaning forward on the fleshy part of the sternum, and letting its hinder quarters sink down last of all.
An entire volume might be filled with the fables recorded about the Ostrich. In the first place, according to the Arabs, it is the issue of a bird and a camel. One Arabian author states that it is aquatic in its nature, another maintains that it never drinks. They still assert that its principal food consists of stones and bits of iron. Buffon himself does not deny that it might swallow red-hot iron, provided the quantity was small. Pliny and (following him) Pierre Belon, the naturalist of the Renaissance, state that when the Ostrich is pursued it fancies itself safe if it can hide its head behind a tree, caring little about the remainder of its body; and some of these absurd ideas are still deeply rooted in the minds of the public.
It is certain, however, that the Ostrich is extremely voracious. Although the senses of sight and hearing are so highly developed that it is said to make out objects two leagues off, and the slightest sounds excite its ear, the senses of taste and smell are very imperfect. This is the explanation given for its readiness to swallow unedible substances. In a wild state it takes into its stomach large pebbles to increase its digestive powers; in captivity it gorges bits of wood and metal, pieces of glass, plaster, and chalk, probably with the same object. The bits of iron found in the body of one dissected by Cuvier "were not only worn 385 away," says the great naturalist, "as they would likely be by trituration against other hard bodies, but they had been considerably reduced by some digestive juice, and presented all the evidence of actual corrosion."
Herbage, insects, mollusks, small reptiles, and even small mammalia are the principal food of the Wild Ostrich; when it is in a state of domesticity even young chickens are frequently devoured by it. It endures hunger, and especially thirst, for many days—about the most useful faculty it could possess in the arid and burning deserts which it inhabits; but it is quite a mistake to suppose it never drinks, for it will travel immense distances in search of water when it has suffered a long deprivation, and will then drink it with evident pleasure.
The muscular power of the Ostrich is truly surprising. If matured it can carry a man on its back, and is readily trained to be mounted like a horse, and to bear a burden. The tyrant Firmius, who reigned in Egypt in the third century, was drawn about by a team of Ostriches; even now the negroes frequently use it for riding.
When it first feels the weight of its rider, the Ostrich starts at a slow trot; it, however, soon gets more animated, and stretching out its wings, takes to running with such rapidity that it seems scarcely to touch the ground. To the wild animals which range the desert it offers a successful resistance by kicking, the force of which is so great that a blow in the chest is sufficient to cause death. M. Edouard Verreaux states that he has seen a negro killed by such a blow.
Man succeeds in capturing the Ostrich only by stratagem. The Arab, on his swiftest courser, would fail to get near it if he did not by his intelligence supply the deficiency in his physical powers. "The legs of an Ostrich running at full speed," says Livingstone, the traveller, "can no more be seen than the spokes in the wheel of a vehicle drawn at a gallop." According to the same author, the Ostrich can run about thirty miles in an hour—a speed and endurance much surpassing those of the swiftest horse.
The Arabs, well acquainted with these facts, follow them for a day or two at a distance, without pressing too closely, yet 386 sufficiently near to prevent them taking food during the time. When they have thus starved and wearied the birds, they pursue them at full speed, taking advantage of the fact which observation has taught them, that the Ostrich never runs in a straight line, but describes a curve of greater or less extent. Availing themselves of this habit, the horsemen follow the chord of this arc, and repeating the stratagem several times, they gradually get within reach, when, making a final dash, they rush impetuously on the harassed birds, and beat them down with their clubs, avoiding as much as possible shedding their blood, as this depreciates the value of the feathers, which are the chief inducement for their chase.
Some tribes attain their object by a rather singular artifice. The hunter covers himself with an Ostrich's skin, passing his arm up the neck of the bird so as to render the movements more natural. By the aid of this disguise, if skilfully managed, Ostriches can be approached sufficiently near to kill them.
The Arabs also hunt the Ostrich with dogs, which pursue it until it is completely worn out. In the breeding season, having sought and found out where the Ostriches lay their eggs, another artifice is to dig a hole within gunshot of the spot, in which a man, armed with a gun, can hide himself. The concealed enemy easily kills the male and female birds in turn as they sit on their nest. Lastly, to lie in wait for them close by water, and shoot them when they come to quench their thirst, is often successful.
The Ostrich, which is an eminently sociable bird, may sometimes be seen in the desert in flocks of two or three hundred, mixed up with droves of Zebras, Quaggas, &c. They pair about the end of autumn.
The nest of the Ostrich is more than three feet in diameter; it is only a hole dug in the sand, and surrounded by a kind of rampart composed of the débris; a trench is scratched round it outside to drain off the water. Each hen bird lays from fifteen to twenty eggs, according to circumstances. The eggs weigh from two to three pounds, and are each of them equal in contents to about twenty-five Hen's eggs. They are of a tolerable flavour, and are often a very seasonable help to travellers, one of them being more than sufficient for the breakfast of two or three persons. 387
388
Incubation usually takes six weeks, and is shared by both male and female birds: several of the latter often lay in the same nest, and live together on the best terms, under the control of one male. Levaillant remarked four females taking turns in sitting on thirty-eight eggs laid in the same nest: they sat during the night only, the burning heat of the sun during the day being sufficient to maintain the necessary degree of warmth. He also observed that a certain number of the eggs were not sat upon, but were put aside to serve as nourishment for the young ones after they were hatched.
It is a strange circumstance that the cry of the Ostrich so much resembles that of the Lion when in search of his prey, that they are often confused. Dr. Livingstone says that with all his experience he has been frequently deceived, and that only the quick ear of a native can detect the difference.
It was long a subject of reproach to the Ostrich that she was wanting in affection for her progeny. She was looked upon as the most striking example of the hard-hearted mother. Thus, the Hebrews accepted the Ostrich as the symbol of insensibility, because she left her eggs upon the sand, without troubling herself, as Job says, about the dangers to which they might be exposed. Jeremiah, too, laments over her that she is devoid of family affection. All these accusations are quite unfounded: as we have already seen, the Ostrich does not abandon her eggs, neither does she desert her young, although they are well covered at their birth with a thick, warm down, and can from the first run about and provide for their own wants. On the contrary, she keeps them near her until they are almost full grown, and defends them against every enemy. Mr. Cumming came suddenly one day on a dozen young Ostriches no larger than full-grown Grouse. "The mother," he says, "tried all she could to deceive us, just like a Wild Duck; first she ran away, extending her wings; then she threw herself on the ground as if she was wounded; whilst the male bird cunningly enough conducted the young ones in an opposite direction."
Livingstone on several occasions met with broods of young Ostriches led by a male bird, which pretended to be lame, in order to monopolise the attention of the sportsmen. 389
Both the male and female birds afford one another mutual assistance, as is proved by the following fact, which was related in a report addressed to the Société d'Acclimatation:—"Si-Djelloul-Ben-Hamza and his brother, Si-Mohammed-Ben-Hamza, were one day hunting Ostriches, and came upon the tracks of a family led by a male and two females. Si-Mohammed arrived first in sight of the birds, and firing, wounded one of the females. The male bird at once darted at him, and struck with its feet at the breast of his horse, which from fright threw its rider and ran away. The Ostrich then turned upon Si-Mohammed, kicked him repeatedly, and did not quit him until he had lost all consciousness, and his brother Si-Djelloul had come to his assistance."
All these facts abundantly prove that the Ostrich is not so unnatural a parent as it has been thought, and at the same time give a complete denial to the accusation of stupidity which has also been made.
In spite of its great strength—perhaps even on account of it—the Ostrich, when unmolested, is the most peaceable creature in the world; and owing to its inoffensive nature, it readily becomes domesticated. If captured young, it can be tamed in a very short time. General Daumas asserts that they play with the children, and frolic with the horses and dogs, &c. In the district of Sennaar they are reared as we do Fowls; they are left to wander about as they choose, and one of them attempting to escape is a thing quite unheard of. They accompany the herds to pasture, and return again to their home at meal-times. Kindness and caresses are sufficient to attach them to any one; but care must be taken never to strike them. They have but one fault, which arises from their voracity,—they are dreadful thieves, and devour everything they can steal. The Arabs, therefore, always look out when they are counting their money, otherwise the Ostriches might snatch some of the coin.
In all ages the feathers of the Ostrich have been the object of considerable trade: the birds are hunted and reared in a domestic state, not so much for their flesh, grease, or eggs, as for these plumes. Each bird produces about half a pound of white feathers and three pounds of black. These delicate, wavy, and flexible 390 ornaments, so sought after by the fair sex, are found on the Ostrich's tail and wings; they have been used from time immemorial for the adornment both of man and woman. The Roman soldiers decked their helmets with them, and the Janissaries their turbans, when they had distinguished themselves by any glorious deed. At the present day there is a large demand for them. The plumes of the male bird are more highly valued than those of the female, and all are superior when plucked from the living bird.
Several Libyan nations in former days used the skin of the Ostrich for a cuirass, and even at the present time some Arabian tribes put it to the same use. The shells of Ostrich eggs, which are very hard, are also utilised; they are made into beautiful cups, which much resemble vases of ivory. The Africans annually destroy a large number of these birds; yet their race does not appear to diminish. It is a most useful creature, and too much encouragement cannot be given to the trials which have been made in Algeria and elsewhere to rear the Ostrich in flocks on an extensive scale.
The Nandou, Rhea, or American Ostrich (Fig. 154), bears the greatest resemblance to the Ostrich, of which it is the representative in the New World; but it is only about half the size of the African bird, and has three toes in front instead of two. The colour of its plumage is a uniform grey.
The Nandou (called by the Brazilians Nhandu-Guaçu) inhabits the Pampas of South America, the coolest valleys in Brazil, Chili, Peru, and Magellan's Land. There these birds may be seen wandering over the open plains in flocks of about thirty, in company with herds of oxen, horses, and sheep. They browse on the grass like grazing animals, searching at the same time for various seeds. They run nearly as swiftly as the Ostrich, and are well able, by speed, to escape the pursuit of their enemies. If a river comes in their way, they do not hesitate to plunge into it, as they are excellent swimmers; indeed, so fond are they of water that they take a pleasure in washing and bathing.
The Nandou lays its eggs and incubates them in the same manner as the Ostrich. They are birds of a gentle nature, and 391 are tamed with the greatest ease, becoming very familiar in the house, visiting the various apartments, wandering about the streets, and even into the country; but they always return to their homes before sunset.
The flesh of the adult Nandou is by no means agreeable; that of the young, on the contrary, is tender and sweet, and forms excellent food. Its skin, when properly dressed, is used for bags, purses, &c., and their feathers serve for plumes and light dusting brooms. We owe the perfect knowledge of a second species of Rhea to Mr. Darwin, who has given a figure and ample descriptions of the bird and its habits in "The Voyage of the Beagle;" it has been named in consequence Rhea Darwinii. There is every 392 reason for thinking that these birds might be successfully acclimated in Europe.
The Cassowaries form a genus of birds allied to the Ostrich, although they differ from it in some particulars—their shape is not so elegant, and their wings are even less adapted for flight; for so short are they, that they are perfectly useless even to assist in running. Their long blackish feathers are almost devoid of side fringes, which gives them a resemblance to coarse hair; their feet are provided with three toes. This bird was called the Emu by early Portuguese navigators. It is the Struthio casuarius of Linnæus, the Casuarius galeatus of Vieillot, and the Cassowary of British naturalists.
The Cassowary has a kind of helmet on its head, produced by an enlargement of the bone of the skull, and covered with a horny substance. It is a massively-made bird, in size between the Ostrich and the Rhea, and is a native of the islands of the Indian 393 Archipelago, the Moluccas, Java, and Sumatra. It is especially plentiful in the vast forests of the island of Ceylon. The first bird of this species which was seen in Europe was brought from Java by the Dutch in 1597. It is a stupid, quarrelsome, and gluttonous creature, feeding on plants, fruits, and sometimes small animals. Possessed of considerable strength, and being wild and fierce in nature, its anger cannot be provoked without danger; for, although its wings are short, each is furnished with five pointed spines, the middle one of which is a foot long, and which are employed with adroitness as weapons of defence. Its habitual cry consists of a low grumbling, which, when the bird is angry, is changed into a sonorous humming noise, not unlike the sound of carriage-wheels or of distant thunder.
The menagerie of the Museum of Natural History at Paris was in possession of a Cassowary which devoured everything that was given it—bread, fruit, vegetables, &c., and drank seven or eight pints of water daily. In the London and the Paris Zoological Gardens there are generally several to be seen.
The Cassowary runs very swiftly, and in a way quite peculiar, for it kicks up its heels at every step. They live in pairs, and during the breeding season the male bird shows a degree of violence which renders him very formidable. The female lays three or four eggs in the dust, and sits on them alone for about a month. The young birds, when first hatched, are covered with a light down, and are without the helmet, which it acquires as it approaches maturity.
The wild nature of these birds renders them but little fitted for domestication: this is a fact not much to be deplored, as their flesh is of an unpleasant flavour, and in no other respect than as food could they be of any service to us.
The Emu, or Australian Cassowary (Dromiceius australis), Fig. 156, is distinguished from the last-named bird by its larger size, and also by the absence of the helmet, the caruncles, and the pointed spines on the wings. It was formerly common in the great forests of the Eucalyptus, in Australia, but the clearings of the colonists have now driven it back beyond the Blue Mountains. Being very powerful, it offers a stout resistance to dogs, with which it is hunted. It can be tamed much more easily 394 395 than the last-mentioned bird, and manifests some attachment to its master. It is an excellent and useful acquisition to man, for its flesh being of an agreeable flavour, is much esteemed. The few specimens which have been brought to Europe seem to have been readily acclimated, for they have bred.
Kivi-kivi, or Apteryx (Fig. 157), so called from the Greek απτερον, "wingless," is a singular bird, bearing but little resemblance to the other members of the class. It is no larger than a Fowl, and combines the bill of the Woodcock with the feet of the Gallinaceous tribe. The shortness of its wings, which are entirely unfit for flight, is the sole characteristic which entitles it to rank with the group in which it is placed.
The plumage of the Apteryx is brown; it has no tail, and its mere stumps of wings are provided with strong and curved claws. It is a native of New Zealand, and keeps in the marshes, where it feeds on worms and grubs: being nocturnal, it does not leave its retreat until the evening. In spite of its short legs, it runs very fast, but if overtaken does not yield without an effort, using either its feet, armed as they are with long and sharp claws, or the points at the end of its wings, as weapons of defence. It builds a very rough nest among the roots of marsh-growing shrubs, and lays a single egg, excessively large in proportion to the size 396 of the producer. The natives call the bird Kiwi. They used at one time to hunt them very perseveringly, as much for their flesh as for their feathers, which they used in making mats. Now they have renounced this work, the profits not compensating for the fatigue which it entailed. Day by day it is becoming more rare and difficult to procure. The Zoological Society of London has three specimens.
The order of the Brevipennæ may be held to embrace some birds which have now disappeared from the surface of the globe, but which are supposed to be contemporaneous with Man. The remains which are met with in quite modern alluvium scarcely admit of any doubt in this respect.
In the first rank of extinct birds we may place the Dodo (Didus ineptus, Linn.), Fig. 158, which was indigenous to the Mauritius and the Isle of France, where it used to be abundant, if we may believe the testimony of the companions of Vasco de Gama, who visited there in 1497. At the end of the seventeenth century some of them still existed. Former travellers have described them; and these accounts, with skeletons and an oil-painting in the British Museum, are the only items of information which we possess.
The Dodo was a fat and heavy bird, and weighed not less than fifty pounds. This portly body was supported on short legs, and provided with ridiculously small wings, making it equally incapable of running and flying, dooming the bird to a rapid destruction. Lastly and principally, it had a stupid physiognomy, but little calculated to conciliate the sympathies of the observer. Its rear was decorated with three or four curly feathers, making a pretence of a tail, whilst in front it presented an enormous curved bill, which occupied nearly the whole of the head.
The Dodo did not even possess the merit of being useful after its death, for its flesh was disagreeable and of a bad flavour. On the whole, there is not much reason to regret its extinction.
In the island of Madagascar fossil eggs and bones were found of a bird belonging to a species probably extinct, the proportions 397 of which must have been truly colossal. One of these eggs was equal to at least six Ostrich's eggs, and its capacity more than fifteen pints. M. Isidore Geoffroy de Saint-Hilaire, who gave it the name of Epiornis, reckoned that its height could not be less than ten or twelve feet.
In 1867, M. Joly, Professor of the Faculty of Sciences at Toulouse, published some very interesting observations on the structure and probable habits of this gigantic bird.
It cannot yet be asserted that this bird has altogether disappeared. The Malagashes state that, although very rare, some few representatives of it still remain. There is an ancient tradition among this people relative to a colossal bird which could knock down an ox, and then make a meal of it. This tradition, however, is deficient in anything like evidence of its correctness, for an examination of the pieces of bone found proves that the Epiornis possessed neither talons to seize, nor wings with which to pursue its prey; it must, therefore, have fed chiefly upon vegetable diet.
In New Zealand also some bones have been lately brought to light, which must have belonged to a species of bird allied to the Ostrich, but superior to it in size, which attained some thirteen feet in height. This bird has been designated Dinornis. Some of 398 them probably still exist in that country; at all events, its disappearance must be very recent, for the bones which were discovered still contained a large proportion of gelatine. Rumour states that a Dinornis, more than thirteen feet in height, was seen by two Englishmen in one of the marshy forests; but they did not venture to approach near enough to kill it. We give this tale with all due reserve, as its authenticity does not appear to be satisfactorily established. 399
Under this name Linnæus included a large number of birds which bear considerable analogy to the Domestic Fowl, and mostly included in the Rasores of Illiger.
The Gallinaceæ are essentially land birds, seeking their food on the surface of the soil, and frequently building their nests upon it. They delight in scratching the earth, and in rolling themselves in the dust. Walking is their habitual mode of progression, as one would at once conclude from observation of their strong legs, and their short and but slightly-bent claws. Some, like the Partridge, are swift runners, having very short wings, which render their flight at once awkward and laborious. In this order of birds we do not find more than two or three migratory species.
The Gallinaceæ have short arched beaks, which are generally very strong, and well adapted for crushing the husks of the seeds which, with the addition of grubs, insects, and grasses, form their principal nourishment. Their large and muscular gizzards, with thick lateral muscles, lined on the interior with a very tough coating or epithelium, are exactly fitted for digesting this kind of food. The triturating power of the Gallinaceæ is further increased by their habit of swallowing small pebbles, which facilitate the crushing of the grain.
In certain species (the Domestic Fowl, Pheasant, Turkey, &c.) the males are armed above the back toe with one or more 400 tapering spikes (a kind of very stiff spur), which they use both for attack and defence. A great many of this class have their heads adorned with crests and combs of various colours. These appendages exist occasionally in the females, but with much less development.
Birds of the most brilliant plumage are to be found among the Gallinaceous tribe. The Peacock (Pavo), the Argus, the Lophophore, and the Pheasant may be said to bear the banner of their order with no mean degree of splendour, and may worthily stand in comparison with the most splendid of the Passerines. This richness of colour is the characteristic of the male bird, for the females are usually of a dull greyish hue. But if the Gallinaceæ captivate the sight, they are far from affording pleasure to the ear, their cries being shrill and discordant.
Cruel, tyrannical, and quarrelsome are the characteristics of the majority of this race. They are polygamous, and the females lay a large number of eggs, which they sit upon, unassisted by the male. They are generally divided into flocks, consisting of one male, several females, and a number of young birds; but it is rarely that several families unite to live in common.
The Gallinaceæ are of all birds the most useful to man. Certain domesticated kinds stock his poultry-yard, and supply him with eggs of an exquisite flavour; nor does their utility cease here—their flesh is a popular, wholesome, and delicate food. Those known as "game birds" are also abundant, and offer amusement to the sportsman and table delicacies for the bon vivant.
Nearly all the Gallinaceæ were originally natives of the warm regions of Asia and America; now, such as the Domestic Fowl, the Pheasant, and the Turkey are perfectly acclimated to all temperate parts of the globe.
The order of the Gallinaceæ may be divided into two great sub-orders, namely, the Gallinaceæ proper, to which the characteristics we have just enumerated specially belong; and the Columbidæ, which differ from them in certain details of organisation and habits, to be described hereafter. 401
Comprehend six families: the Tetraonidæ, the Perdicidæ, the Tinamidæ, the Chionidæ, the Megapodidæ, and the Phasianidæ.
The birds which compose this group are characterised as follows:—Tarsi completely feathered; a naked and knotty band of skin supplying the place of eyebrows; the body bulky; and the wings short. This family comprehends several species. The best known we enumerate:—The Cock of the Woods (Tetrao urogallus), the Black Grouse (Tetrao tetrix), Cock of the Plains (Tetrao artimesia), the Pinnated Grouse (Tetrao Cupido), the Ruffed Grouse (Tetrao umbellus), the Hazel Hen, or Gelinotte (Bonasia europæa), and the Ptarmigan (Lagopus).
The Cock of the Woods, or Capercailzie (Tetrao urogallus), inhabits the pine and birch forests of northern hilly countries. They feed indifferently upon fruits, berries, the buds of fir and birch trees, insects and grubs—nothing, in fact, comes amiss to satisfy their appetites. Their bearing, which is proud and warlike, is supported by a robust form. Their plumage is black, spotted with white, and clouded, as it were, with bluish diaphanous shades. They are polygamous, and live together in families. They readily seek shelter in the trees, both for roosting and in order to conceal themselves from their enemies.
At the first breath of spring the male birds make the woods re-echo with the loud notes with which they summon the females to come to them. For an hour every morning and evening, for over a month, this practice is continued.
The females retire into the thick brushwood to build their nests and lay their eggs: here they devote themselves to incubation, and afterwards to rearing their offspring—cares which devolve upon them exclusively. They deposit from eight to sixteen eggs on a bed of grasses and leaves roughly interwoven. The young birds run about as soon as hatched, and remain for several months 402 with the mother, who on all occasions watches them with the tenderest solicitude.
The flesh of the Cock of the Woods is juicy, but is esteemed more for its rarity; for the buds and leaves of the pines, which are its favourite food, give it a flavour of turpentine. In Scotland this species became extinct, but was restored by the Marquis of Breadalbane and others, who imported great numbers from Sweden. It is almost as large as a Turkey.
The Black Grouse (Tetrao tetrix), Fig. 159, is about the size of a Pheasant, and is distinguished by its tail, which in the cock is divided into two parts, with a curling notch, composed of four lateral feathers on each side, curving outwards.
The Cock of the Plains (Tetrao artimesia, Aud.), so called from frequenting and feeding on the sage that grows in profusion on the far-western prairies of America, is a noble bird, of handsome plumage. It is almost as large as a hen Turkey. Its numbers are rapidly diminishing.
The Pinnated Grouse (Tetrao Cupido, Aud.) is a native of the prairies of the North American continent; it is the same size as the last-described species, but the plumage is a light brown, occasionally ticked with white. Its call is deep and sonorous, much resembling the bellowing of a bull, and can be heard for miles in still weather. It is an excellent table bird, and 403 affords good sport to the lovers of the gun. The Pinnated Grouse, frequently called Prairie Chicken or Hen, pair in March; they lay from twelve to fourteen eggs, and are most devoted parents. Of this species there are two strongly-marked varieties, differing in size and formation of tail.
The Ruffed Grouse (Fig. 160) is also an American bird, but differs essentially from the last mentioned in size, habits, and selection of food. The hill-sides, densely covered with evergreens or birch, are its favourite retreats; on the wing it is remarkable for its swiftness. Although not migratory, it is very erratic.
The Hazel Grouse, or Gelinotte (Bonasia europæa, Gray), inhabits the same description of country, and has habits very similar to the Black Grouse. Like them, it is suspicious and timid, and hides itself among the thick foliage of the green trees at the least appearance of danger. This bird flies awkwardly, but runs very swiftly. Its flesh, which is both delicate and savoury, brings a high price in the market. It is much less rare in France than the Cock of the Woods, and is frequently met with in the departments of Vosges and Ardennes. It is about the size of a Partridge, and the prevailing colour of its plumage is a reddish brown mixed with white, or variegated with 404 grey and brown: the male has a large black patch under the throat.
The Ptarmigans have feet much like those of a hare, and thence is derived the name Lagopus, which signifies "hare-foot" (λαγος, hare; πους, ποδος, foot). These birds not only have their tarsi covered with feathers, but also their toes and the soles of their feet.
The icy regions of both hemispheres, and the summits of lofty mountains, are their domain. The snow is their favourite resting-place; they delight in rolling in it, and turning it over in search of food, or forming holes in which they pass the night to take shelter from the storm.
The colour of Ptarmigans is perfectly suited to the northern solitudes they inhabit. Their plumage is of a brilliant white, save one line of black on the head, and some tail-feathers of the same colour. This is their winter costume. In the summer, when the snow has disappeared under the scorching rays of the sun, they change their plumage, and are clothed in a habit of a greyish colour, spotted with brown and red (Fig. 161). Like the Cock of the Woods and the Hazel Hen, they are birds of social habits, and cannot bear captivity. When kept in confinement they become sickly, and soon fall into decline. Their flesh is excellent and much prized. Numbers of them are sold in the markets, and considerable quantities are sent every year to England and France 405 from Scotland, Norway, and Lapland. The two principal species are the Lagopus mutus, common in the Alps, the Pyrenees, and the North of Europe and America; and the Red Grouse (Lagopus scoticus, Selby), which is found only in Great Britain and Ireland, where it is much prized for its beauty, delicacy of flesh, and the magnificent sport it affords when killed over dogs. The 12th of August, the first day of Grouse-shooting, is looked forward to by the disciples of the gun as anxiously as the Derby day by turfmen.
The distinctive features of the birds composing this family are—a short beak, a small head, a round and massive body, bare tarsi, with spurs more or less developed, and a middling-sized back toe. The wings are sharp, pointed, or blunt, according to the species. This family comprehends the Gangas (Pterocles, Temm.), Syrrhaptes (Ill.), Quail (Coturnix), Partridge (Perdix, Briss.), Colin (Ortyx, Steph.), Francolin (Francolinus, Briss.), and Turnix (Bonap.).
The Gangas, or Attoyens, are essentially birds of passage, and in consequence are provided with long and sharply-pointed wings; but the range of their journeys is not very great. They resemble the Plover in their power of lofty, rapid, and sustained flight, 406 and inhabit the arid plains of Southern Europe, Asia, and Africa.
The Pin-tailed Sand Grouse (Pterocles setarius), Fig. 162, annually makes its appearance in Spain and the South of France; it is common on the steppes of Southern Russia, of Tartary, Manchuria, Northern China, and in the North of Africa. Occasionally it breeds in the Pyrenees.
The Syrrhaptes, or Heteroclites, are characterised by the total absence of the back toe. They are closely allied to the Gangas, and, like them, have pointed wings, and are fond of travelling, but their flight is not so continuous, for in their journeys they are frequently compelled to alight. They inhabit the steppes of Tartary, and but rarely venture into Europe.
The Quail (Perdix coturnix, Latham) has a small beak, a short back toe inserted rather high up, tarsi furnished with a rudimentary spur in the shape of a horny tubercle, a thick-set body, sharply-pointed middling-sized wings, and hardly any tail. There are several species of this bird, only one of which is found in Europe.
The Common Quail (Fig. 163) is noted for its migrations. Every year innumerable flocks of them leave the regions of Africa, cross the Mediterranean, and, about the commencement of May, spread themselves over Europe. In the month of September they return, again accomplishing the same journey. The instinct which impels them to migrate from one country to another is so powerful that it is observed in Quails which are born in captivity. At the season of migration captive Quails become very uneasy, walk up and down their cages, and throw themselves against the bars with such force that they frequently fall back stunned, and sometimes even crush their skulls.
When it is considered that the Quail is a heavy bird, with wings comparatively small, and that it must cost them great labour to migrate, it is evident that it must be undertaken under strong impulse: probably the necessity of escaping the severity of winter, or of providing for their sustenance, is not the only cause, but that there is some sort of instinctive want, equally imperative with that of hunger, under which the birds are irresistibly forced to traverse such indefinite distances. 407
408
The fecundity of the Quail is extraordinary: if it were otherwise the species would soon be exterminated, partly from their heavy, awkward flight, which renders them an easy prey to the sportsman's gun, but still more from the wholesale slaughter of them which takes place in certain districts at the time of migration. The Bishop of the island of Capri, situated in the Bay of Naples, receives an annual revenue of forty thousand francs (£1,600 sterling) from the duty he has imposed upon trading in Quails killed on the island, which are afterwards sold in the markets of Naples. From this he has received the name of the "Bishop of the Quails."
On the shores of the Bosphorus, in the Morea, Crimea, and in some of the islands of the Grecian Archipelago, Quails sometimes arrive in such dense masses that, according to a popular saying, it is only necessary to stoop in order to pick them up. They fall exhausted upon the ground, and the sky may almost be said to be raining birds. The inhabitants, who have been watching for them for many days, now net them in great numbers, and, having salted them, and packed them in barrels, export them to different countries.
Quails travel principally in the evening and during the night. They ascend to a tolerable height, but never fly against the wind; but, on the contrary, scud before it, and are thus carried across the Mediterranean. The south winds bring them to us, and the north winds carry them back to Africa. If overtaken by a tempest during their passage, they have not power to resist it, but fall into the waves. Thousands of them have been found drowned around the precipitous portions of the island of Malta; their strength had failed them, and, from being unable to gain sufficient elevation, they found a watery grave. They also take shelter occasionally on the decks of passing vessels.
Quails principally frequent plains covered with cereals or fertile pastures. They delight in rolling in the dust, and are never known to perch. Their food consists of seeds and insects. They are not sociable birds; for the sexes do not approach one another except in the breeding season, and parent and young separate as soon as the mother's care is no longer necessary for the protection of the brood. This period soon arrives, as the little 409 410 things are of rapid growth. The hen birds lay twice during the year, once in Europe and once in Africa, and each time produce from ten to fourteen eggs.
The Quail is a very swift runner, and frequently employs this mode of locomotion to escape pursuit. It is only in cases of imminent danger that it has recourse to flight. It flies in a straight line, keeping close to the ground, and shows itself a thorough master in the art of baffling dogs by throwing them off their scent. Hidden in the thick tufts of lucern, it often bids defiance to the novice; but its wiles are seldom successful before an experienced sportsman.
This bird is not as large as the Partridge. When killed at the proper time—that is to say, when it has rested after its fatiguing journey and recovered condition—it is covered with a layer of fat which is not surpassed in richness and flavour by any other bird. Its flesh is sweet and delicate, and emits an odour grateful alike to the nose and palate. This bird ranks immediately after the Woodcock and the Snipe in the estimation of epicures.
The capture of Quails was formerly performed in several ways. They were caught in a net or a trap, in which a bait was placed: they were also shot with the help of a pointer. This last method is the only one which is nowadays allowed in France; and, thanks to this restriction, the bird is now destroyed on a less extensive scale than in times past, and the species may yet be something more than a myth to future generations.
The Partridge (Perdix) has a sharply recurvate beak, a thick-set body, blunt wings, and a short and drooping tail. The tarsi of the male bird are either provided with, or destitute of, tubercles, according to the species.
Partridges live constantly on the surface of the soil, and never perch except when they are absolutely forced to do so. They have, like the Quail, the pulverulent instinct, and run with remarkable swiftness. Their flight is also very rapid, but low, and does not extend to long distances.
These birds are eminently sociable, and live, during the principal part of the year, in flocks or coveys, composed of the parents and the young ones of the last brood. They are not migratory, and seem to attach themselves to certain localities, confining 411 themselves to a limited extent of country, in which they pass their lives. They never leave this except by accident. In it they make choice of a sanctum in which to take shelter when pursued; this is called by sportsmen a "cover."
Partridges are monogamous; they pair early in the year, which union does not cease until the following spring.
In certain species, such as the Red Partridge, where the females are less numerous than the males, a great number of the latter remain single. As the cocks do not willingly resign themselves to single blessedness, but make many attempts to avoid it at the expense of their neighbours, this is the cause of frequent quarrels. These conflicts at last come to an end—the various pairs are firmly united; and the unsuccessful candidates for affection, who object to making up their minds to live as hermits, ultimately combine together.
The attachment of the male to the female is deserving of admiration. At the time for laying, the hen bird makes a hole in the earth, which she lines with grass and leaves, and in it deposits her eggs, to the number of twelve or fifteen, and sometimes even twenty or more. The season of incubation follows after, which lasts twenty days at least. During this time the male bird watches over his companion, and guards her from danger. When the young are hatched, paternal affection is added to conjugal love, and a portion of the father's care is devoted to the young brood. He accompanies them in their wanderings; he teaches them to catch grubs, finds ants' eggs, and shows himself as skilful as the mother in guarding them from attacks of their enemies. At the appearance of the sportsman or dog the male utters a cry of alarm, which warns the young ones of their danger, and enjoins them to seek concealment. Drooping his wings in order to induce the intruder to follow him, he pretends to fly away. At the same time the female proceeds in another direction; and alighting at some distance off, she runs back to her family, reassembles them, and leads them to a place of security, where they are soon joined by the male bird. The above is one of the ingenious stratagems by which the young brood is defended from pursuit.
Some weeks after they are hatched, the young Partridges are fit to fly and to provide for their own wants. As we have already 412 413 said, they do not now leave their parents, but continue to live with them in the closest alliance until February or March, at which time they separate in order to pair off. At this time, also, the union of the father and mother comes to an end, and they generally form a fresh alliance.
Partridges are of a shy and timid nature, which shows itself in many ways. Nor are their suspicious fears unjustifiable, when it is remembered how numerous are their foes, for foxes and birds of prey make continual and unsparing war upon them. The latter especially are particularly dreaded. At the mere sight of one of the Falcon tribe a Partridge will stop as though struck with stupor, and so overcome with fear as almost to be incapable of concealing itself, remaining absolutely immovable; and it is not until the dreaded enemy is gone that it regains self-control.
When a bird of prey dashes at one of them unsuccessfully when in cover, no human power is able to make it abandon its retreat, and any one can then lay hands on it without difficulty. A Partridge has even been known to allow itself to be stifled with smoke in its hiding-place rather than again expose itself to the claw of the Falcon, Vulture, or Sparrow-hawk.
The knowledge of these facts has suggested a very simple and effectual method of killing Partridges successfully. This consists in frightening them with the help of an artificial bird of prey, attached to the tail of a kite flown over them. While the Partridges are paralysed by fright from this deception, the sportsmen advance and make the birds flush within easy shooting distance.
Notwithstanding their wild nature, Partridges are susceptible of domestication, and, with care and gentleness, they may be rendered very tame. Girardin relates that a Grey Partridge, reared by a Carthusian, became so familiar that it followed its protector about like a dog. Willoughby states that an inhabitant of the county of Sussex succeeded in taming a whole covey of Partridges, and was in the habit of driving them before him like a flock of Geese. Tournefort relates that formerly, in the Isle of Chio, flocks of Red-legged Partridges were reared which allowed themselves to be driven about in exactly the same way; and Sonini speaks of two Red-legged Partridges which an inhabitant of 414 415 Aboukir had managed to tame. All these facts abundantly prove that, with a little patience, it would be possible to raise the Partridge to the dignity of a domestic farm-yard fowl.
The Partridge is highly esteemed by epicures; it is also the delight of the sportsman, because it lies well to dogs. On account of its abundance, especially of the Grey variety, this may be called the "favourite game" of the French empire. Partridge-shooting, moreover, is what is generally chosen for the education of the inexperienced shot; the dog, too, by its pursuit, acquires such sagacity that renders him a valuable assistant to the disciple of St. Hubert.
Let us now take a rapid glance at the various species of the Partridge. The Grey Partridge (Perdix cinerea) is the most common; it is very plentiful over the whole of Central Europe, the North of France, Belgium, Holland, and Great Britain. In these countries it frequents the cultivated districts, the vast plains covered with crops, and the artificial meadows, in all of which it lives and breeds. This bird is not altogether harmless to the pursuits of agriculture, as, after seed-time, it is not satisfied with the grain left on the surface, but digs out those that are growing. It also devours the young green shoots of corn, and attacks the ears when they come to maturity. Its increase on a large scale might, therefore, produce serious mischief, which would hardly be compensated for by the services which it renders in destroying worms, insects, and grubs.
The Grey Partridge furnishes a variety of smaller size, the Migratory Partridge, which is not known in England. It is remarkable for its vagrant character, and forms a singular contrast to the stay-at-home habits of the genus generally. It makes its appearance in large flocks at the most diverse seasons and in the most varied latitudes. Not migratory in the proper sense of the word, its journeys seem undertaken under the influence of some unknown cause, and are wanting in regularity and constancy. It does not always follow the same route, and its journeys are intermittent. This bird is of a very shy nature, and is frequently met with in the East (Turkey, Syria, and Egypt); it is sometimes noticed in France, where it is called the Damascus Partridge. 416

Contrary to the Grey Partridge, the Red-legged, and those allied to it, have the tarsi provided with tubercles.
The Red-legged or Guernsey Partridge owes its name to the predominant colour of its plumage, and also to the pink shade of its beak, tarsi, and feet. Uncultivated wastes, thinly covered with heath, and undulating uplands adapted to the vine, are its favourite resorts. In France it is principally found in the south; in the northern departments it is not so plentiful as the Common Grey Partridge. It is also a native of Spain and Italy, and is very common in portions of Asia and Africa.
The brush-clad mountains are its home, and in fine weather it ventures even as far as the regions of perpetual snow. It is very fond of grapes and the edible variety of snails. In some parts of France it is scarce; the Jura, the Upper and Lower Alps, the mountains of Auvergne, and the Pyrenees are the districts where it is most abundant. In Greece, Turkey, and Asia Minor it is more plentiful.
Another variety, the Rock Partridge, or Gambra, which differs but little from the Red-legged Partridge, is almost unknown in France. Its habitat is Spain, Corsica, Sicily, and Calabria.
The Colin, Virginian or American Partridge (Ortyx virginianus, Wilson), has a thick and convex beak, smooth tarsi, and a longer tail than the Partridge. These characteristics would hardly entitle us to make any difference as to genus, if a study of their habits had not revealed certain details which justify us in doing so.
When these birds are flushed, they do not all of them fly towards the same spot, but disperse in every direction, and conceal themselves in the brushwood or trees. Under such circumstances, if one can only manage to re-find them, all may be killed in succession. They are more prolific than the Partridge, also less suspicious, and will readily enter snares set for them.
These birds are in the habit of making arrangements for sleeping which are peculiar, to say the least. All the individuals of the same flock begin by placing themselves in a circle at a certain distance from each other; then they all walk backwards, converging towards a common centre, until they are close to one another, side to side: in this position they pass the night. By 418 means of this precaution the whole flock can see in all directions, and fly away at once in case of danger, without one interfering with the other. Each bird, in fact, has a clear space in front of him, and runs no risk of being impeded by his companions when desirous of taking flight.
The Colin is also distinguished from the Partridge by its vagrant habits. In this respect it resembles the Quail, but its peregrinations are irregular, and do not embrace anything like the same extent of range. This bird is a native of North America, where it abounds. It exists in some districts of the United States to such an extent that, during one winter, in a circuit of not more than five or six leagues in extent, as many as twelve thousand head have been killed, without any apparent diminution of the species in the ensuing spring.
Having been brought to England and looked after, the Virginian has bred. Similar attempts have been made in France, but with less success, owing to a want of perseverance. The Colin would be an excellent addition to our game birds, as its flesh is delicate, and it lies well before pointers or setters.
The Californian Colin (Fig. 168), familiarly known as the Californian Quail, is a beautiful bird, adorned with a crest, the upper portion of which points forward. They are only found on the 419 Pacific slopes of the Rocky Mountains. On the high grounds which form the margin of the valley of the Sacramento River they are extremely numerous.
Another variety of Colin, figured by Audubon, is also a resident of California, where it is called the Solitary Partridge.
Francolins are distinguished from Partridges by a stronger and more elongated bill, by a more largely developed tail, and by the existence, in the male, of one or two sharp spurs. They also differ in their habits, for they frequent wooded and marshy districts, where they subsist on berries, seeds, worms, insects, and young bulbous plants. When not feeding, they are almost constantly perched on trees, where they pass the night. These peculiarities excepted, they bear a strong resemblance to the Partridge. Their flesh is highly esteemed, the Francolin taking the first place among our game birds.
A beautiful variety of Francolin is found in the South of China. Its favourite haunt is among the dwarf palmetto on the hill-sides. It lies well to dogs, but is so quick in flushing, and so rapid in flight, that even the best shots miss them. They are quite as large as the Grey Partridge.
Unfortunately, in Europe the Francolin is tending towards 420 extinction, for its wild nature prevents it accommodating itself to a restricted range. It is found on the southern coasts of the Black Sea, in Sicily, and the island of Cyprus. There are other species inhabiting Africa and India.
The Coturnix is closely allied to the Quail; the only physical distinction between them is the absence of the back toe. It frequents sandy districts and plains covered with high grass. It runs very swiftly, and but rarely flies. Should it be compelled, however, to do so, its course is seldom more than one or two yards above the ground, and of very short duration. Dropping, it then stubbornly persists in remaining on the ground, and prefers being caught to making a fresh attempt on the wing. Its flesh is excellent.
A European species, the Turnix tachydroma (rapid runner), (Fig. 169), inhabits Sicily, the South of Spain, and the North of Africa.
The Sunda Isles produce a species of Quail, the warlike instincts of which furnish an amusement for the barbarous tastes of the inhabitants, who regularly pit them one against the other, betting largely on the result, just as the English used to do on cock-fights.
All the birds of this family belong to South America. They are the representatives of the Partridge on that continent. Their essential characteristics are—a slender and medium-sized beak; tarsi rather long, and provided with nodosities; the back toe either very short or altogether wanting—at all events, no use in walking can be made of it from its elevated position; the wings and tail short, the latter sometimes deficient.
This family comprises four genera, all very closely allied to one another; these are the Tinamus, the Nothures, the Rhyncotes, and the Eudromes. We shall confine our remarks to their nature and characteristics.
These birds are naturally stupid, and cannot habituate themselves to captivity. They live in small flocks, except during the breeding season. They fly heavily, always in a straight line, but are swift runners. Some species manifest such sluggishness 421 that they will remain the entire day without moving, and will not even take the trouble to escape from their enemies. They have the habit of rolling themselves in the dust, and frequent indifferently cultivated ground, grassy meadows, or thick woods. Except in rare instances, they roost upon the ground. They are crepuscular—that is, they seek their food in the early mornings and evenings, and even by moonlight. Their selection of nutriment is frugivorous, granivorous, insectivorous, and vermivorous. They make their nests on the ground, and lay twice a year seven or eight eggs. Their flesh is good, and much sought after.
Tinamus tataupa (Swainson) may be taken as a representative of the order. Mr. Darwin, in his "Journal of Researches in the Countries visited by H.M.S. Beagle," describes this bird.
The birds belonging to this family are characterised by a short, crooked, and stout bill, long and pointed wings, a middling-sized tail, and a merely rudimentary back toe. The size of the Chionides varies between the Partridge and the Pigeon. The species of Chionis, Tinochore, and Attagis are included in this family.
The Chionides are remarkable for their marine habits; they frequent the sea-beach, and feed on sea-weed and animal remains. They are to be found in all southern countries. The Tinochores and the Attagis are natives of Chili and Paraguay: their habits are not known.
The distinctive features of this family are as follows: the bill straight and slender; the tarsi long and stout; the feet tetradachylous, and furnished with long and strong claws. This family comprises three genera: the Megapodius, Alecthelia, and Talegallus.
The Megapodii are but little known. All that has been ascertained is, that they inhabit marshy localities, fly but little, and run like Partridges. They lay each of their eggs in a separate hole, and leave them to be hatched by the heat of the sun. The young birds are able to dispense with maternal assistance and to provide for their own wants on leaving the shell. These birds inhabit the isles of the Pacific Ocean. 422
The Alectheliæ bear a great resemblance to the Megapodii, and are natives of the same places: their habits have not been studied as yet.
The Talegalli, or Tavons, inhabit Australia and New Guinea. They live in low brushwood adjacent to the sea. These birds have a curious plan in building their nests. They scrape together a large quantity of dry leaves, of which they form a conical mound five or six feet high. On the top of this heap they make a hole, in which the female drops two or three eggs, one on the top of the other. The heat produced by fermentation, joined with the rays of the sun, gives sufficient warmth to hatch them.
This family is divided into several genera or tribes; namely, Pheasants, Peacocks, Pintados, Turkeys, and Alectors.
The Pheasant tribe comprises not only Pheasants proper, but also the Domestic Fowls, the Argus, Tragopans, Roulouls, &c. Their characteristics are as follows:—The head bare; bill stout; wings short and flight heavy; tail largely developed; plumage extremely brilliant, and sometimes splendid.
All these birds were originally natives of Asia; some have been naturalised over nearly the whole face of the earth since time immemorial; the Pheasant, however, is not so widely spread, although its range has been much increased.
The Pheasant is remarkable for the extraordinary length of its tail, the middle feathers of which in one species, Reeves's Pheasant (Lyramaticus Reevesii), sometimes attain a length of seven or eight feet. It is a bird of slender make, of an elegant form, and the males are adorned with brilliant plumage; but the hens wear a much more unpretending attire. The sides of the face, and round the eyes, are bare and tuberculous. The stronger sex are provided with spurs.
There are many species of Pheasant, but there is no obvious difference in their habits. We shall, therefore, content ourselves with giving an account of the Common Pheasant (Fig. 170), which is the species most widely spread through Europe.
The introduction of the Pheasant into Europe dates at a very early age, if it is true that it goes back to the expedition of the 423 Argonauts, about 1300 B.C. The companions of Jason met with this bird on the banks of the Phasis, in Colchis, whence its name is derived. Struck with its beauty, they carried it back with them into Greece, whence it gradually spread over a large portion of the European continent. The Greeks, believing it to be indigenous to the banks of the Caucasian River, called it the "Bird of Phasis;" subsequently, however, it was ascertained that it also inhabited the whole of the South of Asia (China, Cochin-China, Bengal, &c.).
At the present day this bird is found in France, Great Britain, Holland, Germany, and even Sweden.
Pheasants prefer wooded slopes or marshy plains. Their food is of a varied character, and is composed of grain, berries, worms, insects, and snails. They are shy and timid in their nature, taking flight at the slightest indication of danger. They live in solitude up to the breeding season, when the male birds select their 424 425 mates, for they are polygamous. On these occasions they engage in such desperate conflicts that the weaker bird is often killed.
The hen Pheasant makes her nest on the ground, in the midst of some dense thicket, and lays from twelve to twenty eggs, which require twenty-four days to hatch.
The mother does not manifest that care and solicitude for her young which are so marked in the majority of other birds; she does not even specially recognise her own progeny, for she pays equal attention to all the young of her race that surround her. We must not, however, expect to find much maternal love in a bird which does not shrink from breaking her own eggs to gratify an unnatural appetite.
The Pheasant is not remarkable for its intelligence, for, in spite of its suspicious nature, it falls an easy victim to the poacher.
Pheasants, although they breed in a wild state in our climate, are principally raised in vast enclosures called pheasantries, where all the necessaries to existence are provided for them. As the females are bad mothers, it is no unusual thing for their eggs to be hatched by Domestic Fowls. During the first two months of existence the young Pheasants require the greatest care, for they are predisposed to numerous maladies. Their favourite food is ants' eggs.
The flesh of the mature is very savoury, but rather dry, and epicures consider that it ought not to be eaten till hung a long time, when it is said to be "high," a requisite which by analogy has extended to other game. There is one very curious peculiarity common to certain birds belonging to the family of which we have been speaking, and which is especially remarkable in the Pheasants—it is that when old females become unfruitful they assume the plumage of males. It is said that young Pheasants undergo the same change when deprived of their reproductive organs.
The Golden Pheasant (Phasianus pictus), Fig. 171, and the Silver Pheasant (P. nychthemerus, Linn.), are two beautiful birds, originally from China and Japan, and now naturalised to Europe. The former, clothed in purple and gold, bears a golden-yellow tuft on its head; the black-and-white costume of the latter is not inferior in beauty to the preceding. Linnæus has named them 426 427 Nychthemerus (the night and the day). There are also the Ring-necked or Collared Pheasant, slightly different from the Common Pheasant, which for some years has propagated rapidly in France and England; Reeves's Pheasant (Phasianus veneratus, Temm.), indigenous to China, where it is rather rare, and very highly prized for the beauty of its plumage and the extraordinary length of its tail—it is said that the exportation of this bird is severely interdicted; and lastly, the beautiful Lady Amherst's Pheasant, so called because that lady brought two living specimens to Europe. "I pass thus some and of the best," as is said in Hernani, the French comedy.
The Argus (Argus giganteus, Temm.), Fig. 173, a bird with magnificent plumage, which inhabits the forests of Java and Sumatra, takes its place beside the Pheasants, from which it only differs in having the tarsi longer and unprovided with spurs, and by the extraordinary development of the secondary feathers of the wings in the male. The tail is large and round, and the two middle feathers are extremely long and quite straight. When paraded, as it struts round the female, spreading its wings and tail, this bird presents to the dazzled eye of the spectator two splendid bronze-coloured fans, upon which are sprinkled a profusion of ocellated markings much resembling eyes: it owes its name of Argus to these spots. In a state of quiescence the wings are folded on the sides, and attract little attention. Only in the male bird is the gorgeous display of colouring to be found. The Argus is very timid; its habits are little known.
The general characteristics of the Cock (Gallus) are as follows:—A middling-sized, curved, and strong beak; head surmounted by a fleshy, red, and denticulated crest, the lower jaw furnished with two hanging gills, equally red and fleshy; rather long tarsi, armed with sharp spurs; short, concave, and obtuse wings; tectiform tail, arched and falling in plumes, with very developed medium feathers; brilliant plumage, with metallic reflections. This description applies exclusively to male birds. Hens, more humble in their costume, are not gifted with these exterior advantages; their plumage is generally dull and without attraction, their straight and slightly-raised tails are limited to an ordinary proportion; their crest is reduced to the most simple excrescence, 428 429 and in certain species entirely disappears; lastly, their legs are without the murderous spur with which the male is armed. They are also smaller and less vociferous than the male.
The domestication of this family dates from ante-historic times, so that we can only raise conjectures as to the original country and species from which the numerous varieties sprang which we now find spread throughout the world. The species, however, is probably one of those now living in a wild state in the islands of the Indian Archipelago. They may perhaps constitute some of the types which have given birth to our principal domestic races, and which are separated into a number of varieties.
Whatever may be the opinion adopted, we know that amongst the species indigenous to Asia are the Bankiva Cock (Gallus Bankiva, Linn.), which so nearly resembles our village Chanticleer as to be often confused with it;—the bird, known as Jungle-fowl by Indian sportsmen, inhabits Java, Sumatra, the Philippines, and Hindostan: it is sometimes called Sonnerat's Cock (Gallus Sonneratii, Latham);—the Bronzed Cock (Gallus æneus, Temm.), the Fork-tailed Cock (Gallus furcatus, Temm.), and the Giant Cock, or Kulm Cock (Gallus giganteus, Jardine), the largest species known. These are considered, not without reason, the founders of our most extensive races. The last mentioned lives both in a wild and domestic state in Java, Sumatra, and India proper. The Negro Cock offers a very remarkable case of contrast, for the crest, gills, epidermis, periosteum, and feathers of this species are black, but the flesh is white. The Negro Cock, very largely spread over Belgium and Germany, still lives in freedom in the Indies. All these species inhabit thick forests, and their manners are entirely unknown. Consequently, without further delay, we arrive at the description of the Domestic Cock.
The Cock is thick-set and massive, but without heaviness. His upright and bold walk denotes his pride. Without being an habitual runner, he moves with rapidity, but when driven to use his wings his incapacity reveals itself; it is with difficulty he raises himself from the ground, as if nature had destined him to live always by the side of man, attached to the earth which feeds them both. The Cock is a perfect model of a sultan; he attaches an entire seraglio to his train. His love is a 430 curious mixture of delicate attentions and revolting brutalities. See him walking in the midst of his companions, he assumes an air at once proud and defiant. He directs his wives, protects them, watches them with restless tenderness, and if he finds a savoury morsel he unselfishly parts with it. When the time for feeding comes, he softens his voice to invite them to come and peck up the grain spread upon the ground; again, he is cruel and brutal both to Hens and chickens. Of an ardent character, the Cock cannot suffer a rival at his side; thus battles are inevitable when two Cocks inhabit the same poultry-yard. With flashing eyes, head lowered, and feathers of the neck bristled, the two adversaries observe each other for a time in silence. At last the storm breaks with violence; they precipitate themselves upon each other, and fearlessly fight with both beak and spurs till the earth is reddened with their blood. These battles, which sometimes last an hour, only cease to recommence the next day, or till one of the champions succumbs, acknowledging 431 the supremacy of the victor, and abandoning the place. The Cock sometimes employs his courage and strength in more noble contests, for he does not fear to expose his life for the defence of the poultry-yard. Man, who knows how to utilise even the bad instincts of animals, has not failed to employ the natural combativeness of the Cock in ministering to his pleasures. In olden times the Greeks delighted in cock-fights; the Cocks of Rhodes were particularly renowned for their game qualities. It is related that Themistocles, marching against the Persians, who had invaded Greece, and seeing the troops discouraged before the battle, recalled to them the obstinacy Cocks displayed in their combats, and then added, "These animals display their courage for the single pleasure of victory; but you, soldiers! you go to fight for your gods, for the tombs of your fathers, for your children, for your freedom." These words reanimated the failing ardour of the Greek troops, and the Persians were vanquished. In memory of this event the Athenians consecrated a special day in the year to cock-fighting. The Romans borrowed this pastime from the Greeks. Even in the present day cock-fighting is still in favour in various parts of the East. In Java, Sumatra, and Manilla this amusement is carried to the length of folly. The inhabitants of these countries scarcely ever travel without a favourite Cock, which they carry under their arm. It is by no means rare to find gamblers betting not only their fortune, but even their wives or daughters, upon the strength and dexterity of a champion bird. In England the barbarous practice of cock-fighting in former days was a favourite pastime, nor is it now entirely abandoned. Henry VIII., we read, instituted rules for this then popular sport. From his example most of the English kings patronised it. Charles II. and James II. took it under their special protection. At that time cock-fighting was almost a science, which had voluminous codes, laws, and regulations, determining the circumstances of the combat, and settling the interests of betters. Now, however, it is almost exclusively confined to a few of the lower classes, the matches generally taking place on one or other of the few holidays which the hard-working mechanics have at their disposal. On these occasions the crowd gathers, the bets are arranged, 432 433 which sometimes rise to considerable sums. The spectators contemplate with barbarous pleasure the result of the anticipated combat, as both adversaries, armed with artificial spurs of pointed steel, are placed in the cock-pit. When left to themselves, they attack each other furiously, using their steel spurs with great adroitness (Fig. 175). The fight only terminates by the death of one of the combatants, and the victor is exhibited in triumph to the crowd. But his triumph is of short duration; the late hero called again to do battle, the spur of a more powerful adversary strikes a vital part, and he in his turn expires in the arena. The victor upon whom formerly so much interest rested, who excited so much admiration and such enthusiastic praises, is now in turn defeated—the former favourite of Fortune is deserted by the fickle goddess. In the meantime the other birds are ceaselessly heard crowing defiance, and proclaiming their eagerness for the fray. In the poultry-yard the Game Cock is quarrelsome, and even cruel; but this may be said of poultry generally. If one of their companions is sick or wounded, they unite to put an end at once to his sufferings and life. A stranger in the yard is certain to meet with a bad reception; the others set on it in a body, and only cease hostilities at the end of several days, or in the case of the Cock, who is their lord and master, taking the new arrival under his protection. Hens feed on anything that comes in their way; this renders them valuable to country-people, for they yield a profit without occasioning more expense than that of a few handfuls of corn in the morning and evening. Grain, herbs, worms, insects, carrion, rubbish of all kinds, are alike acceptable to them.
In France Hens begin to have eggs towards the month of February, and cease about the beginning of autumn, when they moult. By giving them heating food, they can be made to lay even in winter. They generally produce an egg daily—sometimes, but rarely, two. Pairing exercises no influence in this respect; that is to say, Hens have eggs without a Cock, but these are clear or unfruitful, and can only be used for food. The cry of the Hen when about to lay is well known. When she has produced about twenty eggs a desire to sit is manifested: if this is permitted, twelve or fifteen eggs, placed in a basket filled with straw, are given her; 434 when, uttering a peculiar clucking and spreading her wings, she sits upon her treasures, and covers them with so much perseverance as sometimes to forget to eat or drink, unless food is brought her. During twenty-one days the eggs are maintained at a uniform temperature of about 40° Centigrade. At the end of that time the young chickens burst their shell. The Hen fulfils the duties of a mother with incomparable devotion and tenderness; she follows her young brood step by step, calls them to her when they stray, and seeks nourishment for them, thinking little of her own wants till theirs are satisfied. Against all aggressors, with every feather bristling and angry eyes, she warns them, protects them, and defends them. If a bird of prey appears, she hastens to meet it, and assumes such a menacing attitude, that few will not immediately take to flight. The chickens develop rapidly. At the end of a month the crest of the males shows itself; at six months they have acquired the vigour necessary for reproduction; females begin to lay about the same time. At the age of three months transforming them into capons and pullets is performed—names given to those individuals which have been deprived of the sexual organs. In this condition they are fattened, and acquire a superior flavour and delicacy of flesh. Pullets and capons, in losing the generative faculty, lose also the inherent characteristics of their sex. The temper of the male becomes so mild that he has been made to perform maternal duties when a Hen has deserted her chickens to recommence laying, by plucking out feathers from his stomach, and then rubbing the part with nettles; the chickens gliding under, allay the pain which the stings have caused, and thus the bird derives pleasure from his wards, and soon attaches himself to them. The departments of Sarthe and Ain are celebrated for the pullets there raised.
Hatching is sometimes performed by artificial incubation. In olden times the Egyptians had recourse to this means to increase the production of poultry. The method which was used, and which is still employed in modern Egypt, consists in placing the eggs in a furnace maintained for twenty-one days at a uniform temperature of 40° C. By this means a hundred millions of Fowls are annually produced in Egypt. Simple as this operation appears, it is not without difficulty, or the climate of Africa assists, for 435 attempts in France have never been crowned with success. In the Sunda Islands artificial incubation is accomplished in another manner: here men are found who, for a small salary, remain for three weeks stretched out and immovable upon eggs placed in ashes. Antiquity has bequeathed to us the story of a curious incubation made at Rome by the Empress Livia. This lady being pregnant, and desiring a son, thought of hatching an egg in her bosom, and drawing a prognostic from the sex of the chicken. The operation succeeded—the egg having produced a Cock, the empress concluded that her wishes would be granted. These were realised, for she brought into the world Tiberius—rather a wicked bird, as every one knows.
The Tragopans (Ceriornis, Swainson) and the Jungle-fowls belong to India or the Indian Archipelago, and are all remarkable for the brilliancy of their plumage. The Houpiferes, or, as their name expresses, Tuft-bearers, strongly resemble our Domestic Fowl. The Tragopan, which Buffon calls the Horned Pheasant, looks like a cross between the Domestic Fowl and the Pheasant, but is distinguished by two small horns, which decorate the head of the male. Lastly, the Jungle-fowls live in a wild state, being as yet unknown domesticated, consequently little can be said of their habits, but they probably differ but slightly from those of the Pheasants.
Pintados (Guinea-fowls) have remarkably small heads for their size; beak and neck short; the tail equally short and drooping; the tarsus very low, and destitute of spurs; body round; wings short and concave; on the head is a hard crest of a reddish blue, sometimes replaced in mature birds by a tuft; the wattles are fleshy, and hang under the beak.
The Common Guinea-fowl (Fig. 176) has a slate-coloured plumage, covered with white spots; it is indigenous to Africa, and its introduction into Europe dates from far-distant times; it was known to the Greeks and Romans. The former made it an emblem of paternal affection. According to Greek writers, the sisters of Meleager felt such grief at the death of their brother, that Diana, to terminate their woes, changed them into Guinea-fowls. The goddess, wishing that their plumage should bear the trace of their tears, marked it with white spots. 436
The Romans, who highly esteemed the flesh of these birds, propagated them with the greatest care to figure at their feasts, but after the invasion of the barbarians they disappeared from Europe, and during the Middle Ages we never hear of them. The Portuguese re-discovered them in Africa on their return from the Indies, and again imported them into Europe, where they have since multiplied to a great extent. But the turbulent and quarrelsome character of these birds and their noisy and discordant cries are serious obstacles to their becoming favourites; they have also ceaseless quarrels with the Hens and Turkeys, their neighbours, and although not so strong as their antagonists, they fight them fearlessly. They have been seen to attack the young of other birds, and split their skulls with a blow of their beaks. They show great attachment to their own young, yet they occupy themselves but little with the cares of a family; consequently their progeny is generally brought up by Hens or Turkeys. Although bad nurses, their fecundity is very great, and when well fed they lay as many as a hundred eggs in a year: these are much sought after, and epicures prefer them to those of the Hen. Their flesh, though good, is not so much esteemed. There are now several species known in a wild state in Africa, and in a domestic 437 state in Europe. They are numerous in Arabia, where they are found in the neighbourhood of marshy places, in little bands composed of a male and several females. Transported into America after the discovery of that continent, the common variety is now perfectly acclimated there, and is even to be found wild in some of the vast forests and savannahs of that country.
Turkeys are birds of large size, easily distinguished from other Gallinacean fowls by the following characteristics:—Bare heads and necks, decorated with fleshy appendages—those of the neck, which fall under the head in front of the bird, are capable of being inflated and much enlarged under the influence of love or anger; a brush of long and straight hairs hangs at the base of the neck; the tarsi are strong, and provided with slightly-developed spurs; lastly, the tail is round, of moderate length, and at the will of the bird can be expanded like a fan.
The Turkey was originally imported from North America, where it still lives in a wild state; it is frequently met with in the forests which border the large western rivers of that country, such as the Mississippi, Missouri, and the Ohio, and it must be studied there to acquire a correct idea of its habits. The Domestic Turkey is not so handsome in plumage as is the Wild, but the former generally much exceeds the latter in size. The colour of the Wild Turkey is brown, mixed with blue and green, giving out a diaphanous metallic brilliancy. The full-grown male bird sometimes measures over three feet, and weighs from twenty to twenty-five pounds. The American naturalist, Audubon, speaks of having seen one which was upwards of thirty-six. The female is much smaller, and seldom exceeds ten pounds in weight: her plumage cannot vie with that of the male in splendour. Although it does not appear constructed for the purpose, the mature bird is capable of taking considerable flights, passing with ease in its wild state across such gigantic rivers as the Ohio, Mississippi, and Missouri, which in every direction traverse and bisect the middle portion of the great North American continent; but it, as a rule, only takes wing when all other means of locomotion are denied, for it runs with surprising rapidity, distancing the common cur dog with ease, and only abates its speed after a lengthened pursuit. It accomplishes long journeys on foot; not, however, 438 caused by atmospheric influence, but want of sustenance in the country which it inhabits. It is generally towards the beginning of October that these migrations commence. The Turkeys then unite in troops of from ten to a hundred individuals, and go towards the regions which they have chosen for their new abode; the males form a separate drove from the females, which march at their sides, surrounded by their young families. The necessity of protecting their young from the brutality of the old cocks, who will kill them if opportunity offers, inspires the hen Turkeys with this habit. It sometimes happens that the emigrating band are stopped by a water-course, when all evince great agitation by spreading their tails, uttering frequent gobbles, and yielding themselves to extravagant demonstrations. At the end of a day or two, after having inspected the neighbourhood, they mount upon the branches of some of the highest trees, and take to the wing to traverse the obstruction. Some of the young ones always fall into the water, but they know perfectly how to swim: when all have reached the opposite bank they run hither and thither as if they were mad, and from their recklessness at this time it is very easy to approach and kill them. These birds pair in February or March, according to latitude; the females produce eggs six weeks afterwards. At this time the hen secretes herself in a place unknown to the male, as he would break the eggs. The nest is an indentation in the ground, lined with soft grasses, moss, and dry leaves, and in it are deposited her embryo progeny, which are sat upon with perseverance deserving praise. In this respect they are superior to all Gallinaceous fowls, even surpassing the Domestic Hen. When the mothers leave their eggs to seek food they are always careful to cover them with leaves, the better to screen them from the sight of the Fox, Lynx, or Crow. The incubation lasts about thirty days. As the time for hatching approaches, no power can make the mother leave her nest, no peril will cause her to desert her charge. On being hatched, the young Turkeys, under the protecting care of the old bird, are led to sequestered feeding grounds, and do not leave her till the end of several months. Wild Turkeys have many formidable enemies, the most destructive being Man, next the Lynx and the Eagle Owl; they are, therefore, very distrustful, and when on the ground secrete 439 themselves at the least appearance of danger; but if perched upon a tree they are less guarded, and consequently can be more easily approached by the sportsman. On a misty, moonlight night American hunters take their posts under trees where Turkeys commonly perch. In this situation the game will receive several discharges without making the slightest attempt to escape, although numbers of them in succession may have been killed. It is difficult to explain this apparent apathy, especially when we know their hurry to fly before the Owl. It is doubtless owing to the want of sagacity which they manifest under these circumstances, as well as to their ludicrous aspect and eccentric attitudes, that Turkeys have 440 gained the reputation of stupidity. This bird, however, sometimes gives proofs of intelligence, as the following fact, related by Audubon, shows. He had raised a Wild Turkey from its most tender age, which had become extremely tame, but the love of independence remained very strong in the bird, for it could not accustom itself to the pent-up life of its domestic relations. Thus it enjoyed the greatest freedom; it went and came, passing nearly all its time in the woods, only returning to the house in the evening. At length it ceased to come back, and from that moment dispensed with visiting its birth-place. Some time after, Audubon, whilst hunting, perceived a superb Wild Turkey, upon which he set his dog; but, to his great surprise, the bird did not fly, and the dog, instead of seizing it when it was overtaken, stopped and turned his head towards his master: greater still was the hunter's surprise when, having approached, he discovered his ancient pensioner. This Turkey had recognised the dog, and understood that it would do him no harm, otherwise it would have scampered off immediately.
Turkeys feed upon herbs, grasses, fruits, and berries of every description; they are partial to beech and other nuts; and their liking for wheat and maize is such that they frequent the neighbourhood of cultivated fields, where they make the greatest ravages. They also occasionally feed upon insects, frogs, and lizards. The large destructive grub familiarly known as the Tobacco Worm they are particularly partial to, and are consequently much encouraged by the tobacco planters. In a domestic state they are even known to have killed and eaten rats. One curious peculiarity in the history of the Turkey is its horror of red; the sight of a scarlet object throws it into the most comical fury. It is needless for us to vaunt the flesh of the Domestic Turkey; every one is agreed on this subject. We will only say that, from the testimony of many travellers and naturalists, the flesh of a Wild Turkey, killed in winter or spring, before laying, is far superior to that of the Domestic bird, those coming from Southern Indiana and Illinois being considered by Americans as the finest. The Turkey, being indigenous to America, was naturally unknown to the ancients. The precise date of its introduction into France is not recorded. According to some, it was at the end of the fifteenth century; to others, 441 only at the commencement of the sixteenth. Anderson affirms that the first Turkeys raised and eaten in France were served at the marriage of Charles IX., in 1570.
The Honduras or Ocellated Turkey (Meleagris ocellata, Cuvier) is one of the most beautiful Gallinaceans; its plumage is magnificent; the tail is enamelled with large blue eyes, each of which is surrounded with a circle of brilliant yellow and purple. It inhabits the country surrounding the Bay of Honduras, Southern Mexico, and all Central America. At the Regent's Park Gardens, London, is to be seen a splendid hybrid, bred between the American Wild Turkey and the Honduras species.
The tribe of Peacocks comprehends the genera Pavo cristatus, Hist. Anim.; Pavo javanicus, Horsfield; and Lophophores. The feature which essentially distinguishes Peacocks from other Gallinaceans is the immense tail with which nature has endowed them. This tail, formed of long, large, and tufted feathers, coloured with the richest shades, is capable of being raised up like that of a Turkey. When one contemplates this magnificent appendage, in which purple and gold vie with the most varying colours of the emerald, and notices the innumerable and brilliant eyes with which it is studded—when with delight he views its lofty stature, elegant shape, noble carriage, and, above all, a slight and mobile tuft, the emblem of royalty, crowning its head—one cannot help being struck with lively admiration, and spontaneously according the palm of beauty to the privileged being which unites in itself so many marvels. The Peacock was known from the earliest time; for it is mentioned in the Bible as one of the most precious products brought from Asia by King Solomon's ships. It made its first appearance in Greece after Alexander's expedition into India. Alexander, it is said, was so astonished at the sight of this bird that he forbade it to be killed under the severest penalties. For a long time they were very rare, and fetched a high price at Athens, and the people from the neighbouring towns assembled in crowds to see them. From the Greeks they passed to the Romans; but this nation, more fond of the pleasures of the table than of spectacles, soon made them figure in their feasts. Peacocks consequently were rapidly propagated in the poultry-yards of the rich patricians; and some of the emperors, such as Vitellius 442 and Heliogabalus, caused dishes of the heads or brains of Peacocks to be served: from this cause their price became excessive in Rome. Little by little they spread throughout the empire, and thus the Peacock has become naturalised in Europe. During several centuries its exquisite and delicate flesh was in very great favour; but the importation of the Pheasant, and later that of the Turkey, brought successful rivals for table honours. The Peacock is now bred principally to please the eye; and even when it does make its appearance at some ceremonious repast, it is intended more to gratify the eye than the palate, for the carcass is invariably decorated with the resplendent tail, spread out in fan-shape. The Domestic Peacock, which is now the pride of our gardens and parks, is indigenous to India and the isles of the Eastern Archipelago. There they still live in large troops in the depths of the forests. They are so abundant in localities, that it is said the traveller, Colonel Williamson, being delayed one day in the district of Jungleterry, counted not less than from twelve to fifteen hundred. The Peacock runs with such rapidity that it often escapes from pursuing dogs; it takes to the wing with difficulty, and flies slowly, though it can prolong its flight to a considerable distance. It feeds upon grain of all kinds, which it swallows without crushing. In the evening, to roost for the night, it perches upon the limbs of the highest trees. In a state of domesticity it retains this fancy for elevated places, and takes pleasure in mounting on the roofs of houses, upon which it struts and excites itself, scattering tiles, or tearing up the thatch, as the case may be; for the devastating instinct appears to be very strongly developed in it when opportunity offers. This bird also commits great ravages in cultivated fields. The Peacock at times utters deafening cries, which contrast unpleasantly with its dazzling plumage—one wishes for a more harmonious voice with such a magnificent body; but what animal possesses all perfections? It is polygamous. At the commencement of the spring the male displays to the females all the splendour of his plumage; he struts, spreads his tail, delights at the sight of his own figure, and receives with pleasure the admiration which his charms draw forth. His vanity knows no bounds; the adulation of his females is not sufficient for him, he must have eulogiums from man also, 443 and before him rejoices to display all the riches of his wonderful tail. Complete master in the art of pleasing, he knows how to manage the transitions of light and shade so as to present himself to the greatest advantage; and when he has been gazed at sufficiently, by reiterated struts he marks his contentment. At the end of August his beautiful plumage falls off, not to come forth again till the spring. It is said that the Peacock is so ashamed of having lost that which was his pride, that he then shuns the sight of 444 man. This is better explained by the fact that the time of moulting is for this, as for all other birds, a period of sickness; they consequently retire into solitude, to find there the calm and tranquillity which their critical state demands. The Wild Peahen lays from twenty to thirty eggs in a hole hollowed out in the ground. She is much less fruitful in the Domestic state. She takes the greatest care to hide her nest from the searching eye of the male, which breaks the eggs whenever he finds them. Incubation lasts from twenty-seven to thirty days. The young follow their mother from their birth; at six months they are reputed adult, and attain their full development at three years. The Peahen, like the hen Pheasant and the Common Hen, adopts the plumage of the male when age has rendered her unfruitful, or when, by a premature atrophy, her eggs have become sterile. The Peacock lives from twenty-five to thirty years; some authors have wrongly attributed to them the longevity of a century.
The Polyplectrons (Diplectron, Vieillot) owe their name to the superabundance of spurs with which they are armed; the males always possess two, sometimes three. The plumage of these birds, like that of Peacocks, is sprinkled with glittering ocellations; but their tails are shorter, and not susceptible of expansion. There are three or four varieties known, which inhabit India, China, and the isles of Sumatra and Borneo. Their manners have not yet been studied.
Impeyan Pheasants are little better known than the Polyplectrons. They prefer cold climates, which sufficiently accounts for their predilection for the elevated ridges of the Himalayas. No one has as yet succeeded in acclimating them in Europe. This is one of the most brilliant Gallinaceans; its plumage, bedizened with the most lively colours, has gained for it in India a very significant name—that of the "Golden Bird."
Under the name of Alectors (from the Greek αλεκτωρ), Cuvier has united a certain number of American birds bearing some resemblance to the Cock, and has divided them into several varieties: the Hoccos, Pauxis, Penelopes, Parraquas, and Hoazins.
Hoccos are analogous in form and size to Turkeys, of which they are the representatives in their habitat, Central America, Guiana, and Brazil. Deprived of spurs, they have a large tuft 445 upon the head, formed of distorted and erectile feathers. They live in numerous troops in the midst of forests, and feed upon seeds, berries, and buds. Naturally very gentle, they readily yield to captivity, when they become familiar, and evince pleasure in 446 the caresses of their masters. Sonnini relates that he has seen them wander at liberty through the streets of Cayenne, return to their homes without hesitation, and leap upon the tables to take their food. Their flesh is exquisite, and in all respects worthy of the favour of epicures. These different qualities should cause an honourable place to be assigned to Hoccos in our poultry-yards; it is, therefore, to be regretted that the attempt to acclimate these birds made by the Empress Josephine, at the commencement of this century, have not been renewed.
Galeated Curassows, or Pauxis (Ourax pauxi, Cuv.), differ but little physically from the Hoccos. They have the same habits and characteristics, and easily habituate themselves to servitude.
Guans or Penelopes (Penelope cristata, Gmelin), and Parraquas (Latham), are two genera of birds strongly resembling each other; they have an analogy to Pheasants, but only on account of their general forms; in short, they possess the confiding and peaceable nature of Hoccos and Pauxis, and easily submit to the domination of man. Their flesh is delicious; they also deserve to be acclimated.
The Hoazins (Opisthocomus cristatus, Quoy and Gaimard) inhabit the savannahs of Guyana. Their flesh, which exhales a strong odour—due, no doubt, to the vegetables on which they feed exclusively—is far from being agreeable.
The Columbidæ family establish a transition between real Gallinaceans and Passerines; in short, they partake of the nature of both. Whilst they approach the former in their anatomical and purely material characteristics, such as the structure of their beaks, sternum, and crops, they resemble the latter in their elegant forms, peaceable manners, and in all their habits.
Like the Passerines, they are monogamists. The male and female build their nests together, and share the cares of the incubation and education of their young; these, when born, are blind, and only covered with a slight down, and are quite unable to run like young Gallinaceans. There are generally two Pigeons hatched at the 447 same time; and it is a very curious fact that there is almost always a male and a female. They do not quit the nest till they have acquired sufficient strength to use their wings and fly. During the earliest portion of their existence they receive no other nourishment from their parents than a sort of pap secreted in the walls of the gullet; but at the end of some days the father or mother discharges into their beaks the food which they themselves take. When they are sufficiently developed, they travel with the adults in large flocks to seek a milder climate or better feeding ground: their migrations in the natural state occur in spring and autumn. What distinguishes them from the true Gallinaceans is that they have a thumb inserted even with the other toes, and that consequently they are able to perch; almost all Pigeons pass much of their lives on trees. Their food consists principally of seeds, berries, and fruits, sometimes insects, and a peculiar little snail similar to that found in the Isle of France. Their flesh, generally good, in some species, such as the Crowned Goura, acquires an exquisite flavour. Thus they form an immense part in public alimentation, both in a domestic and wild state. They are shot very extensively at the time of their migration. Although their flight is noisy, and even presents some appearance of heaviness, it is easy and sustained, so that Pigeons have been known to accomplish journeys of surprising length in a few hours.
We will divide the Pigeons into three families—the Colombi-Gallines, the Colombes, or, properly speaking, Pigeons, and the Colombars.
A certain number of birds rank in this family, which, with the general forms of Pigeons, still preserve the habits of Gallinaceans; hence the mixed name of Colombi-Gallines. Thus they constantly live on the earth, build their nests there, and only take refuge upon trees to pass the night or escape from danger. They run perfectly, but fly badly, and are sedentary; lastly, some species have cephalic nudities and fleshy appendages, or long, movable feathers round the neck like the male of the Domestic Fowl. Physically they are characterised by a slight and straight beak, 448 and by rather high tarsi. This family comprises a very large number of species spread throughout Central and South America, the isles of the Indian Ocean, and a great part of Africa. The compass of this work will not permit us to examine all: we will merely mention the most remarkable, the Great Crowned Pigeon (Columba coronata, Latham), very common in New Guinea and the Moluccas. The plumage of this bird is of a beautiful greyish blue; its head is ornamented with a pretty plume of straight, long, and tapering feathers; it is about the size of a Domestic Fowl, and very highly esteemed for the qualities of its flesh; consequently the inhabitants of the above islands raise it in their poultry-yards (Fig. 181).
Colombes have slender beaks, long wings, and short tarsi. The principal species are the Wood Pigeons, Common Domestic Pigeons, Carriers, Turtle Doves, and Passenger Pigeons: the first three are indigenous to Europe.
The Wood Pigeons (Columba Œnas, Selby), Fig. 182, are the largest species of this family; their plumage is slaty grey, 449 with bluish, green, and rose-coloured reflections. They are spread throughout all Europe, but chiefly in warm and temperate parts. They are very common in France, where they arrive in numerous flocks early in March, generally departing in October or November to pass the winter in more hospitable climates. At the time of their passage the Alpine and Pyrenean hunters destroy them in large quantities. The Wood Pigeons or Cushats inhabit forests, and delight among the branches of large trees. They feed upon acorns and beech-nuts, and are very partial to cherries and strawberries. With the farmers this bird is far from a favourite, for its appetite is insatiable, and it is alike destructive to grain in the ear or germinating. They build their nests in lofty trees. The female, after having chosen a place, forms the nest out of materials which the male brings her, such as little dead branches which it detaches from trees by the aid of its feet or beak; it never picks up the boughs which strew the ground. This nest is but a rude shelter, scarcely large enough to contain the young, and sometimes falls to pieces before they are able to fly; in this case the brood retains, if possible, a position on the large branches which supported their previous dwelling. Queests, as they are frequently called, generally lay in March and August. Incubation lasts twelve days, and the young can take flight about two weeks afterwards. During all the time of the incubation and education of the young the male remains near the female, constantly cooing, as if to break the monotony of her occupation. In the wild state Ring Pigeons are distrustful and difficult of approach, but their characters become modified by domestication, or even by an independent life passed in the neighbourhood of man. Thus young ones taken from their birth familiarise themselves without difficulty, and do not appear to regret having lost their liberty. They do not breed in this condition—or 450 at least we do not know how to make them do so; it is said that the ancients understood this art.
Ring Pigeons are seen in Paris which have from time immemorial chosen a domicile in the gardens of the Tuileries, at the Luxembourg, and in the Champs Elysées. They are very tame, and come almost under the feet of promenaders. Few inhabitants of Paris have not seen at the Tuileries the charming spectacle of an old man who attracts round him numbers of Wood Pigeons and Sparrows, to which he distributes crumbs of bread. The confidence they show to this kind friend as an acknowledgment of his goodness is wonderful; they rest upon his shoulders, take the bread from between his fingers, and even from his mouth, and allow themselves to be caressed without manifesting the least fright: this is evidence of the possibility of taming Ring Pigeons.
Wood Pigeons (Columba Œnas) have many traits of resemblance to Ring Pigeons, but they are smaller, justifying the name of Little Queest which is sometimes given to them; their habits are the same as those of the preceding species, except that they build their nests in the hollows of trees, instead of upon the branches, as the former species do. They are very plentiful in the South of Europe and in Africa. They leave France regularly in the month of October.
Wild Rock Pigeons (Columba livia, Selby) delight in rocky and arid places. They depose their two eggs in the clefts of rocks and ruins. They are seldom seen in Europe in a state of complete liberty, except upon some parts of the coasts of England and Norway and certain isles of the Mediterranean. They willingly sacrifice their independence to live in pigeon-houses. They are generally regarded as the founders of the numerous races of our Domestic Pigeons.
Domestic Pigeons probably sprang from the Wild Rock Pigeons. They are of two kinds—the Colombier Pigeons and the Aviary Pigeons. The former enjoy almost complete liberty; they traverse the country all day to seek for food, and sometimes even return to a wild state. The latter are quite tame, and the door of their habitation can be left open without danger; they go a little distance, and always return to their domicile. If Domestic 451 Pigeons cause some harm to our crops, they amply compensate for these devastations by the services which they render to agriculture. They are equally valuable to the breeder and consumer; the former derive a certain profit from them, and the latter an agreeable and economical article of food. To give a sufficient idea of the resources which they supply to public alimentation, we have only to state that certain species lay as many as ten eggs a year. Further, they supply a manure which is very efficacious for some soils. Raising Pigeons necessitates certain precautions which cannot be neglected without bad results: the greatest cleanliness is necessary in the pigeon-house or aviary; all turbulent individuals which sow discord, and often injure the fecundity of females, must be excluded; and the races must be separated as much as possible the one from the other, in order to avoid the production of sterile varieties. Amongst the Domestic species the naturalist can study at leisure the manners of Pigeons, and form an exact idea of their natures and inclinations; for he can observe them from their first steps, making their early timid endeavours to raise themselves in the air; afterwards noting at more mature age the evolutions of the sexes, and their fidelity to each other through years after pairing. We will examine rapidly the principal races of Domestic Pigeons.
The first is, as we have said, the Common House Pigeon, differing slightly from the Wild, which almost exclusively supports the population of Pigeon-breeders; this is sometimes called the Fugitive Pigeon. The Blue Rock is only a modification of the Wild Rock Pigeon; in form it is, however, more elegant, while the plumage is prettier. It is one of the most fruitful species.
The Pouter Pigeon owes its name to the faculty which it possesses of inflating its crop to an immense size by the introduction of air. This peculiarity often destroys them; indeed, when feeding their young, they find so much difficulty in causing the seeds which they have swallowed to reascend into their beaks, that they contract a malady which is frequently fatal.
The Roman Pigeons, thus named because they are very common in Italy, are easily recognised from the circle of red which surrounds their eyes. 452
The Swift Pigeon is of small size, its flight is light and rapid, and its fecundity very great.
The Carrier Pigeons belong to this race. They are celebrated for their attachment to their birth-place, or to the spot that contains their offspring, and for the intelligence which enables them to regain their native countries from whatever distance. Transport them miles from their homes, even in a well-closed basket, then give them their liberty, and after a time they will return, without the slightest hesitation, to the place from which they were taken. This valuable faculty has long been utilised, especially in the East. The Romans made use of Pigeons as messengers. Pliny says that this means was employed by Brutus and Hirtius to concert together during the siege of a town by Marc Antony. At the siege of Leyden, in 1574, the Prince of Orange employed Carrier Pigeons to carry on a correspondence with the besieged town, which he succeeded in freeing. The Prince, to mark his acknowledgment of the services rendered by these sagacious birds, wished them to be fed with strawberries, and their bodies to be embalmed after death. We learn from Pierre Belon, the naturalist, that in his time navigators from Egypt and Cyprus took Pigeons upon their galleys, and liberated them when they had arrived at the port of destination, in order to announce to their families their safe journey. In our century they have been made use of for similar purposes. The fluctuations of the Bourse were for a long time sent from Paris to Brussels by means of Carrier Pigeons.
The Tumbler Pigeon owes its name to its curious manner of flying. It has a habit, after it has risen to a certain height, of throwing five or six somersaults.
The Wheeling Pigeon describes circles like birds of prey. It is turbulent, and ought to be banished from pigeon-houses.
The Nun Pigeon is recognised by a kind of hood formed of raised feathers, which covers the back of the head and neck, and to which it owes its name. It flies heavily, but is very familiar and very prolific.
The Fan-tailed Pigeon is remarkable for its tail, which is very large, and raised like that of the Peacock, and for the convulsive 453 trembling which agitates it, especially at breeding-time. It thrives badly in an aviary, and is little valued, except as an object of curiosity.
There are two species of Doves—the Turtle Dove (Turtur communis, Linn.) and the Ring Dove (Turtur risorius, Selby). The former is the smallest species of the family of Colombidæ. They are found throughout Europe, but are more abundant in the south than the north. They arrive in France in spring, and depart for warmer countries at the end of summer. They build their nests in large trees in the shady and most retired parts of woods. They feed on seeds and berries. After harvest they visit stubbles of wheat or other grain; the abundant nourishment which they there find makes their flesh extremely delicate and nutritious. Although naturally wild, the Turtle Dove is easily tamed when taken young, when it evinces great attachment.
The Ring Dove is indigenous to Africa, where it lives in a state of freedom. This is the species which, in Europe, is raised in cages and aviaries. In certain towns of Egypt, particularly Alexandria and Cairo, they are so tame that they walk in the streets, and even enter houses, fearless of the presence of occupants. They are prolific, for they lay every month, except during the moulting season. Their cooing somewhat resembles a laugh—hence the name of Laughing Dove which has been given them. The ancients made the Turtle Dove an emblem of tenderness. This honour is justified by the kind attention which the male shows the female, especially during the period of incubation.
The Passenger Pigeon (Fig. 183) is the Columba migratoria of many authors: it inhabits North America. They are remarkable for the strength and rapidity of their flight, and for the migrations which they accomplish.
The American naturalist, Audubon, says, "Pigeons have been killed in the neighbourhood of New York, having their crops still full of rice, which they could not have taken nearer than the fields of Georgia and Carolina—six or seven hundred miles distant. As their digestion is sufficiently rapid to entirely decompose grain in the space of twelve hours, it follows that they must have travelled the above space at the rate of a mile a 454 minute. One of these birds, if able to keep up this velocity, could visit the European continent in less than three days."
It is not for the purpose of seeking a warmer climate that they undertake their journeys, but to procure food when the acorns become scarce in the woods which they inhabit. Their migrations, consequently, are irregular as to date. Looking at the innumerable and closely-packed masses of Passenger Pigeons which take part in these voyages confuses the mind. Audubon one day endeavoured to count the flocks which passed above him in one hour. He counted a hundred and sixty-three in twenty minutes, but he was soon obliged to give up, the flights succeeded each other so rapidly. He says: "The more I advanced, the more Pigeons I met. The air was literally filled with them. The daylight, in full mid-day, was obscured as by an eclipse; the dung fell like flakes in a fall of snow; the buzzing of their wings stunned me, and gave me a sleepy sensation." These Pigeons are 455 endowed with very strong sight. When flying at a considerable height they can perfectly distinguish the places which will furnish them with the means of subsistence. Having found a suitable country, they alight upon an immense space of ground, and in a few minutes completely ravage it. Large quantities of them can then be destroyed without any apparent diminution in their number. Some hours after their descent they again take to flight, and regain their nocturnal domicile, frequently twenty or thirty miles distant, where a frightful slaughter is often made amongst them. Long before the sun sets the inhabitants of surrounding counties await them with horses, carts, guns, and ammunition. Some even bring flocks of pigs, to fatten on the flesh of the Pigeons which the destroyers are unable to carry away. Audubon, who assisted at one of these slaughters, has related it as follows. He says:—"Every one holds himself in readiness, with eyes directed towards the heavens. Suddenly a general cry of 'They come!' resounds. The noise which they made, although at a distance, reminded me of a strong sea-breeze amongst the cordage of a ship, the sails of which are furled. When they passed above my head I felt a current of air which astonished me. Thousands were already struck down by men armed with poles, but they continued to arrive without intermission. Fires were lit, and it was then a fantastic sight full of frightful magnificence. The birds precipitated themselves in masses, and pitched where they could, one upon the other, in large heaps like barrels. Then the branches gave way under the weight, cracked and fell, bringing to the ground and crushing the closely-packed flocks which covered every part of the trees. It was a lamentable scene of tumult and confusion. In vain I tried to speak, or even to call the persons nearest to me. It was with difficulty that I could hear the guns fire, and I only perceived they had fired by seeing them reload their arms. Pigeons continued to come, and it was past midnight before I noticed any diminution in the number of the arrivals. The uproar continued all night. At last the day approached, the noise began to abate a little, and, long before we could distinguish objects, the Pigeons commenced to start in quite an opposite direction to that in which they had come in the evening. At sunrise all that were capable of flying had disappeared. 456 Now it was the Wolves' turn, the howls of which saluted our ears. Foxes, Lynxes, Cougars, Bears, Rats, Opossums, and Martins, bounding, running, climbing, pressed to the quarry, whilst Eagles and Falcons of different species flew down from the air to take their part of such rich booty. The sportsmen then, in their turn, entered into the midst of the dead, the dying, and the wounded. The Pigeons were piled in heaps, each took what he wished, and the Pigs were left to satiate themselves on the remainder."
These massacres are in nowise injurious to the existence of this species. In short, according to Audubon, the number of these Pigeons becomes doubled or quadrupled in a single year.
This family, established by Levaillant, comprises some species which belong entirely to the hot countries of Asia and Africa. These birds are characterised by thick, strong, bent beaks, which enable them to break the envelopes of the fruits which serve them for food. They fly less rapidly than birds of the Dove family, and coo in a different manner. They inhabit woods, and build in holes in trees. Their flesh is good. The principal species are found in Abyssinia, Senegal, and the Indian Archipelago. 457
People will be strangely mistaken if they imagine that all the birds which rank in this order possess the faculty of climbing. In reality it is only the privilege of some, and does not belong exclusively even to them, for it is found in some of the Passerines. The essential characteristic of the Climbers lies in this organic disposition—that the external toe, instead of being placed in front like that in other birds, is placed behind, by the side of the thumb. For this reason the denomination of Climbers has been substituted by that of Zygodactyles, which is used by Temminck, Vieillot, and others, and which has the advantage of perfectly expressing the distinctive characteristic of the order, for this word signifies fingers disposed in pairs. Thanks to the formation of their feet, the Climbers can clasp the branches of trees strongly; thus they are almost continually perched. Their flight is medium, being neither so powerful as that of the Raptores nor so light as that of the Passerines. These birds feed upon fruits or insects, according to the strength of their beaks. They chiefly inhabit warm countries, and their colours are generally brilliant. Lastly, they are all monogamists, with the exception of the Cuckoo. This order is one of the least numerous of the class of birds. It comprehends but few families, amongst which we will mention the Parrots, Toucans, Cuckoos, Woodpeckers, and Jacamars.
Parrots have large, strong, and round beaks; the upper mandible strongly hooked and sharp at the extremity, extending beyond the lower, which is rather deeply hollowed. The tongue, 458 which is thick, fleshy, and movable, is terminated by a cluster of sinewy papillæ, or by a cartilaginous gland. The tarsi are very short, and the feet perfected to such a degree that they really become hands, able to seize, hold, and retain small objects. Their toes are supplied with strong and hooked claws, which make these birds pre-eminently Climbers. With the exception of one single species—the Loriets (Platycercina Vigorsia, Sw.)—which have rather long tarsi and straight claws, enabling them to run with some rapidity, the Parrots, on the contrary, walk with difficulty. They drag along the ground with such trouble that they rarely descend to it, and only under pressing circumstances. Besides, they find all the necessaries of their existence on trees. They are not more favoured with regard to their flight, and we can understand that it should be so; for, living in thick woods, they only require to effect trifling changes of place, such as from one tree to another. However, some species, especially the smaller, are capable of a more prolonged and effective use of their wings. According to Levaillant, some even emigrate, and travel hundreds of miles every year; but this is an exception. In general, Parrots are sedentary, and willingly remain in localities without a desire to leave.
Sociable in their dispositions, they assemble in more or less numerous bands, and make the forests re-echo with their loud cries. To some species it is such an imperative necessity to be near each other and live in common, that they have received from naturalists the name of Inseparables. At breeding-time each couple isolate themselves for the purpose of reproduction. The male and female evince the greatest attachment to each other. The females deposit their eggs in the hollows of trees and in the crevices of rocks. The young birds are quite naked when hatched; it is not till the end of three months that they are completely covered with feathers. The parent birds wait upon them with the greatest solicitude, and become threatening when approached too closely by intruders.
Essentially frugivorous, Parrots prefer the fruits of the palm, banana, and guava trees. They may be seen perched upon one foot, using the other to bear the food to their beaks, and retain it there till eaten. After they have extracted the kernel they free 459 it from its envelope and swallow it in particles. They often visit plantations and cause great devastation. In a domestic state they are omnivorous. Besides seeds and grain, they eat bread, and even raw or cooked meat, and it is with manifest pleasure that they receive bones to pick; they are also very partial to sugar. It is well known that bitter almonds and parsley act upon them as violent poisons. They drink and bathe very frequently; in summer they evince the greatest desire to plunge into water. Captive Parrots will habituate themselves, if permitted, to the use of wine; it produces the same effect on them as on the human family, viz., excites their loquacity and gaiety. They climb in a peculiar manner, which has nothing of the abruptness displayed by other birds of the same order. They accomplish their slow and irregular movements by the help of the beak and feet, which lend a reciprocal support. Like almost all birds of tropical regions, Parrots are adorned with most beautiful colours, green predominating; then comes red, and finally blue and yellow. They have often largely-developed tails.
Notwithstanding their prattling, Parrots are the favourites of men, from their remarkable talent of imitation. They retain and repeat with great facility words which they have learned or heard by chance, and also sometimes imitate, with startling resemblance, the cries of animals, the sounds of different musical instruments, &c.
By the words that they utter in an unexpected manner, Parrots contribute to our amusement and diversion, and quite become companions. Is it, then, to be wondered at that these birds have been eagerly sought since their introduction into Europe? Alexander the Great brought into Greece a Parrot which he had found in India. These birds became so common in Rome at the time of the emperors, that they figured in their sumptuous repasts. They are now spread throughout Europe in a domestic state.
The species most remarkable for their mimic babbling faculties are the Grey Parrot, or Jaco, a native of Africa, and the Green Parrot, from the West Indies and Tropical America.
In the sixteenth century a cardinal paid a hundred crowns for a Parrot because it recited the Apostles' Creed correctly. Monsieur 460 de la Borde relates that he has seen a Parrot supply the place of chaplain to a ship, for he recited the prayer and rosary to the sailors. Levaillant heard a Parrot say the Lord's Prayer lying on its back, placing together the toes of its feet as we join our hands in the act of prayer. Willoughby mentions a Parrot which, when he said to him, "Laugh, Parrot!" immediately burst out laughing, and cried out an instant after, "O the great fool who made me laugh!" A keeper of a glass shop possessed one which, whenever he broke anything or knocked over a vase, invariably exclaimed, in tones of anger, "Awkward brute! he never does anything else."
"We have seen a Parrot," says Buffon, "which had grown old with his master, and partaken with him the infirmities of age. Accustomed to hear little more than the words, 'I am ill,' when asked, 'How are you, Parrot—how are you?' 'I am ill,' it replied in doleful tones, 'I am ill,' and stretching itself on the hearth—'I am ill.'" "A Parrot from Guinea," says the same author, "being taught on the journey by an old sailor, learnt his rough voice and his cough so perfectly that they could be mistaken. Although it had been given immediately after to a young person, and only heard his voice, it did not forget the lessons of its former master, and nothing was so agreeable as to hear it pass from a sweet and pleasant voice to its old hoarseness and the cough of early times."
Goldsmith relates that a Parrot belonging to King Henry VIII., and always confined in a chamber bordering upon the Thames, had learnt several phrases which it heard repeated by the boatmen and passengers. One day it was let fall into the Thames, when it cried with a strong voice, "A boat! a boat! twenty pounds to save me!" A waterman immediately threw himself into the river, thinking that some one was drowning, and was much surprised to find it was only a bird. Having recognised the king's Parrot, he carried it to the palace, claiming the recompense the bird had promised when in distress. The circumstance was related to Henry VIII., who laughed much, and paid it with a good grace.
The Prince Léon, son of the Emperor Basil, having been condemned to death by his father, owed his life to his Parrot, 461 which, in repeating the lamentable accents several times, "Alas! my master Léon!" ended by touching the heart of this barbarous father. M. Lemaout says:—"In a town of Normandy a butcher's wife beat her child unmercifully every day. The infant sank under the ill-treatment. The justice of man made no remonstrance, but a Grey Parrot which lived in the house of a rope-maker, opposite to that of the butcher, took upon itself the chastisement of this unnatural mother. It continually repeated the cries which the poor child uttered when he saw his mother rush at him with the rod in her hand—'What for? what for?' This phrase was uttered by the bird with such doleful and supplicating accents, that the indignant passers-by entered unexpectedly into the shop, and reproached the rope-maker with his barbarity. He justified himself by showing his Parrot, and relating the history of his neighbour's child. After some months the woman, pursued by the accusing phrase and the murmurs of public opinion, was obliged to sell her business and leave the village."
The Marquis of Langle, in his "Travels in Spain," writes thus:—"I saw at Madrid, at the English Consul's, a Parrot which has retained a quantity of things—an incredible number of stories and anecdotes—which it retails and articulates without hesitation. It spoke Spanish, murdered French, knew some verses of Racine, could say grace, repeat the fable of the Crow, and count thirty louis. They dared scarcely hang its cage at the windows; for when it was there, and the weather was fine, the Parrot talked ceaselessly. It said everything it knew, apostrophised all passers-by (except women), and talked politics. In pronouncing the word Gibraltar it burst out laughing. One would think it was a man who laughed."
An English gentleman bought a Grey Parrot in Bristol, the intelligence of which was quite extraordinary. It asked for everything it wanted, and gave orders: it sang several songs, and whistled some airs very well, beating the measure. When it made a false note it recommenced, and never committed the mistake again. We have often, when passing through the Rue Four-des-Flammes, at Montpellier, heard a Parrot which sung and articulated most distinctly the two verses of this song:— 462
Parrots imitate not only the words, but even the gestures of those with whom they come in contact. Scaliger knew one which repeated the songs of some young Savoyards, and imitated their dances.
These birds are more or less susceptible of education. Some, naturally peaceable, are easily tamed; others, more refractory, submit to captivity unwillingly. In general, when they are taken young they attach themselves strongly to those who have care of them.
Parrots have a mania for using their beaks upon everything that comes in their way. When encaged against their will they utter loud cries, and sometimes turn their fury upon the bars of 463 their prison. They have been known to pluck and even tear themselves in these paroxysms. Supplying them with a plaything is the only means of keeping them quiet under such circumstances.
These Climbers are endowed with remarkable longevity. The "Memorandums of the Academy of Sciences of Paris" mention a Parrot that lived in the family of the Grand Duke of Tuscany, in Florence, more than a hundred and ten years. Vieillot speaks of having seen one near Bordeaux which was eighty-four years of age. The average length of their life cannot, however, be exactly ascertained.
Parrots rarely breed in Europe; it is true they often lay, but the eggs are sterile. A few instances have been known in France where, under favourable circumstances, they have perpetuated their species. Generally all that we see in our temperate regions are brought from countries where the majority have been taken from the nest. Different means are employed to capture the adults, all of which have for their aim to stun them for an instant, in order to paralyse their movements. 464
The family of Parrots comprises four principal groups—the Macaws, Parrakeets, Parrots properly speaking, and Cockatoos.
The Macaws (Fig. 184), the largest of the Parrots, are recognisable from their bare cheeks and long tapering tails. They inhabit South America, and are arrayed in the most brilliant colours. The principal species are the Red, the Blue, the Green, and the Black Macaws. The name Arara, by which they are known in their habitat (Brazil), describes the deafening cries which they utter. Very fami
