Chapter L: THE RAZORBILL OR AUK (Alca torda) 100 (4)

In the pairing-season, which takes place during December and January, the old rams, like the males of most ruminants, engage in fierce combats for the possession of the females. The ewes give birth to their one or two lambs during April and May; and these, like the lambs of domesticated sheep, are able to run with their mothers at a very early age. When the rams are in good condition, mouflon-mutton, if hung long enough, is excellent for the table.

In Cyprus, Asia Minor, and Persia the mouflon is replaced by the red sheep (_Ovis orientalis_), a redder and, in the case of some races, larger species, often with a fringe of blackish hair on the throat of the old males, and the horns in that sex always curving backwards behind the neck. The race of this species inhabiting the Troödos mountains of Cyprus is smaller than the rest.

Farther east, namely, in the Kopet Dagh range dividing Persia from Turkestan, the red sheep gives place to the well-known urial (_O. vignei_), in which there is a long white throat-fringe to the old rams, whose horns curve forwards by the sides of the face. This species ranges through Baluchistan and Afghanistan to the Salt Range of the Punjab, and thence along the ranges flanking the Indus into Ladak and Tibet.

In the Altai and Tibet, together with other parts of central Asia, we reach the country of the great argali sheep (_O. ammon_), with its numerous races; while in the Yana Valley of Siberia and in Kamchatka we first meet with the so-called bighorns (_O. canadensis_), of which the typical race is North American. One peculiar species (_Ammotragus lervia_) inhabits the north of Africa, but in the rest of that continent, as also in peninsular India, the Malay countries, and South America, wild sheep are unknown.

THE RED DEER

(_Cervus elaphus_)

The red deer, the typical representative of the family _Cervidæ_, is the largest and handsomest European member of that group, although it attains its maximum development in point of bodily size and massiveness of antlers only in eastern Europe and south-western Asia. As in most members of the deer tribe inhabiting temperate countries, there is considerable seasonal difference in the colour of the coat, and the fawns differ remarkably in this respect from their parents. There are also distinctions in colour between the various local races of the species. The ordinary name refers to the fact that in summer a more or less distinct rufous colour prevails on the upper-parts. Here it may be remarked that deer do not in most cases present that marked contrast between the upper and the lower surfaces of the body so characteristic of gazelles and many other members of the antelope group. And the reason for this is not difficult to explain. As mentioned in the text accompanying the plate of that species, the white under-parts of the gazelle are for the purpose of counteracting the dark shadow thrown by the body when standing in full sunlight, and thus to render the animal inconspicuous. Deer, on the other hand, are in the main nocturnal and forest-dwelling creatures, and this type of protective colouring would therefore be useless in their case. The chital, or Indian spotted deer, is, however, much less nocturnal than most species, and also feeds to a great extent in the open; and it is interesting to notice that, in accordance with such habits, this species is white-bellied.

Notable features in the red deer are the shortness of the tail, and the straw-coloured patch on the buttocks in which that brief appendage is included; the same features recurring in its near relative the wapiti. As in all similar cases among ruminants, the light rump-patch serves as a guide to the members of a herd; the place of this being taken in certain other species, such as the fallow deer and the American white-tailed deer, by the pure white under surface of the tail, which is raised when the animals are running.

The antlers of the stag are characterised by the number and regular arrangement of the tines; and more especially, in their fullest development, by the duplication of the first, or brow, tine, and the cup-like arrangement of the terminal snags.

Two features indicate that the red deer is what naturalists term a highly specialised animal. These are, firstly, the shortness of the tail, and, secondly, the white-spotted coat of the fawn, so utterly different from that of the adults of the typical western representative of the species. In the race inhabiting the Caucasus yellowish spots are, however, frequently observable in the coats of full-grown hinds, while similar spots may be developed in adult stags of the North African race,--the so-called Barbary deer. These features clearly indicate that the red deer is descended from a species which was fully spotted at all ages.

The range of the red deer includes, with the exception of the far north, practically the whole of Europe, as well as Asia Minor and part of Persia. From many parts of western Europe these splendid animals have, however, been exterminated; and in the British Isles they survive in a wild state only in Devon and Somerset, the highlands and isles of Scotland, and parts of Ireland. The red deer of the Caspian district and the neighbouring countries, commonly known (from its Persian name) as the maral, is a much larger and also a greyer animal, with heavier antlers, than its west European representative. The latter have been split up into several local races, which need not, however, be particularised in this place.

The food of the red deer varies considerably according to the time of year, and comprises grass and other herbage, corn, leaves and boughs, bark, acorns, chestnuts, funguses, lichens, and moss. In autumn, when living near cultivated ground, deer will dig up with their hoofs, potatoes, artichokes, and other edible roots.

The pairing-time commences early in September, and continues till the middle of October; and at this season, when they utter the well-known bellowing or roaring, the stags not only fight fiercely among themselves for the mastery of the herd, but are highly dangerous to human beings. At no time very amiable, the stags at this season are little better than incarnate fiends. Soon after the breeding-season the antlers are shed, to be replaced by new growths, covered at first with soft velvety skin, the following spring.

At the end of May or early in June the hind seeks a sequestered situation amid covert in which to give birth to her fawn. The fawns, of which there may occasionally be twins, are extremely helpless at birth, but in a short time gain sufficient strength to run by the side of their mothers.

THE BEAVER

(_Castor fiber_)

The beaver enjoys the distinction of being the only warm-blooded quadruped that is in the habit of making really noticeable modifications in the appearance of the earth’s surface. Many quadrupeds, such as foxes, ant-bears, rabbits, and rats and mice burrow holes in the ground, while the mole marks the course of its subterranean tunnels by throwing up heaps of earth at intervals. But although such excavations and hillocks, when sufficiently numerous, may to a slight degree affect the appearance of a meadow, they are nothing in comparison to the changes brought in a valley by a colony of beavers. By throwing a dam across its course, these industrious rodents will convert a narrow stream into a wide sheet of stagnant water, which in the course of time may become silted up so as to form a broad and level “beaver-meadow,” where there was originally a rocky valley. In or near their dams beavers likewise construct dwellings of mud and clay, known in America as “lodges,” for their own accommodation.

But this is by no means all beavers accomplish in the way of “public works,” for, by means of the single pair of powerful chisel-like teeth in the fore part of each jaw and the powerful muscles by which the jaws themselves are worked, these animals, which are about the size of an ordinary spaniel, are enabled to fell trees of considerable size, which are used in the construction of their dams.

Beavers are the sole living representatives of a family of rodents allied on the one hand to squirrels and dormice, and on the other to rats and mice. Two structural peculiarities are very characteristic of these rodents. In the first place, one of the toes of the fore-foot is provided with a double claw, which may be used in dressing the beautiful, long brown fur; a similar structure occurring in the smaller rodent known as the Arctic lemming (_Dicrostonyx torquatus_). Secondly, there is the remarkable flattened, scaly tail, which almost looks as though it did not belong to the animal, although in reality, except for its superior size, it is not much more abnormal than the scaly cylindrical tail of the rat. Several myths attach to the beaver’s tail; it was said, for instance, to be employed as a trowel for plastering down the mud used in building the dams and lodges, although its real use is to act as a rudder in swimming, more especially when its owner is transporting the trunk of a felled tree. When entering the water, or when engaged in playing therein, the beaver frequently makes a resounding “smack” by striking the surface with its tail.

In monkish times beaver-tail was considered to partake more of the nature of fish than flesh, and was consequently allowed to be eaten on fast days. This was, however, in the days when beavers were still abundant in all the great rivers of Europe, from most of which they have now been all but exterminated for the sake of their valuable fur, and likewise for the odoriferous secretion known as castoreum, which was formerly much used both in medicine and in perfumery. When the last beaver was killed in the British Isles is unknown, but the species still survived in Wales when the old chronicles were written; and we have testimony as to its former existence in England not only in the shape of skulls, teeth, and bones dug up from time to time in the peat of the fens and other superficial deposits, but also in place-names such as Beverley, in Yorkshire.

Considerable colonies of beavers still exist, by the aid of special protection, in certain parts of Scandinavia, while a few are taken from time to time in the Rhone, but from the Rhine, and even the Vistula, they seem to have completely disappeared. In eastern Russia they probably still survive locally, as they doubtless do over a large part of Siberia, although our information on this point is very defective. Indeed the southern range of the beaver in central Asia seems to be still unknown, although it is certain that the species never existed in Kashmir or the Himalaya.

Of late years it has been suggested that each of the great European river-systems possessed a special race of beavers of its own; but the evidence adduced in favour of this opinion is at present insufficient. Speaking broadly, the beaver may be regarded as a circumpolar animal; although its American representative has been separated, on account of a comparatively small difference in the shape of the bones covering the cavity of the nose, as a distinct species, under the name of _Castor canadensis_. Unfortunately, the Canadian beaver has been almost as much persecuted as its European relative, and has been exterminated from many districts.

Beavers, it need scarcely be mentioned, are thoroughly aquatic rodents, which feed on vegetable substances, and have their entrances to their habitations under water. They remain active all the winter, when they swim beneath the ice. In Europe beavers have given up constructing lodges, and live in burrows.

THE MARMOT

(_Arctomys marmotta_)

The marmot of the Alps is the typical representative of a large assemblage of burrowing rodents near akin to squirrels; the head-quarters of the group being in central Asia. By rights, of course, the name belongs exclusively to the typical species, but as it has been extended to include all the members of the group, the former is now distinguished as the Alpine marmot. Marmotte, it appears, is the Savoyard name of this rodent, which in the Engadine is designated marmotella, while its German designation is murmeltier.

The typical marmot is confined to Europe, and mainly to the high ranges of the Alps, Pyrenees, and Carpathians. In eastern Europe and western Asia it is replaced by the bobac (_Arctomys bobac_); and in central Asia there are a number of species, of which several are considerably larger and more brightly coloured than the Alpine animal; none is found to the south of the main range of the Himalaya, and the group is represented elsewhere only by the so-called woodchuck (_A. monax_) of North America, which attains a length of about 24 inches.

The general colour and appearance of the Alpine marmot are well shown in the Plate; and it will suffice to direct attention to the shortness of the ears as a feature connected with burrowing habits. In one Himalayan species the tail is considerably longer. In the Alps marmots dwell high up among bare rocks, above the zone of vegetation, where not even goats venture, and where it frequently snows for six weeks together in winter. In such desolate situations these hardy rodents make their home in the little islands of rocks between the glaciers. Himalayan marmots, on the other hand, live at an elevation where a considerable amount of vegetable growth flourishes in summer; their burrows being frequently excavated beneath clumps of wild rhubarb.

As summer resorts, Alpine marmots select situations with a southerly, easterly, or westerly aspect on the mountain slopes, and here they construct their summer dwellings, which are designed to afford them shelter in bad weather and to serve as a refuge from danger. In autumn they dig deeper into the sides of the mountains to construct their winter burrows and chambers, which have to afford accommodation for the entire family, whose number generally ranges between five and fifteen individuals. The burrow terminates in a large chamber, which is filled with soft, short hay. As early as August these rodents begin to collect grass, which is spread out on the hillsides to dry, and then carried into the burrows.

The entrance to the burrow is only just wide enough to admit the owners, and at the commencement of the winter-sleep is blocked with earth, stones, clay, grass, and hay. When this work is completed, the whole family falls into a death-like sleep lasting from six to eight months; in this torpid condition, well protected from the intense cold, they remain till awakened to new life by the warmth of returning spring.

Marmots feed upon a number of different kinds of Alpine plants, as well as on the fresh or dried grass found in the neighbourhood of their burrows. When eating, they sit up on their hind-legs and hold the food in their mouths after the manner of squirrels; and the herbage they consume is so full of sap, that they seldom require to drink. The same upright position is assumed when they first come out of their burrows, in order that they may see whether all is safe; if danger threatens, they utter a shrill whistle and disappear with marvellous rapidity into the depths of the burrow. Frequently they take up their position on some large rock in the neighbourhood of the burrow, on which they can either sit up and survey the prospect, or bask in the warmth of the summer sun.

Their extraordinary wariness and the rapidity with which they disappear from view are due to their numerous enemies, among which man, foxes, and eagles and other birds-of-prey are the chief. It requires only the shadow of an eagle’s wings to make them utter their piercing, whistling scream and vanish into the holes, from which they do not reappear for some time. As a rule, they only remain above ground while the sun is shining, and they keep entirely below during bad weather, so that they are regarded by the peasants as weather-prophets.

To the Savoyards and other Alpine peasantry the marmot is a valuable animal; its flesh being much esteemed as food, when it has been freed from a certain disagreeable odour by smoking. The fat is regarded as a remedy for many diseases; and a freshly removed marmot skin is considered wonderfully efficacious in cases of rheumatism. Marmots are caught either by trapping or by digging them out of their burrows. Years ago Savoyard organmen used frequently to be accompanied by a marmot or two.

THE HAMSTER

(_Cricetus frumentarius_)

The hamster, which, although abundant in many parts of the Continent is unknown in the British Isles, is the typical representative of a large section of the mouse tribe characterised by the cusps on the upper cheek-teeth forming two longitudinal rows, instead of the three found in those of ordinary rats and mice. In size it may be compared to a rat, but its tail is reduced to a mere stump, not more than a couple of inches in length; while it is further characterised by the brilliant and variegated colouring of its fur. Short-legged and stoutly built, it has relatively small, membranous ears, large brilliant eyes, a rather sharp muzzle, small toes, and short claws. The glossy, hairy fur is underlain by a thick woolly under-fur. Very characteristic of this animal is a narrow line of fur darker than the rest on the middle line of the back which marks the position of a gland.

In general colour the fur of the upper-parts is light brownish yellow; but the sides of the face are variegated with chestnut and white, and there is a white area on the shoulder, while the under-parts and the greater portion of the limbs are black, the black extending upwards to some extent behind the fore-legs. Hamsters are, however, subject to considerable individual variation in colour, and black, pied, and even white examples are by no means uncommon.

Soft dry soils other than loose sand, which is unsuited for its burrows, form the favourite resorts of the hamster, which in localities of this nature ranges from the valley of the Rhine to that of the Obi in Siberia. Its distribution is, however, very local, and the species is unknown in the southern and south-western districts of Germany, as it is also in eastern and western Prussia: in Thuringia and Saxony, on the other hand, it is abundant.

The chief interest of the hamster is concentrated in its remarkable habits. These rodents associate in large societies; and, like marmots, construct both summer and winter burrows, in the latter of which they become torpid during the cold months of the year. The winter-burrow includes a large sleeping-chamber, situated at a depth of from one to two yards below the surface; and also a storehouse or granary, in which quantities of corn of various kinds are collected by these industrious rodents for use during such portions of their retirement as they are active. The burrow leading to the dwelling-chamber descends almost perpendicularly, but takes a turn before opening into the chamber itself, which is likewise provided with an oblique emergency exit. Although grain forms their chief nutriment during the period of retirement, hamsters in summer consume large quantities of peas, beans, roots, fruits, and grass and other green food.

As a rule, hamsters retire from the world to their subterranean dwelling-places some time during October; when they block up the entrances and exits of the winter-burrows with earth. Apparently they almost immediately enter on their winter-sleep, from which they do not awake till the following February or March, according to the temperature. The weather at this early period of the year is, however, by no means suited for an out-door existence, and these rodents accordingly subsist for a season on their hoarded grain. The old males generally make their appearance above ground about the middle of March, but the females defer their emergence till a fortnight or so later. They are then ravenously hungry, and will devour almost anything that comes in their way, including beetles or other insects and an occasional bird or mouse.

In summer the nest-chamber of the females, which is distinct from the summer-burrow of the males and is furnished with one exit and several entrances, is carefully lined with hay. Towards the end of April the males visit the females in their own apartments; and four or five weeks later the first litter of blind and naked young--varying in number from half a dozen to eighteen--is produced. These rapidly develop their fur, and open their eyes about the eighth or ninth day; and within a fortnight are driven away from the parental burrow to construct a new one of their own. Freed from one family, the old hamsters set about producing a second one, which usually comes into the world in July. The annual increase is, however, by no means limited to the older individuals, for the members of the early spring litter are able to produce young ones in the autumn.

Hamsters frequently make their appearance in enormous swarms, when they do vast damage to crops. In return, the winter granaries of these rodents are frequently raided by the peasants of countries where they are common; the flesh of the hamster is also eaten, and its fur employed for lining cloaks and coats.

THE DUCKBILL OR PLATYPUS

(_Ornithorhynchus anatinus_)

For many years it was reported by the natives of Australia that the extraordinary warm-blooded quadruped known to naturalists as the duckbill, or platypus, produced its young from eggs laid in a burrow by the female. That a mammal--and a mammal, although of an altogether peculiar and out of the way type, the creature undoubtedly is--should lay eggs was, however, too much for the minds of stay-at-home naturalists, and the fiat accordingly went forth that the native story was to be discredited. And discredited it therefore was. In nature, as in other things, truth will, however, ultimately prevail; and we now know for certain that the female lays in a burrow in the bank of some river or pool a couple of hard-shelled, oval eggs, which in due course hatch out into naked, helpless young, furnished with soft sucking lips. Not that they suck in the ordinary mammalian fashion, for the female platypus has no nipples, but her milk oozes out in the breast from a number of sieve-like pores, from the surface of which it is sucked up by her offspring.

Such a difference from the ordinary mammalian way of doing business proclaims the wide distinction between the platypus, and, it may be added, its relatives the spiny ant-eaters or echidnas (one of which forms the subject of another illustration), and all other warm-blooded quadrupeds. Nor is this all, for in the structure of their skeleton and soft internal parts the platypus and the echidna display many marks of affinity with reptiles and birds, which are totally wanting in other mammals. These two creatures represent indeed a group by themselves, so that mammals may be divided into two great primary sections, the one embracing only the two egg-laying types, and the other all the rest.

And it is not a little significant that the egg-layers are confined to Australia and New Guinea, the home of many other primitive and ancient types which have disappeared from the rest of the world. In one sense indeed the platypus and the echidna are not exactly primitive creatures, as they have several specialised characters which were evidently wanting in their ancestors. They may rather be described as specialised branches of an ancient and primitive stock.

The duckbill is a heavily made aquatic mammal of about the size of a very short-legged rabbit, with blackish, mole-like fur above, passing gradually into whitish beneath, and a short, thick, tapering tail. The very short limbs terminate in thick toes, connected together by a web and armed with strong, pointed claws. In the fore-feet the margin of the web projects considerably beyond the claws, but on the rare occasions that the animal leaves the water the margin is folded downward beneath the claws, so as to leave the claws exposed. In museum-specimens, however, the web is almost invariably shown fully expanded, as in the accompanying illustration; a condition in which it would obviously be impossible for the animal to walk on land.

The most remarkable external feature of the duckbill is undoubtedly the duck-like, naked beak, pierced with two holes representing the nostrils. In stuffed specimens, at any rate, this beak is dark-coloured and horny in consistence, and looks as though it did not belong to the animal, but in life it is soft and tender. Medium-sized, dark eyes complete the physiognomy of this strange creature, in which external ears are wanting.

The internal arrangements of the mouth of the duckbill are scarcely less curious than the exterior. In early life the mouth is furnished, both above and below, with three pairs of somewhat quadrangular cheek-teeth, with raised and cusped margins. Beneath these grow up certain large horny plates, and about the time that full maturity is attained the teeth become worn out, and are finally shed, thus leaving the horny plates as the sole masticating organs.

This replacement of the teeth by horny plates appears to be connected with the nature of the food, for while in early life the duckbill appears to subsist mainly on water insects and other comparatively soft aquatic creatures, later on it takes to feeding almost entirely on bivalve shells of one particular species; and for crushing the stout shells of these molluscs it has been suggested that the tough horny plates are better suited than brittle teeth.

Duckbills, except when in their burrows, pass the greater portion of their time in the water, selecting quiet pools for their favourite haunts. In such situations they may be seen on a still evening floating and diving, and looking more like bottles in the water than anything else. They obtain their food chiefly by probing in the mud with their duck-like beaks. The dwelling-chamber of the burrow is situated in the bank above the water level, but its entrance is below the surface, although there is also an exit on the land. In the pairing-season the males, which are armed with a poison-bearing spine on the inside of each hind-leg, fight fiercely among themselves.

The duckbill, of which there is but a single species, is absolutely confined to southern and eastern Australia and Tasmania; and its nearest living relative is the echidna, of which a picture and notice follow.

THE SPINY ANT-EATER OR ECHIDNA

(_Tachyglossus aculeatus_)

No one who looked at the portrait of the spiny ant-eater for the first time, and had no knowledge of its anatomy or history, would be likely to guess that it was a near relative of the duckbill. But in natural history, when we have to deal with members of different groups, externals count for very little, and all depends upon internal organisation. In the latter respect the echidnas, for there is more than one species, resemble in all essential features the duckbill, as they do in laying hard-shelled eggs, from which the young are eventually hatched. The single egg of the echidna, in place of being laid in a burrow, is, however, carried about by the female in a pouch developed for the purpose on the under side of her body shortly before the egg is laid; and in this same temporary pouch the young is likewise nurtured during the earlier stages of its existence.

The duckbill and the echidna afford an excellent example of the diversity of appearance produced in animals more or less nearly related to each other by specialisation and adaptation to totally distinct modes of life. In the duckbill the specialisation and adaptation are for an aquatic existence; in the echidna they are for a burrowing, terrestrial life and a diet of ants.

To an ant-eater teeth of any kind would be not only useless, but an actual hindrance, and they have accordingly been discarded, while the muzzle has been prolonged into a decidedly bird-like beak. In this respect the echidna much resembles the great South American ant-eater, which belongs to a totally different group of mammals.

To enable it to dig out the nests of the ants which form its chief food, and likewise to excavate the burrows in which it passes the day, the echidna is armed with powerful claws, those on the hind-feet being, however, much larger and more curved than those in front. It is with these strong hind-claws that the earth loosened by the fore-feet is thrown out from ants’ nests and the burrow. Like the porcupine, which is also a nocturnal and a burrowing creature, the echidna has its back protected with an array of parti-coloured horny spines mingled with hairs. The degree of development of the spines is, however, subject to great variation; and there is one race in which the hair predominates, and the spines appear only in the midst of the dense brown fur. Like the platypus, the echidna has no external ears.

The ordinary, or five-toed, echidna has a much more extensive range than the platypus, occurring, in suitable localities, not only all over Australia and Tasmania, but likewise in New Guinea. The last-named island is likewise the home of the much larger three-toed echidna (_Proechidna bruijnii_), in which the beak is longer, more slender, and distinctly curved, while the number of the toes on each foot is reduced to three.

With the commencement of evening the echidna issues forth from the lair or burrow, in which it has passed the day, in search of food--this comprising not only ants, both ordinary and white, but likewise such other insects and their grubs as may be encountered or dug up during the nocturnal wanderings. Soon after daybreak the creature returns to its burrow. During the hottest and driest part of the Australian summer spiny ant-eaters fall into a torpid condition, when they exist for weeks at a time on no other nourishment but their own fat. In cases of extreme hunger they are stated to fill their stomachs with sand. At the end of the dry season, when rain falls and the country resumes its verdure, the echidnas wake up, and the males relinquish their normally solitary life and take to themselves partners.

On occasions of danger the echidna has two means of defence--it can either roll itself up into a ball and present a sphere of spikes to its enemy, or it can burrow with such rapidity that it actually seems to sink into the earth as if swimming.

The single egg appears to be conveyed to the pouch by the female in her mouth, and the parent assists the young echidna, whose muzzle is armed with a special knob for that purpose, in breaking the shell. Naked and blind when first hatched, the young one remains in the pouch till its spines make their appearance, drawing its nutriment from two pores through which the milk flows. When the young echidna has been turned adrift in the world to shift for itself, the maternal breeding-pouch shrivels up, to be re-developed the following year.

As in the case of the platypus, no remains of extinct echidnas are found anywhere except in the superficial deposits of Australia itself. Certain teeth from rocks older than the Chalk, both in Europe and America, may, however, indicate the ancestral stock of the egg-laying group.

THE BLACK SWAN

(_Cygnus atratus_)

When the old Roman poet penned the well-known line, “Rara avis in terris, nigroque simillima cygno,”[A] he little imagined that a black swan was actually living in the then unknown and undreamt-of Antipodes, to be discovered in the dim and distant future by the sailors of a little island in the far north inhabited by fair-haired barbarians of whom he may or may not have heard.

[A] “A rare bird in the world, and most like a black swan.”

The black swan of Australia, from which the Swan River takes its name, is not perhaps the ideal black swan of the poet, for, as a matter of fact, it has a good deal of white in its wings, although but little of this is visible when the wings are closed, as in the illustration. Moreover, the general colour of the plumage is brownish black, rather than pure black, while the beak is crimson with a white tip, and the eyes are scarlet. From all other swans this species differs by the curling feathers in the region of the shoulder, and the extreme shortness of the tail. Other distinctive features are to be found in the compressed body, the long neck, the small, gracefully carried head, and the absence of a ridge to the beak.

The range of the black swan includes both Australia and Tasmania, where it is found not only on the coast, but likewise on the rivers and lakes of the interior. In the earlier days of Australian colonisation it abounded in many parts of the country; but, unfortunately, it is a bird by no means shy, and therefore comparatively easy to shoot, and in consequence of this it has been incessantly and relentlessly persecuted, even the cygnets, while still unable to fly, being hunted among the reeds in the swamps and killed out of pure maliciousness. As a result of this persecution the species has everywhere become scarce, and from some parts of the country has been exterminated.

During the winter months these swans collect in small parties and families in South Australia, and return to their breeding-places in spring. The nest is a huge, ill-built structure, made out of coarse materials and lined with sedge. It is generally situated in the neighbourhood of small islands, where the parent birds can readily collect the large amount of material required for its construction. The clutch consists of from five to seven dirty white or pale green spotted eggs, which are brooded with great assiduity by the female, while the male keeps guard in the neighbourhood. The cygnets are clothed in a grey or rufous down, and can swim and dive as soon as they are hatched. The food of both young and adults comprises water-plants of all kinds, as well as worms, molluscs, and small frogs and fishes.

The black swan is a noisy species, more especially during the pairing-season, when it gives vent to loud trumpetings. When doing so, the neck is stretched out straight along the water, so that the beak lies close to the surface. At this season the males become very pugnacious, and fight much among themselves.

It is a beautiful sight to watch a party of these swans swimming on a still lake or river by moonlight in large circles; but this is exceeded when the birds mount into the air and reveal the striking contrast formed by the white of the pinions against the sable of the rest of the plumage. When flying, these swans stretch out their necks to the fullest extent, and accompany the loud and regular beat of their wings with continuous and resounding trumpetings.

The black swan bears captivity well, alike in its own country and in Europe, being content with small rations and breeding regularly every season.

The Australian black swan is by no means the only abnormally coloured member of its tribe inhabiting the Southern Hemisphere, its place in South America being taken by the black-necked swan (_C. nigricollis_), which is a native of Chile, Argentina, and some of the other southern countries. In this handsome species the head and neck are black, and the remainder of the plumage white; the lores, or bare patches in front of the eyes, and the basal portion of the beak being red. In its long and wedge-shaped tail the black-necked swan differs from the black species and resembles the ordinary European mute swan (_C. olor_), from which it is structurally distinguished by the scalloped margins of the webs of the toes. The adults of all swans, except the black and the black-necked species, are wholly white; the smallest kind is the coscoroba swan of South America, which is no larger than a goose, and has been referred to a genus by itself.

THE BUSTARD

(_Otis tarda_)

By the extermination of the bustard, or great bustard, as it is sometimes called in order to distinguish it from its smaller relatives, the British Islands have lost one of the finest members of their bird fauna; and, unfortunately, all attempts to rehabilitate this magnificent species have resulted in failure. It is to be feared, moreover, that any such attempts have but little chance of success in the future, for the bustard is a native of open downs and fallows, where it must live an undisturbed and untrammelled existence, and in England at the present day this is almost an impossibility in country of that description. In this respect the bustard stands at a great disadvantage in comparison with the capercaillie, whose reintroduction into the forests of Scotland was a relatively easy matter.

Like those of most polygamous birds, the cocks of the bustard are much larger than the hens, rivalling full-grown turkeys in the matter of size; they are also much more attractively coloured, and are furnished with a quantity of white fluffy plumes, which are only fully displayed when the birds perform their curious nuptial parade to attract the hens, although some of them may be seen when two cocks are fighting, as depicted in the plate. Another peculiarity of the cock is the possession of a great pouch, communicating with the windpipe, on the throat, which can be inflated under the influence of excitement.

When the wings are closed and the bird is engaged in feeding or other normal occupation, the colouring of the body-feathers of the cock bustard is admirably adapted to harmonise with the generally sandy or earthy hue of the surroundings. In the case of the hen the whole plumage is protectively covered. The one feature of the body-plumage in both sexes which produces such a wonderful harmony between the colouring and that of the surroundings is the presence of a vast number of narrow black bars on a rufous buff ground, this type of colouring not only matching sandy or loamy soil, but likewise aiding to break up the outline of the bird.

When bustards lived in England their favourite resorts were the dry, heathy uplands of Norfolk and Suffolk, and the downland of Cambridgeshire, and the neighbourhood of Royston. At the present day these splendid birds are still common in many parts of the Continent, their range including the greater portion of central and southern Europe and a large extent of central Asia, while in winter it likewise embraces northern Africa. The steppes of Russia, the plains of the Danube in its course through Hungary, and the open tracts of central Asia are the regions where bustards are now to be met with in the greatest numbers, although large flocks may be seen in parts of Spain.

Bustards, which associate in large flocks, are essentially birds of the open country, never entering woods, and preferring elevated ground, whence they can command a wide view of the plains below, to which they descend during the daytime in search of food. They are exceedingly shy and mistrustful, giving every bush in their path a wide berth, lest it should conceal a lurking foe, and taking to flight on the least alarm. For warning of the presence of danger they seem to depend mainly upon sight, although their hearing is also good; on the other hand, their sense of smell, like that of most birds is but poorly developed. This excessive shyness renders the bustard a difficult bird to bag, even by the experienced gunner.

At the commencement of the pairing-season the cocks endeavour to attract the attention of the hens by their nuptial display. Advancing towards the latter they ruffle out their feathers like an excited turkey-cock, at the same time lowering their wings and spreading out the tail like a fan. The gular pouch is also inflated, so as to make the neck appear as thick as possible, and the beautiful under feathers are displayed to the utmost extent, the body and neck being half buried in a billowy mass of snow-white plumes. It is at this time also that the cocks rush at one another with trailing wings to contend with beak and talons for the mastery. On such occasions it is possible to capture these generally shy birds with the hand.

The nest is generally constructed amid growing corn, the hen merely scratching a slight hollow in the ground, which she lines with straw, bents, and grass. The three or four eggs are incubated by the hen alone, and when the young are hatched, both these and their parents leave the standing corn only for short periods. At first the young bustards feed chiefly upon insects and worms, to which they are directed by the old birds, but later on vegetable substances constitute almost their sole food. Young peas and cabbage form very favourite food, but in default of better nutriment grass is largely eaten.

THE SOMALI OSTRICH

(_Struthio molybdophanes_)

Ostriches, which are natives of the deserts and semi-desert plains of Africa and south-western Asia, cannot possibly be mistaken for any other birds, and therefore stand in no need of description, although it may be as well to mention that they are the largest of living birds, and are absolutely peculiar in having only two toes to each foot, as well as in the absence of feathers on the thigh. It was at one time considered that the lack of the power of flight, which characterises these birds in common with their relatives the rheas of South America, the emu of Australia, the cassowaries of Austro-Malaya and Australasia, and the tiny kiwis and rheas of New Zealand, was a primitive feature. But this is manifestly an erroneous idea, and all these groups are evidently descended from birds endowed with the power of flight, their nearest relatives being the tinamus of South America and the game-birds, with which they agree in the presence of longitudinal light stripes on the downy dress of the chicks.

Naturalists now recognise four kinds of African ostriches, which, although generally classed as distinct species, might perhaps be better regarded as local races of a single specific type. These, regarded as species, comprise the typical red-legged and red-thighed North African ostrich (_Struthio camelus_), ranging into Palestine and Arabia, and laying thickly pitted eggs; the Somali ostrich (_S. molybdophanes_), characterised by its bluish grey neck and thighs; the Masai ostrich (_S. masaicus_) of East Africa, with the bare parts red, the body-plumage of the cocks brownish black in place of black, and the eggs pitted; and, lastly, the South African _S. australis_, which lays smooth-shelled eggs and has the neck and thighs light bluish grey. In the Somali ostrich, which inhabits Somaliland and western Gallaland as far as the Juba River, the colour of the bare parts of the body may best be described as grey or slaty blue, while the margins of the beak and the front surfaces of the lower part of the legs are dull vermilion.

Ostriches are essentially gregarious birds, associating either in small family parties comprising five or six birds, or in large flocks, which in East Africa mingle freely with herds of hartebeests, gnus, and bontequaggas. They require a wide extent of open country, with grass and, above all, water, of which they drink frequently and copiously. Although ostriches feed chiefly upon vegetable substances, they likewise consume worms, insects, molluscs, reptiles, and probably also small birds and mammals, while in captivity they will swallow almost anything that is offered them, including nails, keys, and copper coins. In a state of nature they swallow sand, earth, and small stones, in order to assist the action of their gizzards.

The cocks appear to be polygamous, although some doubt has been expressed as to whether this is really the case; and it seems certain that several hens lay in the same nest, where as many as thirty eggs may be laid in a slight hollow in the sand. Incubation is undertaken by the cock alone, and it is he who looks after the chicks, which he tends with remarkable care. The chicks when they escape from the eggs (each of which weighs as much as twenty-four hens’ eggs) are as large as hens; and, with their bristly feather-quills, are rather suggestive of two-legged hedgehogs.

Ostriches are extremely shy and remarkably swift birds, so that they are difficult either to stalk or to ride down. When brought to bay, or when running loose in captivity, they should be approached with great caution, as a kick from their strongly clawed feet will prove fatal to an animal of the size of a jackal, if not also to a human being. The vision of these giant birds is very strongly developed and capable of sweeping the country to the distance of at least a mile; and their senses of hearing and smell are also good, although taste appears to be practically wanting. Occasionally ostriches indulge in a kind of dance; and they are also subject, when startled, to sudden collapse, which may have given rise to the old fable of their burying their heads in the sand and leaving their bodies exposed.

If allowed sufficient space, ostriches thrive remarkably well in confinement; and ostrich-farming, for the sake of the lovely white plumes of the cocks, has become an important industry, not only in Africa, but in many other parts of the world. Ostrich-farming was commenced in Algeria, and by 1865 had been introduced in Cape Colony, whence it has spread northwards, while it has also been established in Egypt, southern Russia, California, Patagonia, and Argentina. The cocks are clipped regularly every eight months.

THE PIED HORNBILL

(_Buceros bicornis_)

The hornbills, which are as large as big eagles, are some of the most extraordinary and bizarre of all birds, not only on account of the huge beaks from which they take their name, but from their strange and unique nesting-habits. In the enormous development of the beak these Old World birds are paralleled by the toucans of tropical America, although the two groups are in nowise nearly related. Such a huge and apparently unnecessary structure might at first sight seem too heavy and bulky for the bird by which it is carried; but internally the beak is generally a mere delicate tissue of bone, so that its weight is really very slight. Indeed, these enormous beaks are in most cases probably much less of an incumbrance to their owners than are the matinee hats favoured by ladies of the present day.

The pied, or double-horned species, the hornray of the natives, inhabits the dense forests of the Indo-Malay countries from the Himalaya and the Indian peninsula to the south of China and Sumatra. The glossy plumage is mostly black above, with the under-parts, the neck, the tips of the flight feathers, and the tail feathers more or less white or whitish, the upper half of the huge beak, with its horn-like appendage, being reddish yellow, and the lower half yellow. The total length of the bird, which is the largest member of the whole group, exceeds a yard. The so-called “horn,” or casque, forms a more or less flat and oblong platform on the upper part of the beak and the fore part of the head, terminating in front in two obtuse corners. On the other hand, the same appendage in the nearly allied rhinoceros-hornbill, or engan (_Buceros rhinoceros_), is much more horn-like, as it turns up into a recurved point in front.

The range of the hornbill group includes Africa, India, Malaya, Celebes, and New Guinea and the neighbouring islands as far as the Solomon group. The ground-hornbills are solely African, while the hollow-casqued section has a distribution equivalent to that of the group. One very remarkable Malay species, the solid-billed hornbill, the teban-mertua of the Malays (_Rhinoplax vigil_), differs from all the rest in having the beak and casque solid. This species is much hunted by the Chinese for the sake of its beak and casque, which have a structure resembling ivory, and are used as a substitute for that material in carving; while it is further remarkable for its bare neck and the elongation of the middle pair of tail feathers.

The flight of hornbills is heavy and noisy, the swishing sound produced by the wings being audible at a great distance. The whole body of these birds is permeated by air-tubes connected with the wind-pipe, and it is said that the movement of the air in these increases the noisiness of the flight.

Mountain-forests bordering valleys, and big forests near rivers, are the favourite haunts of the typical hornbills. Here the great birds perch in flocks which may number a score in individuals; for hours together they sit motionless, with the neck drawn back on to the body, and the body itself pressed down on to the feet.

Their food consists chiefly of the fruits of the trees in which these birds take up their quarters, the favourite fruit being figs; but in captivity hornbills will eat fruits of all kinds, as well as animal food. These birds kill every small creature that comes in the way, and throw them up in the air before swallowing the body. When perching, hornbills utter from time to time a loud cry, recalling the bark of a dog, this changing into a loud scream when they are wounded.

The most remarkable feature connected with the habits of these birds is, however, connected with their nesting arrangements. As was first observed in India in 1855 by a military officer devoted to outdoor natural history, when the female has laid her clutch of eggs, varying in number from two to half a dozen, in some hole in a tree and commenced to incubate, the male walls up the entrance to the apartment with clay, leaving an aperture only just large enough for her to protrude her beak and receive the food brought regularly by her hard-working mate. The object of this immuring process is doubtless to protect the female and her eggs or young from the attacks of birds-of-prey, or predatory arboreal mammals. Under these circumstances sanitary matters cannot, of course, be attended to, and the nest-hole, consequently, soon becomes an evil-smelling mass of abominable filth. In order that no time may be wasted, the female moults during the period of her confinement, a process which adds still more to the mess in the hole. The young, which come forth from the eggs almost naked, remain in the breeding-hole till they are fully fledged. To reach the food brought by her partner, the female, at any rate during the early stages of incubation, has to climb up to the aperture in the wall of clay.

THE BLUE MACAW

(_Ara cærulea_ or _Ara ararauna_)

The blue, or blue and yellow, macaw, the ararauna of the natives, is one of the most familiar representatives of a group of tropical American parrots characterised by their large size, long tails, and brilliantly coloured plumage, as well as, it may be added, by their atrociously loud, screaming cries, which render them among the most objectionable of all birds as pets. In the species forming the subject of the plate blue and yellow are the predominant hues; yellow, it is said, being the equivalent among true parrots, in which white is unknown, to no colour at all. The whole of the under surface and the sides of the neck are deep orange-yellow, while the upper surface, inclusive of the tail-coverts, is dark sky-blue. The range of this species, like that of its relative the green and blue macaw (_Ara severa_), extends only from Panama southwards through the tropical forests of the New World. Other kinds are, however, found farther north, the handsome red and blue species (_A. chloroptera_) and the red and green macaw (_A. militaris_) extending, for instance, from Mexico and central America to Bolivia. Four other species, known on account of their deep blue colouring, as hyacinthine macaws, constituting the genera _Anodorhynchus_ and _Cyanopsittacus_, are, on the other hand, solely Brazilian.

Macaws are not only strong fliers, but likewise excellent climbers, and in the latter mode of progression make use of their powerful beaks as well as their feet, in captivity, at any rate, frequently hanging from a branch or perch by the beak alone, which is specially adapted for obtaining a hold on smooth branches by the sharp downward curvature of the extremity of its upper half. The food of these birds includes fruits and seeds, especially hard nuts of various kinds, which are cracked in the strong beak as if in a vice. When the fruits or nuts are large, they are held to the beak in one foot. The thick, fleshy tongue aids in extracting the inside of fruits from the rind, or the kernels of nuts from their shells.
