THE FLAMINGO (Phœnicopterus roseus).
The FLAMINGOES (Phœnicopteri), notwithstanding their extraordinary length of leg and neck, which have induced some authors to class them with the Wading Birds, are, both in their general structure and mode of life, most undoubtedly to be regarded as members of the present order, and are, as their internal anatomy teaches, very nearly related to the Swans. Their body is slenderly built, neck very long, head large, and the wings, in which the second quill is the longest, of moderate length; the tail, which consists of twelve feathers, is remarkably short. The peculiarly constructed beak is somewhat longer than the head, higher than broad, but thick and bent down towards the middle, at an obtuse angle. The upper mandible, which is much smaller and feebler than the lower, is remarkably flat; both mandibles are provided at their circumference with the lamellated sieve-like structure characteristic of the Lamellirostres. The whole apparatus very much resembles a box, of which the lower jaw forms the body, while the upper mandible constitutes the lid. This extraordinary bill is covered with soft skin, but is hard at its apex, and towards its base presents a soft cere. The legs, which are most disproportionately long and slender, are denuded of feathers for a considerable distance above the heel; the three front toes are of moderate length, and connected by a broad, slightly-excavated web. The hind toe, which is considerably elevated, is short and feeble. The thick, compact, soft plumage is beautifully coloured, and is exactly comparable to that of other Swimming Birds. The internal structure of the Flamingo has been carefully studied by Wagner, and found to correspond in every particular with that of the Ducks (Anatidæ). Naturalists are at present acquainted with about half a dozen species belonging to this group, and although the history of some of them is far from complete, enough is known to induce us to believe that in their mode of life they differ in no respect from the species with which we are best acquainted. These remarkable birds are widely distributed over the warmer portions of the globe, and are met with principally in Asia, Africa, and South Europe. According to the accounts of both ancient and modern writers, they make their appearance every year in great numbers in the vicinity of the lakes of Sardinia and Sicily, as also in Albufera de Valencia, and other parts of Spain. Along the coasts of Egypt, Tripoli, Tunis, Algiers, and Morocco, they are abundant, as also in Smyrna, and near the banks of the Volga, but are very rarely met with in Greece. Occasionally a few stragglers have been seen as far north as the banks of the Rhine; generally speaking, however, the south coast of Europe must be regarded as their northern limit, and North Africa and Central Asia as their usual habitat. Those species that inhabit the Western Hemisphere are likewise confined within corresponding limits. Lakes of salt or brackish water in the vicinity of sea-coasts are the favourite resorts of the Flamingoes. To lakes of fresh water they are only casual visitants, and never resort to them for any length of time. On the other hand, they are always very abundant on the sea-coast, more especially where the shores are flat and swampy. All are birds of passage, and the migrations of some occur with such regularity that the period of their return may be predicted with tolerable accuracy. According to Cetti, Flamingoes appear in Sardinia about the middle of August, and depart thence in March or the beginning of April. In South Italy they are stationary, remaining in the same locality all the year round. Only those who have had the good fortune to see these birds assembled in flocks, consisting of many thousands, can form an adequate idea of the beauty of their appearance. "Looking from Cagliari to the sea," says Cetti, "it seemed to be banked in with a wall of red bricks, or to be covered with countless numbers of roses. On nearer approach these proved to be Flamingoes ranged[Pg 117] in regular ranks. Aurora herself was never adorned with more roseate tints than the wings of these birds, they seemed literally to glow with pink and carmine. The name of the Flamingo, both in Greek and Latin, was derived from the magnificent hues of their glorious wings, and the French in the epithet flammant only repeat the same idea. The first impression produced by such a spectacle is not easily to be forgotten; the birds stood in ranks, not merely of thousands, but literally of hundreds of thousands, ranged in interminable array. As the sunlight played upon the dazzling white and glowing red, the effect was indescribable; at length, taking alarm at something, the whole body of them rose into the air, displaying their wings to still greater advantage, as they formed themselves into an immense wedge-shaped phalanx, and winged their way far up into the blue sky." When standing quietly upon the shore, the appearance of these birds very much resembles that of an army drawn up in order of battle; the Cingalese call them "English soldier birds," the South Americans simply "soldiers," and indeed not without cause, for, as Humboldt informs us, the inhabitants of Angostura, soon after the establishment of that colony, were one day thrown into a state of great alarm by the sudden appearance of what they took to be a numerous army, and it was only when the supposed enemy took flight to the shores of the Orinoco, that they discovered their mistake. A solitary Flamingo is very rarely seen, never perhaps before the commencement of the pairing season, and even then it must be some young bird that has strayed by accident from its fellows. Usually they keep together in flocks, and carefully avoid any locality where danger might be apprehended. Open waters are usually selected as their fishing-place, and should a boat approach they at once take flight whilst it is still far off, so that it is by no means easy to observe their proceedings, except with the aid of a telescope. In general they may be seen with their legs immersed in the water, or more rarely on the dry shore or on sandbanks with their necks curved in a very peculiar manner (see page 116) in front of the breast, the head being laid as it were upon the back, or buried beneath the shoulder-feathers of the wing; generally the whole weight of the body is supported by one leg, the other being held obliquely backwards or drawn up close to the body; in this strange position the Flamingo sleeps. The manner in which these birds obtain their food is equally remarkable. Like all other sieve-beaked birds, the materials upon which they subsist are procured by raking in the mud. The Flamingo when in search of food, wades into the water to a convenient depth, and then bends down its long neck until its head is upon the same level as its feet; it then plunges its beak, with the upper mandible downwards, into the mud. In this position the bird rakes about at the bottom of the water, moving backwards and forwards with short steps, and opening and shutting its bill whilst its tongue is busily at work. In this manner, by the delicate sense of touch resident in that member, the Flamingo examines the contents of its mouth, retaining what is useful as food, and straining out through the sieve-like apparatus the mud or non-nutritive materials with which it is accompanied. Meanwhile, by the movements of its webbed feet, it is continually stirring up the bottom, and thus putting in motion all the little aquatic animals of which it is in search. The gait of the Flamingo very much resembles that of the Long-legged Waders, but is not exactly similar, although the difference is not easily described. Its steps are longer, more regular, and more vacillating, as might be expected from the extraordinary length of its legs, but at the same time its movements are easy, and differ widely from the accounts given of them by some writers, who tell us that when walking it is compelled to help itself along by its beak. Its beak, however, is occasionally employed to assist it in its movements, as for example, when having bent its legs under its body it lies down upon the ground to rest, and is suddenly obliged to rise from this position, the bill is employed to assist in getting up, but this once accomplished it runs away with tolerable speed in the manner above described. When taking flight from the sea or lake in which it has been feeding, it not unfrequently goes to a considerable distance, half running and half flying over the surface of the water, much after the manner of a Duck or Water-hen. In deep[Pg 118] water it also swims apparently without the slightest effort, and although its progress may be somewhat slower than that of the Short-legged Swimmers, it is evidently more enduring. Its flight, when once it has raised itself out of the water in the manner above described, is light and tolerably rapid, the quick strokes of its wings producing a noise not unlike that which accompanies the flight of Ducks and Wild Geese, indeed, the sound made by the rising of a whole flock has been compared to distant thunder. When fairly on the wing a flying Flamingo could not be mistaken for any other bird, even by the most unpractised novice. Unlike the generality of long-necked birds, it stretches not only its long legs, but its neck straight out, thus presenting an appearance of extraordinary length and slenderness; so that, with its narrow wings exactly in the centre, it assumes pretty much the shape of a cross. When flying together in considerable numbers, the flock, as we have already said, arrange themselves in regular phalanx, either in one long line, or in a wedge-shape like that of the letter V. When descending from a great height, their flight assumes a spiral direction, but just before alighting they sweep forward for a little distance over the water until they find a suitable spot whereon to settle. The loud harsh voice of these birds somewhat resembles that of a Goose. The food of the Flamingo consists principally of water-snails, worms, crustaceans and small fishes, but it by no means despises vegetable substances, and in a state of captivity will eat boiled rice, corn, or soaked bread. Our information concerning the breeding of these birds is not very satisfactory. Labat many years ago gave a very strange description of their mode of incubation, which was subsequently contradicted by Dampier; and later writers have contented themselves with copying these accounts without ascertaining their accuracy. Dampier informs us that "the Flamingoes build their nests where plenty of dirt is procurable. This dirt they rake together by means of their feet, so as to form a hillock, which stands like a little island, a foot and a half above the water, each hillock being of a conical shape, and having a depression at the top, on which the nest is placed." Labat states that the hillocks are solid, as high as the surface of the water, but that above this point they are hollowed like a basin, and that when the birds lay or incubate their eggs, they place themselves upright, not upon the hillock, but close to it, with their feet upon the ground, in such a manner, that leaning against the hillock they cover the nest with their tail. Naumann in the strongest terms refuses to believe either of the above accounts, and from our own observations on the living birds we ourselves quite acquiesce in the doubts he expresses. It is true we have never seen a Flamingo actually engaged in incubating; but at Mensala, in Egypt, where we obtained a full-grown egg from the oviduct of a dead female, we procured the following information concerning the mode of incubation. The Flamingo makes her nest in shallow places in the water, or, as the Arabs assert, upon flat insular spots, overgrown with low vegetation. In the first case the nest is a conical heap of mud scraped together by the feet of the bird, and raised so high that its top is a foot and a half above the water. In the second case it consists of a mere hollow trough, scooped out in the soil and lined with sedge, rushes, grass, and similar materials. The number of eggs laid is generally two, occasionally three. Their shape is elongated, and their shell smooth and of chalky whiteness. The bird when brooding most undoubtedly sits upon her eggs in the usual manner, bending her legs beneath her, and lying flat upon the nest. The duration of incubation is stated to be from thirty to thirty-two days. The young when hatched immediately betake themselves to the water, and swim from the day of their birth. They soon learn to run, but are not capable of flight till a lapse of several weeks. The chase after Flamingoes requires considerable caution. In the daytime they are so timid that it is almost impossible to get within gunshot of one of their numerous assemblages, seeing that while feeding they invariably station some of the older members of the flock to warn them of the approach of danger. The Arabs informed us, however, that they may be procured in considerable numbers by a very simple contrivance. The plan adopted in Egypt is to suspend ordinary fishing-nets between two boats, and in this manner to sail[Pg 119] directly towards the sleeping-place of the birds; thus suddenly awakened, the Flamingoes fly against the nets, in which they are easily captured, and in this manner fifty or sixty are sometimes taken at once. The fishermen on the Lake of Mensala adopt a still stranger plan: after having, by carefully watching a flock, discovered where the sentinels are placed (the latter always remain bolt upright, whilst the rest of the flock sleep with their heads under their wings), a naked fisherman, having his head covered with a bundle of grass or reeds, swims or creeps towards the unsuspecting birds, and suddenly seizing the sentry, plunges his head under water, and breaks his neck before an alarm can be given. The sleepers then become easy victims. This latter account we should certainly not have credited without corroborative evidence. In North Egypt, however, dozens of these beautiful birds may be seen exposed for sale in the markets, where they are eagerly bought for the table; their flesh is excellent, and quite devoid of the oily flavour which we fully expected would have rendered it unpalatable.
The SWANS (Cygni), from their proud looks and majestic demeanour, must ever hold a conspicuous position in the order to which they belong. Their imposing size and elegant appearance at once rivet attention, and closer examination shows that amongst Lamellirostral birds they form a sharply-defined group, easily distinguishable from the Ducks and the Geese, with which they have been sometimes associated. Their body is elongated, their neck very long, and their head moderate. Their beak is straight, of equal breadth throughout, rounded in front, and at its base naked and protuberant. The upper mandible is flatly vaulted above, and terminates anteriorly in a roundish nail. The length of the beak is pretty nearly the same as that of the head; the legs are short, and placed very far back; the middle toe is longer than the tarsus, and the hinder toe, which is small and feeble, is so much elevated that in walking it does not reach the ground; while the web connecting the three front toes is remarkably broad and complete. In the construction of the wing, the relative proportions between the bony framework and the quills is deserving of notice, the former being very long, the latter somewhat short, while the primary quills, of which the second is the longest, are scarcely longer than the secondaries and the tertiaries. The tail consists of eighteen or twenty graduated feathers. On the under surface the plumage is thick and fur-like; on the upper side, on the contrary, the feathers are broad; but everywhere, both above and below, the body is richly covered with down.
With the exception of the equatorial regions of our globe, Swans are to be met with in every climate, but they principally abound in temperate and cold latitudes. In Asia and Europe three species are met with, which occasionally extend their winter visits as far as North Africa. Two of these species are likewise met with in America, together with several others that are peculiar to that continent; while at least one other very conspicuous species is an inhabitant of Australia. The extent over which these several kinds are spread is very considerable, and their migrations extend over a great distance. All the species are migratory, but by no means all the individuals belonging to each, seeing that there are many of them whose residence is within the limits of the temperate zone, that remain all the year round in the same locality, or at all events, content themselves with wandering to some place not very far remote from their usual residence.
The following interesting account of the migrations of these birds is given by Franklin: "About the first of September the Swans leave the Polar Sea, and resort to the lakes and rivers in and about the latitude of Hudson's Bay; there they remain till October, preparing for their departure for the winter, when they collect in flocks of from twenty to thirty, and seizing a favourable opportunity, with the wind not opposed to the direction of their flight, they mount high in the air, form a prolonged wedge, and with loud screams depart for more genial climes. While making either their semi-annual transmigration, or on shorter expeditions, an occasional scream, equal to, 'How do you all come on[Pg 120] behind?' issues from the leader, which is always replied to by some posterior Swan with an 'All's well!' vociferation. When the leader of the party becomes fatigued with his extra duty of cutting the air, he falls into the rear, and his neighbour takes his place. When mounted, as they sometimes are, several thousand feet above the earth, with their delicate outline scarcely perceptible against the clear blue of heaven, this harsh sound, softened and modulated by distance, and issuing from the immense void above, assumes a supernatural kind of tone."
The permanent habitat of the Swans is always upon large lakes of fresh water, or in marshy situations where fresh water is abundant. During their migrations, however, they take up a temporary residence on water of any kind. Their nests are generally placed on rivers or fresh-water lakes, but probably this is only on account of the shallowness of such situations, as after the breeding season some betake themselves to the sea, or wherever food is most abundantly procurable. The Swans are only active in the day, and even their migrations are never carried on by night. In their locomotive capabilities they surpass most other Swimming Birds. Their domain is the water, and it is only unwillingly that they ever venture on dry land; nor do they readily take wing, unless compelled to do so by unavoidable necessity. The very backward position of their legs renders walking on land difficult, so that when on dry ground their gait is heavy and vacillating. Their flight apparently requires considerable effort, more especially when they attempt to rise from the surface of the water; when, however, they have gained a certain altitude, it is extremely rapid. It would appear almost impossible for these birds to rise from the ground, and they never venture to alight on dry land. When beginning their flight from the water, they always stretch out their necks horizontally to their full length, striking the surface with their wings, and splashing with their broad-soled feet; and thus, half flying and half walking, they proceed for a distance of from forty to eighty feet, before they can acquire impetus to enable them to mount into the air. When, however, this is once accomplished, their movements are perfectly easy and free. When alighting from their flight they glide obliquely downwards to the water, and when they have nearly reached it, spread out their webbed feet to stay their headlong career, and moderate the shock of their descent. As relates to their vocal powers, different species of Swans vary considerably; some appear to be mute, but generally speaking their cry may be said to have somewhat the sound of a trumpet, and much resembles the voice of the Cranes. Some commonly, however, only utter a loud hissing or a low muttering noise; in other species, on the contrary, the voice is loud and powerful, and somewhat varied, so that when heard from a distance its effect is by no means disagreeable. The cry of the male is always louder and of a deeper tone than that of the female. The young "pipe," like young Geese. The manners of Swans are gentle, and rather shy, nevertheless they exhibit a certain degree of vanity and consciousness of power, often manifested in their domineering behaviour towards other Water-fowl. Only those of the same species associate in large numbers, and they seem particularly jealous of intruders. The matrimonial engagements of these birds are kept with exemplary fidelity, and last throughout their lives. No sooner have they paired, than the happy couple begin to show the tenderest affection towards each other, manifested by innumerable graceful caresses; they swim together with indefatigable constancy, and should danger approach defend each other with the utmost courage and self-devotion. Their care for their young progeny is equally remarkable. Although the male does not himself actually take a share in the duties of incubation, all his energies seem to be devoted to the protection of his mate during her patient retirement, and he may at such times always be seen, either swimming proudly and defiantly around her, or reposing in the immediate vicinity of the nest, as though to cheer her confinement by his presence. Although the labour of nidification seems to devolve principally upon the female, she is eagerly assisted by her mate, whose employment seems chiefly to be the procuration of materials, which he supplies abundantly, dragging them with his beak, sometimes from[Pg 121] a considerable distance, or pushing them before him in heaps towards the selected locality. The nest, when completed, is a very large but inartistically constructed pile, composed of all sorts of water plants, confusedly heaped together, but surmounted with a finer covering of sedge grass and other softer materials. The place chosen for the situation of the nest is generally some small island, and its size such that it would float even with the weight of its occupants upon it. In this capacious cradle the female Swan lays from six to eight thick-shelled eggs, of a dirty white, or dirty pale green colour, from which, after the lapse of five or six weeks, the young brood make their escape. When first hatched the Cygnets are pretty little creatures, warmly clad in a thick covering of down; after having remained in the nest for a day or so, they venture out and trust themselves upon the water. Sometimes the mother carries them upon her back, sometimes takes them beneath the shelter of her wings, and always watches over them with the greatest tenderness and anxiety, until they are able to take care of themselves. No sooner, however, are they completely fledged, than they finally separate themselves from their parents, never to see them again; for should they next year make their appearance in the same locality, they would at once be driven away, and treated as any other intruders. The food of the Swans is very diversified, consisting of such vegetables of various kinds as grow in ponds and marshes, roots, leaves, and seeds, beetles and their larvæ, worms, snails, tadpoles, and fishes; anything, in short, that affords nourishment. They are not so strictly vegetable feeders as the Geese, neither are they so carnivorous as the Ducks, but in this respect they seem to occupy a middle position between the two. Their food is principally obtained at the bottom of the pond, which, owing to the length of their necks, they are able to reach, even in water of considerable depth; and here they gather aquatic plants, or, straining the mud through their sieve-like jaws, extract such nutriment as it affords.
