At the setting in of frosty weather the wild swans are said to associate in prodigious multitudes, and thus united, to use every effort to prevent the water from freezing: this they accomplish by the continual stir kept up amongst them; and by constantly dashing it with their extended wings, they are enabled to remain as long as it suits their convenience, in some favourite part of a lake or river which abounds with their food.
The swan is very properly entitled the peaceful monarch of the lake: conscious of his superior strength, he fears no enemy, nor suffers any bird, however powerful, to molest him; neither does he prey upon any one. His vigorous wing is as a shield against the attacks even of the eagle, and the blows of it are said to be so powerful as to stun or kill the fiercest of his foes. The wolf or the fox may surprise him in the dark, but their efforts are vain in the day. His food consists of the grasses and weeds, and the seeds and roots of plants which grow on the margin of the water, and of the myriads of insects which skim over, or float on its surface; also occasionally of the slimy inhabitants within its bosom.
The female makes her nest of the withered leaves and stalks of reeds and rushes, and lays commonly six or seven thick-shelled white eggs: she is said to sit upon them six weeks before they are hatched. Both male and female are very attentive to their young, and will suffer no enemy to approach them.
Wild Swan. (Anas Cygnus ferus, Linn.; Le Cygne Sauvage, Buff.)—Measures five feet in length, and above seven in breadth, and weighs from thirteen to sixteen pounds. The bill is three inches long, of a yellowish white from the case to the middle, and thence to the tip, black; the bare space from the bill over the eye and eyelids is yellow; the whole plumage in adult birds is of a pure white, and, next to the skin, they are clothed with a thick fine down; the legs are black.
This species generally keep together in small flocks, or families, except in the pairing season, and in the setting in of winter. At the latter period they assemble in immense multitudes, particularly on the large rivers and lakes of the thinly inhabited northern parts of Europe, Asia, and America: but when the extremity of the weather threatens to become insupportable, in order to shun the gathering storm, they shape their course high in air, in divided and diminished numbers, in search of milder climates. In such seasons they are not uncommonly seen in various parts of the British isles, and in other more southern countries of Europe. The same is observed of them in the North American states. They do not, however, remain longer than till the approaching of the spring, when they again retire northward to the arctic regions to breed. A few, indeed, drop short, and perform that office by the way, for they are known to breed in some of the Hebrides, the Orkney, Shetland, and other solitary isles; but these are hardly worth notice: the great bodies of them are met with in the large rivers and lakes near Hudson’s Bay, and those of Kamtschatka, Lapland, and Iceland. They are said to return to the latter place in flocks of about a hundred at a time in the spring, and also to pour in upon that island from the north, in nearly the same manner, on their way southward in the autumn.
Swan-Goose. (Anas Cygnoides, Linn.; L’Oie de Guinée, Buff.)—This species is more than a yard in length, and is of a size between the swan and the common-goose; it is distinguished from others of the goose tribe by its upright and stately deportment, by having a large knob on the root of the upper mandible, and a skin, almost bare of feathers, hanging down like a pouch, or a wattle, under the throat; a white line or fillet is extended from the corners of the mouth over the front of the brow; the base of the bill is orange; irides reddish-brown; a dark-brown or black stripe runs down the hinder part of the neck, from the head to the back; the fore part of the neck, and the breast, are yellowish-brown; the back, and all the upper parts, brownish-grey, edged with a lighter colour; the sides, and the feathers which cover the thighs, are clouded with nearly the same colours as the back, and edged with white; belly white; legs orange.
It is said that these birds originally were found in Guinea only; the breed has, however, now become pretty common, and they are widely dispersed, in a wild as well as a domesticated state, over various parts of the world, both in warm and in cold climates.
They are found wild about the lake Baikal, in the east of Siberia, and in Kamtschatka; and they are kept tame in most parts of the Russian empire.
These geese, like others of the tame kind, vary much both in colour of the bill, legs, and plumage, as well as in size; but they all retain the knob on the base of the upper mandible, and the pouch or wattle under the gullet.
