The length of the blackbird, or ouzel, (_Turdus Merula_, LINN.—_Le Merle_, BUFF.) is generally about ten inches. Its plumage is altogether black; the bill, inside of the mouth, and edges of the eye-lids, are yellow, as are also the soles of the feet; the legs are of a dirty yellow. The female is mostly brown, inclining to rust colour on the breast and belly; the bill is dusky, and the legs brown; its song is also very different, so that it has sometimes been mistaken for a bird of a different species. The males, during the first year, resemble the females so much, as not easily to be distinguished from them; but, after that, they assume the yellow bill, and other distinguishing marks of their kind. The blackbird is a solitary bird, frequenting woods and thickets, chiefly of evergreens, such as holly, pines, firs, &c., especially where there are perennial springs, which together afford it both shelter and subsistence. Wild blackbirds feed on berries, fruits, insects, and worms; they never fly in flocks like thrushes; they pair early, and begin to warble nearly as soon as any other of the songsters of the grove. The female builds her nest in bushes, or low trees, and lays four or five eggs, of a bluish green colour, marked irregularly with dusky spots. The young birds are easily brought up tame, and may be taught to whistle a variety of tunes; for which their clear, loud, and melodious tones are well adapted. They are restless and timorous birds, easily alarmed, and difficult of access. But Buffon observes, that, “they are more restless than cunning, and more timorous than suspicious, as they readily suffer themselves to be caught with bird-lime, nooses, and all sorts of snares.” They are never kept in aviaries; for, when shut up with other birds, they pursue and harass their companions in slavery unceasingly: for which reason they are generally confined in cages apart. In some counties of England, this bird is called simply the Ouzel.—_Bewick._ BLACKCAP, _s._ A small singing bird. BLACK COCK, _s._ (_Tetrao tetrix_, LINN.) Known also as the heath-cock and heath-poult. This species sometimes weighs as much as four pounds; length about twenty-three inches, bill dusky, irides hazel; the head, neck, and whole body, are of glossy blue-black, particularly about the neck, breast, and rump; over the eye the bare scarlet skin is granulated; the coverts of the wings dusky brown, the four first quill feathers black, the next white at the bottom, the lower half and tips of the secondaries white, under wing coverts white; the thighs are dark brown, sometimes marked with a few white spots; the tail consists of sixteen black feathers; the exterior ones bend outwards, and are much longer than those in the middle, which makes the tail very forked; the under tail coverts pure white; legs covered with hair-like feathers of a dark brown, speckled with grey; toes pectinated.
