MODE OF TAKING.--As soon as this bird arrives in May, the bushes on which it most frequently perches must be observed; these are very few, and on them the lime twigs must be placed; it is often entrapped within a quarter of an hour. Success is more certain if a beetle, maybug, or breeze-fly, be fastened near the lime twigs with horse hair, by two feet, so that it can move its wings. As soon as the bird is stuck in the bird-lime it is necessary when taking it to avoid its beak, as it pecks very hard. ATTRACTIVE QUALITIES.--This bird does not rank low among the singers; its song is not only very pleasing but continual. While singing, it is generally perched on a lonely bush, or on the lower branches of a tree, but always near its nest. Its warbling is composed of the songs of the swallow, goldfinch, fauvette, nightingale, red-breast, and lark, with which, indeed, it mixes here and there some of its own harsh notes. It almost exclusively imitates the birds in its immediate neighbourhood; it very rarely repeats the song or call of those which merely fly past it; when it does, it seems only in mockery. There are, however, some songs which it cannot imitate: for instance, that of the chaffinch and yellowhammer, its throat not seeming to be sufficiently flexible for these. In the house, its song is composed of the warbling of those birds whose cages are hung near it. It is very lively, and its plumage is handsome. If a room is to be cleared of flies, one of these birds set at liberty in it will soon effect it; it catches them flying with great skill and agility. When a thorny branch is given it, it impales all its flies, making at the same time the drollest and most singular movements. This species easily and quickly learns to whistle airs, but it forgets them with the same facility, in order to learn new ones. THE RAVEN. [Illustration] Corvus Corax, LINNÆUS; Le Corbeau, BUFFON; Der Kolkrabe, BECHSTEIN. This and the three following species ought not to be reckoned among house birds; but as they are easily taught to speak, and are often reared for that purpose, I must not neglect to mention them here. The raven is well known. Its length is two feet, of which the tail measures eight inches and three quarters. The colour, which is black, in particular lights reflects a violet tint on the upper, and green on the lower part of the body, of the wings and tail. The throat is of a paler black.
