This bird is rather larger than the chaffinch, being six inches in length, of which the tail measures two and a half; the beak five lines in length. The iris is dark brown; the shanks are eight inches in height, and of a bluish flesh colour. The prevailing colour of the plumage is yellowish green, lighter on the lower part of the body, still more so on the rump and breast, and shading to white on the belly. The female, which is smaller, is still more distinguished by the greenish brown of the upper part, and the ash-colour rather than yellowish green of the lower part of the body; she has besides some yellow spots on the breast, and the whole belly is rather white than yellow. Sportsmen and bird-catchers mention three kinds of green birds, namely, the large, which is everywhere of a beautiful yellow; the middle sized, the under part of the body of which is light yellow; and the little, which they say is rather greenish than yellow; but all this variety depends upon the different ages of the bird, as well as its strength, and more or less beautiful tints of its plumage. What much more deserves to be remarked is the mule, which is the offspring of a green bird, and a female canary; it has a strong body; its colours are green and grey, mixed with yellow, when the female canary is yellow; but it is always a bad singer. HABITATION.--When wild, the green bird may be found over all Europe, though not often far north. It may be seen during summer, in hedges, and on the borders of woods, and always where there are several trees near together; during winter it wanders into different provinces, in large and numerous flocks; but in March it begins to return from these journeys. In the house it may either be let range free, or be shut up in an aviary with other birds, where it is always very peaceable as long as it has sufficient food; but when that fails, it perches itself on the general food-drawer, and keeps it determinedly, pecking it with its beak so cleverly that no other bird can approach: should one venture, it is soon obliged to go away or lose its feathers; otherwise this bird is as quiet and tame in the house as it is wild and active when at liberty. FOOD.--In its wild state it seems to like all kinds of seed, even that of the milk thistle, which all other birds dislike. In the house, when it ranges at will, the second universal paste so well agrees with it that it becomes quite fat; however, as a variety, rape and hemp seed may be thrown to it; if in a cage it must only be fed in summer with rape seed, except a little hemp seed, which may be given after moulting, to make it sing. Lettuce, chickweed and other green food, always agree with it, and even the berries of the juniper tree.
