Naturalists say that the plumage of this bird differs considerably in summer and winter; though, from analogy with others of its species, I am authorized in suspecting that this change arises rather from age. I shall leave the question undecided; and since we can never see this bird when it has retired in summer within the arctic circle, its native home, I shall content myself with describing its winter colours, such as we may see them in a room. It is the size of a lark, six inches and a half in length, of which the tail measures two and two-thirds. The beak is five or six lines in length, with every characteristic of the bunting species, conical in form, rather bent at the sides, and having a bony tubercle like a grain of barley at the palate; its colour in the singing season is quite black, at other times the point alone is black, the rest yellow. The back and rump are black, the feathers of the back being edged with white, whilst those of the rump and scapulars are edged with yellowish brown, darker in spring than summer. The female is rather smaller, the head and upper part of the neck white, with a mixture of cinnamon-brown, and transverse spots of the same colour form a kind of broken band across the white breast. The young ones which are taken in winter are known by their dark brown beak; the lower part of the back is of the same colour, but their feathers are edged with a light grey. The male has the head most speckled with yellow brown, the cheeks of the female are of the same tint, and it has spots of this on the breast. OBSERVATIONS.--When the winter is severe, these birds are seen from December to May in many parts of Germany, where they even approach the villages. I am persuaded that, if attention were paid to them, they might be seen in every direction, during March, on their passage to the North; whilst snow is on the ground they are found in company with larks, on the high roads and in the fields; they may then be taken with horse dung, placed in net, or covered with bird-lime, or by clearing a spot of ground of snow and strewing it with oats. I have had a pair six years in my room without a cage, and they are satisfied with the food common for other birds: if kept in a cage, they must be fed on hemp seed, oats, millet, rape, and poppy seeds. They appear much delighted whilst bathing; during the night they seem very uneasy, hopping and running about continually. Their strong and piercing cry resembles a loud whistle; their song would be rather agreeable were it not interrupted in a peculiar manner; it is a warbling mingled with some high noisy notes, descending slowly from shrill to deep, and a little strong and broken whistling. Heat is so contrary to their nature, that they cannot be preserved unless carefully guarded from it. THE MOUNTAIN BUNTING.
