The MOUNTAIN or GREY LINNET (_Cannabina montium_) in many northern countries seems to take the place of the species just described. Its length is four and three-quarter inches, and the span of its wings eight and a quarter inches. The plumage on the back is of a blackish brown, the feathers being edged with rust colour, the rump is red, the breast of a rusty yellowish grey striped with brown, and the remainder of the lower part of the body white. This bird is always to be met with in the northern parts of Scotland, also in Norway, Lapland, Russia, and Siberia; it inhabits mountain regions where stunted shrubs and low Alpine plants sprout from between the rocks. In its habits it resembles its congeners, but is perhaps of a somewhat livelier and more cautious disposition. Its voice reminds us of the notes of the Siskin and Red Linnet, and though its song can scarcely be called beautiful, it has something so spirited and cheerful in its tones that the inhabitants of such northern countries as are not much frequented by Finches take great pleasure in listening to its strains. In captivity the habits of the Grey Linnet are the same as those of others of its race, and it soon becomes accustomed to a cage. The food of this little chorister consists of seeds. The Mountain Linnet is frequently found in the southern parts of Sweden; it is said to be rare in Scotland though common in England, and is frequently caught in the vicinity of London. Solitary birds of this species are often met with in Germany; and during very severe winters they will even wander as far as Southern Switzerland, Northern Italy, or the south of France. * * * * * Many small Finches, distinguished for their long and slender beaks, were formerly classed under the general name of Siskins, but have lately been arranged in separate groups with more or less reference to the colour of their plumage.
