The genus Fringilla contains the typical Finches such as the Chaffinch and Brambling. In this genus the plumage is of many colours and the Summer and "Winter plumages are very different owing to abrasion of the coloured edges to the feathers. The bill is long and straight, except at the tip, and fairly stout. The tail is very slightly forked and the wings long with the second, or second and third, primary longest.
