House Finch
Adults have a long, square-tipped brown tail and are a brown or dull-brown color across the back with some shading into deep gray on the wing feathers. Breast and belly feathers may be streaked; the flanks usually are. In most cases, adult males' heads, necks and shoulders are reddish. This color sometimes extends to the stomach and down the back, between the wings. Male coloration varies in intensity with the seasons and is derived from the berries and fruits in its diet.
