House Finch (Haemorhous mexicanus) is a moderate-sized perching bird in the Finches, Euphonias, and Allies (Fringillidae) family that is 15 cm (5-6 inches) long. 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 are streaked. Adult male heads, necks and shoulders are reddish (sometimes orange-red and occasionally even yellow). This color sometimes extends to the belly 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. It forages on the ground, while perching in weeds, or up in trees and shrubs. Except when nesting, it usually forages in flocks. They will come to feeders for seeds, especially sunflower seeds, and to hummingbird feeders for sugar-water. There are several subspecies.
Diet is mostly seeds, buds, berries. Almost all of diet is vegetable matter. Feeds mainly on weed seeds. Other important items include buds and flower parts in spring, berries and small fruits in late summer and fall. Also eats a few insects, mostly small ones such as aphids.
Young are fed on regurgitated seeds. House Finches feed their nestlings exclusively plant foods, a fairly rare occurrence in the bird world. Many birds that are vegetarians as adults still find animal foods to keep their fast-growing young supplied with protein.
