The house finch [Haemorhous mexicanus] is a bird in the finch family Fringillidae. It is found in North America, where its range has increased since the mid-twentieth century, and in the islands of Hawaii.
These birds are mainly permanent residents throughout their range; some northern and eastern birds migrate south. Their breeding habitat is urban and suburban areas in eastern North America as well as various semi-open areas in the west from southern Canada to northern Florida and the Mexican state of Oaxaca.
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 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. As a result, the colors range from pale straw-yellow through bright orange [both rare] to deep, intense red.
