Purple Finch

Identification

The purple finch is 12–16 cm (4.7–6.3 in) in overall length and weighs a mean 23.3 g (0.82 oz), ranging from 19.8–28.4 g (0.7 - 1.0 oz). It has a short forked brown tail and brown wings. Adult males are raspberry red on the head, breast, back and rump; their back is streaked. Adult females have light brown upperparts and white underparts with dark brown streaks throughout; they have a white line on the face above the eye.<p>The subspecies H. p. californicus differs from the nominate in having a longer tail and shorter wings. The plumage of both males and females is darker, and the coloration of the females is more greenish. It also has a longer bill.

Taxonomy

The purple finch was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with the finches in the genus Fringilla and coined the binomial name Fringilla purpurea. Gmelin specified the locality as Carolina. Gmelin based his account on the "purple finch" that had been described and illustrated by the English naturalist Mark Catesby in his book The Natural History of Carolina, Florida and the Bahama Islands. The purple finch is now one of three finches placed in the genus Haemorhous that was introduced in 1837 by the English naturalist William Swainson.<p>Two subspecies are recognised:<p>This species and the other "American rosefinches" were formerly included with the rosefinches of Eurasia in the genus Carpodacus; however, the three North American species are not closely related to the rosefinches of the Old World, and have thus been moved to the genus Haemorhous.

Range and habitat

Their breeding habitat is coniferous and mixed forest in Canada and the northeastern United States, as well as various wooded areas along the U.S. Pacific coast.<p>Birds from northern Canada migrate to the southern United States; other birds are permanent residents.[citation needed]<p>The purple finch population has been displaced from some breeding season habitats in the Eastern United States following the introduction of the house finch, which is native to the western U.S. and Mexico. The two species share a similar niche, with the house finch often outcompeting the purple finch during the summer.

Complete migrants

Behavior

These birds forage in trees and bushes, sometimes in ground vegetation. They mainly eat seeds, berries, and insects. They are fond of sunflower seeds, millet, and thistle.<p>The purple finch prefers nesting in lowland coniferous and mixed forests, avoiding more heavily populated urban areas, but sometimes found in rural residential areas. The female Purple Finch usually builds her nest on horizontal branches of coniferous trees, away from the trunk, but occasionally in tree forks. The nest is shaped like an open cup, made up of rootlets, twigs, and weeds, and lined with grass, hair, and moss.
