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. [11]
The house finch is a moderate-sized finch, 12.5 to 15 cm (5 to 6 in) long, with a wingspan of 20 to 25 cm (8 to 10 in). Body mass can vary from 16 to 27 g (9 ⁄ 16 to 15 ⁄ 16 oz), with an average weight of 21 g (3 ⁄ 4 oz).
Within the genus the House Finch is the outgroup, meaning the Purple and Cassin's finches are more closely related to one another than either is to the House Finch. [ 5 ] Species
The family Fringillidae are the "true" finches. The International Ornithological Committee (IOC) recognizes these 238 species in the family, distributed among three subfamilies and 50 genera. Confusingly, only 78 of the species include "finch" in their common names, and several other families include species called finches.
[1] [2] The last state to choose its bird was Arizona in 1973. Pennsylvania never chose an official state bird, but did choose the ruffed grouse as the state game bird. [3] Alaska, California, and South Dakota permit hunting of their state birds.
They found that the three North American rosefinches, namely Cassin's finch, purple finch, and house finch, formed a separate clade that was not closely related to the Palearctic rosefinches. They proposed moving the three species to a separate genus Haemorhous . [ 7 ]
Weight: 0.8–1.2 oz (24–34 g) Wingspan: 9.8–10.6 in (25–27 cm) Adults have a short forked brown tail and brown wings. They have a longer bill than the purple finch. Adult males are raspberry red on the head, breast, back and rump; their back and undertail are streaked. Adult females have light brown upperparts and light underparts with ...
A potential confusion species also is the female purple finch (Haemorhous purpureus), but that species is noticeably smaller with a less robust bill and a notched tail. [19] The song is a subdued mellow warbling, resembling a more refined, sweeter version of the American robin's (Turdus migratorius). Males start singing early, occasionally even ...
