Cassin's Finch

 ♂ Cassin's Finch, Haemorhous cassinii
Cassin's finch is a small rosy-tinged songbird found within the mountains of western North America. Though similar in appearance to house finches and purple finches, Cassin's finch is larger with whiter bellies, peaked head shape, and thick, straight-edged bill. While both male and female Cassin's finches have thin, white eyerings, males are more rosy with an intense red crown whereas females and immatures are more brown and white. Their range and environment also differ with Cassin's finch prefering conifer forests. They are semicolonial with nests sometimes built within close proximity to each other, but often it is only tolerated if nesting time is far enough apart. While their diet is mostly of seeds, insects and fruit are also consumed. They are categorized as a Near Threatened species, but the factors leading to population decline have not yet been identified.
