One of the first to split off were the ancestors of the North American species and diverged in the Middle Miocene (about 14–12 mya) from the proto-rosefinches. [ 4 ] 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.
The pine grosbeak (Pinicola enucleator) is a large member of the true finch family, Fringillidae.It is the only species in the genus Pinicola.It is found in coniferous woods across Alaska, the western mountains of the United States, Canada, and in subarctic Fennoscandia and across the Palearctic to Siberia.
The house finch may be infected by several parasites including Plasmodium relictum [23] and Mycoplasma gallisepticum, which caused the population of house finches in eastern North America to crash during the 1990s. [24] The mite Pellonyssus reedi is often found on house finch nestlings, particularly for nests later in the season. [25]

The true finches are small to medium-sized passerine birds in the family Fringillidae. Finches generally have stout conical bills adapted for eating seeds and nuts and often have colourful plumage. They occupy a great range of habitats where they are usually resident and do not migrate. They have a worldwide native distribution except for ...
The breeding season begins later in the year than for any other finch and later than any other native North American bird, besides occasionally the sedge wren. [13] [26] This may be related to the abundance of seeds in the late summer months, as seeds represent most of their diet. [27]
Lawrence's goldfinch is known for its wandering habits. It breeds from about Shasta County, California to northern Baja California, largely in the Coast Ranges and the foothills of the Sierra Nevada and in the Baja highlands, but also sometimes as far down as the coast; its highest breeding altitude is about 8,800 ft (2,700 m) on Mount Pinos.
The black rosy finch was first classified by American ornithologist Robert Ridgway in 1874. [1] This bird has been thought to form a superspecies with the three other rosy finches: grey-crowned rosy finch (L. tephrocotis) and the brown-capped rosy finch (L. australis), all of which were classified as the same species as the Asian rosy finch (L. arctoa) from 1983–1993.
