Tyrant flycatchers are Passerine birds which occur throughout North and South America. They superficially resemble the Old World flycatchers, but are more robust and have stronger bills. They do not have the sophisticated vocal capabilities of the songbirds. Most, but not all, are rather plain. As the name implies, most are insectivorous.
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 American Federation of Aviculture, Inc. (AFA) is a national organization dedicated to aviculture, whose purpose is to educate the public and assist members regarding best practices for keeping and living with exotic birds.
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 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]
The family Fringillidae are the "true" finches. The International Ornithological Committee (IOC) recognizes these 239 species in the family, distributed among three subfamilies and 50 genera. Confusingly, only 79 of the species include "finch" in their common names, and several other families include species called finches.

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.
