Together with its relatives the American goldfinch and Lawrence's goldfinch, it forms a clade, termed the 'New World goldfinch' clade, in the genus Spinus. Some authors have suggested treating this clade as a separate genus Astragalinus , [ 2 ] but this has not been followed by either the IOC or BirdLife International.
The only finch in its subfamily to undergo a complete molt, the American goldfinch displays sexual dichromatism: the male is a vibrant yellow in the summer and an olive color during the winter, while the female is a dull yellow-brown shade which brightens only slightly during the summer.
The eggs are incubated for 11–13 days by the female, who is fed by the male. The chicks are fed by both parents. Initially they receive a mixture of seeds and insects, but as they grow the proportion of insect material decreases. [25] For the first 7–9 days the young are brooded by the female. The nestlings fledge 13–18 days after hatching.
A flying paradox, the house finch is both native and introduced to North America. Originally native to Mexico and the Western United States, house finches were shipped to New York City and sold as ...
The male has a red crest and a black crown, just as the grey pileated finch does, however its upper parts are dark wine red, with a reddish rump, and the underparts are a drab reddish colour.

The male is brightly coloured with a blue-grey cap and rust-red underparts. The female is more subdued in colouring, but both sexes have two contrasting white wing bars and white sides to the ...
Of Cactornis, the two species may be often seen climbing about the flowers of the great cactus-trees; but all the other species of this group of finches, mingled together in flocks, feed on the dry and sterile ground of the lower districts. The males of all, or certainly of the greater number, are jet black; and the females (with perhaps one or ...
The purple finch was designated the state bird of New Hampshire in 1957. [13] The New Hampshire red hen (breed of domestic chicken) was also proposed, but was not chosen in favor of the purple finch. [14] In 1763, Richard Brookes made the description of the female purple finch in Mexico with the name of "chiantototl" (chia seed bird). [15]
