Adaptable, colorful, and cheery-voiced, House Finches are common from coast to coast today, familiar visitors to backyard feeders. Native to the Southwest, they are recent arrivals in the East. New York pet shop owners, who had been selling the finches illegally, released their birds in 1940 to escape prosecution; the finches survived, and began to colonize the New York suburbs. By 50 years later they had advanced halfway across the continent, meeting their western kin on the Great Plains.

A typical summer sight is a male American Goldfinch flying over a meadow, flashing golden in the sun, calling perchickory as it bounds up and down in flight. In winter, when males and females alike are colored in subtler brown, flocks of goldfinches congregate in weedy fields and at feeders, making musical and plaintive calls. In most regions this is a late nester, beginning to nest in mid-summer, perhaps to assure a peak supply of late-summer seeds for feeding its young.

Not really purple, more of an old-rose color is the male Purple Finch. This species is common in the North and East, and along the Pacific seaboard, but it is very rare in much of the Rocky Mountains region. Purple Finches feed up in trees and on the ground in open woods. They readily come to bird feeders; but they have become less numerous as feeder visitors in the Northeast, where competition with introduced House Sparrows and then House Finches may have driven them back into the woods.

This chunky, big-billed finch wanders widely in winter, descending on bird feeders in colorful, noisy flocks, to thrill feeder-watchers and to consume prodigious amounts of sunflower seeds. Originally a western bird, almost unknown east of the Great Lakes before the 1890s, it now breeds commonly east to New England and the Maritime Provinces. Its eastward spread may have been helped by both the planting of box elders (a favorite food tree) across northern prairies, and the abundance of bird feeders in the Northeast.

One of the 'winter finches,' nesting in the Arctic and sometimes invading southern Canada and the northern states. Redpolls are tiny, restless birds, feeding actively on seeds among trees and weeds, fluttering and climbing about acrobatically, their flocks seemingly always on the move. For their small size, they have a remarkable ability to survive cold temperatures; their southward flights are sparked by temporary scarcity of food in the North, not by cold. At bird feeders in winter, redpolls are often remarkably tame.

Although it is patterned like a sparrow, its shape, actions, and callnotes all reveal that this bird is really a goldfinch in disguise. After nesting in the conifer woods, Pine Siskins move out into semi-open country, where they roam in twittering flocks. They often descend on fields of thistles or wild sunflowers, where they cling to the dried flower heads, eating seeds. In winter they sometimes invade southward in big numbers, with flocks coming to feeders along with American Goldfinches.

Very common in parts of the West, this tiny finch is easy to overlook until one learns its chiming and twittering callnotes. Small flocks of Lesser Goldfinches are often found feeding in weedy fields or in streamside trees. Two color patterns occur in the United States, and males in some areas may be either green-backed or black-backed. The complicated song of the male usually includes short imitations of the voices of other birds.

A big boreal finch, uncommon but widespread in spruce and fir forests of the North and the high mountains. It is often absurdly tame, allowing very close approach; ironically, this sometimes makes it easy to overlook in dense coniferous forest, since it may sit motionless as a birder walks by. On those occasions when Pine Grosbeaks move south in winter, they may be more conspicuous, often feeding on buds in the bare branches of maples or other trees.
