Goldfinches, genus Astragalinus, named for the bright yellow markings of the male, are found in Europe and North America. The common American goldfinch, A. tristis (thistle bird, wild canary, or yellow bird), is a year-round resident everywhere on the North American continent except in the far north. There are several Western species. The British goldfinch is cinnamon brown with black and yellow wings and a red face. Goldfinches are cheerful, musical birds, although the so-called goldfinches commonly kept as cage birds are finchlike members of the weaverbird family. The European bullfinch, with blue-gray plumage above and terra-cotta below, is often caged; it can be taught to mimic tunes. The chaffinch, Fringilla coelebs, also popular in Europe as a cage bird, is similarly marked but with a chestnut back and wings and tail. In North America the sparrowlike eastern purple finch, Carpodacus purpureus (actually rose-brown), has been largely driven out by the house sparrow. There are several purple finches in the West, where the house finch, or linnet, is common. The rosy finches are western mountain dwellers. The house finch, Carpodacus mexicanus, known for its lilting song, was introduced to the eastern states from the West in the 1940s. In the Midwest the dickcissel, which winters in Central and South America, is valued as a destroyer of grasshoppers. Several longspurs, genus Centrophanes, are found from the Great Plains northward; the Lapland longspur is a European finch that ranges to the NE United States. The redpolls, genus Aegiothus, are northern finches that winter in the N United States; with the pine siskins, goldfinches, and various other seedeaters they wander around the country in small flocks, often congregating at feeding stations. The grassquits, genus Phonipara, are native to the Bahamas and Cuba; the brambling, or mountain, finch is a N Eurasian bird that winters in the British Isles.
