词条 | finch |
释义 | finch bird any of several hundred species of small conical-billed, seed-eating songbirds (songbird) (order Passeriformes (passeriform)). Well-known or interesting birds (bird) classified as finches include the bunting, canary, cardinal, chaffinch, crossbill, Galapagos finch, goldfinch, grass finch, grosbeak, sparrow, and weaver. ![]() ![]() Finches are generally excellent singers. However, their songs can range from the complex and beautiful repertoires of the song sparrow (Melospiza melodia) to the monotonously unmusical notes of the grasshopper sparrow (Ammodramus savannarum). Many kinds of finches are kept as cage birds. The nesting (nest) habits of finches are not unusual. The females of most species build a cup-shaped nest of twigs, grasses, and roots on the ground or in bushes and lay four or five eggs (egg). Sometimes the female incubates them alone, but usually the male assists in raising the young. Two or three broods may be raised in a season. Finches generally nest in scattered pairs, but they are highly gregarious at other times and are often seen in large flocks. Formerly, finches were classified in the families Fringillidae, Emberizidae, Estrildidae, and Carduelidae, although authorities disagreed as to which finchlike birds should be classified in each family. Today, most taxonomists and birders classify finches as members of the family Fringillidae. |
