The male is brightly coloured with a blue-grey cap and rust-red underparts. The female is much duller in colouring but both sexes have two contrasting white wings-bars and white sides to the tail. The male bird has a strong voice and sings from exposed perches to attract a mate. The chaffinch breeds in much of Europe, across Asia to Siberia and in northwest Africa. It prefers open woodland and often forages on the ground. The female builds a nest with a deep cup in the fork of a tree. The clutch is typically 4–5 eggs, which hatch in about 13 days. The chicks fledge in around 14 days but are fed by both adults for several weeks after leaving the nest. The chaffinch is a partial migrant; birds breeding in warmer regions are sedentary while those breeding in the colder northern areas of its range winter further south. ==Taxonomy== The chaffinch was described by Linnaeus in 1758 in the 10th edition of his ''Systema Naturae'' under its current binomial name. ''Fringilla'' is the Latin word for a finch while ''coelebs'' means unmarried or single. Linnaeus remarked that during the Swedish winter, only the female birds migrated south through Belgium to Italy. The English name comes from the Old English ''ceaffinc'', where ''ceaf'' is "chaff" and ''finc'' "finch".〔(【引用サイトリンク】title=Chaffinch )〕 The finch family, Fringillidae, is divided into two subfamilies, the Carduelinae, containing around 28 genera with 141 species and the Fringillinae containing a single genus, ''Fringilla'', with 3 species: the chaffinch (''Fringilla coelebs''), the blue chaffinch (''Fringilla teydea''), and the brambling (''Fringilla montifringilla''). The finch family are all seed-eaters with stout conical bills. They have similar skull morphologies, nine large primaries, twelve tail feathers and no crop. In all species the female bird builds the nest, incubates the eggs and broods the young. Fringilline finches raise their young almost entirely on arthropods while the cardueline finches raise their young on regurgitated seeds. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「common chaffinch」の詳細全文を読む スポンサード リンク
