''Alauda'' is a genus of larks with four species found across much of Europe, Asia and in the mountains of north Africa, and one species (the Raso lark) endemic to the islet of Raso in the Cape Verde Islands. These birds are 14–18 cm long and live in cultivation, heath, natural steppe and other open habitats. The long, unbroken song is a clear, bubbling, warble delivered high in the air while the bird is rising, circling or hovering. They are fairly undistinguished: streaked brown above and pale below, with a short, blunt, erectile crest. In flight, they display a short tail and short broad wings. The tail and the rear edge of the wings are edged with white. Their diet consists of seeds, supplemented with insects in the breeding season. They nest on the ground in tufts of grass, with three to six eggs per clutch. They form flocks when not breeding. ==Species in taxonomic order== * Eurasian skylark, ''Alauda arvensis'' * * Japanese skylark, ''Alauda a. japonica'' * Oriental skylark, ''Alauda gulgula'' * Raso lark, ''Alauda razae'' 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「Alauda」の詳細全文を読む スポンサード リンク
