The Barbary falcon (''Falco pelegrinoides'') is a medium-sized falcon about the size of a crow. This bird of prey is mainly resident. ==Description== The Barbary falcon is a bird of semi-desert and dry open hills. It typically lays its eggs in cliff-ledge nests. It is similar to the peregrine falcon, but smaller at 33–39 cm length with a wingspan of 76–98 cm. The female is larger than the male. It resembles its relative in general structure. Adults have paler grey-blue upperparts than the peregrine, and often have a buff wash to the barred underparts, whereas the larger species has a white background color. The nape is rufous, but this is difficult to see. Sexes are similar, apart from size, but the young birds have brown upperparts and streaked underparts. The streaking is lighter than in the juvenile peregrine. The call is a high-pitched "rek-rek-rek". The Barbary falcon also bears some resemblance to the lanner falcon, but can be distinguished from that species at rest by the head-pattern, and in flight, by the proportions, flight action and underwing pattern.〔Clark & Shirihai (1995)〕 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「barbary falcon」の詳細全文を読む スポンサード リンク
