The tiny hawk is a small diurnal bird of prey found in or near forests, primarily humid, throughout much of the Neotropics. It is primarily a bird-eater, and is known to prey on hummingbirds. Usually named ''Accipiter superciliosus'', it is the only species of the genus ''Accipiter'' yet studied which has a large procoracoid foramen. It also differs from the typical sparrowhawks in other respects of its anatomy and in its DNA sequence. Consequently, its old name ''Hieraspiza superciliosa'' may be more appropriate. ==Taxonomy== There are two subspecies of tiny hawk, separated by the northern Andes. The two differ most significantly in relative tail length; differences in size and color are small, and can be hard to distinguish.〔 *''A. s. superciliosus'' is found east of the Andes in South America. Slightly the larger of the two subspecies, it is paler and has diffuse, grayish barring on the underparts. *''A. s. fontanieri'' is found from Nicaragua down to western Ecuador. It is somewhat smaller and darker than the nominate ''A. s. superciliosus'', with a shorter tail and sharper, blacker barring below. The tiny hawk and its sister species, the upland-dwelling semicollared hawk (''"A." collaris''), form a superspecies. 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「Tiny hawk」の詳細全文を読む スポンサード リンク
