The black-thighed falconet (''Microhierax fringillarius'') is one of the smallest birds of prey, typically measuring between long, with a wingspan, which is a size comparable to a typical sparrow.〔Raptors of the World by Ferguson-Lees, Christie, Franklin, Mead & Burton. Houghton Mifflin (2001)828-829, ISBN 0-618-12762-3〕 It is native to Brunei Darussalam, Myanmar, Thailand, Malaysia, Singapore and Indonesia.〔 ==Description== This is a minute, shrike-like falcon, with a squarish tail that is frequently spread. The adult male is glossy black above, with a white forehead streak that arcs around black cheeks. It has a white or rufous-washed throat, with a white breast shading into a rufous abdomen. Its thighs and flanks are black, as is its cere and legs. In flight the male has white wings underneath with black barring on the primaries and secondary flight feathers, and light streaking on the underwing coverts. There are three white bars underneath on the otherwise plain black tail. The adult female is similar to the adult male, except the tail is longer. The juvenile is similar to the adults, except that the white areas of the head are rufous.〔〔 〕 The voice is a hard, high-pitched cry ''shiew'' and a fast repeated ''kli-kli-kli-kli''.〔 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「Black-thighed falconet」の詳細全文を読む スポンサード リンク
