The Guianan gnatcatcher (''Polioptila guianensis'') is a species of bird in the Polioptilidae family. It is found in the canopy in the Amazon Rainforest. This relatively plain gnatcatcher includes three subspecies, each sometimes considered a species: * Guianan gnatcatcher, ''Polioptila (guianensis) guianensis'', from the Guianas and north-eastern Brazil (north of the Amazon River and east of the Branco River). * Rio Negro gnatcatcher, ''Poliptila (guianensis) facilis'', from southern Venezuela and north-western Brazil (north of the Amazon River and west of the Branco River). * Para gnatcatcher, ''Polioptila (guianensis) paraensis'', from the southern Amazon in Brazil (south of the Amazon River). Additionally, the highly threatened Iquitos Gnatcatcher is associated with this group, though all major authorities recognized it as a separate species. ==References== 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「Guianan gnatcatcher」の詳細全文を読む スポンサード リンク
