''Anorrhinus'' is a genus of hornbills (family Bucerotidae) found in forests of Southeast Asia (just barely extending into adjacent parts of India and China). They are social and typically seen in groups, but only the dominant pair are believed to breed, while other group members act as helpers. ==Taxonomy== This genus is sometimes limited to the bushy-crested hornbill, in which case the two remaining species, which are sometimes considered conspecific, are placed in the genus ''Ptilolaemus''. * Austen's brown hornbill, ''Anorrhinus austeni'' * Tickell's brown hornbill or rusty-cheeked hornbill, ''Anorrhinus tickelli'' * Bushy-crested hornbill, ''Anorrhinus galeritus'' 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「Anorrhinus」の詳細全文を読む スポンサード リンク
