''Elanus'' is a genus of bird of prey in the elanid kite subfamily. It consists of four species. * Black-winged kite, ''Elanus caeruleus'' * Black-shouldered kite, ''Elanus axillaris'' * White-tailed kite, ''Elanus leucurus'' * Letter-winged kite, ''Elanus scriptus'' The first three species above were considered conspecific as subspecies of ''Elanus caeruleus'', which has been known as the black-shouldered kite. These are white and grey raptors of open country, with black wing markings and a short square tail. They hunt by slowly quartering the habitat for rodents and other small mammals, birds and insects, sometimes hovering like a kestrel. ==References== *Ferguson-Lees, Christie, Franklin, Mead and Burton Raptors of the World ISBN 0-7136-8026-1 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「Elanus」の詳細全文を読む スポンサード リンク
