The long-tailed hawk (''Urotriorchis macrourus'') is a bird of prey in the family Accipitridae, which also includes many other diurnal raptors such as kites, eagles and harriers. It is the only member of the genus ''Urotriorchis''.〔Ferguson-Lees & Christie (2001). ''Raptors of the World.'' Christopher Helm, London. ISBN 0-7136-8026-1〕 This hawk inhabits the tropical rainforests of western and central Africa. It has a wingspan of and a total length of , including the tail of .〔 Females are about 15% larger than males.〔 Since the tail comprises about 56% of this raptor's total length, this species ties with the cinereous harrier as the raptor with the longest tail relative to its body size.〔 The long-tailed hawk primarily eats squirrels and small birds; it can also hunt chickens in the villages close to the forest. It kills prey by breaking the neck. The mating season occurs in July and August, when the pair build a nest on a high tree. Little is known regarding nesting and breeding the young. ==Etymology== "Uro-" is from the Greek "tail", and "triorchis" meant a kind of hawk thought to have three testicles—for further details see ''Eutriorchis''. "Macro-" is from the Greek for "long",〔 so ''macrourus'' means "long-tailed", as in the English name. 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「Long-tailed hawk」の詳細全文を読む スポンサード リンク
