Buteoninae is a bird of prey subfamily which consists of medium to large broad-winged species. They have large powerful hooked beaks for tearing flesh from their prey, strong legs and powerful talons. They also have extremely keen eyesight to enable them to spot potential prey from a distance. This subfamily contains the buzzards (buteoine hawks), true eagles and sea eagles. ==Systematics== SUBFAMILY BUTEONINAE *Genus ''Geranoaetus'' – black-chested buzzard-eagle *Genus ''Buteo'' – buteonine hawks (North America) or buzzards (Europe): nearly 30 species (probably paraphyletic, might include ''Leucopternis'' in part and ''Parabuteo'') *Genus ''Parabuteo'' – Harris's hawk *Genus ''Buteogallus'' – crab hawks: 5 species (probably paraphyletic, might include ''Leucopternis'' in part and ''Harpyhaliaetus'') *Genus ''Busarellus'' – black-collared hawk *Genus ''Cryptoleucopteryx'' – plumbeous hawk * Genus ''Pseudastur'' – white hawks: 3 species * Genus ''Morphnarchus'' – barred hawk *Genus ''Leucopternis'' – grey hawks (probably polyphyletic) * * Black-faced hawk, ''Leucopternis melanops'' * * White-browed hawk, ''Leucopternis kuhli'' * * Semiplumbeous hawk, ''Leucopternis semiplumbeus'' *Genus ''Kaupifalco'' – lizard buzzard *Genus ''Butastur'' * * Grasshopper buzzard, ''Butastur rufipennis'' * * White-eyed buzzard, ''Butastur teesa'' * * Rufous-winged buzzard, ''Butastur liventer'' * * Grey-faced buzzard, ''Butastur indicus'' *Genus ''Morphnus'' – crested eagle *Genus ''Harpia'' – harpy eagle *Genus ''Pithecophaga'' – Philippine eagle *Genus ''Harpyopsis'' – Papuan eagle *Genus ''Oroaetus'' * * Black-and-chestnut eagle, ''Oroaetus isidori'' *Genus ''Spizastur'' * * Black-and-white hawk-eagle, ''Spizastur melanoleucus'' *Genus ''Spizaetus'' crested hawk-eagles: c.4 species *Genus ''Nisaetus'' – c.9 species *Genus ''Lophaetus'' – long-crested eagle (possibly junior synonym of ''Ictinaetus'') *Genus ''Stephanoaetus'' – crowned eagle *Genus ''Polemaetus'' – martial eagle *Genus ''"Hieraaetus"'' – hawk-eagles: 3 species; Genus name unavailable or belongs in ''Aquila'' *Genus ''Lophotriorchis'' – rufous-bellied hawk-eagle *Genus ''Aquila'' – true eagles: 9 species; *Genus ''Clanga'' – spotted eagles 3 species; *Genus ''Ictinaetus'' – black eagle *Genus ''Haliaeetus'' – sea eagles and brown fish eagles: 8 species *Genus ''Ichthyophaga'' – grey fish eagles: 2 species *Genus ''Harpagornis'' – might belong into ''Aquila'' * * Haast's eagle, ''Harpagornis moorei'' (extinct) 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「Buteoninae」の詳細全文を読む スポンサード リンク
