''Circaetus'', the snake eagles, is a genus of medium-sized eagles in the bird of prey family Accipitridae. These are mainly resident African species, but the migratory short-toed snake eagle breeds from the Mediterranean basin into Russia, the Middle East and India, and winters in sub-Saharan Africa and east to Indonesia. Snake eagles are found in open habitats like cultivated plains arid savanna, but require trees in which to build a stick nest. The single egg is incubated mainly or entirely by the female. ''Circaetus'' eagles have a rounded head and broad wings. They prey on reptiles, mainly snakes, but also take lizards and occasionally small mammals. ==Species in taxonomic order== * Short-toed snake eagle, ''Circaetus gallicus'' * Black-chested snake eagle, ''Circaetus pectoralis'' - sometimes included in ''C. gallicus'' * Beaudouin's snake eagle, ''Circaetus beaudouini'' - sometimes included in ''C. gallicus'' * Brown snake eagle, ''Circaetus cinereus'' * Southern banded snake eagle or fasciated snake eagle, ''Circaetus fasciolatus'' * Western banded snake eagle, ''Circaetus cinerascens'' 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「Circaetus」の詳細全文を読む スポンサード リンク
