''Coccycua'' is a small genus of birds in the cuckoo family, Cuculidae. Its three species are found in the tropical Americas. Formerly, they were divided among in ''Coccyzus'' (two species) and ''Piaya'' (one species), or the former were assigned to ''Micrococcyx'' and only the latter to ''Coccycua''. Following the discovery that they form a monophyletic lineage equidistant to both related genera, ''Coccycua'' has been revalidated. ==Species== The species are: * Little cuckoo, ''Coccycua minuta'' * Dwarf cuckoo, ''Coccycua pumila'' * Ash-colored cuckoo, ''Coccycua cinerea'' 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「Coccycua」の詳細全文を読む スポンサード リンク
