''Collocalia'' is a genus of swifts, containing some of the smaller species termed "swiftlets". Formerly a catch-all genus for these, a number of its erstwhile members are now normally (though not by all authors) placed in ''Aerodramus''. Remaining in ''Collocalia'' are: * Glossy swiftlet, ''Collocalia esculenta'' * * Grey-rumped swiftlet, ''Collocalia (esculenta) marginata'' * * Christmas swiftlet, ''Collocalia (esculenta) natalis'' * Cave swiftlet, ''Collocalia linchi'' * Bornean swiftlet, ''Collocalia dodgei'' * Pygmy swiftlet, ''Collocalia troglodytes'' An Early Miocene fossil swiftlet from the famous Riversleigh deposits of Australia was described as ''Collocalia buday''.〔Boles (2005)〕 This as well as a right ulna (MNZ S42799) found at the Manuherikia River in Otago, New Zealand and dating from the Early to Middle Miocene (Awamoan to Lillburnian, 19-16 million years ago)〔Worthy ''et al.'' (2007)〕 would probably go into ''Aerodramus'' too. == Footnotes == 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「Collocalia」の詳細全文を読む スポンサード リンク
