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 former members are now normally (though not by all authors) placed in Aerodramus.
The genus Collocalia was introduced by the English zoologist George Robert Gray in 1854.[2][3] The name Collocalia combines the classical Greek words kolla meaning "glue" and kalia for "nest".[4]
The genus previously contained fewer species. Seven subspecies of the glossy swiftlet were promoted to species status based on a detailed analysis of the swiftlets in the genus Collocalia published in 2017.[5][6]
