Collocalia esculenta |
Collocalia is a genus of swifts, contaning 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
- Cave Swiftlet, Collocalia linchi
- Pygmy Swiftlet, Collocalia troglodytes
An Early Miocene fossil swiftlet from the famous Riversleigh deposits of Australia was described as Collocalia buday[1]. 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)[2] would probably go into Aerodramus too.
