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 Island Swiftlet, Collocalia (esculenta) natalis
• 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.
