The Himalayan swiftlet (Aerodramus brevirostris), is a species of small swift in the Apodidae family. It is a common colonial breeder in the Himalayas and Southeast Asia. Some populations are migratory. This swiftlet was formerly placed in the genus Collocalia. Two of its five subspecies are frequently given full species status, Aerodramus brevirostris rogersi as the Indochinese swiftlet (Aerodramus rogersi), and the isolated Javan form Aerodramus brevirostris vulcanorum as the volcano swiftlet (Aerodramus vulcanorum).
