Subspecies
Genus often merged into Collocalia. Previously considered conspecific at various times with Himalayan Swiftlet (Aerodramus brevirostris) or Edible-nest Swiftlet (Aerodramus fuciphagus) and has also been associated with Mascarene Swiftlet (Aerodramus francicus) and Seychelles Swiftlet (Aerodramus elaphrus), due mainly to relative geographical proximity. Probably closest to Uniform Swiftlet (Aerodramus vanikorensis) group. Subspecies rogersi of Himalayan Swiftlet (Aerodramus brevirostris) has been tentatively linked with present species on morphological grounds.
