Marquesan swiftlet

The Marquesan swiftlet (Aerodramus ocistus) is a species of swift in the family Apodidae that is endemic to French Polynesia, where its natural habitat is subtropical or tropical moist lowland forest. Its status as a species is not settled between authorities. The IOC World Bird List, in version 15.1, treats it as a full species, while the IUCN and BirdLife International treat it as a subspecies, Aerodramus leucophaeus ocistus, of the Polynesian swiftlet. A reader who finds it listed under either name is therefore looking at the same bird, classified by different taxonomic authorities.
