13–14 cm. Large swiftlet with proportionally short tail and shallow tail-fork; black upperparts with broad, pale grey rump, pale fringes to lores and over eye; uniformly sooty-brown underparts; thinly feathered tarsi.

Systematics History

Editor's Note: This article requires further editing work to merge existing content into the appropriate Subspecies sections. Please bear with us while this update takes place.

Sometimes considered closely related to A. nuditarsus. Formerly considered conspecific with A. whiteheadi. A specimen from Bougainville I intermediate in size between nominate and race leletensis was provisionally thought to belong within present species, although some plumage details rather different; taxonomic assignation requires further investigation. Two subspecies currently recognized.

Breeding

No information.

Not globally threatened. Currently considered Data Deficient. Restricted-range species: present in New Britain and New Ireland EBA and Solomon Group EBA. Known with certainty from only 2 specimens, collected in 1927 on Guadalcanal and in 1962 on New Ireland. A Bougainville specimen of Jun 1979 (1) requires further investigation. Sightings of unidentified large swiftlets on New Britain in 1980 (2), on New Georgia in Jul 1987 (3) and on New Ireland in Aug 1997, Aug 1999 and Jun 2007 (4) may refer to this species. Observations in Papua New Guinea believed to have been A. orientalis, from Manus in 1989 (5) and Mussau in 1999, clearly refer to Uniform Swiftlet (A. vanikorensis coultasi) which is common on both islands (4). The paucity of records, frustrated by identification difficulties, do not allow an accurate determination of conservation status.
