Glossy Swiftlet

The glossy swiftlet is a swift in the family Apodidae. It is shiny black-blue above, including the rump, and sometimes looks black and hooded, with a black chest and a white belly and flanks finely speckled with black at the margins. The wing tips are rounded. The account used here gives its range as Sulawesi east to New Guinea, the Bismarck Archipelago and the Solomon Islands, so its status on Sumatra and the Malay Peninsula (where earlier lists use the name) is not covered (Wikipedia, general species account).
