Can be easily separate from similar looking Edible-nest Swiftlet and Black-nest Swiftlet by the whitish belly/vent and all black upperparts without any pale rump-band.

Where overlapping with Bornean Swiftlet, Plume-toed Swiftlet is 10-20% larger but this is probably not useful in the field. Color of the gloss is not helpful, though overall lack of gloss in Bornean might be. Plume-toed Swiftlet has a capped appearance with a dark, glossy cap that contrasts with a less glossy, brown rest of face. This effect is less strong in Bornean Swiftlet. It may also be worth-while to check recordings before going into the field.

Distribution

From Andamans, Nicobars, and Malay Peninsula south through Sumatra and offshore islands like Nias, Batu Islands and Mentawi Islands.

Taxonomy

Formerly included in Glossy Swiftlet.
