Its natural habitat is subtropical or tropical moist lowland forests. It was previously considered a subspecies of the glossy swiftlet.
The plume-toed swiftlet was described by the English ornithologist Robert Cecil Beavan in 1867 and given current binomial name Collocalia affinis. The type locality is Port Blair in the Andaman Islands.[1][2] The specific epithet affinis is Latin for "related" or "applied".[3] The plume-toed swiftlet was previously treated as a subspecies of the glossy swiftlet but was promoted to species status based on the results of a detailed analysis of the swiftlets in the genus Collocalia published in 2017.[4][5]
There are five subspecies:[5]
The plume-toed swiftlet is 9–10 cm (3.5–3.9 in) in length with a square tail.[6] The back and upper surface of the wings are uniformly dark greenish-blue with a moderate gloss. The throat and upper breast are dark grey merging into large greyish chevrons over the lower breast and flanks, usually becoming white over the belly. There is a tuft of small feathers on the hallux, the rear facing toe. This species lacks a pale contrasting rump and has no white spots on the inner webs of the tail feathers.[4]
