Drab Swiftlet
Collocalia neglecta
A very small, square-tailed dark swift with a dirty white breast, belly, and base of the undertail. An aerial species, usually seen in flocks in flight over a variety of habitats, including forest. In its limited range within the eastern Lesser Sundas, it only overlaps with one other similar species, White-nest Swiftlet. Drab Swiftlet is smaller, lacking an obvious tail notch, and has white underparts.
识别特征
The drab swiftlet is 9–10 cm (3.5–3.9 in) in length with a square tail. It has a satin grayish-blue back with slightly glossy crown and tail. The throat and the upper breast is a mid-gray with a lighter margin to the feathers. The lower breast, flanks and belly are white but the rump is dark. There are dull white spots on the inner webs of the tail feathers. Most birds have a tuft of feathers on the hallux, the rear facing toe. Subspecies perneglecta is darker and has more gloss on the feathers.
分类信息
The drab swiftlet was described by the English zoologist George Robert Gray in 1866 under the binomial name Collocalia neglecta. The type locality is the island of Timor in the Lesser Sunda Islands. The specific epithet neglecta is from the Latin neglectus meaning "ignored", "overlooked" or "neglected". It was formerly treated as a subspecies of the glossy swiftlet but was raised to species status based on a detailed analysis of the swiftlets in the genus Collocalia published in 2017.<p>There are two subspecies:
