Taxonomy and systematics
The Lesser Antillean swift, pale-rumped swift (C. egregia), grey-rumped swift (C. cinereiventris), and band-rumped swift (C. spinicaudus) were at one time placed in genus Acanthylis.[2] The Lesser Antillean swift is monotypic.[3]
Description
The Lesser Antillean swift is 10.5 to 11 cm (4.1 to 4.3 in) long and weighs an average of 12.7 g (0.45 oz). It has a protruding head, a short square tail, and wings that bulge in the middle and somewhat hook at the end. The sexes are alike. Adults have black-brown upperparts with a narrow gray band on the rump. Their underparts are brown with a paler throat. Juveniles have white tips on some wing feathers.[2]

There is also an undocumented sight record further north on Nevis. It principally inhabits tropical lowland evergreen forest but is also found over secondary forest and open areas including drier ones.[2]
