White-rumped Swift
Apus caffer
The white-rumped swift (Apus caffer) is a species of swift. Although this small bird is superficially similar to a house martin, it is not closely related to that passerine species. The resemblances between the swallows and swifts are due to convergent evolution reflecting similar life styles.

Description
This 14–15.5 cm (5.5–6.1 in) long species has, like some relatives, a short forked tail and long swept-back wings that resemble a crescent or a boomerang. It is entirely dark except for a pale throat patch and a narrow white rump. It is similar to the closely related little swift, but is slimmer, darker and has a more forked tail and a narrower white rump.
Range & habitat
The habitat of this species is dictated by that of its hosts, and is therefore normally man-made structures such as bridges and buildings.
