Habitat
Breeds on cliffs and feeds aerially over a wide variety of vegetation types, favouring open areas, especially high-altitude grasslands.
Behaviour
Diet
Often feed alone, but sometimes in flocks. Feeds on insects caught in flight; sometimes feeds at night. Attracted to emergences of termite alates and to fires.
Breeding
Breeds in colonies on cliffs (sometimes trees in eastern Africa). Shallow nest built in crevice using feathers, grass and plant down collected aerially. One to two white eggs are laid (September to February in southern Africa).
Vocalisation
The call is a screaming 'shree', higher-pitched than the call of the Common Swift, and repeated frequently in aerial displays.
