As with all swifts, the little swift forms monogamous breeding pairs (5), with each pair laying one to three eggs, which are incubated for 22 to 24 days (2). The breeding pair is capable of ‘double-clutching’, which means that if the first clutch of eggs is lost they will produce a second to replace it (2). The nest of the little swift is robust and messy-looking outside, but smooth and neat inside. It is hemispherical in shape and built from grass, small twigs, down and feathers, which are glued together with saliva (2). Nests are built in groups of up to 30, and two to three females may lay their eggs in a shared nest (2). The breeding season of this bird depends on the location and the weather; for example, in Senegal and Gambia it breeds from October to July and avoids the rainy season, whereas the little swift breeds all year round in West African rainforest (2).
The swift family are renowned for feeding whilst flying, taking and eating airborne insects such as flying ants, bees, wasps, and beetles on the wing (4). Swifts also drink whilst flying by swooping low and scooping up water into their beaks (2).
