Little Swift

Very common resident. Large white rump, which extends over the sides of the body, and square tail distinguish this species from all but the [Mottled Spinetail]. Differs from this species in clear white throat. Wings less pointed than those of other swifts. Often flies with wings angled steeply upwards, tail fanned. A noisy species, flocks making a high-pitched screaming in flight. During the day, feeds in flocks well away from its roost and regularly mixes with other swifts or swallows. Very common in towns, where it roosts and breeds under eaves and bridges, and on silos and tall buildings.
