-chestnut crown, nape and sides of the head. The underparts are white with dark streaking, and the upper wings and underwing flight feathers are blackish-brown. The underwing coverts are tawny. The blackish tail has very long outer feathers; these are slightly longer in the male than the female. Juveniles are duller and browner, with less contrast and shorter outer tail feathers. There are five or six subspecies differing in the extent of the underpart streaking.
The lesser striped swallow has heavier and darker underparts striping, a deeper red rump, and a brighter head colour than the larger greater striped swallow.
Behavior
It feeds mainly on flying insects, but has been known to eat small fruits. The flight is erratic, and the call is a nasal ''zeh zeh zeh zeh zeh''.
Breeding
The lesser striped swallow builds a bowl-shaped mud nest with a tubular entrance on the underside of a suitable structure. The nest has a soft lining, and may be reused in later years. The nest may be built in a cave, under a
