The greater striped swallow is long. It has dark blue upperparts with a pale orange rump and a chestnut crown, nape and sides of the head. The underparts and underwing coverts are creamy white with dark streaking, and the upper wings and underwing flight feathers are blackish-brown. 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. The flight is slow and buoyant, and the call is a twittering chissick.
