Black saw-wing
The black saw-wing (''Psalidoprocne pristoptera''), also known as the blue saw-wing or black rough-winged swallow, is a small passerine bird in the swallow family.
==Distribution and habitat==
The black rough-winged swallow breeds in open wooded habitats, and has a preference for wetter areas, although some races occur in mountain grassland habitat. It breeds across Africa from eastern Nigeria and Ethiopia south to Angola, northern Zimbabwe and northern Mozambique. The subspecies ''P. p. holomelaena'' breeds down south-eastern Africa from southern Mozambique to the Cape in South Africa.
This species is mainly resident, apart from seasonal local or altitudinal movements, but ''P. p. holomelaena'' is migratory, spending the southern winter north of the breeding range. The nominate race ''P. p. pristoptera'' of the mountains of northern Ethiopia moves south after breeding.
