The lesser striped swallow (Cecropis abyssinica) is a large swallow. It breeds in Sub-Saharan Africa from Sierra Leone and southern Sudan south into eastern South Africa. It is partially migratory with South African birds wintering further north. West African birds leave the north of the breeding range in the dry season.
This is a bird of wooded, mainly lowland habitats. The lesser striped swallow prefers less open habitats, and is replaced in montane grassland by the greater striped swallow, Hirundo cucullata. It is common and often found around human habitation.
The lesser striped swallow is 15–19 cm long. It has dark blue upperparts with a red rump and a rufous-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.

GBIF citizen-science records
It is estimated from how often the Lesser Striped-Swallow is recorded against all the birds logged in Brazzaville (36 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
