The slender-tailed nightjar (Caprimulgus clarus) is a species of nightjar in the family Caprimulgidae. It is found in parts of eastern and central Africa, including the Democratic Republic of the Congo, Ethiopia, Kenya, Somalia, South Sudan, Tanzania, and Uganda.
The slender-tailed nightjar is a medium-sized nightjar, measuring approximately 25–28 cm in length. It has cryptically patterned brown, grey, and black plumage, providing effective camouflage against dry ground and leaf litter. The head is relatively large and flattened, with a small bill and a very wide gape adapted for catching insects in flight. The tail is long and tapered, with the central feathers extending beyond the others, giving rise to the species’ common name.
Sexes are similar in appearance, though males may show slightly more prominent pale patches on the wings. No subspecies are currently recognized. The species is distributed across eastern and parts of central Africa. It inhabits dry, open environments including savanna, dry woodland, bushland, open scrub, rocky areas, and sparsely vegetated grassland. It is often associated with semi-arid regions and may occur...

GBIF citizen-science records
It is estimated from how often the Slender-tailed Nightjar is recorded against all the birds logged in Lake Mburo National Park (49 verified sightings from 2019 to 2026), 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.
