摘要

The ecology of the White-winged Nightjar (Eleothreptus candicans) is poorly known. Only three breeding populations (one from Brazil and two from Paraguay) are known, and populations are decreasing due to continuing destruction of cerrado habitat. On 14 September 2003, we took several photos of an unidentified nightjar in Beni Biosphere Reserve, Departmento Beni, Bolivia. The bird was later determined to be an adult male White-winged Nightjar. Interestingly, the only previous record for Bolivia was a male collected in 1987 at the same locality and time of year. Because the White-winged Nightjar is non-migratory and secretive, we hypothesize that there may be a sustainable population of White-winged Nightjars in Bolivia, and the paucity of sightings may be due to the species' low detectability.
