An authoritative online life history for the Critically Endangered Puerto Rican Nightjar Caprimulgus noctitherus has been published on Neotropical Birds Online. The species account deals with identification, distribution, life history, conservation and future research recommendations and provides an essential resource for the conservation of this species.
The Puerto Rican Nightjar is endemic to the coastal and lower montane forests of southern and south-western Puerto Rico. Recent research suggests that it is more common than was thought but the species remains at risk from anthropogenic habitat loss or degradation. Puerto Rican Nightjars are more abundant in the upland forest in and around the Guánica Biosphere Reserve. However, nightjars range as far as Cabo Rojo in the extreme south-western tip of the island, to the municipality of Guayama in south-eastern Puerto Rico. They exhibit a preference for semi-deciduous and evergreen forest types.
