About These Birds
Solomons Nightjar
A medium-large Caprimulgidae nightjar (~138 g) endemic to Bougainville and the central Solomon Islands. Dark brown and buff cryptic plumage; relatively large for the genus. Inhabits closed-canopy forest and forest edges. Feeds on insects at night. Vulnerable owing to its very restricted island range and ongoing deforestation.
Papuan Nightjar
A small Caprimulgidae nightjar (~81 g) of lowland savanna, grassland, and forest edges across the southern lowlands of New Guinea. Cryptic buff-and-brown plumage; white-spotted wings visible in flight. Nocturnal aerial insectivore. Commonly heard at night but rarely seen by day. Least Concern.
