About These Birds
Antillean Nighthawk
A small Caprimulgidae nighthawk (~56 g) of open scrub, savannas, and coastal habitats in the Caribbean from Cuba and Hispaniola to Puerto Rico and the Virgin Islands. Very similar to the Common Nighthawk but separated by voice. Migratory; winters in South America. Aerial insectivore; Least Concern.
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.
