About These Birds
Lesser Nighthawk
A small Caprimulgidae nighthawk (~50 g) of deserts, semi-arid scrub, and open woodland from the southwestern United States to Peru and Brazil. Brown-and-buff patterned; males have a white throat bar. Low, buoyant flight close to the ground at dusk. Hunts insects aerially. Migratory; 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.
