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.
