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.
White-winged Nightjar
A small Caprimulgidae nightjar (~50 g) of cerrado grasslands in central South America (Brazil, Bolivia, Paraguay). Males are almost entirely white; females cryptically brown. One of the most distinctive nightjars. Inhabits open grassland with scattered shrubs. Vulnerable from rapid cerrado agricultural conversion.
