About These Birds
Rufous Nightjar
A medium Caprimulgidae nightjar (~87 g) of tropical dry forest, scrubby woodland, and clearings in Central and South America. Rich rufous-brown plumage makes it one of the more distinctively coloured nightjars. Calls with a rolling 'chuck-will's-widow'-like phrase in Spanish-speaking regions. Feeds on large insects. Least Concern.

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.
