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.
Least Poorwill
A small Caprimulgidae poorwill (~44 g) of dry scrub and thorn woodland in Hispaniola. Brown-and-buff cryptic plumage. Little studied; biology poorly known for this island endemic. Feeds on insects at night. Near Threatened owing to ongoing habitat degradation and deforestation on Hispaniola. Rarely encountered.
