The Chuck-will's-widow (Antrostomus carolinensis), is a species of nightjar in the Caprimulgidae family. It is found in the southeastern United States near swamps, rocky uplands, and pine woods. It migrates to the West Indies, Central America, and northwestern South America. This bird is generally confused with the better-known whip-poor-will (Antrostomus vociferus), due to their similar calls and unusual names. Though rather closely related, they are two distinct species.
