Chuck-will's-widow
（重定向自Caprimulgus carolinensis）
The chuck-will's-widow (Antrostomus carolinensis) is a nocturnal bird of the nightjar family Caprimulgidae. 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 whippoorwill (Antrostomus vociferus), due to their similar calls and unusual names. Though rather closely related, they are two distinct species.
