The eastern whip-poor-will (Antrostomus vociferus; also called "whip-o-will", "whip o' will", etc.) is a medium-sized (22–27 cm or 8.7–10.6 in) bird within the nightjar family, Caprimulgidae, from North America. The whip-poor-will is commonly heard within its range, but less often seen because of its camouflage. It is named onomatopoeically after its song.
