White-winged Nightjar

About the White-winged Nightjar

The white-winged nightjar (Eleothreptus candicans) is a species of nightjar in the family Caprimulgidae. It is found in Bolivia, Brazil and Paraguay. The white-winged nightjar, with two other nightjars, was at one time placed in genus Thermochalcis that was later merged into Caprimulgus. Since the early 2010s it has been placed in its current genus Eleothreptus, which it shares with the sickle-winged nightjar (E. anomalus). It is monotypic.

The white-winged nightjar is 19 to 23 cm (7.5 to 9.1 in) long. Adult males weigh 46 to 55 g (1.6 to 1.9 oz) and females 46 to 55 g (1.6 to 1.9 oz). The adult male's upperparts are pale grayish brown with bold blackish spots on the crown and brown streaks, bars, and speckles on most of the rest. Much of the face is brown, with a white supercilium and "moustache". The breast is grayish brown with a chestnut tinge and brown bars and speckles; the rest of the underparts are white. In flight the male shows whitish wings and a mostly white tail. Adult females have buffy underparts and no white in the plumage. Juveniles are browner rather than grayish.
