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.

With luck
About 10% of wildlife watchers report a White-winged Nightjar sighting in Emas National Park on a given day, based on 44 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 109th most-seen of the 187 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
September
In that month about 40% of wildlife watchers report a White-winged Nightjar in Emas National Park on a given day, against under 5% in October, the lowest month. That is one of Emas National Park's driest months, with about 35 mm of rain against 190 mm in January. April and December–February have too few records to rate.
Between 6 and 9 pm
Across all the parks we cover, that three-hour window holds the most White-winged Nightjar sightings with a recorded time, and about 9 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Only Emas National Park, in our data
Emas National Park is the only park on Wallace's Line with enough records to rate White-winged Nightjar sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the White-winged Nightjar is recorded against all the birds logged in Emas National Park (44 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
