The blackish nightjar, with the scientific name Nyctipolus nigrescens (Cabanis, 1849), measures 19.5 to 21.5 cm (7.7 to 8.5 in) in length and weighs 32 to 39 g (1.1 to 1.4 oz). Its upperparts are blackish brown, marked with tawny, grayish white, and cinnamon spots. Its tail is dark brown, with indistinct lighter bars and mottling; males have a white tip on the tail. The underparts down to the belly are dark brown with paler barring, while the belly and flanks are buffy with darker barring. A small white patch is present on either side of the throat. A small white band is visible on the wing when the bird is in flight. The blackish nightjar is distributed east of the Andes in Peru, Ecuador, and southern Colombia, and extends across southern Colombia through southern Venezuela and the Guianas into northeastern and north-central Brazil. It inhabits lowland evergreen forest, and is mostly found on or near open rock outcroppings, or on sand and gravel bars alongside small rivers. Its elevational range extends from sea level in Brazil, up to 900 m (3,000 ft) in Bolivia, 800 m (2,600 ft) in Colombia, 1,200 m (3,900 ft) in Ecuador, and 1,100 m (3,600 ft) in Venezuela.
