starts withThe white-winged potoo has two forms that differ significantly in size but are almost identical otherwise. The species as a whole is 24 to 29 cm (9.4 to 11.4 in) long. The Amazonian form weighs 77 to 85 g (2.7 to 3.0 oz); it is much smaller than the eastern one though the latter's weight has not been documented. Both forms are dark brown above and lighter brown below, and both parts have darker speckles. The large white patch on the secondary wing coverts give the species its name.
The Amazonian form of white-winged potoo is known from scattered sites in the Amazon basin of Eastern Venezuela, eastern Peru, the Guianas, and northern Brazil, though it probably occurs throughout the region. The eastern form has a much smaller range in Brazil's Bahia and Espírito Santo states. In Amazonia it inhabits the canopy of mature terra firme rainforest. The eastern form is not well known but is assumed to inhabit the canopy of the Atlantic Forest.
The white-winged potoo is nocturnal. It captures its insect prey by sallying from an exposed perch.
The white-winged potoo's breeding phenology is unknown. It is assumed to lay one egg on a branch high in the canopy in a manner similar to that of other potoos.
The IUCN has assessed the white-winged potoo as being of Least Concern, though its population is unknown and thought to be decreasing. In Amazonia, "the biggest threat comes from continued destruction of pristine forest."
