White-winged Potoo
Nyctibius leucopterus

Description
The 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.
Range & habitat
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. There it inhabits the canopy of mature terra firme rainforest, including forest on white-sand soils. In the early 2000s researchers made several sightings along the Amazon on poor but non-sandy soils between areas of white-sand forest. The eastern form has a much smaller range in Brazil's Bahia and Espírito Santo states. It is not well known but is assumed to inhabit the canopy of the Atlantic Forest.
