White-winged Potoo (Nyctibius leucopterus)


French: Ibijau à ailes blanches German: Weißflügel-Tagschläfer Spanish: Nictibio aliblanco

Caprimulgus leucopterus


, 1821,

near Conquista, Bahia, Brazil


Two recent studies#R#R found that this species, N. griseus and N. maculosus were closely related. Present species was for some time considered to include N. maculosus as a race, but the two differ in size, plumage, voice, and elevational distribution. Includes two populations: Amazonian form appears to be a new taxon, as yet undescribed; degree of vocal differences in urgent need of clarification, as E Brazilian population evidently small and at risk. Currently treated as monotypic.


Lowlands of Amazonia in E Venezuela#R, N Brazil, the Guianas#R#R and E Peru#R, in distantly scattered localities, probably occurring throughout; also Bahia#R and Espírito Santo#R, in E Brazil.
