Tschudi's nightjar or lesser band-winged nightjar (Quechuavis decussata) is a species of nightjar in the family Caprimulgidae. It is found in Chile and Peru. == Taxonomy == Tschudi's nightjar was formally described as Caprimulgus decussatus in 1844 by the Swiss naturalist Johann Jakob von Tschudi based on a specimen collected in Peru. The specific epithet is Latin meaning "marked with crosses", from decussis meaning "ten" (X in Roman numerals). Tschudi's nightjar has a complicated taxonomic history. It was originally considered a species, then a subspecies of band-winged nightjar (Systellura longirostris). The species was formerly placed in the genus Systellura but a 2014 molecular genetic study of the nightjars by Snorri Sigurðsson and Joel Cracraft found that the Tschudi's nightjar was only distantly related to the other member of the genus, the band-winged nightjar. Tschudi's nightjar was therefore moved to new monotypic genus, Quechuavis, that had been proposed in 2023 by Thiago Costa and coworkers. The genus name is a combination of Quechua, an indigenous people of South America, and the Latin avis meaning bird. The species is monotypic: no subspecies are recognised. == Description == Tschudi's nightjar is 20 to 21 cm (7.9 to 8.3 in) long. Males weigh 28.5…
