Grey-winged Cotinga

The grey-winged cotinga (Lipaugus conditus) is a Vulnerable species of bird in the family Cotingidae. It is endemic to Brazil. == Taxonomy and systematics == The grey-winged cotinga was originally described as Tijuca condita. The type specimen had been collected in 1942 and classified as a female black-and-gold cotinga (then T. atra, now Lipaugus ater). Analyses of feather proteins in the specimen and black-and-gold cotingas proved that it was a separate species. The species' specific epithet conditus is from Latin conditus, stored away or hidden, in reference to the specimen's "hiding" under the wrong name for 30 years. The type specimen remains the only one of the species. Not long after the species was described there were suggestions that genus Tijuca was a sister genus to Lipaugus. A molecular phylogenetic study published in 2014 found that Tijuca was embedded within Lipaugus so taxonomic systems subsumed Tijuca into Lipaugus. The grey-winged cotinga is monotypic. == Description == The grey-winged cotinga is about 24 cm (9.4 in) long. The sexes are mildly sexually dimorphic. Adult males have an olive-green crown and a dull grayish face. Their upperparts are mostly olive-green with a yellower rump. Their wings and tail are a darker olive-green…
