White-shouldered Fire-eye

The white-shouldered fire-eye (Pyriglena leucoptera) is a species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is found in Argentina, Brazil, and Paraguay. == Taxonomy and systematics == The white-shouldered fire-eye was described by the French ornithologist Louis Pierre Vieillot in 1818 and given the binomial name Turdus leucopterus. The specific name is from the Ancient Greek leukopteros meaning "white-winged". The current genus Pyriglena was introduced by the German ornithologist Jean Cabanis in 1847. The species at times has been treated as conspecific with the fringe-backed fire-eye (P. atra) and what was at the time the white-backed fire-eye (P. leuconata); the latter has since been split into several species. The white-shouldered fire-eye is monotypic. == Description == The white-shouldered fire-eye is 16 to 18 cm (6.3 to 7.1 in) long and weighs 25 to 34 g (0.88 to 1.2 oz). Adults of both sexes have bright red irises. Males are mostly glossy black. They have a white patch between their scapulars, white lesser wing coverts, white-tipped median and greater wing coverts, and blackish gray underwing coverts. Females have yellowish brown to chestnut crown, upperparts, and wings with no interscapular patch. Their tail is brownish black. Their…
