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. 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 face is olive-tinged gray with black lores. Their chin and throat are white, their breast light yellowish olive-brown, their belly a whiter olive-brown, and their flanks, crissum, and underwing coverts dark gray-tinged olive-brown. The white-shouldered fire-eye is found in eastern Brazil from eastern Bahia and southwestern Minas Gerais south to Mato Grosso do Sul and extreme northern Rio Grande do Sul, in eastern Paraguay from Canindeyú to Itapúa, and in extreme northeastern Argentina's Misiones Province. It inhabits dense understorey vegetation in lowland evergreen forest. It mostly occurs at the edges of primary forest, in mature secondary forest, and in clearings such as those caused by fallen trees. It also occurs in selectively logged forest and in plantations. It favors areas with dense thickets, vine tangles, and large stands of bamboo. It shuns sunlit areas such as open woodland with little undergrowth. In elevation it ranges from near sea level to about 1,300 m (4,300 ft).
