About Myrmeciza hyperythra (P.L.Sclater, 1855)
The plumbeous antbird, Myrmeciza hyperythra (P.L.Sclater, 1855), measures 17 to 18 cm (6.7 to 7.1 in) in length and weighs 38 to 44 g (1.3 to 1.6 oz). Males are mostly dark slaty gray, with blackish gray wings and tail that have white spots at the tips of the wing coverts, and a large patch of bare light blue skin surrounding the eye. Females share the male's dark slaty gray coloration on the upperparts, wings, and tail, but have bright rufous underparts with a brown tinge on the flanks and crissum. This species is distributed across the western Amazon Basin. Its range extends south from Caquetá Department in southern Colombia, and Sucumbíos and Orellana provinces in northeastern Ecuador, through eastern Peru into northwestern Bolivia, and east into Brazil to the Purus River basin. It lives on the floor and in the understorey of evergreen forest. It prefers the interior of várzea where tree falls have created openings, but can also be found in transitional forest, along small watercourses, and near oxbow lakes. In terms of elevation, it reaches up to 500 m (1,600 ft) in Colombia and up to 300 m (1,000 ft) in Ecuador. In Peru it mostly occurs below 500 m (1,600 ft), though it can be found locally as high as 800 m (2,600 ft).
