Yellow-rumped Antwren Euchrepomis sharpei Scientific name definitions

Yellow-rumped Antwren is a small, slender-built, and highly arboreal antwren found in middle- to lower elevational cloud forest habitat in southeastern Peru and western Bolivia. The species appear to be restricted to undisturbed forest habitat within a narrow elevational and geographic range, having been found at only a small number of locations. Males and females are dimorphic, and the species is almost always seen in pairs foraging high in the canopy of taller trees, with large, species-rich mixed flocks. The speed at which they forage (often acrobatically) and their preference for dense, canopy foliage cover as foraging substrates makes it difficult to make detailed observations. Probably an intrinsically low density species, Yellow-rumped Antwren is currently listed as ‘Endangered’ due to widespread clearance of forest habitat within its narrow range. Quantitative abundance and habitat surveys are among the conservation measures urgently needed.
