The recently described Brown-backed Antwren is considered to form a superspecies with the Foothill Antwren (Epinecrophylla spodionota) and the Stipple-throated Antwren (Epinecrophylla fjeldsaai). Its unusual scientific name honors the Danish ornithologist Jon Fjeldså. This species is highly restricted in range, being confined to southeast Ecuador and extreme north-central Peru, where it is found in lowland evergreen forest on nutrient-poor soils, both on terra firme and, to a lesser extent, in seasonally flooded areas. Our provisional knowledge suggests that it prefers areas with a high density of palms in the understory. Like other Epinecrophylla, the Brown-backed Antwren is a dead-leaf specialist and forages in singles, pairs or as small family groups, but usually withinmixed-species flocks, which are typically led by a species of Thamnomanes antshrike.
