The Russet-mantled Softtail is a distinctly uncommon and infrequently recorded rufous-brown furnariid that is endemic to the Andes of northern Peru. It currently is considered Vulnerable to extinction. Most of the upperparts and the breast of this softtail are rufous, becoming paler over the belly and rump, with an indistinctly grayish buff crown and chin. Very little is known concerning the species’ ecology and behavior, but it inhabits montane and elfin forest, at 1800-3350 m, and it apparently can persist in relatively small forest fragments. The Russet-mantled Softtail is most commonly observed in pairs, which frequently accompany mixed-species flocks in the understorey, but sometimes range up to the canopy of lower stature trees.
