Taxonomía

The russet-mantled softtail was originally described in genus Thripophaga. Based on a large molecular phylogenetic study of the suboscines published in 2020 it was moved by worldwide taxonomic systems to genus Cranioleuca. The South American Classification Committee of the American Ornithological Society retains the russet-mantled softtail in Thripophaga but is seeking a formal proposal to move it to Cranioleuca.<p>The russet-mantled softtail is monotypic.

Distribución y hábitat

The russet-mantled softtail is found only in Peru, on the eastern Andes south of the Marañón River between the departments of Amazonas and La Libertad and perhaps further south into Huánuco. It inhabits elfin forest and the edge of humid montane forest. It seems to favor areas with Chusquea bamboo and much moss and bromeliads. In elevation it mostly ranges between 3,050 and 3,400 m (10,000 and 11,200 ft) but occurs locally down to 2,500 m (8,200 ft) and perhaps 1,800 m (5,900 ft).

Comportamiento

The russet-mantled softtail is a year-round resident throughout its range.<p>The russet-mantled softtail feeds on arthropods but details are not known. It forages in pairs or in small groups thought to be families, usually as part of a mixed-species feeding flock. It gleans prey from dead leaf clusters and branches, usually within about 3 m (10 ft) of the ground.<p>The russet-mantled softtail's breeding season appears to be June to September. Nothing else is known about its breeding behavior.<p>The russet-mantled softtail's song is "a short, descending, high-pitched chatter: tchee tchee-tchi-tchi'trrr".
