Identification

14-15 cm (5½-6 in)
Almost uniform rufous with a paler belly not often visible in the field. Bill and legs are dark grey, iris is brown.

Similar species

Usually occurs at lower elevation than nearby populations of the former Rufous Antpitta which has an eye ring and are less reddish.

Distribution

South America: found on the east slope of the Andes of northern Peru (Amazonas south of the Marañón River, south to Huánuco, north of Huallaga River).

Taxonomy

This is a monotypic species[1].

This species and 15 others were previously included in a complex of Rufous Antpitta/Chestnut Antpitta. Those specifically split from Chestnut Antpitta include Oxapampa Antpitta and Ayacucho Antpitta.

Habitat

Dense undergrowth including bamboo in humid montane forests and second growth at 1700–3000 m asl.

Behaviour

Terrestrial, usually within a meter of the ground.

Vocalizations

The song consists of a rapid series of chiming notes that increase in speed through the song. In spite of a good number of recordings being available, no short song has been recorded for this species, contra the other members of the complex of Rufous Antpitta/Chestnut Antpitta.
