The rufous-crowned antpitta or rufous-crowned pittasoma (Pittasoma rufopileatum) is a species of bird in the gnateater family, Conopophagidae. It is found in Colombia and Ecuador.

Taxonomy and systematics

The position of the two species in genus Pittasoma in linear format is unsettled. The International Ornithological Committee (IOC) and the Clements taxonomy place them differently within the gnateater family.
 Three subspecies of rufous-crowned antpitta are recognized, the nominate Pittasoma rufopileatum rufopileatum, P. r. rosenbergi, and P. r. harterti. It has been suggested that harterti should be merged into the nominate subspecies.

Description

The rufous-crowned antpitta is  long. One male specimen weighed  and a female . In body shape it resembles the "true" antpittas of family Grallariidae. The nominate male's crown is bright rufous with a bold black band below it. Its face is yellowish. The upper parts of the body are olive brown with a scaly appearance. The wings are brownish and have small white spots. The throat and crissum (the area around the cloaca) are buffy and the flanks a yellowish buff. Wavy black barring covers most of the under parts. The nominate female is similar, but the crown is not as bright, the black band is smaller, and the face is more rufous. The underside is creamier and the black barring is less prominent.

P. r. rosenbergi is similar to the nominate but it is smaller and its colors are duller. Both sexes' heads are rufuous rather than just the crown, and the underside does not have the black bars. P. r. harterti is intermediate between the nominate and rosenbergi. The entire face is rufous and it has barring on the underside.

Distribution and habitat

The rufous-crowned antpitta is found on the Pacific slope of Colombia and Ecuador. P. r. rosenbergi is the furthest north; it occurs only in Chocó Department of Colombia. P. r. harterti occurs in western Nariño Department, also in Colombia. The nominate occurs in Ecuador's Esmeraldas and Pichincha Provinces. The rufous-crowned antpitta inhabits humid forests in the lowlands and foothills of the Chocó biogeographic region up to  elevation. No details of its preferences within that biome have been documented.

Behavior
