Geographic Variation

Two subspecies:

castaneiceps Sclater and Salvin 1868. Type locality Rio Napo, eastern Ecuador

Occurs from eastern Ecuador south to Bolivia. See Detailed Description.

cocciniepes Olson 1973; type locality Puerto Valencia, 15 km southeast of Florencia, Caquetá, Colombia

Occurs from southeastern Colombia south to northeastern Peru. Distribution with respect to castaneiceps not entirely known, but in Peru the two taxa replace one another across the Río Napo (Schulenberg et al. 2007), and the same pattern is suspected in Ecuador (Ridgely and Greenfield 2001a).

Primarily differs in the color of the tarsi, which are red or pinkish (rather than olive or brown, as in castaneiceps). Also reported (Olson 1973) to differ by having greener (less brown) upperparts, and paler, more tawny tones to the portions of the underparts that are rufous. Ridgely and Greenfield (2001a), however, suggest that the plumage characters may not be valid.
