- Ochthoeca fumicolor
Identification
Upperside to crown is warm brown, with side of head about same color, but the supercilium is strong and pale. Underside is buff to rufous, wings dark with two prominent rufous wing bars. Tail is very dark but outer tail feathers are white. Eye, bill and legs are dark.
Variation
Generally, birds are more bland and buff to the south with stronger rufous tones to the north and north-east.
Subspecies superciliosa differs significantly in being brighter rufous on undersides, supercilium being equally bright rufous and very broad, while it may have only one wing bar. It is also smaller with especially a shorter wing.
Distribution
South America: found in Colombia, Venezuela, Ecuador, Peru and Bolivia.
Taxonomy
Subspecies
Five subspecies are recognized[1]:
- O. f. superciliosa:

- O. f. fumicolor:
- O. f. ferruginea:
- Central and Western Andes of Colombia (Antioquia)
- O. f. brunneifrons:
- O. f. berlepschi:
HBWalive[4] did split this into two species: the first subspecies was called Rufous-browed Chat-tyrant (Ochthoeca superciliosa) while the rest was known as Brown-backed Chat-Tyrant. No other main taxonomic entity has agreed.
