Грімпар сірощокий Dendrocincla fuliginosa

Medium-sized woodcreeper; well-named, all plain warm brown with no streaking. Note face pattern: dark mustache line and pale grayish cheek. Bill rather short for a woodcreeper and all dark. Mainly a forest bird, most often seen accompanying a mixed-species flock. Not usually up in the canopy; prefers lower or middle levels.
