Brown-rumped Foliage-gleaner Automolus melanopezus

Subtly-patterned foliage-gleaner. Warm dark brown overall, lighter below, with an orange-brown throat patch, and red eye. Found mostly in bamboo forests, as well as occasionally in areas of dense understory within mature rainforest, like vine tangles and in vegetation in upland ravines. Listen for its unique song, consisting of two or three liquid “wheep” notes followed by a chuckling trill accelerating into a rapid “trrrr.”
