Big-headed flycatcher of humid rainforest midstory. Rich red-brown with a slightly grayer head and pale eye. Perches with upright posture and appears rather stocky, with a short tail, large head, and heavy bill. Pale eye and fairly dark plumage help distinguish it from other attilas, as does voice. Listen for a rising series of whistles, usually finished with a lower note: “weer, weer, weer, weer, woo”; sounds melancholy, without the upbeat, double-syllable note phrasing of Bright-rumped Attila.
