Rufous-fronted Antthrush Formicarius rufifrons

Range-restricted antthrush of river’s-edge habitats and bamboo. Grayish brown, with an orange forehead. Found in successional forest with dense understory, including areas with bamboo or dense heliconia thickets. Listen for its song, a long, rising-falling series of musical whistles. Voice is similar to the slower song of Buff-throated Woodcreeper, but ascends faster in the middle of the song.
