The Striolated Puffbird is a brownish puffbird of forest edges and openings. It has a unique combination of barred upperparts and streaked underparts, as well as a heavy, largely pale bill. Its whistled song has a distinctive pattern, two short notes followed by a longer note, then an even longer note on a lower pitch - "whip-whip-wheee, wheeeee". This species often sits motionless on a favored perch in wait for passing insects, and the song, although soft, is often the best clue to a bird's presence. The Striolated Puffbird usually is solitary, but may occasionally associate briefly with a mixed-species canopy flock. The nest is in an underground cavity. This species occurs disjunctly in southern Amazonia from Ecuador east to central Brazil, and also near the mouth of the Amazon in northeastern Brazil.
