Eastern Striolated-Puffbird Nystalus striolatus Scientific name definitions

The Eastern 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. This species occurs across much of the southern Amazon, with one subspecies in the Rio Madeira-Rio Tapajós interfluvium (just reaching extreme northeastern Bolivia), and a second subspecies restricted to northeastern Brazil, east of the Rio Tapajós.
