The tail is narrow and blackish brown with thin rufous bars. The face has a white spot in front of the eye; the rest of the face is buffy with fine dusky streaks. Voice: The western striolated puffbird's song is "a soft, sad whistle, whip, whi-wheeu, wheeeeeuu, with distinctive cadence, first rising, then falling after short pause." The song is typically given shortly after dawn or just before dusk. Often the male sings first and is quickly followed by the female at a slightly lower pitch.
