Western Striolated Puffbird

The eastern striolated puffbird is 19.8 to 21 cm (7.8 to 8.3 in) long and weighs 43 to 47 g (1.5 to 1.7 oz). Its crown is dark brown with rufous spots and bars, blackish toward the rear. Its hindneck has a broad buffy collar. Below that is a blackish band and the rest of the upperparts are dark brown with reddish buff spots and (at the rear) bars. 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.
