Mountain Wren-Babbler Gypsophila crassa

This small mouse-like undergrowth inhabitant can be difficult to spot in the tangled, well-shaded montane forest ravines, gullies, and streams it favors. Listen for its song, a series of high, distinct piping whistles: “hi-hee-hu-huh-hi” or variants thereof. Can be quite inquisitive, allowing close approach; look for a small chunky brown bird with elegant pale eyebrows, an overall brown body with strong streaking, and a contrasting pale throat. Eyebrowed Wren-Babbler overlaps marginally in range but averages lower in elevational preference; it also has white spots on the wings and a different song.
