Identification

Field Identification

A small, strikingly marked shrike-babbler which has several similar-looking but entirely allopatric congeners. Females are predominantly yellow and gray, and are browner in comparison to males (but still quite distinctive in range), with cinnamon and gray wingbars, a pale cinnamon tinge on the forehead, and paler whitish underparts. Males have a broad chestnut-brown forehead, throat and upper breast, a broad silver-gray eyestripe and eye-ring, contrasting black and white wingbars, and otherwise very yellow underparts and olive-green upperparts.

Similar Species Summary

Distinctive in range.

Similar Species

The formerly conspecific Clicking Shrike-Babbler (Pteruthius intermedius) is very similar in plumage but more distinctive with respect to its vocalizations; P. i. intermedius apparently differs only in ‘the hues of coloration’ and its less pronounced sexual dimorphism, with females having a more vivid yellow coloration below (1). Black-eared Shrike-Babbler (Pteruthius melanotis) differs in having a black ear-covert patch (in both sexes) and a more male-like female plumage.
