Description

This mid-sized laughingthrush is found along the Himalayas and can be identified by the combination of the black cap and band on the brown tail. The underparts are greyish while the upperparts have scale like feather patterning. A distinctive pale loreal patch of buff colour and a broad dark moustachial stripe which borders the rufous chin and ear coverts are identifying features. There is however considerable geographic variation in plumage. The western population (''occidentalis'' of western and central Himalayas) being greyer and paler making the dark patterns stand out in greater contrast. The eastern populations ''assamensis'' have a paler throat and the markings on the throat are much less marked. The populations in Meghalaya (''rufitincta'') has an orange wash on the underside from the throat to the belly. It is found in
