A large and long-tailed shrike with dark gray upperparts, white underparts, a black mask, and white in the wing. The white patches in the black wings and tail are especially conspicuous in flight. Found at high elevations, in open habitats with stunted shrubs such as rhododendron. Descends to lower elevations during the winter. Often uses tall and exposed perches. Vocalizations include harsh rasping notes and more musical, liquid ones. Similar to Chinese Gray Shrike, but larger, with a darker gray back and no white eyebrow.
