A medium-sized wheatear that is variable in plumage, but always has a diagnostic white rump and outer tail feathers in both sexes. The male has both gray and black morphs with white shoulder patches and black wings; gray morphs often have a gray crown. The female is sooty brown. Pairs and small groups perch on promontories in open shrubby hilly areas, stony patches on level ground, and around stone buildings, dropping onto the ground to forage. The similar White-headed Black-Chat resembles male dark-morph Mountain Wheatear, but has a black tail and rump and occupies broadleaf woodland.
