The Black-faced Bunting, Emberiza spodocephala , is a passerine bird in the bunting family Emberizidae, a group now separated by most modern authors from the finches, Fringillidae.
It breeds in southern Siberia across to northern China and northern Japan. It is migratory, wintering in northeast India, southern China and northern southeast Asia. It is a very rare wanderer to western Europe.
