The corn bunting (Emberiza calandra) is a passerine bird in the bunting family Emberizidae, a group now separated by most modern authors from the finches, Fringillidae. This is a large bunting with heavily streaked buff-brown plumage. The sexes are similar but the male is slightly larger than the female. Its range extends from Western Europe and North Africa across to northwestern China.
It breeds across southern and central Europe, north Africa and Asia across to Kazakhstan. It is mainly resident, but some birds from colder regions of central Europe and Asia migrate southwards in winter.
The corn bunting is a bird of open country with trees, such as farmland and weedy wasteland. It has declined greatly in north-west Europe due to intensive agricultural practices depriving it of its food supply of weed seeds and insects, the latter especially vital when feeding the young. It has recently become extinct in Wales and Ireland, where it was previously common.
