Map explanation
This map shows the changes which occurred in the winter relative abundance of the species between 1995-2000 and 2007-2012, but only in the limited selection of tetrads that were surveyed in winter for Birds of Wiltshire (Wiltshire Ornithological Society 2007).

Corn Buntings breed from the Canaries and northwest Africa north through much of southern and western Europe to the southern shores of the Baltic, thence east through south Russia, Asia Minor and parts of the Middle East to Iran, Kazakhstan and northwest China. In Europe they are still common in the south but have declined drastically in countries such as Denmark, Germany - and Great Britain.
In Britain Corn Buntings' numbers fell by 60% between 1970 and 1990 and by a further 24% between 1995 and 2018. Bird Atlas 2007-11 recorded range reductions of 56% in the British breeding season since the 1968-72 Breeding Atlas and of 27% in the winter since the 1981-84 Winter Atlas. Losses in southern Scotland, northern England and the English midlands have reduced the remaining populations largely to discrete areas, in particular of chalk grasslands.
In the 19th century Corn Buntings were common and widespread in Wiltshire and they have continued to prosper on the county's chalk uplands whilst declining elsewhere. Birds of Wiltshire recorded them in 295 tetrads, with breeding in 160. WTA2 recorded them in 285 tetrads, with breeding in 141.
