RANGE Breeding range very patchy and discontinuous in most of Europe. Scattered pockets in Iceland, the British Isles and in most Continental countries from western France to Russia where becomes more widespread and range is more continuous. Absent from Scandinavia, except a small part of east Sweden, and from much of the Mediterranean region but small numbers breed in Morocco and Iberia, Italy, the Balkans and Turkey. Some populations, as in Britain, are descended from introduced stock. Recently bred for the first time in the Channel Islands. Breeds widely across temperate Asia to northern China and may breed on Hokkaido. In North America breeds in central and southern Alaska, western and south-central Canada and the north-central and western USA south to California and Texas. | RANGE Breeding range very patchy and discontinuous in most of Europe.
