Hebrides and the Island of Jura. On the East Coast it breeds as far north as Inverness, and on migration is found regularly in the Orkney, Shetland and Faroe Islands. To Ireland it is a local summer visitor, rare in many counties, but breeding regularly in Dublin, Wicklow, Kildare, and Queen's County.
Its occurrence in the Channel Islands except Guernsey seems doubtful.
In the Cape Verd Islands, Canary Islands, Madeira, Azores, and the countries bordering the Western Mediterranean it is a common resident species.
Over Central Europe and Southern Scandinavia it is generally distributed and common as a breeding species, and we find it occurring regularly, though in gradually lessening numbers, as far as 66° N. Lat. Records have been obtained as far north as the Lyngen Fiord. Proceeding eastward from here we find it somewhat scarce in Finland, occurring principally in the vicinity of Helsingfors, Uskela, Kuopio, and as far north as Uleaborg. In the Province of Olonetz it has been recorded near Petrozavodsk, Witegra and Kargopol, and on the River Dwina as far as 62° N. Lat. It also visits the Province of Viatka, and appears to be much rarer on the eastern slopes of the Ural Mountains than on the western.
In Southern Europe it is found throughout Italy and the Islands of Corsica and Sardinia, but in Greece it is rare as a breeding species, though common during the winter, and occurs on migration in Crete. In Montenegro and Turkey the bird is not plentiful as a breeding species, but passes through the latter country on migration. To the Southwestern Provinces of Russia and throughout the Caucasus it is a frequent visitor, but it is doubtful whether it breeds in the Crimea, although it occurs on migration. In Trans-Caucasia it is by no means uncommon, being found from Abkhasia in the west to Lenkoran in the east, and on migration it visits the Caspian Steppes. In parts of Asia Minor and Persia, as far east as Teheran, it appears to be a resident species.
