Geographical Distribution. ^ -Sn'&z^ .• Fairly common 

 winter visitor. Only sparingly distributed round the English 

 coasts, especially on the west and south. In Ireland it is equally 

 uncommon, being rare in the south, and of irregular appearance 

 in the west and north. Becomes most numerous in Scotland, 

 both on the east and west, and in the Orkneys and Shetlands, 

 examples having been met with in summer in the latter locality. 

 Throughout the Hebrides it is a well-known and at times even 

 abundant species. Sometimes visits us in unusual numbers, 

 during exceptionally severe weather in the North Sea basin. 

 Foreign : Circumpolar, northern Palsearctic and Nearctic regions ; 

 more southerly in winter. Breeds throughout the Arctic zone 

 above the limits of forest growth, and in a similar climate at high 

 elevations in Scandinavia, in Iceland, and perhaps the Faroes, 

 Its northern range appears to extend as high as land is known, 

 and possibly reaches the North Pole. Winter migrations are not 

 very extended, but at that season it visits the Faroes, the Baltic, 

 the North Sea basin, and much more rarely that of the Mediter- 

 ranean Sea, where it has occurred on the Italian lakes and on 

 the coasts of the Adriatic. Eastwards it visits, during winter, the 

 Caspian Sea, Lake Baikal, North China, and Japan j whilst on 

 the American Continent it is found at that season as far south as 

 the Great Lakes and the Northern United States.
