Distribution in the British Islands. Chiefly a Winter 

 Visitor to our coasts from October onwards, being rarely met 

 with on inland waters. A few Resident pairs have bred 

 during recent years in the north of Scotland, in the Orkneys, 

 and in the Outer Hebrides. 



General Distribution. The Scaup inhabits the greater part 

 of the northern Hemisphere, ranging in summer to 70 N. 

 latitude. Its breeding-range includes Iceland, the Faeroe 

 Islands, and northern Europe and Asia, from Scandinavia 

 to Bering sea; also North America north of about 49 N. 

 latitude from the Pacific to the Atlantic coasts. In winter 

 it is found as far south as the Mediterranean, the lakes 

 of Algeria, and probably Tunisia, but apparently not in 

 Abyssinia ; also on the Black and Caspian seas, rarely in 

 north India, and in China, Japan, and Formosa. In 

 America it visits Texas, New Mexico, southern California,

Distribution in the British Islands, The species was first 

 described by Donovan from a specimen found in Leadenhall 

 Market said to have been taken in Lincolnshire. It seems 

 certain that this bird could not have been imported and must 

 have been a wild example. 



General Distribution. The Ring-necked Duck inhabits 

 North America, breeding from the southern parts of British 

 Columbia to Lake Winnipeg and southwards to northern 

 California, north Dakota, and Lake Michigan. In winter 

 it ranges to Mexico, Central America, and the West Indies.
