General Distribution. The Red-crested Pochard breeds 

 in the central and southern parts of Europe, from south 

 Germany to Spain and the delta of the Rhone eastwards. 

 It is abundant in the Danube valley and parts of south 

 Russia; also in Asia from north Persia to eastern Turkestan. 

 Southwards it nests in north Africa, but appears to be rare 

 in Egypt. In winter it inhabits the basins of the Medi- 

 terranean, Black, and Caspian seas, ranging to India and 

 occasionally to western China. It is an accidental visitor to 

 northern and western Europe, and has occurred once in the 

 eastern United States.

 met with principally in the eastern and southern counties of 

 Kngland, though a few have been obtained in the west, and

General Distribution. The White-eyed Pochard breeds 

 in central and southern Europe, western Asia as far east as 

 Kashmir, and in north Africa. Its reported occurrence in 

 the Obi valley requires confirmation. It winters in Africa 

 north of 14 N. latitude, and ranges thence to India as far 

 east as the longitude of Calcutta and southwards to about 

 14 N. latitude.
