General Distribution. — The Red-crested Poch.ird breeds 

 in the central and southern parts o£ Europe, from south 

 Germany to Spain and the delta of the Rhone eastwards. 

 It is abundant in the Dimube 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
