The Red-necked Grebe is a regular winter visitor to the British Islands, 

 most numerous in severe seasons. It occurs sparingly on almost the entire 

 eastern coast-line of Scotland and England, from the Orkneys south arid 

 west to Kentj Cornwall, and the Channel Islands ; but in the Shetlands it 

 is rare. It is less frequent on the west coast of Scotland and England ; 

 and Thompson only records four examples as having been killed in 

 Ireland. 



The Red-necked Grebe is almost a circura polar bird; but the American 

 ornithologists regard the birds inhabiting their continent and East Siberia 

 as specifically distinct from those inhabiting Europe and West Siberia. 

 The difference is only one of size, and the variation of both races is so 

 great that the dimensions overlap, although it seems probable that there is 

 a discontinuity of the areas of distribution, as neither Dybowsky nor any 

 other Siberian traveller has met with a Red-necked Grebe in the valley 

 of the Yenesay, where the Sclavonian Grebe alone represents the family. 

 There is no satisfactory evidence that the Red-necked Grebe has ever 

 bred in Iceland, the Faroes, or in the British Islands. In Scandinavia it 

 is a resident south of the Arctic circle, and is a common summer visitor 

 to Archangel, but it lias not been recorded from the lower valleys of the 

 Petchora or the Obb. It breeds in South-west Siberia, Turkestan, and
