326 THE NESTS AND EGGS OF 



that the breeding areas of the present species and the 

 Sclavonian Grebe are to a great extent distinct, so 

 that the locahty is of some assistance in identifying 

 the eggs. 



Family PODICIPEDID^. Genus Podiceps. 



SCLAVONIAN GREBE. 



Podiceps cornutus {Gjfielin). 



(British : Possibly breeds : Nomadic autumn and winter migrant.) 



Single Brooded. Laying season, June. 



Breeding area : Northern Nearctic and Palsearctic 

 regions. The Sclavonian Grebe breeds in Iceland, the 

 Faroes, and throughout Europe in suitable localities 

 north of about lat. 54° up to the Arctic Circle, except 

 in Scandinavia, where owing to the influence of the Gulf 

 Stream its range extends beyond that limit. Eastwards 

 it breeds in South-western Siberia, the Baikal area, 

 Dauria, and the valley of the Amoor. On the American 

 continent it breeds in Alaska, and throughout British 

 North America as far north as the Arctic Circle. It 

 may also breed in the south of Greenland. 



Breeding habits : The Sclavonian Grebe is a 

 migrant, and returns to its summer haunts late in April 

 or during May, according to locality and state of the 

 season. I cannot find that this Grebe is gregarious 

 during the breeding season ; it lives in more or less 

 scattered pairs, each keeping to themselves although 

 nesting in the vicinity of others. Its favourite breeding 

 grounds are lakes and pools, where the sides are shallow 

 and clothed with a luxuriant growth of reeds, sedges,
