RED-NECKED GREBE. 



land — where it was first discriminated by Reinhardt. A bird 

 obtained in Iceland in December 18S5 probably belongs to this 

 form. 



The nest is a floating structure similar to that of the preceding 

 species, in the company of which the Red-necked Grebe may often 

 be found breeding in Northern Germany ; the eggs are dull white, 

 and elliptical in shape, as are those of all the members of this 

 genus : average measurements 2 by i"3 in. The note is said to be 

 somewhat louder than that of its larger congener, which this bird 

 resembles in its general habits, diving-powers and food. 



The adult has the bill dark horn-colour, yellow at the base ; 

 irides yellowish-white ; crown, nape and hind-neck blackish ; 

 feathers of the cheeks, chin and throat grey, with white margins 

 which form a strongly contrasted streak bjio'(i> the eye ; upper parts 

 dark brown, with a conspicuous white patch on the secondaries ; 

 neck in front rich chestnut-red ; breast and belly silky-white. 

 Length 16 -5 in., wing 7 in. In winter the throat is greyish-white; as 

 it also is in young birds, which are duller in general colour. 



The fisrure below shows the form of the foot in the Grebe.
