720 RED-NECKED GREBE. 
in that country. In Asia it appears to be found as far as Eastern 
Turkestan and Siberia, where it meets with a larger form, distin- 
guished by some ornithologists as C. Aolboelli; and this is the 
representative in the North Pacific, and North America in general, as 
well as in Greenland, where it was first discriminated by Reinhardt. 
A bird obtained in Iceland in December 1885 may have belonged 
to this form. 
The nest is a floating structure, similar to that made by the pre- 
ceding 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: measurements 2 in. by 1°3 in. This bird resembles its larger 
congener in its general habits, diving-powers and food, but its note 
is said to be somewhat louder. 
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, those de/ow the eye 
having white margins which form a strongly contrasted streak ; 
upper-parts dark brown, with a conspicuous white patch on the 
secondaries ; neck in front rich chestnut-red ; breast and belly silky- 
white. Length 18 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 figure below shows the appearance of the foot in the Grebe.
