Breeds in the North Georgian Islands, but is by no means numerous, and 
a single specimen only was obtained ; this individual corresponds with the 
accounts of authors, excepting that the white plumage of the breast and 
thighs is intermixed with the same yellow feathers as on the crown and hind 
head, though not quite so deep in colour. Those of the crown are rather 
golden than yellowish as they are usually described.

Breed in great numbers on the islands in the Polar Sea. The plumage of 
the female is less vivid during the height of the season than that of the male ; 
she is also rather smaller, the average difference in their length exceeding an 
inch. 
26. Anas Spectabilis. King Duck.

This species as well as the preceding are very abundant in the North 
Georgian Islands, having their nests on the ground in the neighbourhood of 
fresh water-ponds, and feeding on the aquatic vegetation. The egg is 
shorter than that of the Eider Duck, rather broader across in the widest 
part, and more tapering ; of a cinereous olive colour, not whitish, as stated 
erroneously by Montague, but less green than the egg of the Eider. Mr. 
Temminck’s description of the male bird is generally correct ; but he has 
omitted to notice the peculiarity of the tertial feathers of the wing, which curve 
outwards in a remarkable manner over the primaries ; nor can the colour of the 
wings be called a deep black, being ferruginous, especially in the inner webs.
