NORTHERN EIDER 
159. Somateria mollissima borealis. 23 in. 
Base of bill extends on either side of forehead in a 
point, a mark that will distinguish it from the next 
and very similar species, in any plumage. The female 
Eider presents a most remarkable difference in plumage 
from that of the male, and, unlike the females of most 
species, is a very handsome bird. 
Nest.—Of grasses lined with down: concealed in tall 
grass or under bushes; the 6 to 10 eggs are greenish- 
drab (3.00 x 2.00); May, June. 
Range.—Breeds on Labrador and Greenland coasts. 
AMERICAN EIDER 
160. Somateria dresseri. 23 in. 
This is the Eider that is usually seen on the Atlantic 
coast and is the only one that breeds south of Labra- 
dor. The base of the bill, that encroaches on either side | 
of the forehead is rounded, and broader than that of 
the last. They nest from Maine (rarely) northward, 
and winter south to Long Island.
