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 × 2.00); May, June.
Range.—Breeds on Labrador and Greenland coasts.
