The feathers of the sides of the bill of this species do not reach to the nostril, while in the two preceding ones, they do. This is the chief point of difference in distinguishing the females, which very closely resemble each other. Adult males, as can be seen, are very different from the other Eiders. As is usual with the Eiders, the male of this species moults to a plumage resembling that of the female, during the late summer, when he has shed his wing feathers and is, for a period flightless. This is a part of Nature’s plan to give her feathered children protection when they most need it. While the females are sitting upon the eggs, they are deserted by the males, which congregate in large flocks, and drift aimlessly about until joined by the females in Fall.
Nest.—A depression in the ground, lined with feathers. Eggs like those of the last species.
Range.—Breeds from northern Labrador and the Aleutian Islands, Alaska, northward; winters south to Maine and casually to Long Island Sound.
