This beautiful duck is sometimes known as the "comb duck" because its bill looks a little like the comb on a rooster and other birds. This duck breeds in the Canadian Arctic, Alaska, Greenland and Siberia. On the Atlantic coast, it winters south as far as Massachusetts. The duck in this picture is a male, or "drake." The King Eider hen has lovely brown, black, and white feathers, and no "comb" on her bill.
