The surf scoter is a stout sea duck. Adult males weigh about 1050 grams (2.3 lbs) and females 900 grams (2 lbs). Adult males are distinguished by their bright, bulbous, multi-colored bills, lustrous velvety black plumage, and conspicuous white patches on the forehead and the back of the head/neck. In immature males, bill coloration is less dramatic than in adults and the white head patches tend to be either entirely absent or much smaller in size.
