Barrow ducks are similar in appearance to the common goldeneye. Adult males have a dark head with a purplish gloss and a white crescent at the front of the face. Adult females have a mostly yellow bill. The male Barrow's goldeneye differs from the male common goldeneye in the fact that the common goldeneye has a round white patches on the face, less black on the back of the bird, and a larger bill. For the females, the common goldeneye has a less rounded head, and a bill in which only the tip is yellow. Egg, Collection Museum Wiesbaden Their breeding habitat consists of wooded lakes and ponds primarily in northwestern North America, but also in scattered locations in eastern Canada and Iceland. Females return to the same breeding sites year after year and also tend to use the same nesting sites. The males stay with their mate through the winter and defend their territory during the breeding season, then leave for the molting site. Mating pairs often stay intact even though the male and female are apart for long periods of time over the summer during molting times. The pair then reunites at wintering areas. In Icelandic the bird is known as húsönd (house-duck); it is a common species of the Lake Mývatn in the north of the country. They are migratory and most winter in protected coastal waters or open inland waters. Barrow's goldeneye, along with many other species of sea ducks, rely on urbanized, coastal estuaries as important places on their migration patterns. These estuaries provide excellent wintering and stopping places during the ducks' migration.[5] It is an extremely rare vagrant to western Europe and to southern North America
