Clangula hyemalis

• The male common goldeneye permanently leaves the nest midway through incubation and flies to coastal areas, where it joins large same-sex flocks during molting.
• In the wild, the common goldeneye lives 15 years, but its maximum lifespan is 22 years.
• Young common goldeneyes begin foraging immediately after birth, pecking insects from the water's surface or diving. Sometimes the female helps them by dislodging sediment from the bottom to the surface.
• The common goldeneye's nest is usually located near water, but almost always on dry ground. The female lines the depression with down plucked from her breast.
