- Cool Facts
- The Pacific form of the Common Eider is distinct genetically and morphologically from the other forms, and may be a different species. The male has a thin black V on its chin and a bright yellow or orange bill.
- Mother Common Eiders lead their young to water, and often are accompanied by nonbreeding hens that participate in chick protection. Broods often come together to form "crèches" of a few to over 150 ducklings. Attacks by predators may cause several broods to cluster together into a crèche. Once formed, a crèche tends to stay together throughout the brood rearing period, although some of the different females attending it may leave.
- The oldest recorded Common Eider was a male, and at least 22 years, 7 months old, when he was found in eastern Canada.
