Loser: Spectacled Eider
Specialized needs put these northern ducks at risk. In winter, the birds gather in a small, cold, nutrient-rich area of the Bering Sea to dive for clams and other marine life. But as ice retreats, spectacled eiders' habitats and access to food resources in their wintering grounds are changing. Meanwhile, coastal changes are altering the ducks’ breeding habitat on tundra wetlands.
