help Spectacled Eider FAQ
Why is the Spectacled Eider named that?
It gets its name from the distinctive, pale green "goggles" of feathers around its eyes, giving it a spectacled appearance. This feature is especially prominent on the males, making them highly distinguishable from other sea ducks.
Where do Spectacled Eiders spend the winter?
After breeding in the coastal tundras of Alaska and Siberia, they migrate to the Bering Sea to spend the winter in dense flocks. They spend months congregating in small openings within the winter sea ice, diving for clams and other invertebrates.
Is the Spectacled Eider an endangered species?
The species is currently listed as "Near Threatened" due to significant population declines observed in the late 20th century. Scientists are actively studying how climate change and melting Arctic sea ice are impacting their specialized wintering habitats.
How deep can a Spectacled Eider dive when foraging?
Spectacled Eiders are capable divers, often descending to depths of around 40 to 60 meters to forage on the ocean floor. They use their wings to propel themselves underwater while hunting for crustaceans and mollusks.
