№ 101-103. Ducks. The extended series.

The Siberian Eider is a sea duck of middling size. It is rather silent. It flies 30-50 meters higher than water surface. It lives at the fleet lakes of the seaside tundra and at the sea. There is a bright "mirrow" with blue reflections on the wing of each bird.

There is information that common eiders live on the northern seaside of West Siberia. It has the best eiderdown among birds. Due to its unique levity and poor heat-transfer capacity the eiderdown is famous as the best natural warmer in the world.

King Eider inhabits almost all the northern tundras in Russia, and also arctic islands of the Northern Ocean, Greenland and North America. King Eders spend winter in Atlantic.
