common eider
Somateria mollissima mollissima is a subspecies of common eider inhabiting the shores and islands of the White, Barents, Northern and Baltic Seas. In contrast to its western congener, it nests away from humans, which makes its down the rarest of all mined eiders. It is also the most insulated, as the bird lives in very harsh conditions. Until recently, there was no legal and environmentally friendly collection of this type of down.
