Eider duck

EIDER DUCK. Somateria mollissima. In Greenland, eiders often nest near tethered huskies - a clever tactic which protects their eggs and young from predators. The female eider lines her nest with soft, downy feathers plucked from her own breast. In Iceland, these feathers are harvested after the chicks are grown and have no more need for the nest. The contents of 85 nests will fill one duvet.
