Common Eiders are a large duck often seen in large flocks floating along the coast. In Iceland, down from the nest is collected during incubation and is used commercially. Eiders use the down to line their nests. Rather than killing the eider, humans have learned to take the down a few days after the young leave the nest. Males often winter farther north than females and immatures.
