Comes from living birds
Eiderdown is harvested from wild birds that have already shed it on their own into their nests. They were neither killed nor plucked as is the case with all other types of down that comes from domestic birds. The harvested down is replaced with hay, which does no harm to either the eggs or the nesting bird. Collecting the down after the nesting season would result in it rotting and losing quality. Eider becomes fertile at four years of age and then starts laying eggs and shedding down and it lives up to 24 years. The female eider sheds down every nesting season for all of her fertile life. So, the user of a new eiderdown comforter may rest assured that the birds that gave the down for his item are still alive and well out in their habitat, the North Atlantic Ocean west of Iceland, while the user enjoys the comforters filled with their down. Eiders are a species fully protected by law in Iceland and their nesting places are guarded by land owners, who also are eiderdown harvesters.
