Eiders breed very well at Martinmere. Most
get reared in the nursery but some nests do go undetected with broods
being raised on the lakes. (photo below)
The juveniles below are being raised in
the nursery
Eventually the young ducks are released
onto a lagoon of their own whilst they mature further. These juveniles
are about 3 months old. It will be two years before the males develop
their fine adult plumage.
