Looking at sea duck

A female Stellar's Eider, was present & photogaphed at Morfa Nefyn, Gwynedd on Saturday & Sunday. The bird could not be found today & there is a chance that it has moved down the coast, perhaps to Pembs.
If out on the coast please report all ducks/sea ducks.
Numbers of sea duck are very low this winter, with only Common Scoter on the sea being seen?? Hope that I am wrong!
(has the Eider in Angle Bay gone?)
