Although there was a similarity of head profile to the Common Eider, the facial spots eliminated any eider. Black Scoter would have a more rounded head with a uniform lighter cheek area as opposed to the spots on this bird. White-winged Scoter should have shown more rounded angle form the top of the head to the bill, generally would have less distinct facial spots, and definitely would have had white wing patches when the bird raised its wings. | The original documentation form event lasted from 09:50:00/10:05:00.
