Dettagli dell'osservazione
First attached photo depicts 3 female Eiders. While I had never encountered one, the middle duck appears to bear three characteristics of a female King Eider: 1. The bill appears black 2. the head appears rounded and 3. the duck in question seems to lack a long, sloping forehead like the female Common Eiders flanking it. 2nd attached photo is a cropped enlargement depicting a female Common Eider on the left and the Eider in question on the right.
