Description of the Bird

Overall gray with dark cap and pale cheeks and thin bill. Tail erect. Do not think the bird was dark enough to be adult female.

Similar Species Discussion

Eliminate from other scoters due to shorter thinner bill. Lack of vertical white patch that and dark eye eliminated Surf Scoter. Lack of white lores and white secondaries eliminated White-winged Scoter.
