The documentation form by Andrew S. Fix is the only one submitted and forms the basis of this record. Other observers include Craig Harms. | Elimination of similar species: By general shape, bill characteristic, and color this bird was identified as a scoter. The white/creamish spot between the cere and eye and lack of pale cheeks and throat ruled out the Black Scoter; the bill was Also too extended up the forward part of head for a Black Scoter. I did not feel comfortable differentiating Surf from White-winged based on the morphology of the head. No white wing patch was evident while this bird was on the water. In my experience (see #14), the white patches on the heads of female and immature scoters are very unreliable and highly variable. Fortunately the two key characteristics were plainly visible when the bird flew; paddling along the water for a short distance (confirmed scoter), and prominent white secondaries (confirmed white-winger scoter) | The original documentation form event lasted from 14:00:00/14:15:00.
