IMPORTANT: What similar species were eliminated when making the identification and how was this bird different?

Female, first spotted and IDed by Ted Murin. When I arrived, she was fairly far out in the lake and the water was choppy, so far from ideal viewing conditions. I watched her off and on for about 25 minutes. She was mostly swimming but occasionally preened, dove and flapped her wings. She was an overall light brown to tan coloration with the head appearing to be slightly lighter than the rest of the body. She was noticeably larger than the adjacent Common Goldeneyes. ID features consistent with KIEI were thin, white upper and lower borders to the secondaries and no iridescence or white in the speculum, ruling out female MALL (species with most similar body plumage) and all other ducks except eiders. Compared to COEI, this individual had a lighter brown (tannish) plumage and a noticeable angle between the bill and forehead as opposed to the more triangular head and bill of COEI.

Other Notes & Comments

Female. To be honest, if I were IDing this species without knowing that Ted had identified it with his superior scope, I would only rate my confidence level at about 90%. But not knowing how many others might submit an RSD, I thought I would send one in.
