Came across this bird yesterday on the Western Isles, Scotland. From the eye color (not very yellow) and overall plumage I assume this is a juvenile, so maybe some features might not yet be as developed as on and adult bird. The bill doesn't show the small, black tip of a scaup, but it seems pretty massive for a tufted. The white on the bill base seems too small for a scaup. And yet, being familiar with tufted ducks, this one seemed "odd". I'm nevertheless leaning towards tufted, but would appreciate confirmation.
Thanks, Simon
