Hanging around with Tufted Ducks. Large amount of white at base of bill. Could be either!
No interactions present.
Both birds appear to have this plumage
White patch at the base of the bill is a feature of both Scaup and some Tufted. Is however, less obvious on Tufted. Scaup is a larger, 'rounder' more buoyant looking duck, rather like a Tufted on steroids. It really is a case of when you see one, you will know!

The extent of black at the tip of the bill confirms that this is not a Scaup.
I was certain it was a Tufted really. Just hoped i'd got lucky!
