After posting a comment on

After posting a comment on this observation today http://ispot.org.uk/node/17815 I had the chance to photograph these two birds when I went out in the afternoon.
I also heard two reports of Scaup locally; one of 2 females which may turn out to be white-faced Tufted Duck, and one of a possible male seen distantly on local reservoirs - which is probably a genuine report of one seen by myself and others a few days ago.

The one on the right does

The one on the right does look dome headed for female Scaup and the other is a drake tufted duck.

Tufted Ducks esp females do show some white at the base of the bill

Compare with these two

Although the head does look fairly rounded from this angle, the righthand bird is a female Tufted Duck. The lefthand bird is not a pure male Tufted Duck, which would have a black back and (at this time of year) an obvious crest on the head. Compare with the birds in this observation; http://ispot.org.uk/node/16970

Probably male Tufted Duck x female Pochard.

Although this bird may be a Scaup x Tufted Duck hybrid, the parents are perhaps more likely to be a male Tufted Duck and a female Pochard, as this cross can produce male offspring that look very like this individual.
