Trumpeters at Washago

We were back at Washago yesterday - what a contrast to Sat Jan 20 -   
 where there had been 100 Trumpeter swans, there were now maybe 10; we saw 8 and there were Trumpeters out of sight, 1 or 2.

We saw 3 fly in about 30 minutes before sunset (17:46) :

There was 1 Goldeneye:

And several Mallards:

I guess that the mild weather has allowed the birds to disperse more.

The Wednesday meeting mentioned sightings of 1 Mute/European swan and a bufflehead.. So I also had my eye open for them. I have seen so many mute swans in my day that they are not problem birds for ID. Nevertheless, I did not see any among the trumpeter.
So my question is: what is this duck:

I have provisionally called it a Goldeneye
