It's domestic hybrid, looks like a Pekin/Muscovy/perhaps even domesticated Mallard mix-undoubtedly progeny of dumped Easter ducklings

As mentioned I had seen some pairs closer to the road on another local deep pond earlier in the week. They were mixed in with some common mergansers. Definitely a green head on the drakes. At a quick glance I mistook them for mallard drakes, but seemed very strange that they were mixed in with Common Mergansers (who seem to really dislike mallards) So probably is Greater Scaup, Rendering from WhatBird.com. I think this is it.

I need help IDing a duck. It was slightly larger than a mallard, had a pink bill with black/brown mottling/ had a black head with a white ring around the eye, a white ring around its neck, a light grey back, its legs seemed to be set further back on its body than the mallard (which leads me to believe it may be a diving duck?) and were a brownish grey color, and its tail was fairly wide and stuck up like a ruddy duck, but it was WAY bigger than a ruddy duck and other than the tail, looked nothing like a ruddy duck. It was the only one of its kind with some local mallards (4-5 drakes in eclipse plumage, 4-5 females, and about 5 or 6 of this year's juveniles), in a slow moving small creek (maybe 20-30 ft across and maybe 3 ft deep at the deepest). Can't figure out what this duck is, maybe a hybrid, a juvenile, or a drake in eclipse plumage, or some combination??? Any help or directions to who (or where) I should go for help would be appreciated!
