I know this is a terrible picture. It was taken with a zoom lens, in a hurry from the car. These ducks have been here at least 2 months, they're in a shallow water pond (water is not over 2 ft at any point in this pond) and are very spooky. They have either dark green or black on their butts and have red over their eyes, but they are NOT muscovies. They are about the size of a mallard.
I thought they were gadwalls at first.
