    Just to chime in with what Patrick and Greg have already said...there is a Mallard very similar to what you describe that lives in front of the CT River Museum on the CT River at the Boat launch in Essex.  He's very big and dark (25% bigger than other Mallards) with typical male Mallard head markings....and this duck only associates with the domestic geese (Greylag geese) there, even though there is regular flock of semi-tame Mallards there. This giant Mallard is called Duck-goose by the locals and is something of a curiousity.  A first glance he appears to be a giant Mallard but there are differences in the body plummage and bill color. He constantly tries to mate with a big White domestic goose and challages the Greylag geese by lowering his head and running at them. He amuses the locals daily.

On the way home to Somers stopped at the Mill Pond in Broad Brook to check out more ducks and saw one in with the mallards that had a green head but a white chest. Looked in the book to confirm a northern shoveler but a couple things didn't look quite right. The duck was slightly larger than the mallards (book says they are smaller) had a green head but an orange/yellow bill instead of dark (even with the scope he was pretty far away to see if the bill was really shovel shape) and his body was pretty dark (no sign of rusty sides) with a hint of white perhaps along the wing edges (I didn't see him fly though). My first thought was he was a hybrid of a mallard and something else because I couldn't quite convince myself he was a
Any thoughts anyone?
