Mallard??? Nope, not quite! This is a hybrid mallard. I sent the first 2 photos over to the NC Museum of Natural Sciences on their Ask a Naturalist site and asked did they have any ideas what the parentage was. They said they felt that it was mallard x muscovy duck x Graylag goose. Mallards often cross breed with other duck and goose species. My goodness what a mixture. However, quite a gorgeous bird to see. Third photo is a normal mallard so you can see the difference.
