Muscovy Duck I think

Any help would be gratefully recieved as This could be the first Muscovy Duck I have seen in the wild.

Could it be a Muscovy Duck Crossed with a Domestic Duck as the body was completely white and the duck was well away from a large group of Canada Goose all the duck wanted to do was sleep.

Its a pure Muscovy.They come in several colours, from pure white to pure black, also black/white, several shades of Lavender/grey/blue and now brown and fawn too. They will hybridise with Mallard-type ducks but the offspring are always infertile- the hybrids normally don't have the face wattles either which is why I say its a straight Muscovy(a male by the look of it.)

They tend not to associate with other species of waterfowl, just with their own kind.
