I posted a picture I took of Muscovy ducks that I took in this same farm pond a couple of years ago. I have a few as they cooperated more than I expected and hoped out of the pond right up to me. I have seen them a couple of times since but couldn't take a pictue because all I had was my cellphone and thought it would have a problem at the distance or just didn't have time. So I stopped with my guest. I believe these are domesticated.
Great shot. I like their colours - at least this one. I see them here and I always thought they have some sort of ailment with the red bumbs on their head.
