This was an albino mallard duck, I have only ever seen this one. I really didn't think as much of how unique and rare this was at the time. I have seen hundreds of different ducks over the years, and all of them had their normal patterns. It was a fairly friendly duck and did come up to me a couple of times, which they don't usually do. I believe it could have been a female, but I really don't know; the brownish parts of its feathers seem to match the lady mallards the closest.
