I thought this was a Mallard-American Wigeon hybrid. I have now been informed that, rather it is an intersex mallard (thanks C G Gustavsson).
Intersexes in nature are rare but not exceptional and quite a few similar ducks can be found among internet images, though many are difficult to identify as such. Many intersex Mallards bear a striking resemblance to some Mallard hybrids, especially Mallard x Black Duck hybrids, but can often be told apart by the combination of female-type bill and extensively male-like plumage. Hybrids in contrast, if they show male-like plumage, can also be expected to show a male-like bill.
Wow, who knew?
