Identification of escapee ducks

[Kneedles]

These are all ducks that I saw in wild or semi-wild states, but are clearly derived from domestic breeds of duck. I would appreciate help with their identification. Thank you in advance.

Could this be a Khaki Campbell hybrid?


I believe that this may be a Muscovy X Pekin hybrid.


This one could be a wild colour morph, or a Domestic X Wild Mallard hybrid of some sort, but I am not sure.

I don't think I could make much better guesses than yours.
