Mexican Duck or Mallard? (1 Viewer)

Hello All,
I saw this bird in May 2021 at Lake Cochise, Willcox, Arizona. Want to confirm whether this is a Mallard or a Mexican Duck. Can someone please help with the ID?

I am no expert on these, but I'm fairly sure that this is NOT a regular mallard. Notice that the bill is pretty uniformly dark yellow (ruling out female mallard), the overall coloration is fairly dark (darker than female mallard as well). A quick look at eBird indicates that in the location you saw it there have been reported hybrids, so I suppose that is also a possibility.

I would go with Mexican duck. The sharp line between light tan on throat and body, and the eye line are two things I used to look for when I lived in SE Arizona

These are also features of black duck and are variably prominent in wild-type/pure mallard - so the fact that this bird shows them doesn't really close any options.
