Looking at the male only, but probably applies to female as well.
There is a slight greenish tinge to the dark line on the back of the head (visible in at least two photos) and seems like there is too much white in the outer rectrices, and not a deep-enough chestnut background color to the body feathers to be a full-blooded Mexican Duck. But jury is probably still out on what constitutes a "full" Mexican Duck.

I have a roll of very discolored Ektachrome film which documented some field work and excursions in northeast Arizona in late April and early May 1980. I have been unable to fully adjust the colors to suitable levels.
These images show some of the tall pine forest in the hike country of the Chuska Mts. We visited the area on our day off. The location is not far from the NE rim of the mountsins, probably at about 7500 to 8000 ft elevation.
