Re: [cobirds] Re: Mexican, Mallard, Mottled?

I will go out on a limb and suggest that this is a candidate for Mexican x Mottled based on the appearance of typical male Mexican Duck except for three traits inherited from Mottled Duck: moderate black gape spot, purple tinge to blue speculum, and buff patch on throat. Are these all within the range of variation for Mexican Duck - possibly (I don't know). I suggest posting to the bird hybrids facebook page for more opinions.

New photo showing speculum of same bird in question  https://ebird.org/checklist/S100849831  To me the speculum looks like typical Mallard.

Looking for some thoughts on this.  The duck has been observed by several birders in Chaffee County just west of the 163 pond hotspot in a small pond area.  Whether this is the same duck reported as a Mexican on Dec. 29 by Jack Bushong on 163 pond is unknown.  After perusing many discussions about this "complex" I'm curious as to what people may think about this individual.  See photos on my ebird checklist https://ebird.org/checklist/S100712744 and also on Greg Mihalik's checklist https://ebird.org/checklist/S100667677.  Looking more closely at photos I realized that there is also a dark gape spot just to add to the question.  So far, no speculum photos.
