Thanks so much for your input. It is much appreciated.
What SCI does re: Coues taxonomy is interesting (maybe even acceptable) but not necessarily biologically driven. Instead, my experience with B&C tells me their taxonomy designations may be based more on biology rather than trophy-member accolade.
However, in general, I maintain the "state of the art" for accurate Coues designation (in my unprofessional opinion) is still wanting.
For example, I hunted Gould's turkeys in Aguascalientes last spring, and also enjoyed the opportunity to observe lots of whitetails. Leaning on 11 consistent years of hunting Coues deer in Sonora, it occurred to me that the whitetails I saw in Agus. looked & acted exactly Sonora Coues.
Therefore my question.
The ranch owner in Agus. confidently asserted his deer were Coues. He is credible, believable, educated, realistic and sophisticated.
So, what's a guy to do? Were the deer on his ranch Coues or some other subspecies of whitetail?
If they aren't Coues, what are they?
Thanks folks.
