Pronghorn?

I have been told to check my eye sight. I have been told I was crazy, but this morning makes two mornings in a row that I have watched a pronghorn antelope wandering about the fields between Spangle and Grey Place.

I have confirmed the black horns, the white butt and belly, the distinct head bob when he walks slowly. It is a pronghorn. I am not crazy (at least in this particular sense), but I wonder what the old boy is doing out here, all alone and wandering about.

My long lens doesn’t do well in early morning light, but the best proof I can muster is below.
