Elie, first and foremost, your photos are phenomenal! I’d like to even consider painting the second one of the bison, if that’s okay with you. Your post is very interesting, as well.
However, as I have a mild obsession with bison, I would like to point out — bison aren’t actually buffalo, even though we Americans often call them that. True buffalo live only in Asia (technically / scientifically, the American critter is “bison bison” while the Asian version is “bison buffalo”).
