Hehe! Yes! He is wondering why you are taking up his air! I have only seem buffalo out west, and sparsely at best. The no color rules works wonderfully here, taking advantage of the light.
I must say that I would never have thought it, but, I actually favor the sepia becuase it truly does look timeless there, in fact, it could have been in my grandparents time. It truly gives it that old fashioned, yesteryear look that works so well with a nearly gone at one time species.
Great shot!
Happy Saturday!

Thanks so much Denise and for your generosity! The buffalo are normally quite peacefully unless there is a baby calf in their midst. They are very protective then or if anyone invades their territory.

The sepia could have been taken in the olden days when the buffalo freely roamed the plains before they were senseless slaughtered at a terrible rate.
Tha calf stays an orange color for awhile. This is part of the same herd.
