Bison calves frequently play together in ways that mimic the ways of adults, such as head-butting or one climbing onto the other. Not only was the calf on the left not as into playing as the one on the right, but it was substantially smaller to boot. Not to worry, they were playing under the watchful eye of one of the cows.

An attempt to combine the tight portraits of the face from the previous pictures, but also show the varying shades of brown in this bull’s fur. It’s a touch too tight in my opinion but not only did I not have time to take the teleconverter off the big lens, but it was extremely dusty and not the best place to be exposing the innards of the camera.

This is why I think the built-in teleconverter in Canon’s announced 200-400mm lens is so brilliant. Oh what a joy it would be if my 500mm had one! It would solve one of the biggest and most frustrating challenges I face, regardless of whether I’m in the Tetons or Ridgefield.

I could photograph bison all day long but it’s not an addiction, of this I assure you.
