American Bison can be incredibly docile in appearance, like this fine specimen that we were fortunate enough to see when we first entered the park. Of course, they are still wild animals and must be given their distance and treated with respect -- this image was shot from farther away than you might think.

Anyway, it seems to me that this guy needs to find a bigger tree to try to hide behind if he wants to avoid the wildlife paparazzi. :)
