We did enjoy watching two male deer try to sling mud onto their backs with their antlers. Occasionally they would have a little sparring match when the older one thought the younger was getting a bit pushy. They also had fun with a large branch that was in the water, lifting it with their antlers and throwing it around. The does and fawns just hung out in the shade nibbling on cool grass. I suspect they were rolling their eyes a bit too.
One of our favorite places in the zoo is the butterfly tent. It's only open in the warm weather. It was surprisingly free of sticky ankle biters so I managed to get a few pictures in spite of the butterflies who were not too cooperative. Either they would not settle down or were shy and tried to hide behind the leaves. I needed a faster camera (Please note this fact for the Xmas season) but here are a few successful moments.
