As spring approaches the young bulls are starting to annoy the elder statesmen that surround them in Yellowstone National Park. The struggles are more show than real aggression. We were fortunate to observe these magnificent animals for a week and they have so much personality. Each one is different, except none of them seem be morning “people”. We were up before the sun everyday to catch the early morning light and the bison were not happy about it. We even had one give the car a little head butt just to express his displeasure at being passed by on the road.
