Side Charge
Two bull moose spar in Grand Teton National Park. This looks like a violent scene but they are just 'playing', or so that's what they should be doing this time of year.
Actual fights over females during the mating season can be very sudden and violent. Once mating season is over however, the males quiet down and hang out in groups.
These two were still quite feisty and the smaller bull decided to charge the bigger bull from the side!
