It’s usually just the male bison fighting during the rut, but sometimes the moms get feisty too! This is from earlier this spring in our yard near Yellowstone #yellowstone #wildlifephotography #Montana #wildlife #nature #naturephotography | Trent Sizemore Photography

🐮 Two Male Bison Battle in Yellowstone National Park

BISON VIDEO: Officials at Yellowstone are saying it is bison mating season and the male bison are very aggressive right now. Remember to keep a distance of 25 yards from all bison and elk and 100 yards from other wildlife. Thanks to Yellowstone National Park for this video.
