Male Bison Fighting in Yellowstone

Occurred on August, 2016 / Yellowstone National Park, Wyoming, USA

Info from Licensor: "I was driving, when I saw this 2 male Bison fighting on the side of the road, most likely in a dispute for a female, as this video was shot in august, which is mating season. I was able to get really close to the animals and film it from my car window."
