Massive bull bison tosses Yellowstone tourist into the air like a ragdoll in shocking attack

“I was just trying to get some dramatic footage of that bison having a fit. It’s changed my idea of what to expect from these guys at this time of year, because I would not have predicted that happening,” Montana-based photographer Mike MacLeod, who took the pictures, told Cowboy State Daily.

“He [the bison] started walking through the campground. He was coming up to this group of kids, who were taking pictures on their cellphones from a good distance away, and then the buffalo charged these kids,” MacLeod said.

The photographer stepped in to try to scare off the animal.

“I had to get the bison’s attention. I was really afraid he was going to gore the guy on the ground, so I stopped videotaping and ran at the bison, yelled loud, and was trying to be as big and intimidating as possible,” MacLeod said.

When the bison was gone, MacLeod and others rushed to help the victim.
