There was a car blasting it's horn to get a reaction from the bison which is why it got pissed, I heard, when it couldn't get the car it decided to go for the nearest other people.

Bison are extremely territorial, and have awful eyesight. People forget that they’re literally bulls. The same bulls that famously charge and gore people for being too close to their bullpen. The same bulls that have entire arenas designed for a trained person to fight them. People will see a bull amongst a herd of cattle, and recognize that he will fuck their shit up just for being too near the herd. They’ll respect the animal, because they know he’s going to be territorial.

But apparently all of that goes out the window when people are around bison. Bison are territorial towards basically anything even remotely as tall as they are. And they have awful eyesight, so they tend to interpret people as territorial threats. They’re also the size of a fucking sedan, and can easily outrun a person in a short sprint.

The dude in this video only lasted as long as he did because he wisely used the trees as cover. He used the bison’s size against it, by hiding between the trees where the bison couldn’t easily charge directly at him. But he was stuck in the smaller saplings, while the bison was able to just charge straight through them. His best bet likely would have been to stick near the larger trees, where he could at least keep using them as cover.

Did you see the way they looked at the bison?!

It was.
