Bears are fighting in the Canadian wilderness, as this absolutely insane video shows.

There are grizzly bears in Northern Canada. That might not come as a surprise to anyone who actually lives there, but what might come as some surprise is that the male bears will get into tussles throughout the year. They’ll fight over territory, the best feeding grounds (especially when it comes to the annual salmon rush), and of course, female bears.

We don’t know what started this fight, but we do know it was caught on cell phone thanks to Facebook user Cari McGillivray, who posted it on her page last Friday. The footage was taken on the Stewart Cassiar Highway near the Alaskan border and shows two male grizzlies duking it out.

At first, the two bears remain on all-fours growling at each other, but things quickly escalate when they start baring their fangs and tilting their heads. When one of them gets on his hind legs to appear larger, the battle is on. The other bear rises and pushes the second one in a way that seems very reminiscent of how a human male will goad another into combat by pushing them. Then the other bear pushes back before a brief but violent exchange of blows.

"Don’t normally post on here but thought I’d share this incredibly rare and amazing moment with all you guys of these grizzlies fighting,” Carli wrote on her Facebook page. “Keep a sharp eye out for the little wolf that is observing them in the distance!"

You can see a grey wolf in the distance crossing the highway and trying to look inconspicuous as the two great bears settle their differences. Eventually, one bear falls over in a ditch and the other pounces on top, biting and pummeling with his giant paws. This seems to take the wind out of the sails of the second bear that then retreats off camera.

The video has over 3.6 million views and 77,000 shares on Facebook since it was posted. These bears are stars, wherever they are.
