Well, here’s something you don’t see every day.

Photographer Daryl Hunter has posted a pretty perplexing video of elk and a grizzly bear behaving in a way that seems — well, you’re just going to have to watch it.

In Hunter’s video, a grizzly bear in the Willow Flats area of Grand Teton National Park strolls into frame and, understandably, a bunch of elk trot briskly in the opposite direction. But then, something really weird happens. The grizzly does not give chase, and the elk walk right back up to the bear. Then the bear appears to wander around the herd for a few minutes, all without the bear or the elk doing what you would expect.
