Watch: Yellowstone wolf bites grizzly bear in the butt

A Yellowstone National Park tourist on Saturday captured video footage showing a wolf repeatedly biting a grizzly bear’s butt.

The distant footage, captured by Gary Gaston in the northern portion of the park, also reveals a bear whose best defense seems simply to sit and become less vulnerable against the quicker wolf.

Gaston told FTW Outdoors that there was a large animal carcass – “probably an elk” – in a nearby thicket, which explains the presence of wolves, bears, and ravens in the same area.

“The bear sat down after it was bitten, then as soon as the wolf walked away it did too,” Gaston said.

As Gaston noted on Facebook, the footage was captured at daybreak at Crystal Creek near Slough Creek. “Crazy wolves, these,” he joked.
