Grizzly Bear Hunts with Wolves—and Eats Their Kill


An uncommon inter-species interplay came about in Yellowstone Nationwide Park this fall, and Nationwide Park Service (NPS) biologists have been capable of seize it on movie. In October, a grizzly bear was reportedly seen operating—and even searching—with a pack of wolves. “On the morning of October 21, 2021, guests watching wildlife in Yellowstone’s northern vary have been amazed once they noticed an grownup grizzly bear seemingly searching elk with the Junction Butte Wolf Pack,” writes Yellowstone Nationwide Park Service in a Facebook post on December 15. “Wolves and bears sometimes compete with each other for prey, so why may this be taking place?”

As an alternative, a gaggle of wolves from the Junction Butte Pack, which is without doubt one of the park’s most well-known, efficiently takes down a cow elk, no because of the grizzly bear. However the bear quickly exhibits up on the scene of the wolf’s kill and efficiently pushes them off of their it to feed.

“Usually, wolves will yield to incoming bears. Since searching is harmful and sometimes unsuccessful, it’s higher for wolves to attend their flip at a carcass that has been usurped by a bear than it’s for them to proceed searching,” explains the Yellowstone NPS. “From the bear’s perspective, it takes a whole lot of power to comply with a wolf pack round, however the reward is excessive if it efficiently takes over a carcass. A contemporary elk carcass is an excellent supply of fats and protein for a grizzly bear making ready for hibernation. This bear appears to have found out that following the wolves within the morning will enhance its possibilities of encountering a high-calorie meal.”

The Yellowstone NPS calls the latest interplay between the grizzly and wolves a case of “kleptoparasitism,” which accurately interprets to parasitism by theft.
