Regardless that wild animals are eaten and killed by scavengers and predators each single day, we not often get a front-row seat to this course of in motion. That’s why a video posted to Nature is Steel’s Instagram account on Saturday is each exhausting to look at and exhausting to look away from. The footage exhibits a cow elk mendacity on her facet as a grizzly bear feeds on her rump.
At first, it’s exhausting to inform if the elk continues to be alive. The cow is in horrible physique situation, with a bedraggled coat and a minimum of one damaged leg. Weak actions from the cow could possibly be mistaken for the grizzly shaking what in any other case seems to be a carcass. However one large eye and ribs rising as she breathes are proof that the elk is hanging onto life even because the bear goes to work.
Wyoming wildlife photographer Kevin Fuchs captured the footage and posted it to his personal Instagram profile this spring, together with a viewer discretion advisory.
“This grizzly bear was seen earlier on this elk that had earlier accidents consisting of 1, if not each, again legs damaged,” Fuchs writes within the video caption. He guesses that the elk may need been hit by a automobile, ensuing within the damaged rear legs and an apparent incapability to flee the bear.
Grizzly bears, like all different bear species, are omnivores. Along with recent meat, carrion, and bugs, they eat roots, berries, forbs, and different vegetation. Their diets additionally shift relying on the ecosystem the place they stay.
“[Their diet] varies loads by area,” Montana Fish, Wildlife, and Parks bear biologist Jamie Jonkel advised Out of doors Life in September. “Even right here in Montana, there are several types of habitat. Should you evaluate the Yellowstone ecosystem to the Missoula space, it’s completely completely different. Should you go to the north round Glacier [National Park] and Libby, it’s completely completely different. Then you definately exit to the coast in Alaska, and that’s completely different. There’s loads of variation on the market.”
Regardless of that variation, meat is a requisite meals supply in each a part of a grizzly bear’s vary. The most important brown bears on this planet, Kodiak brown bears rely totally on salmon and different fish of their weight loss plan. Grizzlies in Montana and Wyoming eat loads of meat from ungulates, like elk.
“Bears use essentially the most nutritious components of their meals to maximise their weight acquire,” the Alaska Division of Fish and Sport explains in a fact sheet about Kodiak bears. “Grass and forbs are solely used whereas they’re quickly rising within the spring and early summer season. Brains, flesh and eggs are most well-liked components of the salmon. Inside organs of deer, elk and cattle are eaten first when one is killed or scavenged. Berries are used most frequently when they’re ripe and sugars are at their highest stage.”

Which may clarify this explicit grizzly’s conduct. Organs are essentially the most nutrient-dense a part of a prey animal, so this bear could possibly be feeding on hindquarter meat, or it could possibly be consuming the elk’s intestines and colon. (Wolves exhibit similar behavior when looking, and are even recognized to tug fetuses from the wombs of pregnant does or cows.) This video is a stark reminder that predators and prey will do no matter they will to outlive.
