Though wild animals are eaten and killed by scavengers and predators each single day, we hardly ever 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 onerous to look at and onerous 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 onerous to inform if the elk continues to be alive. The cow is in horrible physique situation, with a bedraggled coat and no less than one damaged leg. Weak actions from the cow may very well be mistaken for the grizzly shaking what in any other case seems to be a carcass. However one huge 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 might need been hit by a automotive, ensuing within the damaged rear legs and an apparent lack of ability 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 dwell.
“[Their diet] varies rather a lot by area,” Montana Fish, Wildlife, and Parks bear biologist Jamie Jonkel instructed Out of doors Life in September. “Even right here in Montana, there are various kinds of habitat. For those who evaluate the Yellowstone ecosystem to the Missoula space, it’s completely completely different. For those who 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 quite a lot 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 biggest brown bears on the earth, Kodiak brown bears rely totally on salmon and different fish of their food plan. Grizzlies in Montana and Wyoming eat quite a lot of meat from ungulates, like elk.
“Bears use probably the most nutritious elements of their meals to maximise their weight achieve,” the Alaska Division of Fish and Sport explains in a reality 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 popular elements of the salmon. Inner 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 probably the most nutrient-dense a part of a prey animal, so this bear may very well be feeding on hindquarter meat, or it may very well be consuming the elk’s intestines and colon. (Wolves exhibit related conduct 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.
