America’s first national park, Yellowstone National Park, was founded in 1872 and is mostly located in Wyoming. The marvels that surround you in this national park are unlike anything other. Visits to Yellowstone are like entering another universe; it is our first national park and a wonderful wonder to see.  This genuinely exceptional national park is full of wonders, from natural wonders like the Yellowstone Grand Canyon to fauna like the nation’s biggest herd of buffalo, brown bears, and wolves. A Youtube channel by the name of “Caters Clips” shows us just how intense things can get with the wild animals there. Their video of a bison and a grizzly bear interacting has nearly 5 million views at the time of writing this. This isn’t just any video. On Sunday, May 31, 2020, Michael Daus (55) was at Yellowstone National Park with his family. While walking around the park, they spotted a bison grazing in the distance.  Grass and sedge make up the majority of an American bison’s diet. It will consume fruits and lichen on occasion. Without knowing any better, a young grizzly bear cub runs up and attacks the bison while it’s eating. Despite being young, the bear is nearly the same size as the bison! 

Wildlife Sizing

Male bison, also known as bulls, may weigh up to 2,000 pounds and grow as tall as 6 feet; in contrast, female bison, also known as cows, can weigh up to 1,000 pounds and grow as tall as 4-5 feet. At birth, bison calves weigh 30 to 70 pounds. 

Grizzly bears may weigh more than 700 lbs (315 kilograms). The males may weigh up to 1,700 pounds, making them bigger than the females (770 kilograms). An enormous female can weigh up to 800 pounds (360 kilograms).

The Fight Goes On

The altercation between the two animals gets intense, with the bison charging at the bear. That doesn’t deter this young grizzly, as he repeatedly comes back for more! The two eventually fight their way over a bridge, along the prairie side, and eventually downstream. While it may appear relatively harmless, the bear isn’t giving up and the bison is clearly irritated. Even in the water, the feisty cub continues to attack the bison, almost looking as if he’s going to climb on top of him.  For tens of thousands of years, bison and some species of brown or grizzly bear lived side by side. Any animal, but especially not a grizzly bear, finds it difficult to kill a bison. We’re just glad this cub’s parents weren’t around to join in on the action. Check out the spectacular video below to find out who prevails in this fight!

Do Brown Bears Normally Fight Bison?

In spite of an overwhelming preference for meaty fare, and the delightful abundance of carcasses abandoned by wolf packs, brown bears have been known to hunt larger herbivores. Included on that list are weakened elk. Bison, are somewhat trickier given their penchant for wandering in herds, the immense bulk of males – not to mention their reputation for being especially foul-tempered. And yet, certain Yellowstone grizzlies have perfected the art of hunting down these mighty herbivores. That said, they are generally more likely to target a weakened member of the species.
