Grizzly Bear Fight in Yellowstone

Screenshot from YouTube Dave Angelescu

Dave Angelescu didn’t know what he’d see when he went down to the Hayden Valley in Yellowstone National Park last Saturday. All he knew is there had been a grizzly bear feeding on an elk next to the Yellowstone River for the past week. You know the one. There was a video of it taking down the elk the Friday before, and there were plenty of photos of it sitting over its kill in the following days.

Angelescu, who works for Xanterra in Gardiner, couldn’t get away from work until the weekend. Saturday was his first chance. He got to the Hayden Valley around 6:45 a.m. There were already 100 or more people there.

“It was a madhouse,” he said.

He parked north of the bear and hiked about a quarter-mile to get a good spot. A collared bear was sitting over the carcass. It has been identified as No. 881, a 17-year-old male.

That’s not the bear that originally killed the elk. It showed up and took over sometime late last week, after the original bear left. By Saturday, No. 881 had dragged the carcass uphill a bit and reburied it, hoping to conceal its scent.

A tree branch was sort of in the way for Angelescu to get good pictures, but soon that wouldn’t matter. Conflict was brewing.

Another grizzly came out of the forest and got into the water, swimming toward the elk carcass. It circled around a downed tree and toward the shore, looking to get a bite.

No. 881 wasn’t having it. It bolted down the hill once, forcing the other bear to retreat. Then the other bear made one more move toward the meat, and No. 881 bolted back down to the water.

This time, the fight was on. They clawed and bit at each other, splashing around in the river. They roared.

Ultimately, No. 881 won and resumed its spot over the carcass. After No. 881 made one more run toward the water and roared again, the other bear grabbed a scrap and retreated for good.

Angelescu got it all on video.

The action starts at around 4 minutes into the film.

“I was just at the right place at the right time,” he said.

He posted the full 10-minute clip to YouTube. As of today it has surpassed 200,000 views.

It was the second video from that spot in two weeks to circle the world and captivate Yellowstone-lovers. The first was of the initial kill, captured by a part-time Cody, Wyoming, resident early on the morning of Sept. 18, according to the Billings Gazette.

Officials believe the bear shown killing the elk was No. 791, a nine-year-old male.

The drama drew massive crowds to the north end of the Hayden Valley. Saturday afternoon, long after the fight, the crowd of bear-watchers was still huge. They stood on the edge of the road between Canyon Village and Fishing Bridge and gawked across the river at No. 881.

Traffic crawled. A park ranger urged people to keep from stopping in the road. Cars parked at steep angles in the ditch. People tiptoed along the road shoulder to get a glimpse.

Even so, Kerry Gunther, Yellowstone’s top bear biologist, said it was a fairly well-mannered bear jam.

“From all the thousands of bear jams we’ve had over the last 20 years, then parking was actually the best at that jam than I’d ever seen for a jam that large,” Gunther said.

Gunther said Wednesday that the bears had left and the carcass appeared to be completely consumed. But there were still people there hoping they’d see something.

Who can blame them? It’s not often that an elk killing or a fight between two big boars is that visible.

“It probably happens all the time far from a road and we just don’t see it,” Gunther said.

The Hayden Valley has one of the more dense grizzly populations in the park, according to Gunther. He said female and subadult bears are seen near the road more often than males, which tend to be farther off.

Trent Sizemore, a photographer and tour guide based in West Yellowstone, said shots of bears in that area are often from a much longer distance — maybe a half-mile away, not just across the river.

He made a few stops there last week to check out the scene. He caught video of one of the bears dragging the elk carcass farther into the trees and reburying it, a tactic meant to conceal the scent from other predators. But he wasn’t there for the fight.

“Something like that is pretty rare to see in the park,” Sizemore said. “... It just happened to occur in a good spot.”

The identity of the uncollared bear involved in the fight is somewhat in question. Sizemore believes it was No. 791, the original killer of the elk. Angelescu thinks it was likely a third bear.

Without a collar, it’s hard to say. Gunther said a third bear is a definite possibility. It’s not uncommon for there to be multiple bears on one carcass. His staff once documented 23 bears on a single bison carcass.

The question doesn’t diminish the rarity of what Angelescu caught on camera. He moved to Montana in December, and this was his fourth run-in with a grizzly since then.

None of the others were quite as eventful.

“That was definitely a National Geographic moment,” Angelescu said.

Grandma captures Video of bull elk's losing battle with Yellowstone Grizzly
For the second time this year, a visitor to Yellowstone National Park has captured astonishing video of a grizzly bear bringing down large prey.

Early on the morning of Sept. 18, part-time Cody, Wyoming, resident BE Judson shot footage of a large male grizzly pursuing a full-grown, six-point bull elk into the Yellowstone River. As the bear neared the bull, the elk turned and tried to fend off the bear by lowering its head and raking the bruin with its antlers.

The grizzly fended off the counterattack by maneuvering behind the elk’s head. It then stood upright on its hind legs and bit down on the elk’s spine. The life-and-death struggle became a battle of attrition after that, with the bear finally wearing the elk out. Both animals can tip the scales at around 600 pounds.

In the end, the bull collapsed into the water, and the grizzly methodically guided the floating carcass to the opposite side of the river, away from a gathering crowd of tourists and park officials trying to ensure everyone’s safety.

“It’s astonishing,” Judson said of the video, adding that it was such an “oh my” moment.
Known bear
Online posts have identified the bear as a known male, but Yellowstone bear biologist Kerry Gunther said the bear's ear tag couldn't be read to confirm which bear it is.

"Some people think that it may be grizzly bear #791, a 9-year-old adult male, but that is speculation," Gunther wrote in an email. "Grizzly bear #791 frequents Hayden Valley, but so do many other adult male grizzly bears."

Bear #791 was seen scavenging on a 2- to 3-year-old male grizzly near the East Entrance last October, according to the park’s 2019 bear report.

In May, Jackson, Wyoming, resident Michael Daus captured video on his cellphone of a grizzly bear using the same tactics to bring down a young bison in the Firehole River near Grand Prismatic Spring. The dead bison was removed by park staff to ensure visitor safety in the busy area, but the elk remains on the banks of the Yellowstone River in Hayden Valley where crowds of tourists have jammed the road for days to watch, shoot photos and video.

For Judson, capturing the struggle was lucky timing. She was driving down the highway between Yellowstone Lake and the Grand Canyon of the Yellowstone when she saw a herd of elk out of the corner of her eye. They were on the opposite side of the Yellowstone River.
After a Comeback, New Challenges for Yellowstone's Grizzly Bears
Fall is when elk mate. Dominant bulls round up cows for breeding. Male challengers will sometimes clash for breeding rights to the harem, which can be exhausting and sometimes deadly for the bulls if they are gored.

Gunther said grizzly bears mostly prey on elk calves in late spring and early summer. They also will bring down adult elk in early spring when bears can run them into deep snow — "bears have large feet and can sometimes run on top of the snow while elk break through the crust and sink deep allowing the bears to catch them. In addition, we see some predation on bull elk in the fall. The bulls are preoccupied with gathering and herding harems of cows which makes them more vulnerable to bear predation. Biting and separating the spinal column is a common technique we see when bears kill adult elk and bison."

Judson pulled over to take a photo but soon realized it was still too dark. Flipping her camera to video mode, she saw the bull run into the water with the big bear hot on its heels. She estimated she was only 150 to 200 yards away when the watery brawl began.

Later, when she looked at the time stamp on her footage, she found out the fight, and then the bear’s struggle to beach the bull, took almost half an hour.

“It was a long struggle,” she said.
Navigation
After the elk died, the carcass began floating toward the side of the river where the highway runs, Judson said. Possibly realizing that could jeopardize his ability to dine on the kill, the bear began guiding the floating elk to the opposite side of the river. About 200 yards downstream from where they’d both entered the water, the bear pulled most of the elk ashore, she said.

Since then, photos on social media of the bear show it burying the elk carcass, sleeping atop the pile and confronting a wolf that came to investigate.

Wildlife photographer Deby Dixon posted a photo online of the bear appearing to snarl at the gaggle of tourists across the river. She wrote that the bear is “very methodical about eating his meals,” delicately clearing dirt off the carcass before mealtime “almost like he is taking a brush and sweeping the elk clean.” After a snack, the grizzly re-buries its kill in a “thoughtful and deliberate” manner.
Bear central
“YNP has become the primary grizzly bear viewing destination in the lower 48 states,” the park said in its 2019 bear report. “The most formidable challenge for managing roadside bear viewing in YNP is not managing the bears, but sustaining and expanding as necessary the people management programs that have made bear management successful to date.”

Thanks to the park officials’ efforts to keep bears from associating humans with food, most of Yellowstone’s more than 700 grizzly bears die of old age or other natural causes rather than by human actions, the report noted.

Part of keeping humans and bears apart includes removing carcasses near occupied areas. In 2019 the park reported the removal of “101 large mammal carcasses from visitor use areas so they would not attract grizzly bears.” Another 33 times, grizzlies were hazed from high-use areas. Emphasizing how common it is to see bears in the park, officials recorded 226 grizzly bear jams in 2019 and 738 for black bears.

One other statistic that seems pertinent to the two sightings of grizzlies bringing down large prey animals this year is that there were 109 sightings of grizzlies feeding on bison and elk carcasses in 2019. That was considerably higher than the 76 sightings in 2018. Seventy-six sightings a year is also the long-term average since 1983.
In May of this year, Yellowstone photographer Jim Peaco captured images of a large grizzly feeding on a bison submerged in water in the Lamar Valley.
Grandma

Judson is a bit embarrassed and overwhelmed by all of the attention her video has attracted since it was posted. A week after the incident her YouTube video had garnered more than 800,000 views.

“I’ve already had requests from overseas,” she said.

The night before seeing the grizzly bring down the elk, she captured footage of wolves feeding on a carcass. So her summer in the park ended with some unusual experiences.

Judson created the YouTube channel so her grandchildren could see the wildlife and landscapes she experiences during her summer forays into Yellowstone.

“It’s their way to see what grandma is up to,” she said.
