Yeah but there they only talk about one black bear. But guess what it also says? By ambush, how else would it win? Irrelevant. So until “El jefe” (the boss) beats a bear in a face to face battle, its more like “the oportunistic backstaber” lmao. “In the Smithsonian article, Bugbee speculates El Jefe could have taken down the black bear by ambushing the unsuspecting animal as it foraged”.

Exactly. Another bear by ambush. And it was a sow black bear too. We all know sows don't get very big at all. Not like the males do.

shaggygod.proboards.com/ Both grizzly and black bears live in Yellowstone National Park. In this and other areas where grizzly bears and black bears are sympatric (share habitat), temporal isolation and behavioral differences tend to reduce direct competition between the two species. In the Greater Yellowstone Ecosystem, grizzly bears are generally most active from dusk until dawn, while black bears are most active during the daytime. Grizzly bears evolved to forage in open meadow habitats, whereas black bears are primarily adapted to living in forests. Grizzlies also have longer claws and larger shoulder musculature than black bears, making them more efficient at foraging roots and ground-dwelling small mammals abundant in open meadows. Grizzlies are generally larger than black bears, and are much more aggressive in defending themselves and their offspring from predators, including other grizzlies. Black bears typically escape predators by running into forest cover or climbing trees. On August 2, 1998, park visitors looking for grizzly bears from Grizzly Overlook in Hayden Valley observed some ravens on a carcass on the northeast side of the Yellowstone River. Upon focusing their spotting scope on the carcass, they could clearly see the partially consumed remains of a black bear in the tall grass next to the river. The visitors reported the presence of the carcass to Canyon area rangers, who immediately forwarded the report to the park’s Bear Management Office. We received permission from the rangers to canoe across the Yellowstone River to examine and retrieve the carcass.

December 27, 1997 Missoulian Article By Sherry Delvin: Black bear mauled by grizzly. Attack on hibernating bear is first ever, says Diane Boyd-Heger, wolf researcher.
A grizzly bear apparently looking for one last load of calories before winter's respite, excavated and ate an early denning black bear in the remote North Fork last month.
The incident, documented by wolf researcher Diane Boyd Heger and her husband Ed, is the first record of a grizzly bear hunting and killing a hibernating black bear.
The story of its discovery is a lesson in bear behavior and human misbehavior. the couple said Friday. It goes like this:
On an ordinary overcast, snow-encrusted day in November, Ed Heger took his dog for a walk out behind his cabin, in the North Fork of the Flathead, on the edge of Glacier National Park in far northwestern Montana.
As it often does, Heger's path passed an oversized slash pile, a 35-by-35-foot monstrosity abandoned two decades ago and loaded with dirt and trees and logs. At the edge of the pile, he saw blood on the snow and a drag trail. CAG Comments Two decades ago people were in the area trying to eck out a living by cutting timber, posts, poles or whatever. Over the score of years bears have made use of the pile for denning purposes. This further demonstrates that bears do not avoid humans activities in their habitat. End CAG Comments
He suspected hunters and a deer kill at first, but realized a short way down the trail that there were no human footprints in the snow. And that there were grizzly tracks.
Heger and his dog, Beamer, followed the path 50, maybe 60 yards, Heger reaching for his bear spray and lifting off the safety. Beamer nervously watched a stand of lodgepole up ahead.
"She's a border collie and she's very bear smart," Heger said Friday. "She'll let you know there's a bear in the area."
Which was just about when Heger heard branches breaking "Beamer gave a little woof and turned tail. Heger saw the grizzly charging out of the trees.
"The speed at which that bear came out of the woods was unbelievable," he said. "There wasn't time to get scared. It was all just happening."
Heger fired his bear spray in the air and it hung in a big cloud. The grizzly hit the spray about 15 feet from Heger and veered away, never slowing.
"And Ed got the hell out of there," said Boyd-Heger. "The dog was already gone."
A few days later, Heger loaded Beamer into his pickup and drove to the slash pile. But when he rolled down the window, Beamer went into her bear alert and I knew the grizzly was still around, so we left right away."
"I felt bad already," Heger said. "Here was a bear doing what it was supposed to be doing, and here I was invading its territory, doing what I wasn't supposed to be doing.." Not until two weeks later did Heger returned to the slash pile with his wildlife biologist-wife - each with a can of bear spray, and the dog alongside. That's when they discovered the unusual nature of what Heger had happened upon.
The grizzly had, not long before Heger's arrival, discovered a black bear's den below the old slash pile. Opting not to use the entrance and tunnel already dug by the black bear, the grizzly tore through the top of the den and dragged out its prey.
"I imagine the denning bear was somewhat lethargic," Boyd-Heger said, and surprised. The grizzly dragged the black bear, which Heger believes was a fairly small animal he had seen a month or so earlier near the slash pile, into the lodgepole pines - very near to where Heger was charged.
"Ed didn't know it when he started following the drag trail, but the grizzly bear was right there on a fresh kill," Boyd-Heger said.
"The bear's reaction was very normal and completely justified. Ed was in his territory." Boyd-Heger said the grizzly ate the black bear "to the toenails. There were only a few bone splinters left. And there weren't really any signs of scavengers. The grizzly sat there and ate it all."
There was but one end of a femur to take to the animal museum at the University of Montana for comparison purposes. But from what she saw, Boyd-Heger said, the black bear was fairly small.
And the grizzly, based on its 9-inch-long toe-to-heel hind footprint, was about 250 to 300 pounds either an adult female or a subadult male.
Boyd-Heger said she called "all the bear people I know," asking. if anyone had ever heard of a grizzly bear excavating and consuming a den fling black bear.
They had not.
She found articles on black bears killing black bears and on grizzlies killing grizzlies - and on grizzlies killing black bears encountered by chance ("say, they were feeding on the same huckleberry patch.")
But no one had heard of or recorded an in-the-den attack; thus, Boyd-Heger's plans to publish "a little note" about the North Fork incident as a scientific paper.
"My over-Christmas project," she said.
Boyd-Heger has spent the past 18 years in the North Fork, on the edge of Glacier National Park, studying wolves and, less so, coyotes - "and inadvertently mountain lions and bears."
Black bears, she said, tend to den about a month earlier than the larger grizzlies, who spend the extra time loading up on calories for the long winter.
Most grizzlies den and hibernate when the snow gets deep enough to hinder hunting, but some North Fork animals stay out for part of the winter, she said. "Because we've got wolves and lions in the area, there's a Carrion resource all winter. The grizzlies take advantage of that."
Boyd-Heger and her husband emphasized, though, that he should not have followed the drag trail into the woods when he saw the bear tracks. And that the pepper spray was his salvation. "I would really emphasize that I was doing something I shouldn't have been doing," Heger said. "But you know how human nature and curiosity are."
"Luckily, the bear spray worked exactly as it should have," Boyd-Heger said. "It was a very successful deterrent, better than a handgun by far. It saved my husband and the bear, most likely." And the story. bitterroot.com/grizzly/BEARS11.HTM

From Grrraaahhh... Because both brown and grizzly bear kill black bear my position was the question to be immaterial. Also, as you know, in the Russian Far East; the brown bear will kill/cannibalize Asiatic black bear.

The recent killing of a black bear cub by Grouse Mountain's resident grizzlies was an example of nature taking its course, according to a representative for the resort. The incident, which took place Oct. 2 but which was not made widely public, was unfortunate, said a spokeswoman, but was ultimately a reality of bear behaviour. "(The grizzlies) behave how that they would in nature," said Sarah Lusk, a spokeswoman for Grouse. "This is the first incident the bears have had in the 10 years that they've been here with a black bear." The roughly nine-month old cub worked its way under the fence that contains the mountain's two rescued grizzlies, Grinder and Coola, at about 5: 30 p.m. Oct. 2. A small number of visitors watched helplessly as the resident bears attacked the intruder and killed it. Resort employees were unable to intervene for safety reasons, said Lusk. "Our wildlife staff were immediately on the scene, but couldn't do anything to save the cub," she said. They were forced to wait until the grizzlies were in another portion of the enclosure before entering to retrieve the body. The mountain reviewed the incident, said Lusk, but ultimately concluded it didn't warrant changes to the way in which the bears are managed. Christine Miller, education co-ordinator for the North Shore Black Bear Society, was generally in agreement. "It was rather unfortunate," she said. "But I'm not out to point a finger at Grouse." That grizzlies will kill black bear cubs is an unpleasant fact of nature, said Miller. "In the wild, they certainly could eat it," she said. "(But) these guys are well fed, so it was probably more of a territorial thing; they kill things that enter their space."

‘It had been completely consumed’: Grizzly bear eats black bear in Banff Colette Derworiz, Postmedia News | 22/08/13 | A large male grizzly bear is showing everyone who’s boss in Alberta’s mountain parks. Earlier this month, officials closed the Sundance Canyon area in Banff National Park after a group of hikers came upon a bear known as No. 122 feeding on a carcass. They reopened the trail late Tuesday after he moved on. During the investigation into the incident, officials determined the carcass was a small black bear. “It had been completely consumed,” said Steve Michel, a human wildlife conflict specialist with Banff National Park. “There was nothing remaining other than a skull, a hide, the four paws and some bones.” It’s believed it was a predatory attack on the black bear. “There were indications the black bear was foraging on the trail at the time,” he said. “It looks like that black bear just happened to find himself in the wrong place at the wrong time when a very large grizzly bear came by.” Michel said he didn’t expect there was much of a fight. "I don’t think there would have been much of a brawl that took place. It would have been fairly quick." “This is grizzly bear No. 122, so he’s a very large grizzly bear,” he said, noting it’s a 225- to 275-kilogram grizzly bear killing a 45-kilogram black bear. “I don’t think there would have been much of a brawl that took place. “It would have been fairly quick.” Although it’s not a common occurrence, Michel said there are other documented cases of grizzly bears feeding on black bears — including No. 122 eating another small black bear around the same time last year. “He’s definitely the dominant animal out on the landscape, so there are very few animals that would compare against him in terms of size,” he said. Meanwhile, another closure was put in place in the Marble Canyon area in Kootenay National Park due to a large grizzly bear feeding on an elk. “We did have a situation where people inadvertently passed really close by,” said Omar McDadi, spokesman for Lake Louise, Yoho and Kootenay national parks. The closure, which will be in place until the bear finishes the carcass, includes the Marble Canyon interpretive trail and surrounding area, the Tokumm Creek trail up to Kaufmann Lake, the connector trail to the Ochre Trail junction and the Helmet/Ochre trail. It’s possible the bear is again No. 122, although McDadi said that hasn’t yet been confirmed. As a precaution, officials have evacuated 12 backcountry users from Rockwall trail by helicopter. “Their main access point is through Marble Canyon,” he said, noting people who are still on the trail are being asked not to come down through the closed area. nationalpost.com/news/canada/it-had-been-completely-consumed-grizzly-bear-eats-black-bear-in-banff

Still more from ... shaggygod.proboards.com/ "So today I had the most amazing wildlife encounter. I was driving a bus full of people on the David Thompson highway in Alberta, Canada and got stopped for an hour due to a motorcycle accident that happened when a biker stopped to see a bear on the side of the road and was hit by another biker. (a lot of road rash and maybe some broken bones but they survived). Turns out the little black bear was in the tree because a huge grizzly bear was at the bottom of the tree trying to get him (or her?). We watched the poor little black bear hang on for dear life and make a number of attempts to get away. I had to leave before the end of this encounter and I can only hope the black bear made out okay although his chances did not look good".

Nature Shock - The Bodiless Bear The fascinating documentary series examining freak occurrences in the natural world continues. This programme looks at a series of brutal attacks on black bears in Yellowstone Park, including the extraordinary case of a severed bear head. As experts examined the seemingly unrelated cases, they found evidence that the killings were the work of the black bear’s more aggressive relative, the grizzly bear. In 1990, whilst hiking through Yellowstone National Park, bear expert Dr David Mattson came across a most hideous and unbelievable sight: the severed head of a black bear. Mattson describes his grisly find as “one of the most macabre things I’ve ever seen”. The case of the bodiless bear, and three subsequent bear slayings, would go on to shed new light on what scientists understand about bears and their habitat. All the evidence indicated that the bear without a body had fallen victim to a larger, more savage predator that had killed it for food. But biologists only began to understand the case when a second black bear was found dead on an open stretch of land. This bear had been brutally attacked and its penis had been ripped off. Judging from puncture marks on the corpse, it was clear that only one predator in Yellowstone could have been responsible. “If you look at the preponderance of evidence, it leads us to conclude that he had been killed and eaten by a grizzly bear,” says biologist Dr Charles Schwartz. Grizzlies are almost twice the size of their more placid black bear cousins. They are among the most fearsome predators in North America, standing at a height of eight feet and capable of running at up to 30mph. However, whilst it was known that bears sometimes turn on their own kind, there had never been a documented case of grizzlies killing black bears in Yellowstone. The bears’ habitat provided a possible explanation. Black bears are primarily forest dwellers, whilst grizzlies rule the open spaces. However, both species sometimes overlap in the trees when foraging for food. The first killing could have been an opportunistic attack by a grizzly; the second was a clear case of a black bear straying onto grizzly territory. The third incident, however, was more surprising. A team of researchers monitoring bears tagged with radio transmitters came across the dismembered body of a black bear in the forest. Body parts were strewn about a clearing and the bear’s skin had been pulled inside out. This was the first case of a grizzly attack deep inside black bear territory. After close investigation, the team concluded that the beasts had been foraging in preparation for winter hibernation when they encountered each other. “The bear spends most of its active period in the fall searching for and consuming foods,” explains Schwartz. The grizzly was looking for fattening pine cones when it decided to feast on its opponent instead. The fourth victim was found in a scene eerily similar to the last – but with the crucial difference that it was killed at the end of winter. Grizzlies awake from hibernation before black bears, and it is believed that one such creature – driven by hunger – detected its sleeping cousin and took the opportunity to strike while it was in its den. The research team was even able to track down the grizzly responsible from a ripped-off claw that it left at the scene. These four shocking cases have provided biologists with concrete evidence of grizzly predation on black bears for the first time, and offer striking insight into the behaviour of bears. “No two bears are alike,” affirms Dr Mattson. “I’ve known some bears that I would consider to be well adjusted and... some bears that probably could be called psychotic.” The bear slayings of Yellowstone Park have helped scientists to understand more about how these remarkable creatures co-exist in the wild.

Regarding black bears, bigbons said that larger male Blackbeard at 600 pounds and above grow increasingly bold and predatory yet I wonder why they being larger than most grizzlies do not consider preying on one. Probably because the grizzly bear is way more aggressive (aggression due to being around smilodons, giant short faced bears etc)due to being not a skillful climber like the black bear.

You will find that the record-size black bears are all in the eastern-half of N. America where there are no grizzlies. However, I believe that a few hundred thousand years of co-existing with the grizzly would implant a fear into the black bear's DNA.

Yeah Ursus, not only more agressive, but stronger, better fighter, longer claws, just much meaner. That is why the grizzly totally dominates black bears in every aspect. I have seen zero reports of even the largest black bears even bothering a grizzly.

According to bigbons, black bears at 500 pounds and above become increasingly bold and carnivorous and there are black bears that can reach 600 or 700 pounds. Perhaphs there might be some unseen encounters?

Perhaphs there might be some unseen encounters? Of course there has to be some unseen encounters in the wild. But talking strictly of accounts and videos, we have not seen a single event of a black bear beating a grizzly bear. Its always the grizzly that attacks and kills the black bears and even steals their kills.

Here is a good example. “The real boss bear of these parts” a young grizzly looks like he stole something from the black bear. A cub is at the top of the tree also.

Two very interesting finds Kodiak. I will mention the black bear/alligator relationship on "Bears surviving in Africa".
