Grizzly Bears view cougars as "Feline Gravy Train"
"Cougars, however, generally give the bears a wide berth. Grizzlies have less competition with cougars than with other predators such as coyotes, wolves, and other bears. When a grizzly descends on a cougar feeding on its kill, the cougar usually gives way to the bear. When a cougar does stand its ground, the cougar will use its superior agility and its claws to harass the bear yet stay out of its reach until one of them gives up, usually the cat."
Though grizzlies likely kill few cougars, they may see the cats as a feline gravy train. Between 1990 and 1995, wildlife biologist Kerry Murphy and other HWI researchers monitored 113 cougar kills (mostly deer and elk) in Glacier and Yellowstone and discovered that bears (grizzlies and blacks) were claiming a significant share of the spoils. Bruins visited about one of every four cougar kills, robbing the feline owner of as much as 26 percent of its food requirement, sometimes for several days running. "It appears," says Murphy, "that competition for kills creates significant gains for bears and significant losses for cougars."

Bear Saves Robert Biggs From Mountain Lion Attack In California

Updated Dec 06, 2017
When Robert Biggs finished gazing at a cute, cuddly family of black bears and turned to continue on his day-hike in northern California on Monday, he thought he was safe.
The 69-year-old man from the town of Paradise was anything but.

He’d been watching a mother bear, her yearling and a newborn from about 40 feet away, but he had no idea that he was being stalked by a ferocious mountain lion. As he turned to leave, the cat pounced on his backpack with all four paws.
See the photo below
“He grabbed me from behind and knocked me to the ground,” Biggs told The Huffington Post. “I was on my knees. I had my rock pick out because i was on a steep incline, and I smashed the cat in the head with it. He screamed, but he didn’t let go.”
His backpack and rock pick were the only things standing between him and certain death, Biggs said. He raised his weapon again for another swing at the hulking feline.
“That’s when a blur on my left side grabbed the lion by its throat — turns out it was the momma bear,” he said. “I heard a tremendous screeching, some growling noises.”
Biggs said that the bear ripped the cat’s grip from his backpack, and the two titans clashed for another 15 seconds. The bear won the battle, probably because it “outweighed the cat 400 pounds to 100 pounds.” The cat ran away, and the bear went back down on all fours, humbly making eye contact with Biggs before regrouping with her young.
Biggs — who had been hiking the same two-mile trail in the Bean Soup Flat area for years — left with a few scratches and bruises on his arm. Being a mountain man, he refused his wife’s pleas that he go to the hospital, and instead put some peroxide on his wounds.
He told The Huffington Post that he owes everything to that bear.
“I’m 100-percent sure it did want to save my life,” he said. “We made eye contact. I’d seen the bears before and I know she knew who I was.”

COUGAR KILLS IN YELLOWSTONE NATIONAL PARK IN 3 DIFFERENT TIME PERIODS. (17 YEARS STUDIED), NO BEARS KILLED.

Utah bear steals and eats cougar’s kill, video shows
First come, first serve.
A bear in Utah was caught on video stealing the deer a cougar had killed and hidden away in an attempt to save for another time, wildlife officials said.
The Utah Division of Wildlife Resources tweeted that they recorded the footage as a way to study interactions between cougars and other animals at kill sites.
“When a collared cougar is detected occupying an area over several hours, we visit the site to determine if the cougar has made a kill, and we set up a camera on the carcass,” the agency said.
Captions on the video explain how the collared cougar returned to feed on the recent kill it stashed away. The cougar hid the deer carcass again, but the following night a black bear arrived on the scene.
The bear dragged the carcass out of the cougar’s hiding place and fed on it for about two hours, the agency said. The cougar returned a few hours later, inspected the area and appeared to leave – just before the bear came back to the scene.
It wasn’t immediately clear if the animals had direct contact with one another. The agency said the cougar likely had to give up its kill to the bear.

ENCOUNTER COMPETITION BETWEEN BEARS AND COUGARS:
SOME ECOLOGICAL IMPLICATIONS
GREGORY S. FELZIEN,' Hornocker Wildlife Institute, 3246, University Station, Moscow, ID 83843, WA, USA
Abstract: Black bears (Ursus americanus) or grizzly bears (Ursus arctos) visited 8 of 55 cougar-killed (Felis concolor) ungulates in Glacier National Park (GNP), Montana, from 1992 to 1995, and 19 of 58 cougar kills in Yellowstone National Park (YNP), Wyoming, from 1990 to 1995. Bears displaced cougars from 4 of 8 carcasses they visited in GNP and 7 of 19 in YNP. Cougar predation provided an average of 1.9 kg/day (range = 0-6.8 kg/day) of biomass to bears that fed on cougar-killed ungulates. This biomass was an important percent (up to 113%) of the daily energy needs of bears when compared to their caloric requirements reported in the literature. We suggest that ungulate carrion resulting from cougar predation is important nutritionally to bears in some regions and seasons. Cougars that were displaced from their kills by bears lost an average of 0.64 kg/day of ungulatebiomass,or 17-26% of their daily energy requirements. Biologists modelling or measuring cougar predation rates should be aware that losses to scavengers may be significant.

REPLY #12:
So, the great thing about this report is the clear separation beween bears just "visiting" cougar kills and bears "displacing" cougar kills. From the abstract and chart:
GLACIER NATIONAL PARK-(1992-1995, 55 TOTAL KILLS), 4 DISPLACEMENTS OUT OF 8 VISITS= 50% DISPLACEMENTS.
YELLOWSTONE NATIONAL PARK-(1990-1995, 58 TOTAL KILLS), 7 DISPLACEMENTS OUT OF 19 VISITS= 36.84% DISPLACEMENTS.

Nice thread, I'm @kesagake. But I think you should put much more information because I found an interesting article about Warren B Ballard, one of the most important authority in National Park Service saying that most interactions between cougars and bears are anedoctal,I don't know if you ever saw it but I think it should be interesting because I think it refutes cougars killing bears accounts too.  www.researchgate.net/publication/275651420_Wolf_interactions_with_non-prey |

Mountain lions often lose to wolves and bears, study finds.
That chart actually came from Panthera. So this is a valid source.  |
