Its interesting that cougars will prey on elk and moose yet avoid even female black bears. It seems that it knows the difference between prey and a larger and more powerful competitor. It confirms even more why bears have a high success rate in raising cubs. Good point yes.

YUP, IT HAPPENED AGAIN. POOR COUGAR. 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. www.foxnews.com/science/utah-bear-cougar-deer-video.amp

It confirms even more why bears have a high success rate in raising cubs. I would think that any Moose that is targeted by a Cougar as prey would be calves or sub adults and not fully grown adults. Targeting an adult Moose, even a cow would be risky at best for the cautious minded Cougar IMO. A black bear (especially a female or sub adult) might be intimidated by the Cougar as he comes across as fierce, but that's generally where it ends as he hasn't the stomach to fight a Bear that is bigger than he. Here's a consensus on mortality rates of north american Bears with regards to cubs, sub adults and adults. Black Bears seem to be the leaders here. What doesn't get mentioned in the article is what percentage of cubs parish as a result of being killed/consumed by adult males, and I suppose that would difficult at best to determine. www.jstor.org/stable/40511004?seq=1#page_scan_tab_contents

Are pumas subordinate carnivores, and does it matter? “Wolves, Grizzly bears, black bears, and jaguars are dominant over pumas.”We used 64 sources to assess dominance among pumas and other apex predators, and 13 sources to assess their relationships with felid mesocarnivores. Evidence suggested that wolves, grizzly bears, black bears, and jaguars are dominant over pumas, but that pumas are dominant over coyotes and maned wolves. Evidence suggested that pumas are also dominant over all three felid mesocarnivores with which they share range. More broadly, pumas are subordinate to at least one other apex carnivore in 10,799,252 (47.5%) of their 22,735,268 km2 range across North and South America. “Grizzly bears dominated pumas in 100% of 4 sources. Black bears dominated pumas in 67% of 9 sources.”We found evidence that wolves dominated pumas in 78% (n = 18) of 23 sources, grizzly bears dominated pumas in 100% of 4 sources, black bears dominated pumas in 67% (n = 6) of 9 sources, jaguars dominated pumas in 60% (n = 15) of 25 sources, coyotes dominated pumas in 19% (n = 3) of 16 sources, and zero examples in which maned wolves dominated pumas (Table 1; Fig. 1). In contrast, we found evidence that pumas dominated wolves in 22% (n = 5) of 23 sources, black bears in 44% (n = 4) of 9 sources, coyotes in 81% (n = 13) of 16 sources, and maned wolves in 67% (n = 2) of 3 sources (Table 2; Fig. 1). We also found 10 sources that did not detect dominance in either species where jaguars and pumas were sympatric (Table 2). www.ncbi.nlm.nih.gov/pmc/articles/PMC5786880/

Cougar kills Wolf after the Wolf initially had the upper hand. Nice rare video Tom. Usually wolf packs totally dominate cougars. But one vs one is a different story. Lone wolf has no chance i guess. The cougar got revenge.

The cougar got revenge.Yeah, and in the Bitteroot Mountains, the cougars dominate over them. Pretty big exception to the relationship.

The thing is though, according to the man who shot the video is that the Wolf actually had the Cougar dead to rights but let go and when he did he signed his death warrant. The Cougar wasn't going to make the same mistake.

Email I received from Mark Elbroch Could had happened yes. But we dont know what type of bear it was or the age. He just says "bear" Most likely a subadult black bear.

Most over on the old AVA ( the elite ) figured that this confrontation was staged with tamed animals ( Hollywood ).

There are three big cats of moderate size sometimes referred to as "panther", the cougar, the leopard, and the jaguar. With both leopard and jaguar, it is normally the black version known as a "black panther".
The Bear Almanac - Second Edition:
Mountain lion - Grizzly bears steal from mountain lions, but each has a healthy respect for the other. Enos Mills wrote in The Grizzly, "Bears and lions are not neighborly, and at best each ignores the other; but one bear I knew followed a lion for weeks... profiting by food-supply- the excessive killing of the lion.

This is an account of hunters going grizzly bear hunting. When they were searching for bears, they saw a fight between a cougar an a grizzly bear. The bear won by breaking the cougar's neck with a paw strike. The bear missed it a few times but it got it.

A FIERCE ENCOUNTER.
(PECK'S BTTN.) I had made a business visit to Gardiner, a small town lying on the northern boundary of the Yellowstone National Park, and having oompleted tho business that called me thence, was seated one cold wiuter evening in the hote^ office, where a number of old-timer mountaineers were relating 1 adventures of early days, when one of them related the following story of a fight witnessed by him between a panther and grizzly bear in tho Teton mountains in Wyoming. I give tho yarn below, Just as he told it, in tho dialect language of the mountaineer. 'Twas in the 'arly 70's," began the speaker, as he bit off a huge mouthful of plug tobacco and commenced masticating tho same with great vigour, "that I seed tho darn'd'st fight you ever hearn tell of, over in the Tetona. 'Twos between an old grizzly and a painter, and the way they fit wuz a caution to snakes. I hed bin out in tho Big Horn kentry guidin* a party o' tenderfeet sports frum N'York, but game wuz purty scarce in thot section thot fall, so ono day wo pulled stakes and lit out fur the- Tetons. I toll ye there wuz lots o' game thar, and deer and elk wore bo plentiful that the tendorfeot couldn't help but kill suthin' ono't. in a while. They continued thla kind 'o sport until they got sort o> tired of it and began ter look round far Var. Their main ambition seemed tor be ter get a swipe at a grizzly, and they wuz keen fur a bar hunt so one day I sez to 'em Boys, how'd ye like ter take a trip overi to "Wildcat canyon and kill a bar or two "•Goodi first-rate 1 bully J 1 they all cried, and so next morni*' we lit out. 'T was twolve or fo'teen miles to tho canyon, but I kuowed bar was plenty thar, and we'd stand a sight botter show tor kill 'em thar than auywhar else in the mountains. "We arrived at tho canyon all right and hunted round, but didn't see anythin' o' b'av thet day, bo tow'rd evenin' I shot a deer and we pitched camp on the creek. We used part of the deer fur supper, and tho balanco wo hung to a limb o' a tree only a few rods from camp. Wall, that night, 'twas about two o'clock, I guess, wo wus all 'wakened by the durndest howlin' and screechin' you ever hearn tell of. "We all jumped up, and what do you think we seo'd? Why, right thar under tho tree whar the deer wuz hangin' was a monster grizzy bar and a painter, and they wuz fightin' ter beat thunder. The bar would grab the paiuter and give him an awful hug, but tho cat would slip out o' hia clutches, ho wuz so nimble, and would make thet old bars hair fly fur some time. We watched thet fight with interest, I kin tell you, but the animiles never seemed to notice us, fur they kept right at it, and the way the painter would tear flesh and the way the grizzly would thump tho cat round beat anythin'. Howsomever, it hed to como to an end somo time, and when they hed boon at it about half an hour, we noticed that the cat wuz beginnin' to git somewhat the worst of tho fight. Old grizzly wuz pretty well winded, too, and seemed to' want to end tho fight purty quick, fur he wuz filuggin' the painter over tho head in great iihape with his paw. Finally he guv her ouo awful welt and she foil over plump dead, with her neck broken. We then opened fire on tlio grizzly, and brought him to the ground with a few shots. When wo examined him, we found that the flesh along one side o' the ncok and on tho left shoulder wuz all tore off by the painter's claws, and ho wuz other wiso badly done up but his great strength had kept him up until he had conquered his enemy. AVhen wo Bkinned the cat wo found thet half the bones of her body had bin broken by the huggin' sho received. Thet wuz an awful fight, boys, and I never 'xpect to see another like it, fur it is not often $iat a paintnr will get up dander enough to fight, loastwiso with a grizzly bar." Yes, thet's so!" assented the others. Aud then at my simple invitation to take something, they ranged alongside the bar, and with surprising unanimity of sentiment called for corpse reviver straight," and we all drank to the health of the story toller.

Bears by Richard Perry:
In ( North ) America a few black bears are killed by pumas. Although averaging not much more than one hundred fifty pounds in weight, a puma is such an agile carnivore that it can compete on equal terms with the much more massive jaguar; but one would not expect it to threaten a grizzly weighing up to nine times its own weight, and accounts by the old mountain hunters of the American West indicate that most pumas, though bristling and growling, would edge off the trail and give the disinterested grizzly the right of way. Similarly, when feeding on its kill, a puma, though snarling and spitting in the most threatening manner and holding its place until a grizzly was within a few feet, would ultimately surrender the kill. It would strike at the bear as it dashed off, but the latter would not even bother to take notice of its going. Nevertheless, an occasional grizzly is shot with long, deep scars on its back; and the fact that a medium-sized one may s ometimes be killed by a puma is indicated by the account of an Army officer hunting with two Apaches on the Pecos during the last century. According to Seton, they had tracked a large puma to a canyon, where their attention was attracted by a fearful din:
A middle-sized brown bear was standing on his hind-legs with his back against a big rock and was yelling bloody murder. The lion was crouched on the ground about twelve or fifteen feet from the bear. They waited there quite a while, the lion in the position of a cat about to spring, working his tail, with his ears laid back and getting ready for a jump as he moved his feet back and forward, as you will see a tomcat do. Once in a while he would growl. At last the lion charged the bear and grabbed him, and they both went down together and the dust flew up so that it almost hid the two fighters. In a little while the lion suddenly let go and sprang back to where he had been before. Both animals were bleeding and each was licking its wounds. The bear kept up his moaning and screaming and would have been mighty glad to get away, but he did not dare to expose his back to the lion. At last the lion charged the bear again, and this time with his claws he tore open the bear's back, and his claws must have reached some deadly part, for the bear fell over dead and the lion went off to his old place and began to lick his wounds again. After a while he took hold of the bear's carcass, and began to drag it down the hill and cover it up with leaves and brush.
*A middle-sized brown bear = an adolescent grizzly bear.

It is in the nature of a bear to displace other predator species from a carcass. Plain and simple truth. shaggygod.proboards.com/

While these kill sites attracted other species, most of the kills were protected due to burial or hidden underneath trees. Roughly 64% of carcasses were found under a tree or thick brush, while the rest were buried in the dirt or under grass. The mountain lion made an attempt to cover all carcasses, but several scavengers came to investigate or eat part of the carcass. The most common visitor was the turkey vulture, followed by other bird species, then coyotes and small rodents. One carcass was visited and consumed by a black bear, which resulted in the mountain lion leaving the kill and the general area for a few weeks. The presence of a black bear visiting the mountain lion kill may have forced her to make additional kills rather than to compete with the larger predator, especially since she had two vulnerable kittens. These dynamics may shift prey choice and predation strategies, but more data would be needed to tease apart those interactions. shaggygod.proboards.com/

Abstract: Pumas (Puma concolor) and black bears (Ursus americanus) are large carnivores that may influence scavenger population dynamics. We used motion-triggered video cameras deployed at deer carcasses to determine how pumas and black bears affected three aspects of carrion acquisition by scavengers: presence, total feeding time, and mean feeding-bout duration. We found that pumas were unable to limit acquisition of carrion by large carnivores but did limit aspects of carrion acquisition by both birds and mesocarnivores. Through their suppression of mesocarnivores and birds, pumas apparently initiated a cascading pattern and increased carrion acquisition by small carnivores. In contrast, black bears monopolized carrion resources and generally had larger limiting effects on carrion acquisition by all scavengers. Black bears also limited puma feeding behaviors at puma kills, which may require pumas to compensate for energetic losses through increasing their kill rates of ungulates. Our results suggest that pumas provide carrion and selectively influence species acquiring carrion, while black bears limit carrion availability to all other scavengers. These results suggest that the effects of large carnivores on scavengers depend on attributes of both carnivores and scavengers (including size) and that competition for carcasses may result in intraguild predation as well as mesocarnivore release. shaggygod.proboards.com/
