On March 15, 2022, a young male Amur tiger named Wandashan No.1 ambushed and killed an adult male wild boar weighing more than 150 kgs (331 pounds), which is half the weight of a really big Russian wild-boar hog.

Feeding Associations between the Asiatic Black Bear (Ursus thibetanus) and the Wild Boar (Sus scrofa) in the Sikhote-Alin Mountains [2018] agris.fao.org/agris-search/search.do?recordID=US201900178364 Journal Article Feeding Associations between the Asiatic Black Bear (Ursus thibetanus) and the Wild Boar (Sus scrofa) in the Sikhote-Alin Mountains [2018] Kolchin, S. A.; We observed 12 episodes when wild boars (single animals and groups) fed on oak acorns and pine nuts which were falling down from trees where Asiatic black bears of different sexes and ages were feeding at the same time. While searching for acorns and nuts, wild boars oriented by acoustic and olfactory signals produced by bears. Adult bears practically did not react to the presence of wild boars. Bear cubs, showing anxiety, remained in the trees until the boars departed. Unilateral commensalism and indirect competition are the specific forms of interactions between the Asiatic black bear and the wild boar during certain periods of the year.

en.wikipedia.org/wiki/Dietary_biology_of_the_brown_bear One study from the Amur territory of Russia found that brown bears were actually more prolific killers of wild boars than both tigers and gray wolves, but these results are probably biased due to the scarcity of tigers in the region because of overhunting of the big cat.

Any actual confirmed kills on large healthy adults in their predator smashing prime? I'd wager it's nearly impossible for a bear to kill a large male healthy russian boar. That goes against all the principles of healthy coexistence considering boars even exist in Russia. I think a bear would kill boars more often even if they were equal in population, but not healthy ones. Tigers would take larger boars, a tiger will not stand around observing a herd of boars like a bear. So it's more limited. Bears being smart and enjoying their free trial of life wouldn't attack a healthy (!!!) large male boar because it doesn't have the ability of ambush.

It sounds like the scientists who say a striped hyena can kill any dog with a single snap, are we supposed to believe that? Evidence plz? Also predators pretty much specialize in small or compromised targets (especially opportunists!!!), it's reasonable to believe that 99% of large adult male boars are compromised individuals. If bears could waltz up to adult male boars and kill them without injury boars would go extinct. It's like me beating Mike Tyson to death and everyone goes ''Ooooh epic! Broken pelvis? What broken pelvis?'' I've heard testimonies of people being surprised how well bears can hide being so big, but even if the bear did, based on what I've seen all it can do is gnaw on the boar's back. Then you have a fight on your hands. Then the bear runs away. Reply #162 is quite expected, neither have an inclination to fight. Boars persecute cubs which is why they were hiding in trees. By the way is bumping old threads allowed?

Brown bears are not full-time predators. Only during certain times of the year, when their vegetation and other foodstuffs are less available, do brown bears spend their days hunting. When they do, wild boar is their choice prey, along with red deer. He will go after the easiest catch, regardless of age, size, or sex. Also; I seriously doubt that a tiger will ambush a huge boar of 700 to 800 pounds. But that is simply my thoughts; maybe they do.

Brown bear predation of wild boar (Russia) by Grrraaahhh. I remember Grrraaahhh saying that this is a young-adult Ussuri brown bear with a full-grown wild boar. It would have been better without the Russian red-necks. In typical brown bear fashion, the bear has already completely exhausted the wild boar.

Also; I seriously doubt that a tiger will ambush a huge boar of 700 to 800 pounds. But that is simply my thoughts; maybe they do. Oh, so that means the time where boars are the least healthy? Kind of supports my idea then. Boars need vegetation to live... if it's all gone they're literally scraping the ground for food. The easiest to catch happen to be the large males... large male boars have a 100% success rate considering in order to achieve large male status they need to survive bear and tiger attacks. They're the boars that get left behind when the herd scatters. Then what? Is the boar just a free kill? Are researchers releasing boars into the wild to hide the fact that they're actually extinct due to bear and tiger attacks? A tiger wouldn't try, and neither would a bear. 700-800lbs is unreasonably big, 400lbs is already a very rough size but if anyone is going to kill one it's a tiger. It's way more efficient at killing, and if you're attacking a boar, killing it quickly and controlling the fight is kind of a must have. And a bear is poor in the latter 2 categories.

The guys recording the video need to be shot but yeah that's something. However it is ''a boar'' that looks to be 200-300lbs and for some reason it's not moving. The bear is being more efficient than I thought it'd be.

The reason the boar is hardly moving is, quote, "In typical brown bear fashion, the bear has already completely exhausted the wild boar." First posted by Ursus arctos middendorffi ( the poster )... A brown bear would be much better able to gain dominant positions and exhaust the other animal over time. This is the general strategy they do when fighting each other (with the end result typically being a tired bear backing down or outright fleeing) as well as often when killing other animals; if unable to cause serious injuries they seem to simply exhaust it through grappling to the point it is no longer able to defend itself, and then slowly kill it. This can be seen in a few clips on youtube, such as "grizzly eats moose alive", "brown bear predation of wild boar (Russia)", and it looks like this was the case in "bear killing bear", a slideshow of a bear killing another one of similar size-note that it moved itself to the back of the other animal where it couldn't effectively fight back.

So a 200lbs larger bear can kill a 300lb boar. Yes I agree. A bear can do that to a considerably smaller boar, but why can't a same sized boar overpower the bear?

/\ The bear’s paws and flexible forearms enable it to grapple and control the wild boar even upclose. However, it must avoid the tusks of the suid.
I believe a similar size boar is a dangerous opponent as these tusks can cut like knives even upclose.

"In years of crop failure, brown bears are well adapted to the hunt wild boars.Bears do kill boar of all ages and classes.(Including adult and prime male wild boar)" We have records of brown bears killing full-grown prime wild boar. I have found no record of a wild boar killing a full-grown male brown bear. Also note, more adult male wild boar are killed by brown bears than by tigers; even though the tiger is a full-time predator. Also; the wild boar on that video appears to be well above the 300 pound mark.

It's way more efficient at killing, and if you're attacking a boar, killing it quickly and controlling the fight is kind of a must have. And a bear is poor in the latter 2 categories. en.wikipedia.org/wiki/Wild_boar#Description Some adult males in Ussuriland and Manchuria have been recorded to weigh 300–350 kg (660–770 lb) and measure 125 cm (49 in) in shoulder height. Adults of this size are generally immune from wolf predation. Such giants are rare in modern times, due to past overhunting preventing animals from attaining their full growth. *The tiger is better at making a quick kill in specific methods. However, the bear is better at controlling the fight. Just watch kittens at play. They play "ambush games." It's different with bear cubs. They play "wrestling games." From the time a bear is a tiny cub, they wrestle. One of the most common method of a bear defeating an opponent is to wrestle him down and use his weight to subdue his opponent and then to allow his adversary to struggle until he is completely exhausted. After that, the bear can take his time in killing his opponent. Also note, a bear is a highly intelligent animal. He will observe and size-up his adversary. He will recognize such things as tusks, antlers, and horns and avoid them. I doubt there is a wild boar too big for a 700 to 800 pound Ussuri brown bear to kill. *Also note; what a tiger kills he kills from ambush. If the boar hog is willing, the bear will go head-to-head with him.

www.jtgtravel.com/europe/russia/the-most-dangerous-animals-in-russia/ Wild Boar Hikers and hunters will argue that a wild boar is more deadly than a bear. Unlike bears, wild boars have poor eyesight and are likely to charge at humans when encountered in the forest. With a top speed of 40 km/h (25 mph), getting out of their way can be challenging! The average boar weighs around 200 kilograms (441 lbs) at a height ranging from 55 – 120 cm measured to the shoulder. Coupled with this extreme weight is the most lethal part of the boar, the tusks. They are solid and powerful, making the wild boar one of the most dangerous animals in Russia. Female boars are particularly aggressive when protecting their young. Wild boars can be found across Russia and are renowned in the Amur region for attacking vehicles. They tend to stick to swampy and marshy terrain. The boars’ diet is varied consisting of eggs, mice, lizards, worms, and even snakes.

Interaction between Brown bears Ursus arctos and Wild boars Sus scrofa at artificial feeding sites in Slovenia. October 2021 Conference: 27TH IBA VIRTUAL CONFERENCE Project: DinAlp Bear project www.researchgate.net/publication/355205258_Interaction_between_Brown_bears_Ursus_arctos_and_Wild_boars_Sus_scrofa_at_artificial_feeding_sites_in_Slovenia Interaction between Brown bears and Wild boars at artificial feeding sites in Slovenia Dejan Bordjan1, László Gál2, Klemen Jerina1 1 – Forestry department of Biotechnical faculty, University of Ljubljana, Slovenia 2 – Transylvanian Wildlife Project Brown bear and wild boar occupy similar habitats and have overlapping ecological niche in many dimensions. There is a wide overlap in their distribution as well as in their body weight, with bears being heavier on average. They are both omnivores competing for the same food sources. All this similarities create great potential for competition for food including physical interactions that are poorly studied. The goal of present study was to examine interactions between WB and BB at place with concentrated food source - artificial feeding sites. We used camera traps set at 21 artificial feeding sites that are traditionally used for bears in Slovenia. We compared hourly and monthly relative presence of both species at feeding sites. We found there was a minimal difference in their hourly presence, with WB being less common during the day and reaching peak in their numbers an hour or so later than BB. So, most of BBs were present before 23h and most of WBs were present after 21h. Monthly distribution was also similar with a bit more boars’ pictures during the winter months, most likely as a result of bear’s hibernation. Further, we studied a possible interaction on pictures and videos where both species were present. We found no active interaction but there was an obvious dominance of bears over wild boars. The latter kept their distance to bears and to feeders if bears were present. Our study shows no obvious spatial or temporal avoidance, but where both species are present BB is a dominant species.
