Here is the rest: Black bears also demonstrate predatory behavior and have been found to be significant predators of moose calves ( Franzmann et al . 1980 ) . Here is the full source: ibb.co/bzYtZ7p

Yearling female:"The bison, judging by its body size and slender horns, is likely a yearling female, and it’s highly unusual that bison of its age and gender is alone."

I see, and it is far more recent, you know what the big difference is though? The the chart i showed you has the most important thing that a weight chart has to have, which is weight classes, your source just says "males" , they could have included subadults for all we know, but most likely they included 5+ year olds which are adults yet not fully grown, this is what usually happens when experts give average weights. So we really dont know if those are all full grown males, i would be surprised if the average went down that low.
That is correct.
That's right.
There are some posted in this thread:
A BISON DESTROYS A BEAR IN A FIGHT. THE BEAR HAD TWO HOLES IN IT. ALL THE BEAR’S RIBS ON ONE SIDE WERE BROKEN.

Of course, there are also several of bears killing bisons, including bulls, but not many, the bulls were most likely at its weakest, except 1 who was healthy. i just went thru the whole "brown bear predation" thread and counted 4/5 accounts of bears killing bull bisons, still a very rare event. I believe European brown bears kill more European bison, but then again its not as formidable as American bison.
Yes, it was posted somewhere.
When you read that a bear (or any other carnivore) killed a bull bison or any other bovid with "one blow", than you doubt it, no animal can kill a bull bison with one blow, you can best believe that. Kill yes, but not with one blow.
Same thing again, show me a video of a bear killing any animal with "one shot", it doesn't happen not even against smaller and weaker animals like wolves.
When i first started debating i used to believe those 15 accounts of bears killing bull moose with "one blow", then i realized that's not possible.

Both bear and bull ages sound estimates/guesses. Either way, they’re both inexperienced.
Yeah, you’re right. That’s why I think the average should be higher.
I took a closer look, it also says “strength is 2.5-3 greater than a humans”. And their claw length is “2 inches”.
This source may not be reliable.
Yeah; taipan posted a lot on Carnivora. There’s a handful of both sides.
It may be exaggerated, but still a kill, yes.
Wether the account is exaggerated or not, it’s true. The bear defeated the bison before it was taken down.
This is clogging up the thread so let’s just end it here.

You original question was Kodiak bear vs Wood bison bull, we cant really use predation to know who would win more because most times we dont know the circumstances of the event, bison could had been sick or weak, or the kill could had even been by ambush, like for example here:

Of course there should be more accounts of bears killing bisons (all sex and ages), than bisons killing bears as the bear is the predator.
Anyhow, I prefer to use each animal's morphological advantages/disadvantages to decide my winner, between two healthy, prime specimens.
I agree.

/\ Ouch! A kick from a much larger animal can cause some serious injury potentially.

/\ Ouch! A kick from a much larger animal can cause some serious injury potentially. That's what that wolf gets for attacking the historic bovid.

In general, the bison has no reason to fear any of the other animals that frequent the regions it inhabits, for if an individual should be attacked, the bulls rally to its assistance, and compel the assailant to flee before the blows which they inflict with their armed heads.books.google.com.ar/books?id=27rl19ySZ1cC&pg=PA384&dq=In+general+

BISON IS NOT A PREY ITEM FOR COUGARS
BOOK: Yellowstone Cougars: Ecology before and during Wolf Restoration
"Although bison numbered 2000-4000 and we encountered them in low-elevation cougar habitat-such as this one pictured near the Junction of Blacktail Deer Creek and the Yellowstone River-they were not cougar prey during the pre-wolf or doing wolf studies."books.google.com.ar/books?id=hkm9DwAAQBAJ&pg=PA19&dq=Bison+(Bison+bison)+numbered+

Predator foraging response to a resurgent dangerous prey
Abstract
Prey switching occurs when a generalist predator kills disproportionately more of an abundant prey species and correspondingly spares a rarer species. Although this behaviour is a classic stabilizing mechanism in food web models, little is known about its operation in free-living systems which often include dangerous prey species that resist predation. We used long-term (1995–2015) data from a large mammal system in northern Yellowstone National Park, USA, to understand how prey preference of a wild, generalist predator (Canis lupus) responds to a shift in prey species evenness involving rising numbers of dangerous prey (Bison bison) and dropping numbers of relatively safer prey (Cervus elaphus). Contrary to the prey switching hypothesis, wolves attacked and killed disproportionately more of the rarer, but safer, species. Wolves maintained a strong preference against bison even when this species was more than twice as abundant as elk. There was also evidence that wolves were increasingly averse to hunting bison as relative bison abundance increased. Wolves seldom hunted bison because capture success was limited to a narrow set of conditions: larger packs (>11 wolves) chasing smaller herds (10–20 bison) with calves. Wolves scavenged bison carrion instead and did so more frequently as bison abundance increased. Our study demonstrates the overarching importance of prey vulnerability to understanding the prey preferences of generalist predators in ecological communities with dangerous prey. The formidable defences of such prey diminish the potential for switching and its stabilizing influence on population dynamics. In these communities, shifts from hunting to scavenging are perhaps more likely than shifts in prey preference. The assumption of switching may therefore overestimate the stability of multi-prey systems that include dangerous prey species. A lay summary is available for this article.

Wolves really hesitate to attack bisons. Even large male grizzlies rarely take them on.
