This is a sad incident. The two species should not have been confined together - bad management. In the wild, this would not have happened.

In the wild, this would not have happened. yeah you said the same thing for the news of the bear that decapitated the wolf, and also the bear who killed a polar wolf. Its really dumb to put them together....result...dead wolves. by the way, its really rare to see brown bears attacking together like that, maybe they were family who knows, also those bears looked very small, like young subadults right.

Right. Juvenile sub-adults normally hang-out together for some time ( in the wild ) - usually siblings.

Imagine if adult brown bears would run in bear prides like that in the wild? It would be hell for the other animals, ha ha ha. I mean just a brown bear alone is already hell.

www.lakeforest.edu/live/news/5515-impact-of-wolf-reintroduction-on-bison-and-grizzly?preview=1 Conclusion Overall, the reintroduction of wolves into Yellowstone National Park has had a variety of direct and indirect effects on the bison and grizzly bear populations. The increased wolf population has been able to reduce the numbers of elk present in the park, allowing for an increased food supply for both the grizzly bear and the bison through the effects of the trophic cascade. While this has allowed for growth of both the grizzly bear and bison populations which, would appear to be beneficial for conservation, there are actually a number of other factors that do not allow for the benefit to be as impactful as would be desired. It has been shown that the growth of the populations has resulted in a very high density of individuals in both species, making it difficult for each species to continue living in its original territory. This, plus a number of human factors including habitat degradation and construction, has caused negative effects for both species. While the intentions of reintroducing the wolf back into Yellowstone National Park may have been good, there were several factors that were not taken into account, reducing the effectiveness of the measure.

www.nps.gov/yell/learn/nature/bearwolves.htm In summary, a restored gray wolf population in YNP would probably have little, if any, effect on the grizzly bear and black bear populations and vice-versa. With the exception of encounters near carcasses and wolf dens, most bear-wolf interactions could be classified as non-confrontational with no injuries occurring to either species involved. Observations to date suggest bears may actually be benefitting from the presence of wolves by usurping wolf-kills.

What were these "professionals" thinking by placing wolves and bears together within a confined space? Ridiculous.

In reality, it was pack vs pack. Its just that the other wolves were scared to get involved.

In reality, it was pack vs pack. Its just that the other wolves were scared to get involved. Adult brown bears are not normally this social. IMO - this is either sub-adult siblings or a mother with three nearly-grown cubs. Siblings is possible although four cubs is uncommon.

Here is a video of 2 grizzlies vs 7 wolves at Yellowstone.

Wolves chased the bear. Wolves are a very formidable foe for bears. Wolves have numbers.

Great find Kodiak. Those bears in the first video destroyed that wolf.

By Wolverine - wildfact.com/forum/ Reason for scavenging of wolf kills by brown bears which probably could be applied for the brown bears and tigers as well: "Additionally, grizzly bears now take advantage of the predatory behavior of wolves by waiting for the wolves to finish hunting and then contesting the wolves for access to the carcasses of their kill (Smith et al., 2003). As a result of being the larger animal in these standoffs, bears usually win, giving them access to food without the work involved in actually tracking down and killing the prey themselves (Smith et al., 2003). In addition to the obvious benefit of being able to consume this food, the grizzly bear populations do not have to expend the energy to hunt, as they now have a species that virtually does the hunting for them (Smith et al., 2003)." www.lakeforest.edu/live/news/551...?preview=1

From above link.
... Grizzly bears prey on elk calves during late May through early July (Gunther and Renkin 1990, Fortin et al. 2013) and to a lesser extent on older elk throughout the year (Mattson 1997). Bears opportunistically use carcasses throughout the active season and, since reintroduction of gray wolves (Canis lupus), usurp wolf kills (MacNulty et al. 2001, Ballard et al. 2003, Gunther and Smith 2004). Yellowstone grizzly bears have been identified as one of the most carnivorous interior populations in North America (Jacoby et al. 1999, Mowat and Heard 2006). ...

Notice observation #3, adult female bear with 2 cubs vs 4 adult wolves with 2 yearlings, the bear was the dominant species.

I would suppose that when there is a dispute over a carcass, the "Dominant species" is the one who gets the carcass. As for "Rendezvous" I suppose who retreats from who. A she-bear will always try to keep her cubs away from danger.

Looks pretty even with the adult female bears. But the adult male bears should totally dominate the kill sites.

Looks pretty even with the adult female bears. But the adult male bears totally dominate the kill sites. Only a mother with cubs. Her concern is her cubs. If she is fighting one or two wolves, then the other wolves kill the cubs. So, in trying to keep them close to her and escape the wolf pack, she might appear to be submissive. Without cubs, the wolves are unlikely to try her.

Absolutely right Brobear, and that is exacly why wolves, even 14 strong dont try it with adult male bears as we have seen.
the female bears mostly do a great job protecting the cubs, even from 4 or 5 wolves.
