You think that's good, that same guy also has studied lynx and wolf interactions in Belarus as well.

Cold Winter time. This grizzly will not give up a feast that without could mean starvation.

So the Butte wolf pack took down the elk and the grizzky took it away?

We have a video/documentary here ( somewhere ) of a Yellowstone grizzly that did not hibernate but rather followed a wolf pack to survive the Winter months. A great documentary. Ah! Found it - Brown bear videos and documentaries - reply #2. 600 pound grizzly "teams-up" with wolf pack 14 strong.

You notice how the Wolves surround the Bear trying to get him to leave but yet never attack... That's because the first Wolf that does is a dead wolf.

This Bear has kept in touch with this rather large Wolf Pack and knows that where ever they go a meal will be there to be taken. Otherwise, I can see no reason why this Bear is not hibernating as he looks to be healthy although the video is kind of blurry.

Good read. Yes, one writer proclaimed that a big boar grizzly can displace a wolf pack of regardless of their numbers. I wonder if this would hold true with hyenas? The was this reads; "...as high density of grizzly bear population as it can handle..." gives me the uncomfortable feeling that someone is thinking about thinning the bear population by opening-up legal bear hunting again. According to Doug Peacock ( if I remember right where I read it ), this is never necessary as bears are able and will control their on population if left alone.

We have seen the historic video of the grizzly displacing 14 wolves from a kill, we have also seen the recent video posted by Tom of a grizzly that displaced about 12 wolves from a kill. But now we know another grizzly displaced 24 wolves from a kill, the most we have heard. The numbers game is not helping the wolves against bears.

There is a big difference on how the big cats and bears perceive other large predators. For the big cat, they attempt to eliminate all predator competition. A bear will take advantage of their hunting skills. Only the "Mama Bear" with cubs has any trouble.

Yep. Regardless of the size of the Wolf Pack, they seem to instinctively know to relinquish a kill to a boar Grizzly. I've yet to see a video of such a displacement by a boar Grizzly where wolves attacked. They try to harass the Bear into leaving, but that's as far as it goes.

Spanish documentary tells of how a brown bear killed and dragged a wolf away.

As often mentioned, every animal is an individual with his or her own unique traits. Uniqueness of character is magnified in bears. Remember the grizzly/wolf pals we see pictures of? Then this; different individuals.

Then this; different individuals. Yeah, and this happened in the wild. Bears dont usually kill wolves as they most often escape.

It appears that wolf packs are dominant over black bears but when the interaction is 1 vs 1 the black bear dominates.Lone Wolf, Canis lupus, Displaced from a Kill by an Adult Black Bear, Ursus americanus, in Northeastern Alberta Wolf (Canis lupus) packs are generally competitively dominant over Black Bears (Ursus americanus); however, less is known about lone Wolf-Black Bear interactions. We report an observation of a lone Wolf and an adult Black Bear at a kill made by the Wolf in northeastern Alberta. In this instance, the bear chased the Wolf from the kill site. Our observation supports the hypothesis that Wolf-Black Bear interactions may fit the pattern of asymmetrical interference competition when the interaction involves a lone Wolf rather than a pack. There is extensive literature documenting gray wolves as the dominant competitor to black bears and cougars, through both interference competition (demonstrated by usurping prey carcasses and direct mortality; Ballard et al. 2003;Kortello et al. 2007;Hebblewhite and Smith 2010;Elbroch et al. 2015b) and exploitation competition (demonstrated by prey switching and spatiotemporal shifts by the subordinate competitors; Kortello et al. 2007;Ruth and Murphy 2010;Bartnick et al. 2013;Elbroch et al. 2015b). Wolves achieve this competitive domi- nance through their social nature, as cougars and black bears are able to overpower and even kill lone wolves (Rogers and Mech 1981;Ballard et al. 2003;Jimenez et al. 2008;Fremmerlid and Latham 2009). Through their capacity to effectively kleptoparisitize cougar kills, black bears have also demonstrated their ranking as a dominant competitor to cougars and can pose significant constraints on cougar fitness ( Murphy et al. 1998;Ruth and Murphy 2010;Elbroch et al. 2015a). ... First, a sympatric predator such as an American Black Bear, a Coyote, or a Red Fox could have found the den site, destroyed it as it attempted to gain access to one or more pups that were hiding, and killed and eaten the pup that we found (i.e., interspecific predation). However, while there have been a few accounts of mature American Black Bears chasing off (or in one instance killing) lone wolves (Joslin 1966;Rogers and Mech 1981;Fremmerlid and Latham 2009), we are unaware of any instances where these species have attacked a Gray Wolf den or killed Gray Wolf pups. Furthermore, although these opportunistic predators may be capable of attacking and killing Gray Wolf pups, they have been shown to be the loser in competitive interactions with Gray Wolves, particularly in a pack (e.g., Carbyn 1982;Peterson 1995;Ballard et al. 2003). ... www.researchgate.net/publication/233398670_Lone_Wolf_Canis_lupus_Displaced_from_a_Kill_by_an_Adult_Black_Bear_Ursus_americanus_in_Northeastern_Alberta
