Hibernation and denning Dens are excavated by males and females as early as September or immediately before use in November. Dens in dug earth have a tunnel about 4 feet long leading to a chamber 5 feet in diameter (Murie 1981) Some dens have no entrance tunnel. (Garshelis 2009) Onset of hibernation spurred by length of day and often by a snow storm. (Servheen 1993) Rocky Mountains den sites: Have deep snow that doesn't melt in temporary winter thaws Are on steep or moderately steep slopes Females and cubs may be vulnerable to snowmobile disturbance during denning and immediately after denning. (Podruzny et al 2002) In Croatia, Dens built in rock cavities, under tree roots, in hollow trees, on the ground under conifers. (Huber & Roth 1997) In barren-ground habitats of Arctic regions: (McLoughlin 2002) Grizzlys dug dens under tall shrubs, using the roots as the den roof Bears carried nesting materials to den Females entered dens earlier than males Both sexes are denning by October Males emerge before females in late April, early May. During denning About 1/3 of females give birth Another 1/3 of denning females are still nursing yearlings (Craighead et al 1995) Adult females remain in a den for at least half the year. (Atkinson & Ramsay 1995) (Folk et al 1976)

I may be wrong here, but IMO there is no other mammal that is more protective of their young than a female Grizzly. She will die protecting her cubs. Almost gives way to this famous saying "Hell has no fury like a woman scorned" Not so. Female bear will sacrifice one cub to save another and herself. Male cannibal bears know this.

Never have I witnessed even the slightest hint of this crap you just dreamed up Kam.

'Brobear' its not "crap". It does happen. Black, Brown and White bears all do it. Hope this helps. Sven. Thats a male polar bear. kamchatka said females. We know cases of cannibalism of male brown bears also. Now show us a video or an account of a mother bear doing something wrong with her cubs.

Hi guys, I think you misunderstood the point'Kamchatka' was making. I read it as a mother bear sacrificing a cub to a male cannibal bear, rather than fight him and be killed too, as she can always have another one.
Also, if she has two cubs, the stronger, faster one will escape with her.
Hope this helps.
Sven.

But I have never seen in the many documentaries I have watched over the decades any evidence of this. Nor have I ever read in the great many books I have read any such happenings. No, I will need to read this within an actual biological study to believe it; or from a renowned bear-man. Until then, I will consider this as nothing better than spam.

Did you watch the linked video 'brobear'?
I might suggest you check National Geographic for further information, since they put their imprimatur on it, and had an 'expert' explain it.
Hope that helps.
Sven.

You have now. Well you would, if you'd watched the video.
Its great to learn some new facts about what bears do.
Hope that helps.

Ok Sven now i saw the video, yeah that particular female polar did not fight very hard for her cub, thats true. She wanted, but she saw that she would die also. Anyways, i bet you cant find a video like that of a female brown bear doing the same.

She was not willing to sacrifice her cub. She was simply unable to stop the huge male bear. In the end, she dove into the water, but knew she was too late. Not a sacrifice.

Ok but the polar bear biologist that spoke did say that happens and it will be happening more and more because of lack of food. The thing is i dont see a female BROWN bear doing something like that. I would be very surprised.

Anyways lets not leave this topic which is grizzly vs wolf pack.

I would be very surprised.I believe that the biologist was referring to cannibalism by big male bears and not to "bear cub sacrifice" which I saw no proof of.

Oh yeah definatly, we already knew about cannibalism. But that “sacrifice” yeah you are right. Its true though that in this case that female polar did not fight very hard. I dont think that is what usually happens.

I dont think that is what usually happens. Consider though, that while some bear biologists and other bear-men ( experts ) learn to read bears by body language, no one can read bear body language like another bear. It just might be a case of the mother bear realizing the futility of the situation. I have seen so many examples of this among so many other animals. An example that comes to mind, a grizzly runs right into a herd of bison and kills a calf as its mother watches helplessly. Sometimes, there's nothing you can do. We have witnessed ( how often ) as a mother grizzly charges right into a big boar grizzly nearly double her own size and ferociously drive him away from her cubs. But, the ultimate test would be... how does a mother grizzly react when her cubs are threatened by a tiger?

I'm going to say this about my favorite animal - Papa Bear is not a great role model for a father. Both lions and tigers make much better Dad's.
