Brown bear climbing down from the tree. Finland mid August 2020. They are really good climbers.

One big Kodiak bear, which was hunted fall 2014. Weighed 1417 lbs, which is same as 643 kg.
On video is hunting, if not wanting to see it, carcass and scale reading from 2:33-2:42.
Article from same hunt: https://miaanstine.com/2014/11/11/archery-alaskan-brown-bear-hunt/
Quote: "They kept saying it could be the biggest bear they had ever taken; so we figured out a way to get it loaded whole and took it back to the lodge. They flew in a hanging scale so we could weigh him. After gallons of blood loss he weighed 1,417 pounds. He would have been close to 1,450 pounds while alive. His hide squared 10’4”. He was 7’10” around the belly and 9’1” nose to tail."

I have thought sometimes if these Katmai bears are most extreme what comes to this change from spring to fall. This guy looks almost like a cub in that summer photo.
To compare in this photo is a bear from Finland and photo is taken June 15th 2020.

Update on Bear #791 (the Yellowstone Grizzly who killed a bull elk in September):
Currently estimated at ~600lbs or above, the 9y old brown bear successfully defended his elk carcass against various threats but ultimately lost out to an older and more experienced male.
We can see that experience is a huge advantage in conflicts between brown bears; #791 is larger than the veteran but lacks the "guts" to pose a serious threat. Give this bear one or two more years and I'll bet that the outcome would be different, he is on a good way to become the dominant male of Yellowstone National Park given his size (and we have to remember that Yellowstone grizzlies put on weight until they are 15y old; he hasn't even achieved his biggest possible size yet).

Ah, this was already here, for some reason I hadn´t noticed it. Anyway this is really interesting incident and great footage. A "must" for all who are interested in bears. Good to notice, that while you mention 791 to be estimated to be ~600 lbs, this older bear was weighed just before this incident to be 617 lbs, which is 280 kg. And 791 is clearly bigger, so it´s safe to say that at least well over 300 kg meaning something like 660-700 lbs or more.
RE: Brown Bears (Info, Pics and Videos) - Shadow - 11-15-2020
This is very good video concerning differences (and similarities) in between brown bears and black bears.
RE: Brown Bears (Info, Pics and Videos) - Shadow - 11-16-2020
It looks like there happened a bit more than earlier videos showed in between bears 881 (collar, 280 kg) and 791 (no collar, something over 300 kg, clearly bigger bear than 881).
Short clip, but there was a short confrontation with a bit biting too.

Thank you for the information, Shadow; regarding bear #881, is there any comprehensive document listing the weights of those modern Yellowstone grizzlies or are there just seperate individuals being weighed, would be good to get some fresh weight data. My only reference point for their size is the work by Blanchard dating back to the mid 70s/80s, maybe you can recommend some other valuable sources.
Regards,
Maritimus

I would try to contact to people who are behind that youtube account since they are working there at Yellowstone and they make informative videos. One person who might be able to help is @TheNormalGuy because he seems to be in contact with people who research wolves there. They for sure have information concerning bear research there too and who are doing field research concerning bears there.
RE: Brown Bears (Info, Pics and Videos) - Maritimus77 - 11-16-2020
@Shadow
Alright, I will take a look at that. May I ask where you got the 617lbs number for the grizzly #881 from?

I thought that you watched that video which you uploaded, it was there. They explained that situation from start to finish and gave information. Watch the whole video and pay attention and they tell that weight. I don´t remember now what time it was, but it´s told there. When some people use time to make so good quality video with information as that one is, I watch whole video and I strongly recommend that people who are interested about these animals do so too. Not just quickly searching for "action".
That video is really interesting to watch and see what those people say.

I once came accross a list of weight of yellowstone grizzly bears. Wait a sec

BIOLOGISTS CAPTURE, COLLAR GRIZZLIES NEAR YELLOWSTONE GENERAL | SEPTEMBER 30, 2020
18 grizzlies were captured ^
Quote:Radio-Collaring Bears
IGBST began radiocollaring grizzly bears in the Greater Yellowstone Ecosystem (GYE) in 1975. Since then, we have radio-monitored over 830 individuals for varying durations, typically for 2 to 3 years. Over 100 individuals have been monitored during more than 5 different years.
