Kamchatka brown bear

/\ Still the 1795 pound male Kamkatcha brown bear is heavier than Stan, the exceptionally large male polar bear.

However, I doubt the Kamkatcha brown bear will be as aggressive.

There is an unsubstantiated report of a 1130 kilogram (2490 lb) individual from Kamchatka.

We would have to see a confirmed report of a 1,795-pound East Siberian brown bear, which is normally somewhat smaller than an Ussuri brown bear, before we claim this as a fact.

I would have to read a biologists report to accept a 2,490-pound brown bear. I wouldn't call it impossible, but I give it a very strong unlikely.
Whoever estimated that bear's weight (I assume estimate) must have seen one extremely big bear.

I agree with everything you said. Unlikely but not impossible. They might be referring to the Bergman's bear (Ursus arctos piscator), a cryptid giant bear.

Male brown bears 7 yo and older

body mass: average 268,7 kg, min 180 kg, max 410 kg.
body length: average 216,7 cm, min 200 cm, max 249 cm.

palmar callus width: average 18.1 cm, min 17 cm, max 19 cm



The largest Kamchatka brown bear weighed by Seryodkin had a palm callus width of 19 cm, and weighed 410 kg.

So according to this data, the average weight of the Kamchatka brown bear 7 years old +, is 268.7kg (592 lbs), of course some of these were not all full grown specimens, so the average for just full grown specimens of 9 years old + would be higher. And it should be higher than Ussuri brown bears who average 286.4 kg (631.40 lbs) for 9 year old + specimens:

The largest specimen of Kamchatka was 410 kg (904 lbs), but of course, in this thread we will find much larger historical specimens.

So its clear to me, that looking thru this thread, the Kamchatka brown bear (9 + years) is larger both at average and max weights that the Ussuri brown bear.

[oldcyansilverback]

Not many Ussuri brown bears are larger than a 904 pound Kamkatcha brown bear (which is surprisingly similar in weight to the average Peninsula Alaskan grizzly bear). The 1000 pound to 1320 pound Ussuri brown bear is just as rare as a 1540 and 1760 pound male polar bear.

Back to topic, the record Ussuri brown bear (which is larger than all Kamkatcha brown bears) represents Van who is larger than all Kodiak bears and most male polar bears.At least that is my honest opinion.

The largest in Eurasia is the Kamchatka brown bear of eastern Russia.

Adult, male brown bears surpass females in weight by 30–50%; therefore, weight indicators are consid- ered separately in the review materials when possible.

The employees of Kronotsky Reserve pointed out that weighing the bears in the wild without using sedatives will be done for the first time. Moreover, in the past one could only determine the weight of Kamchatka’s largest land predators by weighing the carcasses obtained from hunting areas. According to available data, average weight of an adult male is 350 – 400 kg. At the end of the hyperphagia period it can exceed 600 kg.

Bobrinskiy et al. (1944) gave a maximum skull length of 445 mm. According to Johnson (1947) this bear attains a weight of 560 kg in winter.

/\ A 560 kg kamkatcha brown bear at winter weight will be weaker than a 560kg Peninsula Alaskan brown bear in my opinion. Regardless, it seems that fat does not inhibit the movement of the bear much nor do they get diabetes etc.
