I also think this is a good thread to discuss Russian brown bear weights etc. The founder of Siberian Tiger Project measured the paw print width of a kamkatcha brown bear to be 18.5 cm yet in a chart which I posted in the big cat and bear tale thread in this link: https://wildfact.com/forum/topic-big-cat...#pid183709 it seems that even a 600 kg male Ussuri brown bear (only one recorded with that weight) has a 18cm paw width not much different from the 16.5 cm male Ussuri brown bear at 270kg. Perhaps the kamkatcha brown bear has proportionately wider paws.

Here's some information on the weights of Kamchatka and Ussuri brown bears. Ussuri brown bears and Kamchatka brown bears are the largest subspecies of brown bears in Russia, and larger than all other brown bear subspecies in Eurasia: MAIN MORPHOMETRIC CHARACTERISTICS OF BROWN BEARS IN KAMCHATKA AND SAKHALIN From other regions, representatives of the Ussuri subspecies living in the south of the Far East have large sizes comparable to those of Kamchatka bears. V.G. Yudin notes that individuals up to 450 kg are found in Primorsky Krai. The main morphometric parameters, primarily body weight and length, in Kamchatka bears turned out to be higher than in other regions, which gives reason to consider Kamchatka brown bears the largest in Eurasia. An additional study requires the morphometric characteristics of brown bears living in the Sikhote-Alin, which are comparable in size to Kamchatka bears. The brown bears of Sakhalin are somewhat inferior in size to the animals from Kamchatka, but, nevertheless, they are large and outnumber the bears from most other parts of their range. Thus, brown bears living in Sakhalin and especially in Kamchatka have a high trophy value and are a valuable resource for the development of hunting and tourism in these regions. https://www.researchgate.net/publication...D_SAKHALIN Ussuri brown bears and Kamchatka brown bears are both very similar-sized bear species. Both can attain the same maximum weights, except that Ussuri brown bears are more aggressive and predatory than Kamchatka bears. From Russian bear specialist and hunting biologist - Mikhail Krechmar Beyond the Urals, Primorsky Krai and Kamchatka have long been considered the focus of huge bears. Back in the middle of the last century, it was written about Kamchatka: "Black bears are found throughout Kamchatka in huge numbers, and without any doubt they would have exterminated the inhabitants long ago if they were not so meek and peaceful as anywhere else." “Huge bears come across along the coast of the bay (Peter the Great. - M.K.) at every verst, horrifying the soldiers with their height and furry appearance.” “The giant bears of Kamchatka are peaceful and herbivorous…” “The bears I met here undoubtedly belong to the greatest and most fearsome tribe of these animals, next to which the bears of Thuringia would seem like a Cocker Spaniel between the legs of a wolfhound…” The most surprising thing about all these tales is that in the scientific literature we do not find confirmation of such vivid impressions of travelers of the past. In the most exhaustive summary, Terrestrial Vertebrates of Eastern Kamchatka, the thoughtful researcher Yuri Averin gives measurements for more than twenty killed bears. The largest weight of the Kamchatka bear, according to his data, was 185 kilograms, females - 176. In the south of the Far East, detailed work on bears - brown and white-breasted - was carried out by Gordey Fedorovich Bromley. His largest male pulled 321 kilograms, the female - 199. https://www.livelib.ru/book/147686/readp...rechmar/~8 According to the weight data mentioned by Krechmar, the largest male and female Ussuri brown bears (321 kg, 199 kg) were larger than the largest male and female Kamchatka brown bears (185 kg, 176 kg) in those samples.
I stand corrected in regards to the chart: thanks for pointing out the east siberian brown bears which are one of the most overlooked of the three brown bears (kamakatcha brown bear, Ussuri brown bear, and east siberian brown bear) in the far east. I have always thought the Ussuri brown bear and Kamkatcha brown bear is comparable to the Peninsula grizzly bear and kodiak brown bear in certain ways, the former being more aggressive and carnivorous than the letter while the latter has a broader head than the former. I also believe the east siberian brown bear might be comparable to either the inland or barren ground grizzly bear.
I know it is brief but from this article, it seems the East Siberian brown bear is more carnivorous than the European brown bear: Code: Food: More carnivorous than European brown bears, will take mammals ranging in size from hares up to caribou (reindeer) and elk. Known to raid hunters’ food stores and huts for food. Data on diet is sparse but, in common with other brown bears, will eat a wide variety of vegetation, seeds, nuts, fruit, roots and tubers, small mammals, carrion and fish.http://www.bearconservation.org.uk/east-...rown-bear/ Quote:According to the weight data mentioned by Krechmar, the largest male and female Ussuri brown bears (321 kg, 199 kg) were larger than the largest male and female Kamchatka brown bears (185 kg, 176 kg) in those samples. Interesting information from Krechmar. In the first link you posted: https://www.researchgate.net/publication...D_SAKHALIN 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 this bear was large. (Got this info from Nyers). https://wildfact.com/forum/topic-tiger-p...#pid181109 It seems that some Ussuri brown bears can pass this maximum weight although it seems to be rare. An Ussuri brown bear at 800 pounds is definitely comparable in size. I am surprise the largest kamkatcha weighed by Krechmar is only 185 kg.

Yes, the Russian (especially Ussuri & east Siberian subspecies) brown bears are more predatory and aggressive than the brown bears from North America and Alaska. This probably explains why the Ussuri brown bears and east Siberian brown bears, being more carnivorous, have a more elongated and narrower skull than Kodiak brown bears and peninsula grizzlies. The 185 kg Kamchatka bear was not weighed by Krechmar, it was reported by the researcher Yuri Averin in his studies: "Terrestrial Vertebrates of Eastern Kamchatka". His weight data was just mentioned by Krechmar in his book. Surprisingly, his largest male Kamchatka brown bear wasn't even 200 kg.
According to Russian biologist & tiger/bear expert, Sergey Kolchin, Ussuri brown bears are not inferior in size to the Kamchatka and Alaskan brown bears:

I also visually noticed that Alaskan brown bears usually have a wider and more massive skull than Ussuri brown bears. Ussuri brown bears, on average, do have larger canines than the brown bears of Alaska though. Probably due to the Ussuri brown bears more predatory nature. Here's a huge male Ussuri brown bear that easily rivals some of the largest Alaskan and kodiak brown bears in body size; This bear looks very tall at the shoulders:  *This image is copyright of its original author
A female Ussuri brown bear and cubs being fed by residents on a highway in the Amur region:
 *This image is copyright of its original author Amur residents sent a video to the editorial office of Amur.life, in which a bear, living on the Tynda highway with cubs, rushed to the car of a passing man. The car lost its bumper in an unequal fight. Behind the scenes, the user comments that the meeting took place on July 10. In the first video, a man drives up to a she-bear, who goes towards her and tears off a piece of the bumper. After that, he drives off. The same video, but from a different angle, was filmed by men from a nearby car. The footage shows how the she-bear, having obtained a trophy, gnaws it. Bear cubs are playing in the background. As Amur.life reported , Amur residents constantly see this bear with cubs on the Tynda-Solovyevsk highway. Drivers passing by throw food at them. As eyewitnesses note, the clubfoot family is no longer just waiting for handouts, but demands them. And such behavior can develop into aggression. The Department for the Protection of Wildlife and Protected Areas of the Amur Region appeals to Amur residents with a request not to feed wild animals. By doing this, people do a disservice to predators - animals get used to feeding and in the future can go out to humans in search of food. ⠀ https://www.amur.life/news/2021/07/11/v-...hinu-video

Where can I find recent information on the weights and measurements of Ussuri and Kamchatka brown bears? They seem to be getting bigger and comparable to Kodiak bears.

I'll try another day. Here's a scientific study on the size of Kamchatka brown bears and brown bears of Sakhalin: Average weight and body lengths of adult male Kamchatka brown bears is 268.7 kg and 216.7 cm, and 174.9 kg and 194.5 cm for adult females: https://www.researchgate.net/publication...D_SAKHALIN Kamchatka and Ussuri brown bears are the same size and attain the same maximum weights (400 - 600 kg), and along with Kodiak and Alaskan Peninsula brown bears, are the largest subspecies of brown bears on earth. In fact, some individuals of Ussuri and Kamchatka bears can rival and even exceed the size and weights of some large male Kodiak brown bears. |
