For example: We know that polar bears average more than kodiak bears, but the largest specimens weighted were actually kodiaks. So by this logic its possible that the largest Ussuris get larger than the largest Kamchatkas correct. Exactly. I do consider the Kamchatka bear to be the largest subspecies of Russian brown bear where average size is concerned. But I would like to know their confirmed record weights. But this is difficult data to find. Hunters are skull collectors and biologists are clueless that some people outside of the scientific community are interested.

I have searched and cant find nothing on INDIVIDUAL record weights on the Far eastern brown bear. All we know is they get very big. 650 kg according to wiki, and 700 kg according to WCS Russia. Those are round numbers.

Those are round numbers. I'm sure these numbers are close. 650 kilograms is equal to 1,433.00 pounds (avoirdupois) 700 kilograms is equal to 1,543.24 pounds (avoirdupois)

Could be that you were correct after all, could be that the Ussuris get larger. Same situation with the kodiaks and polars. You have an estimate of 800 kg for Ussuris. Of course, very few bears get this big in general.

There are two problems with those estimations of the Amur brown bears. They are based on skull-size and footprints. However, brown bears, even within same subspecies, are much like humans. 1 - A bigger skull does not always belong to a bigger bear. 2 - Bigger footprints are not always left by a bigger bear.

I guess we will just have to do some more research and see.

shaggygod.proboards.com/ Size & Weight. Male polar bears weigh about 375-600 kilograms (825-1320 pounds) while occasional individuals may reach 800 kilograms (1760 lb). They sometimes exceed 250 centimeters (10 feet) in length, measured in a straight line from the tip of the nose to the tip of the tail, although most male polar bears are a bit shorter. They are roughly twice the size and weight of adult females, which weigh 200 to 350 kilograms (440-750 lb) and achieve an adult body length of about 190-220 centimeters (up to about 7 ft). Females first breed at four to six years of age and most often give birth to two cubs in snow dens on land (some cubs are born in dens on the sea ice). Cubs stay with their mothers for two and a half years before weaning which means that unless cubs die prematurely, females do not breed more frequently than every three years. Both sexes live twenty to twenty-five years and sometimes to over 30 years. Their primary prey is ringed seals and, to a lesser degree, bearded seals. The largest polar bear ever recorded was shot in Kotzebue Sound, Alaska in 1960 weighing a grizzly 1002 kilograms or 2,210 pounds and stood 11 feet 1 1/2 inches 3.39m in height. Height cannot be verified as this bear was mounted in an unnatural stance.

shaggygod.proboards.com/ Polar Bears: Approaching 600 kg, the Foxe Basin cohort are the largest specimens I have come across. "Size and Weight. The polar bear is the largest of the extant bears (DeMaster and Stirling 1981). In Hudson Bay, the mean scale weight of 94 males >5 years of age was 489 kg. The largest bear in that group was a 13-year-old, which weighed 654 kg (Kolenosky et al. 1992). The heaviest bear we have weighed in Alaska was 610 kg, and several animals were heavy enough that we could not raise them with our helicopter or weighing tripod. Some animals too heavy to lift have been estimated to weigh 800 kg (DeMaster and Stirling 1981)." Armstrup, C. Steven. 2003. Polar Bears (Chapter 27) in Wild Mammals of North America. 600 kilograms is equal to 1,322.77 pounds (avoirdupois) 800 kilograms is equal to 1,763.70 pounds (avoirdupois) Biologists, for example, rarely give names to the animals they handle, but one polar bear that Stenhouse and Nick Lunn caught on Southampton Island in 1985 was so big and burly -he weighed in at 810 kilograms (1,800 pounds) -that they nicknamed him "Stan." Stenhouse keeps a picture of "Stan" on the wall of his office in Hinton.

Stan, 1800 lb polar bear, You dont want to cross that one.
And the obvious happens here, polar bears are the ones that get larger in the wild, while kodiak bears are the ones that get larger in captivity.

And the obvious happens here, polar bears are the ones that get larger in the wild, while kodiak bears are the ones that get larger in captivity. True - all about food availability. No zoo ever fed their bears a better weight-gaining food item than pure natural blubber. When one considers that a big polar bear probably has several hundred pounds of fat above that of a Kodiak bear, then it becomes clear that the size difference between the two closely-related species is minor. Some bear "experts" place them equally as the world's largest members of the order Carnivora. But let's give credit where credit is due. The polar bear tops the scales as the biggest.

Agree. The biggest polar bear in the wild weighed over 2.000 pounds.

No zoo ever fed their bears a better weight-gaining food item than pure natural blubber. I have read that a Polar bear can have roughly 3-4 inches of fat beneath their hide. That is incredible, but also makes sense to be able to withstand the harsh conditions in the Arctic. A Zoo Polar likely doesn't have nearly the fat layer. Just like Horses that are outside during winter in the northern US, they develop a winter coat and likely the Wild Polar Bear's coat is decidedly thicker/heavier than a zoo Bear.

interesting-facts.com/nature/animal/polar-bear-facts/ We know from our polar bear facts that polar bears have a thick layer of hair near their skin. This hair can be up to six inches, or 15 centimeters, thick! Polar bears also have a thick layer of fat. This layer of fat, like the layer of fat found in whales, is called blubber. Polar bear blubber can be up to 4 inches, or 10 centimeters, in thickness! Putting those two facts together we arrive at one of our polar bear facts that tells us how well they have adapted for life in the Arctic regions. The layers of inner hair and blubber can be up to 10 inches, or 25 centimeters, thick combined! Can you imagine wearing a jacket that was 10 inches or 25 centimeters thick? It would be hard to move around. Most houses don’t even have insulation that thick! Evolution has given polar bears the best possible winter coat nature could provide. Another one of our polar bear facts that tells us about evolution is the difference between the claws on a polar bear and the claws on a brown bear. Polar bear claws are shorter and stouter. It’s speculated that this allows them to hold onto ice better.

en.wikipedia.org/wiki/Alaska_Peninsula_brown_bear The Alaska Peninsula brown bear is any member of the grizzly bear subspecies (Ursus arctos horribilis) that lives in the coastal regions of southern Alaska. Alaska Peninsula brown bears are a very large brown bear subspecies, usually ranging in weight from 800 to 1,200 pounds (363 to 544 kg). They are found in high densities along the southern Alaskan coast due not only to the large amount of clams and sedge grass but also to the annual salmon runs; this allows them to attain huge sizes, some of the biggest in the world. They may gather in large numbers at feeding sites, such as Brooks Falls and McNeil Falls, both in Katmai National Park near King Salmon. There is debate as to if Alaska Peninsula brown bears should be referred to as "grizzlies" along with all other North American subspecies of the brown bear. There is confusion experienced when referring to inland and coastal ones separately, but biologists still maintain that coastal ones are truly brown bears. However, it is considered correct to place all North American members of U. arctos in the subspecies horribilis except the giant Kodiak bears of Kodiak Island. To avoid confusion, many simply refer to all North American members, including Kodiaks, as "grizzly bears." Prized by hunters for their skulls and hides, up to 500 of Alaska's 1,500 brown bears killed yearly by hunters come from the Alaska Peninsula. To hunt this large bear, hunters must follow a variety of regulations, including bear bag limits, hunting fees and proper rifles. The Alaska Peninsula brown bear's name most likely arose because, until 1975, they were considered a different species from the inland grizzly bear. They were never considered closer to European brown bears than inland grizzlies, but were given a different name, due to the size and color differences of coastal browns and inland grizzlies. From 1975 onward, they were considered to be the same species, but coastal ones retained the name "brown bear. Alaska Peninsula brown bears are the second largest type of brown bear in the world, only after the giant bears of Kodiak Island. They usually measure 8 feet (2.4 m) in length, usually have a shoulder height of about 4-4-1/2 feet (1.2-1.4 m), and a hindfoot length of 11 in (28 cm). One study found that the average weight for a coastal male was around 408 kilograms (900 lb). For a female, this average weight would be 227 kilograms (500 lb). On the other hand, an occasional huge male brown has been recorded which greatly exceeds ordinary size, with weights reported up to 680 kg (1,500 lb). A large coastal male of this size may stand up to 3 metres (9.8 ft) tall on its hind legs and be up to 1.5 metres (4.9 ft) at the shoulder. The biggest individual on record was shot in 1948 near Cold Bay. Its weight was estimated at 725 kg (1,598 lb) to 771 kg (1,700 lb). This bear just came out of hibernation and carried little or no fat; that means the animal would have weighed around 839 kg (1,850 lb) at the end of the summer. Although variable from blonde to nearly black, grizzly bear fur is typically brown in color with white tips. A pronounced hump appears on their shoulders; the hump is a good way to distinguish a black bear from a grizzly bear, as black bears do not have this hump. Brown bears on the Alaskan Peninsula usually feed on spawning salmon, and use many different ways to catch them. These include waiting at the bottom of the falls for the fish to jump, or standing at the top of the falls waiting to catch the fish in midair (sometimes in their mouths). Bears also have much experience at chasing fish around and pinning the slippery animals with their claws. After the salmon runs, berries and grass make the mainstay of the bears' diets, after which they put on sufficient fat reserves and go into hibernation.

The giant short-faced bears were the absolute biggest bears ever. Your list gives the largest living bears. All of the genus Ursus. During the Pleistocene, there were a few bigger Ursus bears: The two giant European cave bears U. spaleaus and U. ingressus. and the European Steppe bear. Also, in more recent times. the California grizzly.
