Heavier bears are not much taller nor longer than lighter bears from my personal observation and the account of the two kamkatcha brown bears confirms that.

Heavier bears are not much taller nor longer than lighter bears from my personal observation and the account of the two kamkatcha brown bears confirms that. Well they had a 1 foot height difference. One was 10 feet tall, the other 9 feet tall. But sometimes the difference is even less.

Just across the Bering Strait from Alaska lives another gigantic brown bear–the Kamchatka brown bear (Ursus arctos beringianus) or the Far Eastern brown bear. Considered to be the ancestor of the Kodiak, the Kamchatka brown bears are dark brown and the largest carnivorans in Eurasia. These are the bears that were featured in the PBS special Walking with Giants: The Grizzlies of Siberia. The film documents the work of Charlie Russel and Maureen Ebbs–two naturalists who sought to discover some insight into the lives of the bears of the famed Kamchatka Peninsula of Siberia.

www.wcsrussia.org/en-us/wildlife/kamchatkabrownbears/ecology.aspxKamchatka Brown Bears: Ecology Alt Text A mother bear with 2 cubs on Kamchatka. Photo by Igor Shpilenok. Population and Distribution: Brown bears are one of the most widely distributed large carnivores in the world. The Kamchatka peninsula was once entirely populated with brown bears, and in remote protected areas is still home to the highest recorded density of brown bears on Earth. Increasing human access, through road development to expand mining and mineral exploration, is fragmenting the once continuous bear population, and Kamchatka brown bears are now becoming rare in some regions close to human settlements. Population estimates for the entire Kamchatka peninsula range from 10,000-14,000 bears in an area about the size of California. Population counts for the region are based largely on the casual observations of hunters and forest workers and are scientifically questionable. More than a decade has passed since the last aerial survey of the region, and there is a desperate need to redefine survey methods to monitor the long term trends in the bear population. Physical Description: Male Kamchatka brown bears can reach a weight of 700 kilograms, and are among the largest bears in the world. Their large physical size is a result of their access to rich food sources like salmon, pine nuts and berries. Maintaining body weight is crucial to survive the long period that bears spend sleeping in their winter dens (up to 6 months on Kamchatka). Reproduction and Life Span: Female brown bears in Kamchatka can begin to reproduce as early as 4 years of age and typically have litters of 2-3 cubs. WCS research has shown that some female bears with cubs do not approach salmon streams, to avoid risking their cubs being killed by another bear. By staying away from the salmon streams the females reduce the risk of cub mortality, but are also forced to survive on less rich food sources. Gaining enough weight to survive the winter is critical for female brown bears and their offspring. Cubs are born in the dead of winter in dens where the female is hibernating. Pregnant female bears that enter the den poorly nourished will often not be able to support their offspring, and the pregnancy will end before the birth of the cubs. The size of male brown bears is related to their social status and access to food and mates. Female bears must be induced into estrus, which means a male bear may have to follow a female bear for weeks until she is receptive to mating. During this time the male bears must fight off other male suitors. Females can produce offspring from different males in a single litter. Home Range: The area that a bear requires to fulfill all of its life requirements varies depending on habitat type and food sources available. In areas very rich in salmon, WCS research has shown that bears will maintain a home range as small as 12 sq km over the entire year. In areas where salmon and other food sources are scarce, however, home ranges can be as large as 1100 sq km. Data from GPS-collared bears showed that bears made movements of up to 65 km and crossed Kamchatka's central mountain range to access different salmon runs, crossing into different hunting leases and even leaving protected areas. Habitat: Kamchatka has some of the best brown bear habitat in the world. The highest concentrations of bears occur along streams during salmon spawning. Dense dwarf Siberian pine swales as well as expansive berry tundras can be rich feeding grounds for bears. Coastal sedge meadows and lush vegetation fed by heavy rainfalls are a bear “salad bar” when less rich food sources are available. In the fall bears in Kamchatka will usually excavate dens at higher elevations on south-facing slopes. Food sources: Salmon including: Pink, Sockeye, Coho, Chum, King, Cherry as well as char. Dwarf Siberian pine nuts, blue berries, crow berries, cranberries, mountain ash berries and others. Bears also feed on a wide variety of vegetation usually in the early summer. In some regions bear will hunt sea otters or be fortunate enough to find dead sea mammals like seals and even whales along the shore. 700 kg = 1,543 pounds.

By Spalea Andy Parkinson: " Kamchatka brown bear – Spending time with these magnificent animals it’s easy to forget their fearsome reputation, so accustomed had I got get to their close company. As always when I work abroad I am in the hands of local experts, Russian guides in this instance who knew these bears individually, often for as long as twenty years. It is from these guides that I always take instruction but lying on this tiny exposed sandbank there was little other option. With up to twenty bears completely surrounding us there were at times moments when my heart would race somewhat, a feeling of being exposed and utterly insignificant was not surprising given the scale of the majestic creatures that were everywhere. Whenever possible I would be lying on the ground, trying to create the impression of looking up at these incredible works of evolution, trying to convey their size and scale. In doing so of course it is easy to feel even more vulnerable, especially when a bear came galloping straight towards me in pursuit of yet another unfortunate fish. What I love about this image is its’ ferocity. So often with the images that I captured the bears would look benign and indifferent but there is no mistaking the capabilities of what stands in this image. His size is conveyed both by his proximity and by my perspective but it is the serendipitous moment of the fishes tail and the exposed teeth that really carry the message of why this is the apex predator of this remote wilderness. Looking at it now it seems almost unreal that I ever even lay there, completely surrounded by these astonishing animals and so busy with the task of image making that perhaps I didn’t really take it all in. Looking at this image now it’s nice to have the opportunity to absorb a little more, it’s an image that has certainly moved me. "

I mentioned here that the 3 biggest bears ever known to have lived in the Holocene are the Kodiak and (recently extinct) Californian brown bears of North America and the polar bear (which is present in the extreme north of Russia and Europe), in terms of maximum reported weights, but not necessarily in terms of breadth of skull. The largest of the Eurasian brown bears, that is the Kamchatka brown bear, has a skull which is broader than that of its Ussuri relative, and compared to that of the Kodiak bear, the breadth of the skull is much greater in proportion to its length, the anterior narial opening is much shorter, and the molars differ in relative size and form. The greatest skull length for males is 40.3–43.6 cm (15.9–17.2 inches), and they are 25.8–27.7 cm (10.2–10.9 inches) wide, while the skulls of females measure 37.2–38.6 cm (14.6–15.2 inches) in length and 21.6–24.2 cm (8.5–9.5 inches) in width: pubs.aina.ucalgary.ca/arctic/Arct...pdf#page=8, archive.org/stream/mammalsofsov2.../kamchatkaDespite being fairly large, weighing up to 650 kg (1,433 lbs) or more for males, Kamchatkan bears are generally not dangerous to humans, and only 1% of encounters result in attack. The first Europeans who went to Kamchatka in the 19th century, although surprised by the number and size of bears there, observed that they were relatively harmless, compared to their East Siberian counterparts. However, in July 2008, a platinum-mining compound in the Olyutorsky District of Kamchatka Krai was besieged by a group of 30 bears who killed two guards and prevented workers from leaving their homes: archive.org/stream/mammalsofsov2.../kamchatka, www.bearbiology.com/fileadmin/tpl..._Vol_9.pdf, www.kamchatkapeninsula.com/bear.html, www.timesonline.co.uk/tol/news/wo...387144.eceKamchatkan bear near Dvuhyurtochnoe Lake, credit: Robert F.

bearsoftheworld.net/kamchatka_brown_bears.asp The Kamchatka brown bear or Ursus arctos beringianus is closely related to the Alaskan brown bear. It is also known as the Far Eastern brown bear and is possibly an ancestor of the Kodiak bear. It was classified as an Ursus arctos subspecies in 1851 by zoologist Alexander von Middendorff . Ursus arctos crowtheri Drawing HABITAT Kamchatka brown bears can be found on the Kamchatka Peninsula, Karaginskiy Island, Shantar Islands, and Kuril Islands, in eastern Siberia. Their dens are often built under tree roots on dry slopes in September or October, about 30 days prior to hibernation. They may spend up to 6 months in hibernation. CHARACTERISTICS The Kamchatka brown bear's forehead is broad and is steeply elevated over its relatively short nose because of enormous sinuses. Its fur is long, dense and soft, and varies in color from pale yellow to blackish-brown to dull black. The bear's claws which are about 4 inches in length are a dark brown and sometimes have yellowish streaks at the tips. Males can grow up to 9 feet in length and weigh up to 800 pounds. Females can get up to 7 feet in length and 700 pounds. Males can be 50 to 53 inches shoulder height. Kamchatka brown bears can reach speeds of up to 30 miles per hour if necessary. DIET The large physical size of the Kamchatka bear is a result of having great access to sources of rich food like salmon, pine nuts and berries. It is of utmost importance that bears maintain their body weight in order to survive through hibernation. Because food is so accessible, the Kamchatka brown bears are of very little threat to humans. Only about one percent of all encounters result in an attack. BREEDING Female brown bears in Kamchatka are capable of reproducing at about 4 years of age. Cubs are born in winter while the female is hibernating. Pregnancies will end before birth if the mother too poorly nourished to support her offspring. There are usually 2 to 3 cubs per litter. Females can produce offspring from different males in a single litter. STATUS Kamchatka peninsula is home to the highest recorded density of brown bears on Earth. Population estimates for the peninsula range from 10,000 to 14,000 bears. However, increasing human access through road development to expand mining and mineral exploration is fragmenting the bears' habitat. Kamchatka brown bears are now becoming rare in some regions close to human settlements. As many as 2,000 bears are killed every year by poachers who come for the bear's gallbladder that sells for hundreds of dollars in the Asian market to use for folk remedies. Also placing the bears in danger are fishing industries seeking profit in the salmon, and decreasing the bears' richest source of food. The Kamchatka brown bear is considered to be endangered.

www.tapatalk.com/groups/animaluntamed/kamchatka-brown-bears-t874.html This is in response to Vodmeister and the rest of the bear haters on this forum who try to belittle any bear species at every turn. Vodmeister is the guy who wants to be "bear expert" on this forum so he can spread lies against the brown bear. This is the guy who didn't know the body mass of the European brown bear, in which i had to educate him on the European brown bear. A quote once stated by Vodmeister was this: 1200 pound Kamchatka Brown Bears? They're as real as 1200 pound Kaziranga Tigers, silly! Well i'm gonna give him another education on a brown bear sub-specie - Kamchatka Brown Bear. Kamchatka Brown Bear Program - Wildlife Conservation Society - Russia Research: By using GPS collars to study a number of aspects of brown bear ecology, WCS has obtained the best data ever collected on brown bears not only in Kamchatka, but in all Russia. Data from our first two GPS collars were groundbreaking, showing that, for example, brown bears maintain home ranges 10 times larger tham previously estimated by local biologists. This kind of information is critical to addressing conservation and management questions more effectively. In collaboration with Alaska Fish and Wildlife, WCS also is collecting tooth, hair, and tissue samples from trophy bears killed on Kamchatka. We use teeth to estimate the ages of the harvested bears, which will allow us to determine whether the average age has decreased because of extensive hunting pressure targeted at older, larger animals. Genetic analysis of tissue samples, in turn, will help determine if there is adequate gene flow among the bears of the peninsula. In cooperation with the Kamchatka Hunting Department, WCS has instituted protocols to collect and monitor data on bear-human conflicts, poaching activity and trophy hunting. The hope is that by reviewing historical data and trends, together we will be better able to direct future management and conservation actions. WCS has also conducted the first ever mark-recapture population estimate in Russia, with the aim to provide different scientifically rigorous methods of censusing bears. Other research on general bear ecology includes monitoring salmon consumption rates, vegetation forage, denning characteristics, as well as the social dynamics of bears around salmon streams. Physical Description: Male Kamchatka brown bears can reach a weight of 700kgs (1540lbs), and are among the largest bears in the world. Their large physical size is a result of their access to rich food sources like salmon, pine nuts and berries. Maintaining body weight is crucial to survive long period that bears spend sleeping in their winter dens (up to 6 months in Kamchatka).
