Individual bears vary in size seasonally, weighing the least in spring due to lack of foraging during hibernation, and the most in late fall, after a period of hyperphagia to put on additional weight to prepare for hibernation. [38] [39] Brown bear skeleton. Brown bears generally weigh 80 to 600 kg (180 to 1,320 lb), with males outweighing ...
Kodiak bears are the largest brown bear and are even comparable in size to polar bears. This makes Kodiak bears and polar bears both the two largest members of the bear family and the largest extant terrestrial [b] carnivorans. [4] The standard method of evaluating the size of bears is by measuring their skulls.
As an example of related species with differing diets, even though they diverged only 150,000 years ago, [7] the polar bear is the most highly carnivorous bear (more than 90% of its diet is meat) while the grizzly bear is one of the least carnivorous in many locales, with less than 10% of its diet being meat.

The BFQ was first applied by Wroe et al. (2005) in a paper comparing bite forces, body masses and prey size in a range of living and extinct mammalian carnivores, later expanded on by Christiansen & Wroe (2007). [2] Results showed that predators that take relatively large prey have large bite forces for their size, i.e., once adjusted for ...
A bear killing a human in a national park may be killed to prevent its attacking again. [140] Bear awareness programs have been developed by communities in grizzly bear territory to help prevent conflicts with both black and grizzly bears. The main premise of these programs is to teach humans to manage foods that attract bears.
Several bear species are dangerous to humans, especially in areas where they have become used to people; elsewhere, they generally avoid humans. Injuries caused by bears are rare, but are widely reported. [130] Bears may attack humans in response to being startled, in defense of young or food, or even for predatory reasons. [131]
