The brown bear is one of the two largest terrestrial carnivorans alive today, rivaled in body size only by its close cousin, the polar bear (Ursus maritimus), which is much less variable in size and averages larger due to this.

Brown bears are often not fully brown. Brown bears have long, thick fur, with a moderately long mane at the back of the neck which varies somewhat across the races. In India, brown bears can be reddish with silver tips, while in China, brown bears are bicolored with a yellow-brown or whitish cape across the neck, chest, and shoulders. North American grizzlies can be dark brown (almost black) to cream (almost white) or yellowish brown and often have darker colored legs.

Due to their claw structure, in addition to their excessive weight, adult brown bears cannot typically climb trees as can both species of black bear, although in rare cases adult female brown bears have been seen in trees. The home range of a brown bear is extremely large, reaching up to 2,000 square kilometers (770 square miles) in males, however they are not highly territorial.

Brown bears are omnivorous. Most brown bears are not highly carnivorous, as they derive up to 90% of their dietary food energy from vegetable matter. Their diet varies with the season – from grass and shoots in the spring to berries and apples in the summer, nuts and plums in autumn. All year round they eat roots, insects, mammals, fish, reptiles, and of course, honey.

In the Kamchatka peninsula and several parts of coastal Alaska, including Kodiak Island, brown bears feed largely on spawning salmon, whose nutrition and abundance explain the enormous size of the bears in these areas. In fall a brown bear may eat as much as 40 kilograms (90 pounds) of food each day, and it may weigh twice as much before hibernation as it will in spring.

4. Which of these brown bear characteristics are you aware of?

Brown bears hibernate throughout winter, preserving energy by reducing heart rate and body temperature by a few degrees. Hibernation takes place in a den, often dug into a sheltered slope, in which the bear may survive for over half a year without eating, drinking, urinating or defecating.

Brown bears mate from May to July, and a gestation of 180 to 266 days follows, with births occurring from January to March, usually while the female is still in hibernation. She generally lays down two to three offspring, and breeds again 2 to 4 years later.

Young born bears are vulnerable, being blind, naked and weighing only 350 to 510 g (0.77 to 1.12 lb). They feed on their mother's milk until spring or even early summer, depending on climate conditions. Cubs remain with their mother for some two and a half years.
