There are two subspecies of brown bears, and the Grizzly bear is one of them. The Grizzly bear appears in a dark brown or tan colour with short, rounded ears and a dished face; they have a large shoulder hump. Like the camels, the hump on the shoulder provides additional strength for the digging for the bear. The Grizzly bear has long claws, and it is a helping hand for it to dig its dens. The Grizzly bear weighs 315 kilograms, and the female bear weighs less than the male bear. The average life span of a grizzly bear in the wild is 25 years, and they grow up to five to eight feet.


The original habitat of the Grizzly Bear is the United States. Currently, the population of Grizzly bears is also distributed in Mexico. Canada and Alaska are the regions where most of the grizzly bears’ population is distributed. The familiar living places of grizzly bears are forests, woodlands, prairies, alpine meadows, rivers, and streams.

The Grizzly bear is a solitary animal that lives in the wild. We can spectate the gathering of grizzly bears in the prime Alaskan fishing spots. Their favourite food in summer is salmon, as the salmon run upstream during the summer. The grizzling bears survive during the winter by craving fats. Though Grizzling bears love to stay solitary, they live with females and with cubs. Grizzling bears have priority in the food chain as predators, as they eat other animals. Rodents to moose are the common prey of grizzling bears. Moreover, grizzling meat bears eat fruits, berries, nuts, leaves and roots.

The female bears give birth to two cubs at a time; they are usually twins. The labour is provided during the winter, rest inside dens. The eyesight and hearing of brown bears are comparable to humans, and they have a good sense of smell. The brown bears are excellent swimmers and have good movements on land. A Grizzly Bear can run up to 40 meters per hour.

Bear cubs are usually born in January and February, most during winter rest. Twins get born inside the bear dens. At birth, a cub weighs 7 kilograms, and the female grizzly bear looks after the cubs. The mothers get furious when they are in the period of protecting their cubs. Brown bears get sexually mature at the age of five years. The mating starts in spring, and there will be only one mating per year. The bear families stay together until the cubs’ age of two or three. The male cubs separate from the parents and leave the dens, but the female cubs will remain in the same place where they grew.

During the winter, the bears do not go hunting or in search of food; instead, they sleep in the den. According to the climate, the body temperature, metabolic rates and heart rates get reduced.


Grizzly bears are considered a threatened species. Especially in the habitats of Grizzly bears, in Canada and United States, their population has decreased to 1500. In the cold regions of Alaska, there is only a 31000 population of Grizzly bears which is a less count than in the past years. Humans excessively overhunt Grizzly Bears; therefore, The National Wildlife Federation has taken steps to conserve them by providing them with free space for their habitat and making a safe coexistence with human communities. Also, the Federations have taken steps to re-establish the extirpated population. There are laws imposed in Alaska and United States to conserve Grizzly bears.
