Grizzly Bear

The grizzly bear (Ursus Arctos Horribilis) is a subspecies of the brown bear. It is native to Eurasia and reached North America 50,000 years ago.
It can be found in Alaska, western Canada, northern U.S. and in national parks.

Grizzly Bear Feed

Grizzlies are omnivorous animals, their diet consists of both plants and animals. These large prey animals attack animals such as elk, deer, sheep, bison, reindeer and even black bears.
They also feed on fish (salmon, trout) that they prefer for their taste and protein, everyone knows how nutritious and tasty the fish is. An alternative type of food is the carcasses of other animals.
Grizzlies in the Rocky Mountains of America are not as large as those in Alaska or Canada, and that's mostly due to their diet.
The difference is made by the roots, tubers, herbs consumed by them or by other animals they hunt, the fat content of salmon. Plants make up 80-90% of the diet of grizzly bears. These are: blueberries, blackberries, berries, strawberries, etc.more consume ladybugs, ants, bees if they are found in larger quantities.
When food is abundant, bears gather in larger and larger groups, and when food becomes scarce, they expand their territories, breaking up again in search of other food sources.
On the eve of winter bears can gain weight and 180 gk before hibernation. They often wait for blizzards and snowstorms before entering the pub for predators to sniff their trail as hard as possible. In some areas where food is plentiful throughout the year Bears skip the hibernation period.

Grizzly Bear Appearance

They are massive animals. They have a large mass of muscles on their shoulders that together with their long claws give them a great digging ability. The curved claws are longer than those of the black bear and reach 7-10cm, never less than 6cm.
Adults have developed massive powerful skulls that are large in relation to the body. The forehead is large, and the teeth are strong. The canines are large and curved. Although they have strong jaws they are unable to break large bones easily. Sizes vary depending on gender, age, geographic area, and diet.
They have a length of 2-3m, a maximum height of about 2-3m and a maximum weight of 1150 kg. It has long and thick fur, in northern subspecies it can reach 11-12 cm. In winter the fur is thin and rough to the touch.

Grizzly Bear Behavior

Grizzly bears have important links to the ecosystems in which they live. One of them is made with a plant that consumes its fleshy fruits. It removes its seeds through excrement in a germinating state(to germinate= to begin to develop, to sprout, to multiply, to start a new vegetation cycle).
Some studies have shown that germination did indeed increase due to nutrients in bear droppings. These things make the Bear have an important role in the ecosystem.
While searching for roots, plant bulbs, or other buried plants to feed himself, he digs the land.
Grizzlies are considered by some experts the most aggressive bears. Unlike smaller species of bears, they are too large to climb trees to escape attackers.
Grizzly females are the most aggressive, being responsible for 70% of attacks resulting in loss of life. Grizzlies normally avoid contact with humans. Despite their physical advantages they do not consider man a prey.
The largest stream where people meet grizzly bears is in the fall when they come to feed on salmon when fishermen come to fish.

Grizzly Bear Breeding

Grizzly bears have one of the lowest breeding rates in North America. They do not reach sexual maturity until the age of 5.
On average, the female grizzly gives birth to two cubs that she cares for until the age of two. If the Cubs move away from the bear or are killed she cannot produce others for about three years, depending on environmental conditions.
Male grizzly bears master large territories, up to 4000 square km, and finding a female partner is difficult in such conditions.
