It’s hard to believe that grizzly cubs can be so small that they can Grizzlies may look lumpy and clumsyб but they are actually among the most strongest and fastest creatures on earth. They can reach speeds of 35-40 mph. and, despite its weight, could outrun the fastest man on earth. When grizzlies first come out of their winter dens, they are the thinnest they’ll be the whole year because they haven’t eaten in months. Their first meal after their winter hibernation would probably be a carcass of a moose or caribou that didn’t survive the winter. Grizzlies have to eat a lot in order to survive the winter when they hibernate.

Near the sea, grizzlies may find a beached whale or a dead sea lion or walrus. When the earth turns green they eat roots and sedges. Sedges are grasses that  grow in wetlands. They are important because they grow rapidly in spring and they are rich in protein. Grizzlies also eat nuts, insects, salmon and trout, and small mammals like squirrels. They may eat about 400 squirrels a year. Grizzlies can smell male and female fish. They like female fish better because of its delicious eggs. During the salmon season, a grizzly may capture 10 salmon and can afford to let some go. Though when salmon are rare, they will hungrily devour everyone they catch. Sometimes they eat only the head and eggs of a fish and disregard the rest. However, the rest doesn’t go to waste because gulls swarm nearby, ready to grab the leftovers. After the salmon run, grizzlies start on berries like blueberries, crowberries, and cranberries. However, they enjoy soapberries best.

A bear may consume 200,000 berries in a day. If the berry crops fail, grizzlies more likely to seek out human foods. In the fall, a grizzly’s droppings may be the berries they ate before. The North American bear, the grizzly bear, is found in Alaska, western Canada, and around The Rocky Mountains. In Alaska, the temperature may fall to 50 degrees below 0 in midwinter. Though during that time grizzlies are asleep in an underground den covered by a blanket of snow while they hibernate. For the matter of safety, about 200 grizzlies are living in Yellowstone National Park and around 500 to 600 are living Grizzly Bears prefer rugged mountains and forests undisturbed by human encroachment. They also live in arctic wilderness areas. Grizzlies need a lot of space. Large landscapes should be reserved for them if wished that the species survive.

However, they don’t require untouched areas. If they did, there would be much fewer left. Though they do roam free in the scraps of wilderness they have left. Grizzlies are both predator and prey. They are predators of squirrels, fish, caribou, wolves, Dall sheep, moose, and other small animals. They are prey to moose, caribou, and larger animals. So because of this, mother grizzlies fiercely guard her cubs. Grizzlies are true hibernators because they can go for 3 to 5 months without food. Even as long as 7 months in northern Alaska. They often dig dens on the side of a slope where snow collects, providing better insulation. Cubs are born in midwinter in litters of 1 to 4 depending on the local food supply. Twins are probably more common overall.

Mother grizzlies can reproduce until almost 30 years of age. Grizzlies can live up to 30 years of age. Though few survive beyond the age of 20. At birth, grizzly cubs are helpless and really small, but they grow fast, nourished by their mother’s milk. They are robust and playful by the time warm weather arrives for their first time. Grizzly cubs are very curious. That is characteristic they will retain in large measure throughout their lives. Cubs focus on their mother. By watching and imitating her, they will soon learn the business of being a bear. By a cub’s second year, they wade in to fish for themselves. Though they are rarely successful the first time. Two thirds of cubs die their first year. Although there is the possibility that some are lost to starvation or disease, marauding males are the only proven cause for the death of cubs.

Grizzlies mate in the spring and summer time in between May and July. When they first mate, females don’t become pregnant immediately. Males are thought to find their mate by smell from olfactory clues like scent left from rubbing posts. Grizzlies avoid contact with other bears until fishing season when it brings them shoulder to shoulder along streams. When 2 bears that have fought before meet again, the loser gives up its place to the winner to avoid another fight. Grizzlies are very strong. In a fight with another bear, they can grab their opponents teeth and throw him to the ground. Grizzlies do kill people, but visitors to mountain parks are more likely to be lightning than killed by a grizzly.
