Facts and Information That You Should Know About Grizzly Bears
[ad_1]
Grizzly bears are the subspecies of brown bears who subsist in North America. They are mostly found in Canada and the United States including Idaho, Washington, Wyoming, and Alaska. They usually like to stay alone although it does not always happen that way. The exception is when a mother bear has to nourish her cubs until they grow enough to start their own families. During the summer, they walk in a group at the fishing spot to catch salmon.
Most of them are covered with brown hair with gray or white tips. An adult male grizzly can grow up to eight feet long and weigh up to 800 lbs. In contrast, females may weigh around 350 lbs. Despite their giant physical structure, they can run up to 30 mph. An interesting fact about them is that they stand to get a better view of their surroundings.
They have robust shoulder and long claws, which are useful for digging up the roots. They also use their long claws to construct their dens during the winter. They are not like polar bears and they are omnivores. That means that they eat both meat and plants. They love to eat the flesh of other animals such as rodents and moose. In addition to that, nuts, fruits and berries are some of the other foods that they eat to meet their hunger. They are capable of eating around 90 lbs. food per day.
In order to store energy during the winter, they require fatty foods. When the climate turns cold, most of them create a den and start sleeping inside for a few weeks, which is known as hibernation. When they sleep, their heart rate slashes down to eight beats per minute from the average 40 beats per minute. Like polar bears, the female grizzlies also give birth to twins cubs during the winter. The cubs have no hair, and when they are born they are as small as the size of a chipmunk.
The cubs stay in the den until they grow enough to live on their own. They grow faster as they drink the milk of their mother which contains heavy amounts of fat and calories. The mommy grizzlies are very protective in nature, and they take very good care of their cubs. They even can attack humans if they feel their cubs are threatened.
The numbers of grizzly bears are gradually curbing down for many reasons. With the increasing number of the population, people started constructing buildings and roads to live and work. As a result, many grizzly bears have lost their habitats. Also, some of them were killed by wildlife officers when these grizzly bears started to enter the residential areas for food.
