What’s the most important thing to know about grizzlies?
Grizzly bears are small
Grizzly bears are small, but they are fiercely protective of their cubs. They rarely live past their first year, as nearly half of grizzly bear cubs die in their first year due to starvation, disease, or predators such as wolves or mountain lions.
Sadly, these animals do not have many human relatives, and they can be dangerous when they attack humans.
Grizzly bears are the second smallest species of bear. Adult males weigh about 300 kilograms and females weigh around 110 kilograms. Their fur is usually brown to black, and they are distinguished from black bears by their longer claws and humped shoulders.
Grizzly bears have a highly developed sense of smell and can communicate by marking trees with their scent. They are slow, but they can run up to forty miles per hour for short distances.
They are omnivores
Grizzly bears are apex predators that feed on both plants and animals. They typically eat plants but also take fish and smaller animals as prey. Grizzly bears may live for decades without eating anything for several months.
In the fall, they also gorge on fish and salmon. Grizzly bears also feed on rodents and birds. The food available to them is a rich supply, which allows them to maintain their population.
Grizzly bears reach sexual maturity around five years of age. During hibernation, grizzly bears mate with multiple males.
Embryos don’t fully develop until the mother goes into hibernation, but the female may miscarry if she does not gain enough weight before hibernation. Grizzly bear cubs stay with their mother for two and a half years.
They gain weight rapidly
Grizzly bears have high metabolisms and gain weight rapidly, making them dangerous to humans.
They have once roamed the western United States and the Great Plains, but are now confined to areas within National Parks and Wilderness areas. They require large amounts of space, a diet of abundant animal meat, and dens. Their ideal habitat is secluded and devoid of development.
During the fall, bears enter a state called hyperphagia, in which they overeat in order to fill their fat reserves.
On average, grizzly bears will consume approximately 30,000 calories a day during this period.
In coastal regions, grizzly bears can consume 60,000 calories per day. This state of hyperphagia is highly beneficial for the bears, but it can cause serious health problems in humans.
They are fiercely protective of their cubs
Grizzly bears are known for their ferocity and fiercely protective nature, and it is no wonder that they can be so difficult to see. Mother bears are fiercely protective of their cubs, and the first year of their life is the most delicate.
More than half of all bear cubs will die by the age of one, most often from complications such as river crossings.
Although grizzly bears may look intimidating, the fact is that they are highly social animals. They form hierarchies and establish structured kinship relationships. As a result, bear behavior is not as unpredictable as the media would have us believe.
Grizzly bears have predictable behavior, which can be beneficial for people who come into contact with them. Here’s how to understand their behavior and prevent them from harming you.
They are protected by law in the continental United States
The U.S. Fish and Wildlife Service is the primary federal agency responsible for making decisions on conservation efforts for all wildlife. Grizzly bears have been under attack in several states, particularly by trophy hunters, and need all the help they can get.
In fact, the agency recommended that grizzlies remain listed as threatened under the Endangered Species Act.
In addition, the agency has established recovery zones and programs that compensate ranchers who kill bears to protect livestock.
Grizzly bear numbers are now five times higher than they were in 1975 and are estimated to be between 1,400 and 1,700 in the contiguous U.S. Grizzly bears have also been listed under the Endangered Species Act twice and have been blocked by the federal government both times.
Grizzly bears used to inhabit the forests, grasslands, and meadows of North America, from California to the Great Plains and Alaska.
Unfortunately, human expansion and the changing landscape caused the near eradication of grizzly bears throughout the continental United States. Today, the bear population is only found in a small portion of its former range, and is at a critical point in their recovery.
