Characteristics of the grizzly bear

The grizzly bear varies greatly in size and shape according to the region of North America from which it comes, although certain characteristics are maintained.For example, its structure is heavier than most species of bears.four legs are approximately the same length from each other, ending in long claws that can reach 8 centimeters in length, being larger than in black bears (Ursus americanus) or polar bears ( Ursus maritimus ).

The weight of these animals varies by region, sex, time of year and age, for example, adult bears of the Alaskan Peninsula, which usually feed on salmon, are the heaviest, around 360 kilograms .While the bears from a very close region, Yukon, when not taking fish, weigh just over 150 kilograms.Alaskan Peninsula weighs about 230 kilograms, while Yukon females do not usually exceed 100 kilograms in weight.Do, during the end of summer and fall, bears gain weight, which they lose later during hibernation .

Grizzly bears inhabit Alaska, Canada and the northwestern United States .In these regions there are many coniferous forests such as pines and firs, although their life is closely linked to the Wood from these trees, grizzly bears also need grasslands, scrubland areas and riparian vegetation.The most important population of these bears is the one found in Alaska, where they find abundant food for their needs.In addition, there are large areas to wander .These bears spend the day walking from one place to another in search of food, so their territories must be very wide.

Grizzly Bear Feeding

Like other bears, grizzly bears are omnivorous animals.On the Alaskan peninsula and Yukon, their main food to survive the whole year is salmon.Although they need a lot of practice, they end up being excellent fishermen.

Grizzly Bear Reproduction

The mating season of grizzly bears runs from May to July.During this period, males have a more aggressive behavior, being more protective of their territories and of the females that pass through them.When a male and a female meet, a procession takes place that includes chases and games for several hours.After copulation, both animals are They separate.

Grizzly bear females, like females of other bear species, are seasonal poliestrics with deferred implantation.This means that they may have several jealousy during the season and that, once It produces the copulation and fertilization, the egg is not implanted in the uterus until several months later., the young are born, between one and two .These, will pass with their mother between 2 and 4 years, until they become completely independent.
