Brown bear is big is the biggest carnivore in the world, the dimension are different according with the subspecies, the Grizzly bear is usually between 170 and 280 cm long and tall at the shoulder is between 90 and 150 cm. The weight can be up to 650kg, when he stand up on the rear legs only he can arrive or even pass 3 mt. According with the researchers the brown bear dimension depend from the food availability, this is the reason because the kodiak bear is the biggest, he eat primarily salmons and this make him so big. Another proof is the dimensions reached in captivity where the biggest specimen when has died weighed close to 1100 kg. The dimensions listed up are referred at male specimen, the female are usually between 20 up to 50% of male.
The Brown bear prefer mountain places and he love the semi-open place. in the arctic region the global worming is creating new areas suitable for brown bear and at the same time is removing areas at the polar bear. In Eurasia the preferred habitat is the forest.
Where to find:
the 80% of the brown bear population is Alaska, Canada and Russia, the remaining 20% is fragmented in Europe and other areas near the biggest population.
brown bear is a very wild dangerous animal, its strength is great, imagine one paw with the front legs can break backbone of any animal. But is not a serial killer, his attack are classified and any time there is a specific reason, mostly time is victim’s mistake the origin of the attack. In North America the 70% of fatalities is by mother defending cubs.
The Alaska Science Center ranks the following as the most likely reasons for bear attacks:
Invaded personal space (this includes a mother bear protecting her young)
The data above are regarding the America’s brown bear, so in many other places the behavior can be very different but in any case, when you meet a mother with cubs stay far or die. I want to remark that this simple rule about mother and cubs is valid in all wild world for any animal specie.
The Brown bear don’t have any enemy, is alpha animal in his territory, the only competitor can be in some areas the Siberian tiger, where they share the same territory. Difficult to see fighting by adults of tiger and bear, usually if there is attack have as target the cubs or young specimen of the competitor.
Brown bear diet is 80% vegetable and the remaining 20% is hunting some prey, just in the case of kodiak bear for example the diet can be hundred % salmons and eggs of salmons. This is the reason because kodiak bear is the biggest of all subspecies of brown bear. If the brown bear need to be considered very danger is even true is danger in exceptional cases only, in the mostly case he meet humans he leave; he don’t like the human contact. unfortunately there are the exception like for example in Yellowstone Park, where tourists are a lot and they do camping, the bears is generally waste lover so if he feel the food’s smell he start to search it, up to devast tents or even cars, better don’t be there in that moment.
as usually two are the big risks for brown bear, the climate changing with the global worming and the human activities. Is generally classified Last Concern by IUCN red list but some subspecies in some areas are Engendered. In the case of Kodiak bear the situation is particular, the destiny of this bear is cruel, in kodiak island the hunt is permitted and regulated by ADF&G, every year 496 permits are released on front of a request of 4500, fortunately not all the hunters kill a bear and actually the number of killed is less then 200 per year, but the number is increasing. We know as sure the local residents collaborate with the authority for the respect of the law, they fight against the poaching in hunting and fishing and this is remarkable. There is no official data regarding the conservation status of the kodiak bear population because IUCN classify the brown bear and not the subspecies. We want to suppose which the population is stable, anyway remain the moral problem, to kill a specimen for to save another specimen is contradiction in terms, i think children understand better then adults this discrepancy.
As usually we hope reason and common sense will be used in the future for to protect this beautiful animal with humanity and love.
