1.

The Kodiak bear is a subspecies of brown bear that lives in Alaska. It is the largest of all brown bears and, along with the polar bear, one of the largest existing terrestrial carnivores.

 

2.

Despite its large size, these bears can reach a speed of up to 56 km/h (34,7 mph) over short distances and they are very graceful swimmers.

 

3.

These bears hibernate from October to May (adult males a little less) in most of the cases, but 25% of the male individuals remain active during the Winter too. They can sleep during 8 months without eating, drinking, urinating or defecating and wake up without having lost their muscle tone.

 

4.

Cubs are born with very low weight, very light fur and their eyes closed. The birth takes place in January/February in dens they dig in mountain sides. They spend a few months (until May or June) nursing to gain weight to leave. Females usually have 2 or 3 cubs.

 

5.

Kodiak bears are solitary and have no predators, but to cubs, adult males can pose a threat. These males will kill the cubs without hesitation in order to be able to mate again with the female. A high percentage of cubs die because of this.

 

6.

Despite being solitary animals, these bears can under certain circumstances live together with others. This happens especially in areas where the food is concentrated and it is known that this species has developed a complex language and social structure to avoid conflict.

7.

These bears can enjoy a habitat where the presence of humans is minimal, thanks to the creation of the “Kodiak National Wildlife Refuge” in 1941. It is also an area where food abounds.

 

8.

Their fur is more robust and longer than the fur of other subspecies of brown bear.

 

9.

They have poor eyesight but their sense of smell and their sense of hearing are excellent. This allows them to detect food from a far distance.

 

10.

Around 10,000 or 12,000 years ago, in the last Ice Age, these bears separated and isolated themselves from the other brown bears, reason why this subspecies differs more from the others.

 

11.

Females are sometimes seen with 5 or 6 cubs. This happens when they adopt cubs from other litters.

 

12.

Only one (the eldest) out of 2 or 3 cubs will stay with its mother for 5 years. The others will have to leave her side after 3 years. This raises the mortality rate, as they are less prepared to survive on their own.
