A Kodiak bear’s coat may range from dark brown to nearly blonde. Bears are typically darker in the fall when they begin growing their winter coat, and older bears are often darker than younger bears, but these are just generalizations. One cub from a litter may be light, while his brother is dark brown.
Cubs often have a natal collar, a white band around the neck and shoulder. Some cubs have no natal collar, and others have a collar that is bright and distinct. This band gradually fades over time, and it has usually disappeared by the age of three, but occasionally, you will see a four-or-five-year-old bear that still has remnants of a collar.
A bear’s fur is an excellent insulator. It is dense and oily, keeping the bear warm and preventing water from penetrating. The fur consists of two types of hair, the “guard hair” and the “under-fur.” Bears shed both the guard hair and underfur annually. In the summer, Kodiak bears often appear shaggy and matted. The bear in the photo below looks as if she is sporting dreadlocks. To help remove their fur, bears rub against trees and rocks, often standing on their hind legs, backing up to a tree and rubbing up and down. It is humorous to watch a bear “scratch his back” in this manner. While the old coat is shedding, a new coat is growing, and by September on Kodiak, most bears appear darker in color and well-groomed. The old, loose fur is gone, and only the new fur remains.
Brown bears have non-retractable claws up to four-inches long. The claws of young bears are typically dark brown and then lighten with age. Although some young bears have light-colored claws, beautiful, pearly-white claws are usually seen on an old sow or boar. Look at the photos and notice the difference in claw coloration between the sub-adult bear and the old sow.
Brown bears use their claws to defend themselves and fight with other bears, but Kodiak bears primarily use their claws to dig for roots and other food and gripping food. Even though their claws look large and clumsy to us, they are quite dexterous and capable of manipulating small objects. Kodiak cubs use their claws to climb trees, but adult brown bears are poor climbers due to their body weight and the structure of their claws. It is not uncommon to see a sow send her small cubs up a tree if she senses danger, and they stay in the tree until she vocalizes the signal that it is safe for them to come down.
