The Alaskan Grizzly is often dark brown, however it can also be blonde or black in hue. Their faces are slightly concave, and they frequently have a grizzled or light-colored hump between their shoulders. The length of their front claws is noticeable.
These bears come in a wide range of sizes based on their access to food. The size of interior bears is roughly two thirds that of coastal and island bears. Boars weigh between 300 and 900 pounds as adults. Sows weigh 200 to 450 pounds as adults. Adults typically stand 3 to 4 feet tall at the shoulders.
Alaskan grizzlies eat flora and ᴅᴇᴀᴅ animals from the previous winter after emerging from hibernation. They consume small mammals, plants, ɢʀᴀsses, sedges, roots, tubers, seeds, berries, and salmon. Additionally, they will prey on moose and caribou. When food is available, bears may feed in huge groups.
The typical hibernation period for Alaskan bears lasts from October or November through April or May, though sows occasionally don’t come out with their cubs until late June. In either January or February, pregnant sows will give birth to 1 to 4 cubs in the den. For up to two years, the cubs will remain with their mother. A quarter of adult males stay active all winter long without hibernating at all.
