Alaska Peninsula brown bears also known as the peninsular grizzly (Ursus arctos gyas) typically live along the southern coast of Alaska where there’s an abundance of seasonally spawning salmon.
These types of brown bears live along coastal Alaska from the Aleutian Islands as far west as Unimak, the Alaska Peninsula to the Kenai Peninsula.
Alaska Peninsula brown bears are very large. They usually weigh anywhere between 800 to 1,200 pounds. The size of the bear is highly dependant on the availability of food in surrounding areas.
These bears can reach 8 feet in length and usually have a shoulder height of about 4-4-1/2 feet. They also have a pronounced hump that appears on or between their shoulders.
The brown bears that live on the Alaskan Peninsula have access to seasonal spawning salmon. They usually wait at the bottom of the falls waiting for the fish to jump before catching them. When salmon is not available, these bears turn to eating berries and grass.
