Alaskan Black bears aren’t as hard to find as you may think. How come? Because while they’re mostly black, black bears can also be white, brown, or cinnamon-colored. Some bluish-colored bears, called glacier bears, have even been found in Southeast Alaska. While both black and brown bears spend six to eight months a year preparing for hibernation, you can tell a black bear from a brown bear by their straighter, flatter face and shorter claws. After hibernation, black bears weigh 40 percent less than they did in the fall. Spring males weigh up to 200 pounds and females up to 150 pounds. They are the smallest of North American bears and have an incredible sense of smell.
