Bears are wild animals and can be dangerous. It’s important to learn proper bear identification. There are a combination of characteristics to look for that can help you identify between black and brown bears. Knowing the difference between the two can help you make safe choices in bear country.


Brown/Grizzly Bears

Brown and grizzly are common names for the same species, Urus arctos; the difference between the two is geographic location, which influences diet, size, and behavior. Those that live in coastal areas of Alaska are called brown bears, while typically inland bears that have limited or no access to marine-derived food resources are often smaller and called grizzlies. Both have the same distinctive body shape described below. Bear identification:

  • Distinctive shoulder hump.
  • Rump is lower than shoulder hump.
  • Face profile appears dished in between the eyes and tip of the snout.
  • Ears are short and round.
  • Front claws are slightly curved and 2-4 inches longs, depending on how much digging the individual bear does.
  • Toes are close together, and form a farily straight line. A line drawn under the big toe across the top of the pad runs through or below the bottom half of the little toe on grizzly/brown bear tracks. Claw marks are often visible in the tracks.
  • Brown bears are larger than black bears, standing 3-5 feet at the shoulder when on all fours.


American Black Bears

 American black bears (Ursus americanus) are the most common and widely distributed species of bears in North America. They can be found anywhere from forested areas to the beach to the alpine zone.

The name “black bear” is misleading, however. This species can range from black to gray to cinnamon to white depending on the location and the individual. To ensure proper identification of an American black bear, do not depend on the bear’s coloration. Instead, look for a combination of the following features. Bear identification:
  • Shoulder lies level or flat with back/lacks shoulder hump.
  • Rump is higher than front shoulders.
  • Face profile is straight from between the eyes to tip of muzzle.
  • Ears are taller and more oval shaped and can appear to be very prominent on the head.
  • Front claws are less than 2 inches long and curved.
  • Toes are separated and fairly arced. A line drawn under the big toe across the top of the pad runs through the top half of the little toe on black bear tracks. Claw marks do not always show in the tracks.
  • Black bears are smaller than brown bears, standing 2 – 3.5 feet at the shoulder when on all fours.

When trying to identify a bear, do not rely on color and size alone, as they can be misleading. Instead, use tracks and the physical appearance of a bear to determine whether it is a brown/grizzly or American black bear. Bear identification is important for safe travel in Alaska wilderness.
