Alaska has three kinds of bears: black bears (Ursus americanus), brown bears (Ursus arctos) and grizzly bears (Ursus arctos horribilis), and polar bears (Ursus maritimus).

Black bears are the smallest North American bear. While black is a common color of their coat, the color can range from black to white, with brown, cinnamon, and even bluish shades in between.

Brown bears and grizzly bears are the same species. The tern "brown bear" is generally used to describe the coastal bears. Because they have access to the plentiful salmon runs, the occassional beached whale, and other sea food (such as clams, mussels, and other fish) and the coastal climate is a little more mild, these bears tend to grow larger than grizzly bears that live primarily in the interior.

Polar bears are considered marine mammals because they spend the most of their time on or near sea ice and are excellent swimmers. They are not commonly seen in parks, though occassionally they can be found in the Arctic parks of Bering Land Bridge National Preserve and Cape Krusenstern National Monument.

Alaska has amazing opportunities to view brown bears. Lake Clark National Park and Preserve and Katmai National Park and Preserve are two places where bears congregate to feed on salmon, but grizzly or brown bears can be seen in most parks. If you can't get to Katmai today, you can always check out the web cams to see what is happening out there.
