Bears are abundant in Alaska. Smaller fur-bearing animals include otter, beaver, mink, weasel, fox, lynx, wolverine, muskrat, rabbit, and several kinds of squirrel. Alaska also has a large number of wolves. Alaska is refuge for nearly 400 species of birds. Songbirds, sea birds, swans, cranes, ducks, and geese can be seen throughout the state, as well as predators such as hawks, falcons, several species of owl, and golden and bald eagles.
More bald eagles live in Alaska than in all other states combined.
Alaska's rugged shoreline offers sanctuary to more marine mammals than anywhere else. The world's largest colony of seals, numbering about one million, breed undisturbed on the Pribilof Islands. Walrus also thrive here. Sixteen kinds of whales have been spotted off Alaska's shores, including humpbacks, orcas or killer whales, snow-white beluga whales, and narwhals, which sport a single tusk similar to the mythical unicorn.
