Which bear species is most common in North America?

The American black bear is the most common bear species in North America. Its scientific name is Ursus americanus, and it is also the continent’s smallest and most widely distributed living bear species.

American black bears occupy much of Canada, Alaska, the United States, and parts of Mexico, especially in forests and mountainous regions. Their broad diet helps them survive in varied habitats: they eat berries, nuts, grasses, insects, fish, carrion, and other available foods. Their adaptability and relatively large population have allowed them to persist near human-modified landscapes.

“Black bear” describes a species, not a guaranteed fur color. Individuals may be black, brown, cinnamon, blonde, or even white, depending on the population. This variation can cause people to mistake a cinnamon-colored black bear for a grizzly. Grizzlies are brown bears, while polar bears are a separate Arctic species.

The American black bear is listed as Least Concern by the IUCN. Its population is estimated to be roughly twice that of all other bear species combined, although local populations can still face habitat loss, vehicle collisions, and conflict with people.
