California Bears

June 30, 2022

Question: I live in the foothills of the Sierra Nevada and a neighbor of mine said she’s seen a grizzly bear in the wild. Is that possible?

Answer: Black bears are the only wild bears in California. However, they do come in many different colors, from solid black to shades of brown and tan. Some have different patches of color, such as a white blaze on the chest or lighter colored muzzles.

People will sometimes claim to have seen a “brown bear.” Generally, the term “brown bear” refers to Ursus arctos, the grizzly bear. California grizzly bears became extinct by the 1920s and only the one on our state flag remains. There are two subspecies of black bears recognized in California: The northwestern or Olympic black bear (Ursus americana altifrontalis) in the northwest corner of California, and the California black bear (Ursus americana californiensis) throughout the rest of California. They are thought to be geographically distinguished from each other by the crest of the Klamath Mountains.

California’s black bear population is robust and has increased over the past 25 years. Since the extinction of the California grizzly, black bears have been able to expand throughout much of the state as they no longer face direct competition from the larger bear species.
