American Black Bearアメリカグマ
Ursus americanusLC— Least Concern
The American black bear is the most common and widespread bear species in North America, ranging across forested habitats from Canada and Alaska down through the continental United States and into Mexico. An adaptable omnivore, it eats mostly vegetation but supplements its diet with insects, fish, and occasionally small mammals. With stable or increasing populations across most of its range, it is classified as Least Concern by the IUCN.

Species Data
Did You Know?
- American black bears have been shown experimentally to learn visual color discrimination tasks faster than chimpanzees, highlighting their cognitive abilities. Source
- During hibernation, a black bear's metabolic rate drops to roughly a quarter of normal, and because it does not excrete waste, a hardened mass of fecal material forms in the intestine. Source
- American black bears survived the last Ice Age, when larger, more specialized North American bears went extinct, likely because their generalist diet let them exploit a wider range of food sources. Source
