Which bear species has the binomial name Ursus americanus?

The bear species with the binomial name Ursus americanus is the American black bear.

The American black bear is a North American species whose scientific name combines its genus, Ursus, with the species epithet americanus. It is native to Canada, the United States, and parts of Mexico, and is the continent’s most widely distributed bear species. Although commonly called the black bear, its fur can also be brown, cinnamon, blond, or even bluish-gray depending on the population.

The name can cause a common misconception: not every American black bear is black, and the species is not simply the American version of the Asian black bear. The two are separate species, though genetic studies indicate that they are more closely related to each other than either is to the brown or polar bear.

American black bears are adaptable omnivores. They typically use forests but may travel widely for seasonal foods such as berries, nuts, insects, and carrion. They are generally excellent climbers, and their broad range and large population have led the IUCN to classify the species as Least Concern.
