The American black bear or Ursus americanus is a medium-sized bear native to North America. It is the continent’s smallest and most widely distributed bear species. They are omnivores, with their diets varying greatly depending on season and location.
They typically live in largely forested areas, but do leave forests in search of food. Sometimes they become attracted to human communities because of the immediate availability of food. The American black bear or Ursus americanus is the world’s most common bear species.
It is listed by the International Union for Conservation of Nature (IUCN) as a least-concern species, due to its widespread distribution and a large population. It is one of only two of the eight modern bear species not considered by the IUCN to be globally threatened with extinction.
Ursus americanus often mark trees using their teeth and claws as a form of communication with other bears.
Ursus abstrusus is the oldest known North American fossil member of the genus Ursus, dated to 4.95 mya. This suggests that U. abstrusus may be the direct ancestor of the American black bear, which evolved in North America.
They lived during the same period as the giant and lesser short-faced bears (Arctodus simus and A. pristinus, respectively) and the Florida spectacled bear (Tremarctos floridanus). These tremarctine bears evolved from bears that had emigrated from Asia to North America 7 to 8 ma.
They remained arboreal omnivores, like their Asian ancestors. The generalist behavior allowed them to exploit a wider variety of foods and has been given as a reason why, of these three genera, it alone survived climate and vegetative changes through the last Ice Age while the other, more specialized North American predators became extinct.
