The American black bear (Ursus americanus) is a medium-sized bear native to North America.It is the continent's smallest and most widely distributed bear species.In The Variation of Animals and Plants under Domestication, Charles Darwin noted: In the nine-year Report it is stated that the bears had been seen in the zoological gardens to couple freely, but previously to 1848 most had rarely conceived.
The other 90% appear as normal-colored black bears.
Black bears currently inhabit much of their original Canadian range, though they seldom occur in the southern farmlands of Alberta, Saskatchewan, and Manitoba; they have been extinct in Prince Edward Island since 1937.
based on surveys taken in the mid-1990s in seven Canadian provinces, though this estimate excludes black bear populations in New Brunswick, Northwest Territories, Nova Scotia, and Saskatchewan.
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 estimated to be twice that of all other bear species combined.
Along with the brown bear, it is one of only two of the eight modern bear species not considered globally threatened with extinction by the IUCN.
