Along with sun bears, Asiatic black bears are the most typically used species in areas where bears are either used in performances or as pets. Asian black bears have an outstanding learning ability in captivity, and are among the most common species used in circus acts. According to Gary Brown:
Eurasian brown bear
The Eurasian brown bear ("Ursus arctos arctos") is one of the most common subspecies of the brown bear, and is found in much of Eurasia. It is also known as the European bear, common brown bear, common bear, and colloquially by many other names. "The genetic diversity of present-day brown bears ("Ursus arctos") has been extensively studied over the years and appears to be geographically structured into five main clades based upon analysis of the mtDNA."
