Upon exiting hibernation, bears retain a reduced heart rate and basal metabolic rate. The metabolic rate of a hibernating bear will remain at a reduced level for up to 21 days after hibernation. [92]

In addition to the mainland grizzly ( Ursus arctos horribilis ), other morphological forms of brown bear in North America are sometimes identified as grizzly bears.
