There are numerous reasons why bears cannot be placed in the same category as true hibernators. These include the following:

· Their large body mass inhibit them from experiencing a marked reduction in body temperature, metabolic rate or heart rate

· Bears have full sensibility and use of their facilities and are capable of coordinated movement

· Female bears are able to give birth during dormancy

· Bears are easily aroused even in their most lethargic state and may awaken several times during the period of dormancy
