Hibernation is a state of minimal activity and metabolic depression undergone by some animal species. Hibernation is a seasonal heterothermy characterized by low body-temperature, slow breathing and heart-rate, and low metabolic rate. It is most commonly used to pass through winter months – called overwintering.
A fecal plug (sometimes referred to as a tappen) is a significant biological phenomenon observed in bears and other animals during hibernation.It is a dense mass of hardened feces that forms in the colon due to having remained in the intestine so long that the intestinal walls have absorbed the fluids out of it, leaving it dry and hard.

Bears entering torpor in a simulated den with no light expressed normal but low functioning rhythms. The same was observed in wild bears denning in natural areas. The function of circadian rhythms in black, brown , and polar bears suggest that their system of torpor is evolutionarily advanced.
A grizzly bear at Maryland Zoo was captured on CCTV struggling to stay awake as hibernation season approaches. During their long winter sleep, the body temperature of a bear dips to about 30-35C ...
The male grizzly bear's hibernation ends in early to mid-March, while females emerge in April or early May. [53] In preparation for winter, bears can gain approximately 180 kg (400 lb), during a period of hyperphagia, before going into hibernation. [54] The bear often waits for a substantial snowstorm before it enters its den: such behavior ...
While black bears in colder, northern climates can hibernate for six months or longer, it is generally for shorter periods in North Carolina. But they do hibernate even along the N.C. coast ...
