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.

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.
Black bear mother and cubs hibernating, utilizing a hibernaculum as a maternity den Like other animals, mammals hibernate during seasons of harsh environmental conditions and resource scarcity. As it requires less energy to maintain homeostasis and survive when an individual is hibernating, this is a cost-effective strategy to increase survival ...
Mother bears and their cubs have not had any difficulties hibernating, wildlife officials said. Half-asleep bears — unable to hibernate — seen walking around in Russia, officials say Skip to ...
Other organisms, such as a black bear, enter torpor and switch to multi-day cycles rather than rely on a circadian rhythm. However, it is seen that both captive and wild bears express similar circadian rhythms when entering torpor. Bears entering torpor in a simulated den with no light expressed normal but low functioning rhythms.
Avid hiker Michael Glidden was exploring ice caves 60 miles south of Anchorage, Alaska, when a storm kicked in. The temperatures dropped down to 25 degrees and it started to rain. Seeking shelter ...
Many of the physiological changes an American black bear exhibits during hibernation are retained slightly post-hibernation. 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]
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 ...
