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 normally stock up on food then hibernate in their dens during the coldest winter months. Bear hibernation is “strongly tied” to weather patterns and food availability, according to a ...
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]
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.
For many bears, winter means hibernate or die. Here's what they do to survive. Plus: how climate change puts newborn cubs in danger.
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 ...
Bears of northern regions, including the American black bear and the grizzly bear, hibernate in the winter. [ 110 ] [ 111 ] During hibernation, the bear's metabolism slows down, its body temperature decreases slightly, and its heart rate slows from a normal value of 55 to just 9 beats per minute. [ 112 ]
That could mean shorter, or no, hibernation for male bears, increased pressure on winter food supplies, and a greater chance of human-bear conflicts as both species share the same space for longer ...
