Does a bear sleep in a den?
A) Bears hibernate during winter, but aren’t sleeping the whole time. There is strong evolutionary pressure for bears to stay in their dens during winter, if there is little or no food available. But bears will leave their dens on occasion, particularly when their den gets flooded or is badly damaged.
Where do bears like to den?
Favored denning sites include hollow trees, if a bear can find one big enough — about three feet in diameter. Bears will also excavate dens under tree stumps, below the root mass of a blown-over tree, and beneath brush piles. Sometimes they use rock dens, typically along the base of a ledge.
Do bears give birth while hibernating?
During the winter denning period, pregnant black bears will give birth to cubs. Cubs are usually born within the first two months of hibernation. Cubs and their mothers stay in their dens for the rest of the winter while the mother bear rests and the cubs nurse and grow.

Bears are using poop to mark their territories or feeding areas: FALSE. According to Michael Allen, bears have other ways to leave their signature.

Depending on snowfall, temperature and food supply, bears get ready for winter hibernation in late November. The denning period in Yellowstone National Park is approximately 5 months. Grizzly bears and black bears generally do not eat, drink, defecate, or urinate during hibernation.
Where Do bears sleep at night?

The awe-inspiring brown bear lives in the forests and mountains of northern North America, Europe, and Asia. It is the most widely distributed bear in the world. The world’s largest brown bears are found in coastal British Columbia and Alaska, and on islands such as Kodiak.
What happens if you wake up a hibernating bear?
A bear that senses a threat can wake quickly to defend itself. That’s because bears’ body temperatures only lowers by a few degrees when they hibernate. This helps them become alert much faster, compared to other animals. In fact, bears can wake up and move around their dens during this time.
Do bears reuse their dens?
Dug dens often collapse after use and therefore are seldom reused. Bears also may den under the crown of downed trees or in brush piles. Some bears just rake up a bed on the ground near a windbreak.
Can humans hibernate?
And now it turns out that early human beings may also have been at it. They hibernated, according to fossil experts. The scientists argue that lesions and other signs of damage in fossilised bones of early humans are the same as those left in the bones of other animals that hibernate.
