A) Bears hibernate during winter, but aren’t sleeping the whole time. Hibernation for bears simply means they don’t need to eat or drink, and rarely urinate or defecate (or not at all). There is strong evolutionary pressure for bears to stay in their dens during winter, if there is little or no food available.

How long does a bear sleep in winter?
Hibernation can last anywhere from 4-7 months, triggered by seasonal food shortages, cold temperatures and snow cover. When the going gets tough, the tough get… sleepy. Time spent hibernating depends on environmental conditions and the sex and reproductive status of a bear.
How does a winter bear sleep?
Instead of hibernating, bears fall into a deep sleep called torpor. During torpor, heart rate and breathing rate decreases, body temperature reduces slightly and bears do not eat or release bodily waste. Bears can sleep more than 100 days without eating, drinking, or passing waste!
Can you wake up a bear in hibernation?
For hibernating animals like black bears, waking up early can be disastrous. For famous hibernators like black bears, predators such as mountain lions can present a threat during their winter rests. A more common one, though, is humans—not because they will attack a bear, but because they can wake it up.
Do bears poop when they hibernate?
According to the National Park Service, black bears and grizzly bears generally do not urinate (pee) or defecate (poop) while hibernating. During hibernation, poop (and other stuff) builds up in the bear’s lower intestine to form a fecal plug.
Do black bears hibernate?
Do Black Bears Hibernate? Black bears are not true hibernators. Instead, they experience what is often called denning, ursid hibernation or carnivore lethargy. This period of reduced activity occurs in all black bear populations.
What happens if you come across a hibernating bear?
Their body temperature drops. Their breathing and heart rates slow. Their body also starts to burn calories slower. These changes allow the bear to survive longer on its own body fat.
Can a human hibernate?
Humans cannot actually hibernate, but in the coldest months of the year, many of us are drawn to something similar.
Do bears eat during the winter?
Grizzly bears and black bears generally do not eat, drink, defecate, or urinate during hibernation. Bears live off of a layer of fat built up during the summer and fall months prior to hibernation. Waste products are produced, however, instead of disposing of their metabolic waste, bears recycle it.
Do bears give birth in their sleep?
Myth: Mother Bears Give Birth in Their Sleep, Wake up in Spring, and Are Surprised They Have Cubs. Untrue. The mothers’ metabolic rates are slowed by hibernation, but they wake up to birth and care for the cubs like other mothers do. Many “experts” spout this myth as fact without ever having seen a bear give birth.
Where Do bears sleep when not hibernating?
Most often they make a den under a rock, in a hollow tree, snuggled under a fallen tree, or in a brush pile. In the springtime, as snow melts and food sources become more available, bears wake up from their long hibernation. During the next few months, they rarely sleep at all.
How long are bears pregnant?
Do bears give birth in hibernation?
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. Females and their cubs usually emerge from their winter dens in late March or early April.
How do bears hibernate without dying?
Hibernating bears enter a shallow torpor with a decrease in body temperature of only 10 degrees. It’s metabolism and hear rate slows down. But it doesn’t need to eat, drink or pass waste. In order to survive, fat in the bear’s body breaks down into water and calories for the body to use.
How long does a bear sleep?
Bears can sleep more than 100 days without eating, drinking, or passing waste! Bears can actually turn their pee into protein. Unlike hibernation, torpor is not voluntary and often lasts for shorter periods of time.
Do bears eat rocks before hibernating?
Some of the fecal plug’s material is composed of undigested food that was eaten before the bear even entered its den. However, much is formed by cells that slough off the intestinal walls, rocks ingested by the bear during grooming sessions, and even bits of plant-based bedding.
Do snakes hibernate?
Yes, snakes do hibernate, just not in the traditional way we think of hibernation. Instead, they go into something called brumation in the winter. They have to go into this state of partial dormancy or partial sleep because they need to conserve energy for breeding and other activity in the warm weather months.
Do polar bears hibernate?
Polar bears do not hibernate. Only pregnant polar bears den. Unlike hibernation, a polar bear’s heart rate and temperate do not decrease, this ensures the cubs will stay warm. The denned polar bear does not eat, but relies on her fat reserves to sustain herself and her cubs while in the den (similar to hibernation).
What do bears do in the winter?
Most bears hibernate or den during the winter months. The length of denning depends on location, and can vary from a few days or weeks to a few months or more. Bears make their dens in hollow trees or logs, under the root mass of a tree, in rock crevices, or even high in a tree in warmer climates.
Do animals pee during hibernation?
Even those hibernators that don’t eat or drink anything at all sometimes defecate and urinate during hibernation (metabolizing stores of fat does produce waste), but these animals expel only a tiny amount during hibernation. Hibernating bears, on the other hand, can go the whole winter without going to the bathroom.
Why are bears not hibernating?
Bears in zoos will not hibernate if food is available, though they will slow down and sleep more than usual. Some zoo bears are fed year round, and do not hibernate. Since they do not undergo a winter weight loss like wild bears, some zoo bears can get very overweight, which is very unhealthy.
Where do black bears sleep at night?
In general, bears like to sleep after dusk and wake before dawn. Nevertheless, you can still come across bears at night, especially in Autumn and Spring when they’re actively seeking out food to fatten themselves up. They will sleep up trees, in bushes, and in secluded meadows.
What happens if you wake up an animal during hibernation?
If you were to wake up a hibernating animal midwinter, you would be effectively killing it. It would use up so much energy warming itself up in order to awaken that it would have no chance of making it to spring even if it could re-enter hibernation.
Can humans enter torpor?
The fact that large mammals such as bears and even primates, such as the fat-tailed dwarf lemur of Madagascar, can hibernate means that theoretically humans aren’t too big or energy-hungry to enter torpor.
How long does a bear live?
Do bears eat humans?
No, bears usually don’t eat humans. While bears do eat meat, they tend to stay away from humans, like most other wild animals. Humans are not part of a bear’s typical diet. But they do sometimes attack us, which causes an increasing number of people to seek out bear safety advice.

Can a black bear have 4 Cubs?
How many cubs do black bears have? A female black bear can produce a litter of up to five cubs every 2 years.
How long do black bears live?

Do panda bears hibernate?
Unlike other bears, pandas do not hibernate. At birth, panda cubs weigh only about as much as a quarter-pound stick of butter (90-130 grams) and have little fur. Adults can weigh more than 220 pounds. A panda’s average life span is 20-25 years in the wild and up to 30 in captivity.
Do black bears hibernate in Florida?
While Florida black bears don’t hibernate as long or deeply as their northern relatives to avoid the severe cold and lack of food, they do become much less active during the winter and some opt to stay in a den for chunks of time. This semi-hibernation state is called torpor.
Do hibernating animals sleep the whole time?
Despite what you may have heard, species that hibernate don’t “sleep” during the winter. Hibernation is an extended form of torpor, a state where metabolism is depressed to less than five percent of normal.
Why do bears abandon their cubs?
The large male bear is a physical threat to them, and they’d be wise to keep their distance. In this way, the cubs are prompted to leave the close proximity of their mother and begin to wander across the landscape alone, because mom no longer appears to be willing to defend them from the larger bear.
Do bears growl?
Unlike cats and dogs, black bears seldom, if ever, growl, although the fear-moans of treed or trapped bears are often mistaken for growls. Predacious attacks are silent, as is normal feeding and even play.
Do bears get pregnant every year?
Black bear females typically produce cubs every two years once they become mature. The 2-year reproductive cycle is genetically timed to fit the annual cycle of plant growth and fruiting of the region. In northeastern Minnesota, black bears mate in late May or June.
Do bears have umbilical cords?
Do bears have belly buttons? Like most mammals, bears are attached by an umbilical cord to their mother when born. But the navel scar that is left behind on bears is not nearly as pronounced as it is on humans. It usually fades quickly and is soon covered with fur.
Do bears hibernate with Cubs?
No Hibernation for Bear Cubs
The fast-growing young ones remain alongside mom, while nursing and resting themselves. Though the mother bears are usually asleep, they wake up occasionally to manage the needs of their cubs, whether by nursing them or by grooming them through licking.
How do bears have babies?

What month bears hibernate?
GPS data has also shown that bears often move into their dens, even traversing long distances, in advance of the first significant snow storm. Once the availability of fall foods fade, they will enter their den and begin hibernation (typically later in November, and December).
Why can’t humans hibernate?
Firstly, our evolutionary ancestors were tropical animals with no history of hibernating: humans have only migrated into temperate and sub-arctic latitudes in the last hundred thousand years or so. That’s not quite long enough to evolve all the metabolic adaptations we would need to be able to hibernate.
What month do bears wake up from hibernation?
A long wake-up for bears
Black bears emerge from their dens in April, but stay lethargic for weeks. During this so-called walking hibernation, they sleep plenty and don’t roam very far.
Do bears put things in their butt?
During the months when they are dormant, black bears have what is called a fecal plug that blocks their gastrointestinal tract. Much of this plug consists of hair that the bear ingests while licking its coat.
How do bear poop?
Bear scat is tubular like human feces but larger (5 to 12-inches long and 1.5 to 2.5-inches diameter). Black bear scat is most often found along trails or at the base of trees or plants. 1. SHAPE AND SIZE: Black bear scat is often tubular with a blunt end and a slight taper.
Do bears poop in the same spot?
Bears are using poop to mark their territories or feeding areas: FALSE. According to Michael Allen, bears have other ways to leave their signature. “Bears use trees or sign posts to leave their scent or bite/claw marks at about six feet high,” he wrote.
Do snakes fart?
And Rabaiotti did find that fart answer for her brother: yes, snakes fart, too. Sonoran Coral Snakes that live across the Southwestern United States and Mexico use their farts as a defense mechanism, sucking air into their “butt” (it’s actually called a cloaca) and then pushing it back out to keep predators away.
Where do squirrels hibernate?
Ground squirrels live on or in the ground and not in trees. Gray squirrels, however, sleep in tree nests during the winter and only venture out during the morning and evening. Instead of hibernating, they rely on sheltered nests or dens in trees, fat reserves, and stored food to survive the long, cold winter.
Do turtles hibernate?
Unlike other cold-blooded animals, turtles don’t hibernate. Instead of sleeping, they remain conscious while their body processes slow down. Turtles can’t breathe underwater, but in this state they don’t need to.
Which animals hibernate the longest?
Bats. When bats are left alone, they can be some of the longest hibernators. In the wild, big brown bats have spent 64-66 days in hibernation while in captivity one lasted an incredible 344 days!
Do grizzlies hibernate?
Contrary to popular belief, grizzlies don’t truly hibernate – they enter a state of torpor, which is a mild form of hibernation. Their body temperature dips to about 30-35°C, and their heart rate slows to around 8-19 beats per minute.
How long do black bears hibernate?
Black bears can hibernate for up to seven and a half months without drinking water, eating food or defecating. Grizzly bears typically hibernate between five to seven months. Mexican Black Bears usually do not hibernate at all or will hibernate for just a few weeks out of the year.
Do hibernating animals eat?
During hibernation, metabolism slows down. Animals that are hibernating do not eat. They use very little energy.
Can you wake up a bear in hibernation?
