'walking hibernation' means that the bears metabolism alters to a hibernation-like state which facilitates significant energy consercation. They remain active, but rely on stored fat for energy. This is a trait no other species of bear posesses.
when the polar bear enters walking hibernation, their metabolism goes to a hibernation-like level. the polar bear remains active, but relys on stored body fat. the polar bear is the only bear that does this.

Do polar bears estivate?
No, they do not hibernate in the winter either. The female does enter a state of near hibernation for the winter months in a den where she bears her cubs. The male is active year round.
Do squirrels in captivity hibernate?
Squirrels like most mammals will hibernate if the correct environmental factors exist. Squirrels, bears, and other animals that enter a state of hibernation (or torpor), do so because of extreme low temperatures and lack of food sources. Hibernation is a state that these animals enter, to reduce their metabolism and survive desolate seasons. Since in captivity these animals will not enter such extremes it seems logical they would not enter into any state of hibernation or torpor. As long as you feed them regularly and keep the thermostat to a solid 70 degrees Fahrenheit, they will not enter hibernation.
How do grizzly bears have babies?
When female grizzly bears enter hibernation, the embryo implants in her uterus and begins gestation. In January or February, female grizzly bears give birth to one to four cubs (usually two). The female will care for her young inside the den until spring, when they finally step out into the world.
Why do bears eat your trash?
There are two periods of time where bears are ravenously hungry, when they come out of hibernation, and just before they enter hibernation. During these times they are looking to fill up on as much food as possible as fast as possible, and our garbage smells really good to them. The problem is, that once they realize how easy it is to get a meal from our cast off food, they will return again and again until it no longer is a viable source.
How do Polar bears prepare for winter?
Polar bears present a mixed bag of responses to winter ... a female polar bear makes a den in which to give birth and then take care of her cubs, other polar bears remain active throughout the whole year. Interestingly some polar bears enter a state which is known as walking hibernation.As the Arctic winter lasts almost half the year, hibernating for the whole winter becomes problematic - they would starve to death even with the reduced energy demand during hibernation. All of the options require that the bears fatten up when the hunting is good. They do this during the spring. summer and fall.
Do bears hibernate or they just walk around?
no they just walk around this is called torpor it is still a deep sleep but not deeper then a hibernate sleep if you want the real answer just go on raz kids.com if you want the real answer go to level M then look on hibernation then read the whole thing im reading and right now i am on level M
What do brown bears do in the winter?
True hibernators experience a marked drop in heart rateand body temperature and generally stay for a long period in a den. Polar bears instead enter a state ofwalking hibernation where their metabolism slows. Only pregnant polar bears enter a den, give birth, and emerge three months later.-They hunt along the Arctic shelfs looking for tasty seals, fish, and even humans.
Do honey bears hibernate?
The Honey Possums don't hibernate for long periods of time as bears. But under certain circumstances they have to enter a short period of hibernation to conserve energy. They are nocturnal feeders normally, but they are known to feed during the daylight hours during periods of cold weather, also to huddle together for warmth. If the cold weather is combined with food shortages, the Honey Possums will drop into a deep torpid, or sleep, to conserve energy. This sleep, or hibernation doesn't usually last more than a day at a time, which is rare for such a deep torpid, or state of hibernation. For more details, please see the sites listed below.
Why does hiding and resting during the winter month when food is scarce help the polar bear?
Just like most other mammals, polar bears hibernate. Believe it or not, it actually gets a LOT more cold in the Arctic during the winter. This hibernation keeps it from freezing itself. As it eats, grows even more fat, and sleeps for a long period of time, the polar bear is kept warmer and safer from freezing almostmore than any other animal in the world!~ Foxes on a Television
Why do bears not hibernate?
In the true sense of the word, polar bears do not hibernate. While true hibernators experience a noticeable drop in heart rate and near 320F (00C) body temperature, polar bears do not. Instead, they experience what is known as "walking hibernation." In the fall, pregnant females enter the den, but males and non-pregnant females don't. They give birth to their cubs in the den in November or December. In March or April, the mother and cubs emerge from the den. They live in the Artic, which is always cold, so there wouldn't be much point in hibernating.The females den up in winter to give birth, but males remain active in all but the worst weather.Yes, they are just like other bears.Polar Bears do not ordinarily hibernate. When the temperature drops during the winter, many Polar Bears enter a state where their body functions will slow. This lethargy, drop in the body temperature and drop in respiration rate, are referred to as the "winter sleep". The Polar Bears are easily disturbed and awakened, and a female can give birth, and care for her young, while she is in this "winter sleep". Many times the degree of the inactivity or the depth of the "winter sleep" appears to be related to the weather, and the individual bears fat reserves. For more details please see sites listed below.Yes Polar Bears hibernate
Some polar bears go through long periods of sleep during the cold winter months In what two ways might their fat cells help the bears survive during these periods?
Before the polar bear hibernates, it eats tons of food, which then supplements it through the winter. Naturally, While the polar bear is sleeping, it's heart rate slows also allowing the food to with stand such a long period of time.
What animals come out of hibernation for autumn?
