polar bears eat, just like any other animal that hibernates.
Yes, polar bears eat up alot of food to last a whole winter and when they go into hibernation, they digest the food slowly, making it last the winter. This is all while they are in hibernation, they eat alot of food before they go into hibernation.
For black bears and grizzly bears, from spring to fall, with heightened periods when bears come out of hibernation and when they're fattening up for hibernation. For polar bears, it can be any time of the year.
'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.
Female polar bears dig a den in a snow drift, and have their baby's there.Polar bears have their babies in the den the mother made before winter. While hibernation, the mother sleeps with pregnancy till the babies come out and snuggle with their mom. Through hibernation the kids grow with the milk that they eat from their mother. After hibernation, the mother wakes up to find cubs in her den. And the life of the mother polar bear and her children continue.Cubs are born in the winter den.
They store food as fat. This occurs just before hibernation.
They don't.
Polar bears live on the shore line until ice forms on the sea. Then they travel out to the edge of the ice to hunt for seals. (Except the pregnant females, who spend the winter in hibernation.)
In the fall before hibernation because they have to pack as much fat on as possible to make it through the winter. During autumn the eat nearly non-stop.
Yes and they grow fatter and the store the food.
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.
The polar bear mother is very protective of her cubs (usually a pair of cubs). She will suckle the cubs while hibernating in a den dug into the snow.
So they can lock in heat in the cold winter surroundings and they can stay warm during hibernation.
