Polar Bear Mum & Cubs Exit The Den

Polar bears do not enter a state of deep hibernation; instead they undergo “walking hibernation.” Only pregnant female bears enter a den. They do so in the fall and give birth to their cubs in November or December. The bear family will remain in the den until March or April.

The cubs normally stay with their mother until they are 2 1/2 years old, although some bears in the Hudson Bay area wean their young at age 1 1/2. During the time that the cubs are with their mother, they must learn how to hunt and survive in one of the Earth’s harshest environments.
