Burrows and Holes
Animals have lots of ways to use holes. Here are some:
- For hiding in
- For sleeping in
- For finding or storing food in
- As a place to have babies
- As shelter from bad weather
And did you know, mama polar bears dig holes in the snow?
When: In the fall.
Why: To give birth to her cubs. (Only polar bears having babies spend the winter hibernating in snow dens. That protects the tiny newborns from freezing.)
What's next: Come spring, it's time to leave the den. The little bears will follow Mom out onto the sea ice, where she'll hunt for seals. She needs good meals so she can keep nursing her hungry cubs.
