AP BIOLOGY

Detailed explanation-1: -Like many other arctic animals, arctic ground squirrels have unique physiological adaptations that allow them to survive during winter. Arctic ground squirrels are obligate hibernators and spend 7 to 8 months in hibernation.

Detailed explanation-2: -Ground squirrels hibernate from September to March, emerging from their slumber with gigantic appetites. They forage for food near their burrows, but will also gnaw on sprinkler heads, garden hoses, and irrigation lines. It’s not uncommon for the pests to chew through siding and insulation as well.

Detailed explanation-3: -Which animals hibernate? Small mammals, such as chipmunks, dormice, hamsters, hedgehogs and bats. Also, many insects, amphibians and reptiles.

Detailed explanation-4: -Most squirrels don’t hibernate-instead, they stash food for the cold season and spend the winter snug in their nests.

Detailed explanation-5: -During the winter, squirrels live in what is called dreys. The ground squirrels live in burrows and dens deep in the ground, while the tree squirrel lives in dreys on trees. Generally, squirrels build themselves a drey using branches and twigs for shelter.
