Gray, fox, and red squirrels sleep in their nest, which is called a drey. It is composed of twigs and sticks and then lined with moss, strips of bark, grass, and leaves. The nest is usually built in the fork of a tall tree but can also be constructed in the attic of a house or in the outside walls of a home.

Where do squirrels go at night?

The simple answer is that tree squirrels sleep in trees and ground squirrels sleep in the ground. Tree squirrels also often live alone while ground squirrels often live in groups. The tree squirrels tend to live in nests that are built from a collection of twigs, leaves, and other natural materials.

Where do squirrels sleep in the winter time?

Ground squirrels live on or in the ground and not in trees. Gray squirrels, however, sleep in tree nests during the winter and only venture out during the morning and evening. Instead of hibernating, they rely on sheltered nests or dens in trees, fat reserves, and stored food to survive the long, cold winter.
