Live squirrels in trees holes, they built for special nests of twigs covered with leaves.
Squirrels usually adopted in the northern hemisphere, strong winter custom nests.
These are built nests in dry foliage and the remains of a small Gulf trees.
May be used to build times lichen, parched grass.
This becomes the overall structure of the nest warm and resistant to weather.
Maybe I used a bunch of squirrels nest one in winter.
In summer, you may make a temporary nest, only consists of com Crown of twigs and leaves.
