The squirrels are mostly active during the day. In winter they do not fall into hibernation, but in cold weather they remain in their nest for days.
Adults build several nests, tree height.
They are usually built from dry twigs, lined with moss, noise or grass.
Sometimes they use cavities in the trees. Squirters often change their nests when they are filled with parasites.
Although they are cowardly animals and live singly, a couple can accommodate a few in order to warm each other.
