When the squirrel jumps down from the tree, its big tail is like a parachute, so that the squirrel can fall to the ground safely. When it landed, its big tail was fluffy, thick and soft, which played the role of a sponge pad.

When the squirrel rests at night, it will put its big tail on its body and cover its head and body like a quilt to keep warm.

Squirrels are widely distributed in the temperate and cold temperate forest ecosystems of Palaearctic realm, starting from Iberia and Great Britain in the west, east to kamchatka peninsula, Sakhalin Island in Russia and Hokkaido in Japan, and south to the Mediterranean Sea, the Black Sea, northern Mongolia, northwest and northeast China.

Because of the relatively abundant and stable food sources, squirrels can maintain a high population density in coniferous and broadleaved mixed forests, and can use the small forests in suburbs and even cities to become companion animals.

Living habits

Squirrels are diurnal animals. They are active all year round and do not hibernate. The start time of their daily activities is related to the sunrise time, but the end time is not obviously related to the sunset time.

The daily activity rhythm of squirrels is influenced by climatic conditions, and strong winds, heavy rains, severe cold and heat will reduce the activity time of squirrels. The balance between the need for foraging and the need to preserve energy in the nest affects the squirrel's activity pattern in winter.

In winter, the daily activity rhythm is unimodal, and when it is cold, it will stay in the nest for several days. In summer, there is a peak activity in the morning and afternoon. The pattern of daily activities in spring and autumn is between winter and summer. .
