Unlike most people's impression, squirrels living in trees with big furry tails and chewing pine cones are actually just a small branch of the squirrel family.
From the snow-capped mountains above 6000 meters above sea level to tropical islands in the Pacific Ocean, from the western hemisphere to the eastern hemisphere, squirrel is active in various terrestrial habitats, and some of them still play an extremely important role in the ecosystem, except that the climate near the polar regions or the driest desert areas is extremely harsh and the vegetation is extremely simple or even absent.

Life habits of squirrels:
Squirrels almost live in trees and often use tree holes as their nests. They also build their own nests, choose to build them with twigs between hidden branches, and then pad them with soft debris, such as bird hair, animal hair, dead leaves, fresh moss and so on. Sometimes the old nest of the big bird is used as the foundation to repair it. Generally, it has several nests, which are divided into main nests and sub-nests. The main nest is used for night habitat and childbirth, while the auxiliary nest is temporary.
Males generally don't nest. He often lives alone and is active during the day, especially in the morning. Squirrels don't hibernate in winter, but when the temperature is low, they seldom go out for food and hide their long furry tails in holes to sleep. Its food includes pine nuts, acorns, chestnuts and various nuts. It often opens nuts with its front teeth and eats insects, eggs and chickens.
There is a habit of storing food in autumn. They were forced to move when food was in short supply. Squirrels are good at crawling and jumping, agile and lively, and have developed vision and hearing.
