Extended data

Squirrels are mainly distributed in coniferous forests or coniferous and broad-leaved mixed forests composed of pine, larch and spruce. 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.

In the cold north, some squirrels hibernate in their nests like voles and bears. In the warm south, squirrels generally don't hibernate, but store food for the winter. People can still see squirrels in the wild in winter. The start time of squirrel's 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.
