Behavior rhythm
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. The trade-off between the need for foraging and the energy left 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.
