How long can a chipmunk survive in cold temperatures outside?

Chipmunks are not well-equipped to survive extreme cold for extended periods. They can tolerate cold temperatures by entering a state of torpor, which allows them to conserve energy, but this is usually for short durations. In general, their ability to survive in cold conditions depends on food availability, shelter, and the severity of the cold; they may hibernate for several months in winter but can only endure harsh outdoor conditions for a limited time without proper shelter and resources.
