Thirteen-lined ground squirrels can survive in hibernation for over six months without food or water and special physiological adaptations allow them to do so. [6] During torpor , these squirrels maintain hydration by redistributing and storing osmolytes like sodium, glucose, and blood urea nitrogen in different body compartments (to be ...
Some mammals hibernate, and reptiles enter brumation. But in some cases, animals aren't as capable of surviving the harsh conditions. Here's what Texas wildlife rehabbers suggest for animals in ...

Though they do not hibernate, they do become less active during the winter. Like many prey animals, they depend on auditory alerts from other squirrels or birds to determine safety.
The sharing of nests in winter by northern flying squirrels is important in maintaining body temperature (biothermal regulation), as northern flying squirrels do not hibernate, nor do they enter torpor states. Northern flying squirrels gliding distances tend to be between 5 and 25 metres, though glides of up to 45 m and longer have been observed.
