Although squirrels show relatively good scent relocation abilities, some food caches are never reclaimed, becoming seedlings in the spring. 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 greatest predator of the ground squirrel is a snake—the type of snake varying by the locality. As a result, ground squirrels have evolved to perform anti-snake displays to defend themselves. [6] These squirrels tend to be put on a prominent display, specifically by moving their tail back-and-forth horizontally.
This species hibernates over the winter. During the summers they gain extra weight in order to prepare for hibernation. [4] The squirrels hibernate in dens that can reach up to 100 feet in length although they are typically shallow in depth. [5] The breeding season commences when males and females emerge from hibernation in the spring.
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] They alternate between torpor bouts of 7 to 10 days when their body temperatures drops to 5-7°C, and interbout arousals of less than 24 hours with their body temperature back to 37 ...

Squirrels can cache as many as 3,000 nuts each season, but remembering where all the nuts are stored seems impossible. Unlike most small mammals whose brains shrink during winter due to reduced ...
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.
Rock squirrels are one of the largest members of the family Sciuridae, with adults measuring up to 21 inches (53 cm) in length. [3] In front and on top, the squirrel's coat is a speckled grayish brown; on the rear and bottom, the gray becomes a more mottled brownish-black tone.
