They do not form a single natural, or monophyletic, group; they are variously related to others in the squirrel family, including ground squirrels, flying squirrels, marmots, and chipmunks. The defining characteristic used to determine which species of Sciuridae are tree squirrels is dependent on their habitat rather than their physiology .
Eastern gray squirrels are crepuscular, [24] or more active during the early and late hours of the day, and tend to avoid the heat in the middle of a summer day. [40] They do not hibernate. [41] Eastern gray squirrels can breed twice a year, but younger and less experienced mothers normally have a single litter per year 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 ...
Ground squirrels and tree squirrels are usually either diurnal or crepuscular, [24] while the flying squirrels tend to be nocturnal—except for lactating flying squirrels and their young, which have a period of diurnality during the summer. [25] During hot periods, squirrels have been documented to sploot, or lay their stomachs down on cool ...
A recent phylogeny suggests the squirrels as a family can be divided into five major lineages. Red squirrels (Tamiasciurus) fall within the clade that includes flying squirrels and other tree squirrels (e.g., Sciurus). [6] There are 25 recognized subspecies of the American red squirrel. [7]

Douglas squirrels are larder hoarders, [7] storing their food in a single location or 'larder' called a midden. As the squirrel peels the scales of cones to get at the seeds, the discarded scales accumulate into piles that can grow to several meters across as the same site is used by generations of squirrels.
Turkish Vans will play in their water bowls or the toilet to get that beach vacation feeling. Among big cats, tigers, and jaguars are comfortable wading into jungle pools to cool off.
