The most common way squirrels store their food is by burying it in scattered caches around their territory to dig up later when food is scarce, such as in winter.
This way is usually favorable because it makes it harder for other animals or squirrels to pilfer their reserves as it's scattered in many different locations.
It was previously assumed that squirrels did not remember where they stored food, but rather uncovered it through scent. Squirrels do use smell partly to uncover buried caches, and they often find and steal at least a nut or two from other squirrels' caches, which they can detect by the odor. Scent can prove unreliable, however.
When the ground is too dry or covered in snow, squirrels are more interested in digging up their own food caches even when they can smell other caches nearby. According to the study "Grey Squirrels Remember the Locations of Buried Nuts," published in Princeton University's journal "Animal Behavior," squirrels use spatial memory often to locate stored food.
The study shows squirrels go back more often to their own food caches than to the caches of other squirrels, suggesting that they use memory to locate their food. Shop Online. Fun Facts About Squirrels Adult Squirrels can consume about one and a half pounds of seeds and nuts each week, which is roughly the equivalent of their own body weight.
