Buried Goods
Squirrels take a substantial amount of time and effort to bury their winter goodies safely. They go to great lengths to conceal their hiding place from potential thieves. If a squirrel senses it is being watched, it will continue to dig a hole and pretend to drop something inside and close it back up. Quickly running away, it will move even further from the original spot to then actually bury the winter’s bounty. The thief will attempt to dig up the trick burial only to find nothing in its place. Squirrels also choose multiple hiding places to ensure that theft and damage are minimized. This is an intelligent strategy, save for one big problem.Lost Goods
Squirrels hide their winter treats in so many different places that they can sometimes fail to go back and locate every one. This can happen if a burying session was particularly stressful with increased predators or watchful eyes attempting to steal the stash. While squirrels have a mnemonic device to relocate nuts and seeds called spatial chunking, it can only do so much work. Having a significant number of locations in combination with stress can affect how memories are stored, thus limiting the squirrel’s access to returning to every burial location.
