Who’s getting fooled? Everyone knows that squirrels bury nuts to eat later. Researchers in Pennsylvania and Connecticut found that, interestingly, squirrels often dig a hole, then don’t bury a nut in it. When a squirrel knows something is watching, and digging up nuts a moment later, he may dig these fake burial holes to get the follower to give up (maybe a Blue jay, another squirrel or even a human). A squirrel may even re-bury a sloppily buried nut to make it harder to pilfer.
