For many animals, though, the “store" isn't open year-round. For example, many plants and trees only produce edible products like fruit and nuts at certain times of the year. If animals are going to have enough food to survive the winter, they often need to set aside some for later.
One animal you may have seen storing nuts for the winter is the squirrel. That's why some people call storing up food for the winter “squirreling" food away.
Squirrels aren't the only animals that store up food for the winter. Wildcats often bury small prey, such as birds. Moles store up earthworms in mounds. Foxes might store eggs or bones in shallow holes. Mice scatter hoard seeds and nuts in underground nests.
When squirrels and other animals scatter hoard food for the winter, how do they know where to find it again? Some experts believe they don't necessarily remember where they hid food. Instead, they just use their sense of smell to sniff out buried food.
Some squirrels even get tricky with their food hiding. Scientists have learned that some squirrels bury fake nuts. To fool other animals, they dig holes but bury nothing in them. They just pretend in order to make other animals think something is buried there!
