Mine! All Mine: Why Squirrels Hoard

How do chipmunks and other animals know that they should hoard food for the impending winter months?


Studies have found that some animals never stop hoarding. This could mean the animals don't understand why they hoard, what it means for their future or even what future is. They simply do it out of instinct.

Eastern Chipmunks’ lifespan on average is only one year due to predators and man made dangers. They have two breeding seasons. The first begins in February and the second in June. They can have up to nine babies but average four.

Many people are frustrated by the amount of food they take away from bird feeding stations but chipmunks do have a purpose. They eat a lot of bugs and small rodents which humans can appreciate. And Mother Nature uses the chipmunks to spread plant seeds and fungi all around.

Eastern chipmunks live in shallow burrows made by digging and carrying away the dirt in their pouched mouths. These burrows can be up to 30 ft. in length with several different exits concealed with leaves and rocks.

The chipmunks’ cheek pouches also transfer food to their tunnels. They keep large stores of food in their burrows and build nests on top of this treasure. Eastern chipmunks, however, do not hibernate continuously through the winter, nor do they "fatten up" before retreating to their burrows. When the temperatures reach freezing, chipmunks go into their burrows to hibernate but wake up periodically to snack on their stored nuts and seeds.
