Ever spot a chipmunk darting across your yard? It makes you wonder—what do these little guys actually eat?
Chipmunks mostly go for nuts, seeds, berries, and fruits. But they’ll also munch on insects, small eggs, and even mushrooms. Their menu is surprisingly broad, which honestly helps them get by through all sorts of weather.
It might surprise you, but chipmunks aren’t just into plants. Sometimes they hunt bugs, or even nab a frog or a bird egg if the opportunity pops up.
Since they spend a ton of time gathering food to stash in their burrows, you’ll often see them collecting whatever’s nearby.
Knowing what chipmunks eat can help you figure out how to protect your garden—or maybe even make your backyard a little haven for them.
Whether you’re aiming to keep them away or just want to watch them, understanding their favorite snacks gives you a pretty good window into their daily lives.

What Chipmunks Eat in the Wild
Chipmunks eat a huge variety of things, which really helps them get through the year.
You’ll find them nibbling on nuts, fruits, insects, and sometimes even small critters. Their food choices keep them healthy and ready for winter.
Seeds, Nuts, and Acorns
Seeds, nuts, and acorns are top favorites for chipmunks. These foods pack a punch for energy and are easy to store away.
You’ll often catch chipmunks stuffing their cheek pouches with these hard-shelled goodies.
Acorns? They love them. Acorns are full of nutrients and don’t spoil quickly.
Tree nuts in their shells are also a big hit, since chipmunks can haul them back to their burrows. Seeds from all sorts of plants add some variety and are everywhere in the wild.
These foods help chipmunks get ready for winter, when finding a snack gets a lot harder.
Fruits, Berries, and Grass
Chipmunks seem to really enjoy fruits and berries, especially those growing close to the ground.
Strawberries, blackberries, and wild berries are common treats you might spot them eating.
The sweet flavor gives them a little energy boost and keeps their diet balanced.
They’ll also munch on young grass and fresh green shoots. These soft plant bits give them moisture and extra vitamins.
If you’ve got a garden, don’t be shocked if you catch a chipmunk sneaking in for a nibble on veggies or grains.
Eating fruits, berries, and grass helps chipmunks mix up their nutrients all year long.
Insects, Bird Eggs, and Small Prey
Chipmunks aren’t just about plants—they go after animal foods too. They catch insects like worms and little bugs, which are packed with protein.
That protein helps them grow and stay active.
Now and then, chipmunks might find bird eggs to eat. These eggs give them a shot of fat and other nutrients.
It’s not super common, but sometimes they’ll go for tiny frogs or rodents.
Even though they mostly eat plants, adding animal matter gives their diet a boost, especially when they’re extra busy.
Fungi, Shoots, and Buds
Mushrooms and other fungi make it onto the chipmunk menu too. These pop up in the wild, usually not far from where chipmunks live.
Fungi offer different nutrients than other plants.
Chipmunks also like to eat tender new shoots and buds. These parts are easy to digest and loaded with vitamins.
Buds are basically the first growth after winter, so chipmunks get some fresh nutrition as soon as spring hits.
Eating fungi, shoots, and buds helps them stay healthy and roll with the changes in what’s available.
Foraging, Food Storage, and Eating Habits
Chipmunks keep busy looking for food and making sure they’ve got enough stashed away for lean times.
Their routines change with the seasons. They use their unique bodies and homes to protect and store their meals.
Foraging Behavior Across Seasons
In spring and summer, chipmunks go after fresh foods like fruits, insects, and nuts. You’ll see them darting around trees and bushes, using sharp eyes and a strong nose to sniff out snacks.
When autumn rolls in, they focus on gathering as many nuts, seeds, and grains as possible to prep for winter.
They stash food in several spots across their territory. This helps them find enough to get through hibernation or those cold, slow months.
Their foraging hits its peak before winter, especially for the Eastern chipmunk (Tamias striatus), which often stockpiles food for months.
Cheek Pouches and Food Transport
One of the cutest things about chipmunks? Their cheek pouches.
Chipmunks can cram a surprising amount of food into these stretchy pockets. That means they can carry tons of nuts, seeds, or berries back to their nests in just a few trips.
The pouches stretch from their cheeks all the way to their shoulders. When they’re full, chipmunks look like they’re carrying groceries for the whole neighborhood!
After gathering, they unload and either eat right away or stash the food for later. Using cheek pouches saves them time outside and helps them avoid predators.
Burrows, Nests, and Larder
Chipmunks dig out complex burrows underground or find snug nests in hollow trees. These homes give them a safe spot to sleep, raise babies, and store food.
Inside their burrows, you’ll find little rooms—some are just for storing food, called larders.
They hide food in these larders so it’ll last through winter, when chipmunks hunker down or stay pretty inactive.
The burrows usually have tunnels and a few exits, so chipmunks can make a quick getaway if they spot danger.
Careful storage like this is what really helps them survive the toughest months.
Differences in Diet Among Species
Chipmunk species don’t all eat the same things—it really depends on where they happen to live. The Eastern chipmunk, for example, likes to munch on acorns and beechnuts, plus the occasional fruit or insect.
If you look at Western chipmunks, you’ll see they go for more fungi or green plants, especially if they’re hanging out in dense forests.
Their diets shift with the seasons, too. When it’s mating season, chipmunks often hunt down more protein-rich foods, like insects or even bird eggs, since they need that extra energy.
But honestly, all Tamias species mix it up with nuts, seeds, fruits, and the odd small animal. That’s just how they keep themselves going.
