If you’ve ever watched a chipmunk zipping around your yard, you might wonder if they’re bad news for birds. Honestly, yes—chipmunks will eat birds, but they usually go for eggs and baby birds, not adults. They aren’t fierce hunters, but they’ll raid nests if they spot an opportunity, especially when the parent birds aren’t around.
Most people know chipmunks for munching on nuts, seeds, and fruit, but they’re actually omnivores. That means they eat small animals too—think insects, baby birds, and eggs. Sometimes, you might even catch one nibbling on roadkill birds.
If you know this, you can do a better job protecting bird nests. Plus, it helps you see where chipmunks fit in your backyard’s little food web.
Will a Chipmunk Eat a Bird?
Chipmunks don’t just stick to seeds and nuts; sometimes they go after birds, eggs, and small animals too. It’s not super common, but it happens often enough that bird watchers and gardeners notice.
If you want to protect backyard wildlife, it helps to know when and why chipmunks eat birds.
Frequency of Bird Consumption by Chipmunks
Most chipmunks eat plants, insects, and occasionally small animals. Eating birds or eggs isn’t their main thing, but it does happen.
You might spot chipmunks near nests, especially in spring when eggs and baby birds are around.
Usually, chipmunks choose easier foods like seeds and insects. But if food gets scarce, some will climb up to nests and take eggs or nestlings.
They don’t exactly plan for it—it’s more about grabbing a protein boost when they can.
Why Chipmunks Eat Birds and Eggs
Chipmunks go after bird eggs and nestlings because they need extra protein, especially during breeding season or when other food is hard to find.
Eggs and baby birds give them nutrients they can’t get from just seeds or insects.
You might see chipmunks attacking nests to get this nutrition, either for themselves or their babies.
They climb surprisingly well for such small animals, so they can reach nests in bushes or low trees without too much trouble.
Opportunistic Feeding Behavior
Chipmunks eat whatever’s available and easy to grab. That includes insects, worms, fruit, nuts, and sometimes meat like small mammals, bird eggs, or baby birds.
If a chipmunk finds a bird’s nest, it might raid it if the timing’s right. This is just part of how they survive.
They don’t really hunt birds like true predators—they just take advantage of eggs or nestlings when easier food isn’t around.
Which Birds and Nests Are at Risk?
Ground nests or those on low branches are the easiest targets for chipmunks. Birds like robins, sparrows, and cardinals often build nests close to the ground or in thick bushes, making it easier for chipmunks to get to the eggs or chicks.
Nests hidden in tangled vines or thorny plants stay safer. If your garden has dense, prickly plants, chipmunks probably won’t bother with those nests.
But if you notice exposed nests, keep an eye out—chipmunks might visit them looking for food.

Understanding a Chipmunk’s Diet and Bird Feeder Interactions
Chipmunks eat all sorts of things and love to visit bird feeders for the easy seeds and nuts. Their diet shifts with the seasons, which changes how they behave around your feeders and nearby bird nests.
If you know what they like to eat, you can better protect both your birds and your birdseed.
Common Foods: Seeds, Nuts, Fruits, and More
Chipmunks eat both plants and animals, which makes them omnivores. You’ll often catch them snacking on seeds, nuts, berries, and fruit—the same stuff you find in most bird feeders.
They also scoop up grain that falls under feeders.
Besides plants, chipmunks sometimes eat insects, worms, and even small frogs if they get the chance. Their flexible diet helps them get through different seasons.
Because they love the same foods as birds, chipmunks can empty your feeders fast if you don’t do something to keep them out.
How Chipmunks Use Bird Feeders
You’ll see chipmunks gathering dropped seeds under feeders more than climbing the feeders themselves. But some chipmunks figure out how to climb poles or use nearby branches to get up there.
They don’t usually chase birds away on purpose—they’re just after the food. Still, birds might avoid the feeder if a chipmunk is hanging around, so chipmunks sometimes take over.
If your feeder spills a lot of seed, you’ll attract more chipmunks. Keeping things tidy under the feeder can help cut down on visits.
Seasonal Food Choices and Adaptation
During spring and summer, chipmunks eat more insects and worms for protein, which helps them grow and raise their babies.
Fruits and berries become more important in the warmer months.
In fall and early winter, chipmunks focus on gathering and storing nuts and seeds to get through the cold. If you have a feeder with nuts or sunflower seeds, expect chipmunks to show up.
They change their diet based on what’s around. That’s why you might see more or fewer chipmunks in your yard at different times of year.
Protecting Birds and Feeders from Chipmunks
You want to keep your birds safe from chipmunks. These little creatures often raid nests and eat eggs or even baby birds.
Try using bird feeders with cages or squirrel-proof designs. That usually stops chipmunks from grabbing the food.
Raise your feeders higher and move them away from tree branches if you can. Chipmunks are clever climbers, but making things tricky for them helps a lot.
Don’t forget to clean up seed spills under the feeders. If you let seeds pile up, chipmunks will just keep coming back.
Some folks sprinkle cayenne pepper or try other natural repellents. I’ve found that these methods can keep chipmunks away, and they won’t harm your birds.
You could also build safe nesting boxes. That gives chicks a better shot at avoiding chipmunks and other small predators.
