Birds and squirrels can eat walnuts, and these nuts can be a nutritious part of their diet when offered safely.
In fact, walnuts are a natural food source for many backyard birds and squirrels, so as long as they’re plain and unsalted, they’re a safe treat.
You just need to make sure they’re free of mold and not coated in chocolate or seasonings.
In this post, we’ll take a closer look at why birds and squirrels can eat walnuts and how to feed them safely.
Let’s explore feeding walnuts to your backyard visitors so they enjoy this tasty snack.
Why Birds and Squirrels Can Eat Walnuts
Birds and squirrels can eat walnuts, and here’s why:
1. Walnuts Are a Natural Food Source
Walnuts come from walnut trees, which grow in many forests and backyards across North America.
Because these trees drop their nuts right onto the ground, squirrels have been eating walnuts for generations.
Birds like jays, crows, woodpeckers, and nuthatches also crack into walnuts when they find them.
So when you’re asking if birds and squirrels can eat walnuts, the answer is a clear yes since walnuts fit perfectly into their natural foraging habits.
2. Walnuts Pack Healthy Fats and Protein
Walnuts are loaded with fats, protein, and fiber that give birds and squirrels plenty of energy.
For squirrels, this fat content is especially important before winter when they need to build up reserves.
For birds, the protein in walnuts supports feather growth, egg production, and overall health.
This is a big reason birds and squirrels can eat walnuts and actually thrive on them.
3. Walnuts Offer Essential Vitamins and Minerals
Walnuts contain vitamin E, B vitamins, magnesium, and phosphorus.
These nutrients support a bird’s immune system and help squirrels maintain strong bones and teeth.
Since birds and squirrels can eat walnuts, these nuts act like a natural multivitamin for your backyard guests.
4. The Hard Shell Keeps Squirrels Busy
Squirrels love a challenge, and a whole walnut in its shell is the perfect puzzle.
Gnawing through the shell also helps wear down their ever-growing teeth.
So giving squirrels walnuts in the shell isn’t just feeding them, it’s also keeping their teeth healthy.
How to Feed Walnuts to Birds and Squirrels Safely
Now that you know birds and squirrels can eat walnuts, here’s how to serve them the right way:
1. Stick to Plain, Unsalted Walnuts
Raw or dry-roasted walnuts with no salt, sugar, or oil are the safest choice.
Salted walnuts can dehydrate small animals, and seasoned ones may contain onion or garlic powder, which is toxic to wildlife.
So if you’re wondering whether birds and squirrels can eat walnuts, remember it’s plain walnuts or nothing.
2. Avoid Moldy or Rancid Nuts
Walnuts can grow mold if stored in damp conditions.
Moldy nuts may contain aflatoxins, which are dangerous for both birds and squirrels.
Always smell your walnuts before feeding them, and toss any that smell bitter or musty.
3. Chop Walnuts for Smaller Birds
Tiny birds like chickadees and finches can’t crack a whole walnut.
Chopping walnuts into small pieces makes them easier for these little visitors to eat.
Squirrels and larger birds, on the other hand, will happily take the big chunks or even whole nuts.
4. Offer Walnuts in Moderation
Even though birds and squirrels can eat walnuts, too many can upset their diet.
Walnuts are high in fat, so they should be a treat, not the main course.
Mix walnuts with other foods like seeds, berries, and veggies for a balanced spread.
5. Skip Chocolate-Covered or Candied Walnuts
Chocolate is toxic to birds and squirrels, and candied walnuts are full of sugar.
These processed versions can cause serious health problems, so keep them for yourself.
Plain walnuts are the only kind you should share with wildlife.
Do Squirrels and Birds Eat Walnuts the Same Way?
Birds and squirrels eat walnuts differently, but both enjoy them just as much.
Squirrels typically grab a walnut and run off to bury or crack it open in a safe spot.
Birds tend to peck at cracked or chopped walnuts, or wedge a whole one against a branch to break it open.
Some birds, like blue jays, even cache walnuts in tree bark for later, just like squirrels do.
So yes, birds and squirrels can eat walnuts, and watching them tackle these nuts is half the fun.
