Are Black Walnuts Good For Squirrels

Black walnuts are good for squirrels, and they’re actually one of the most valuable food sources a squirrel can find in the wild.
 
If you’ve ever watched a squirrel frantically burying black walnuts in your yard, you already know how much they love these rich, oily nuts.
 
The question of whether black walnuts are good for squirrels comes down to nutrition, and the answer is a resounding yes.
 
These nuts are packed with healthy fats, protein, and essential nutrients that squirrels need to survive harsh winters.
 
In this post, we’ll explore why black walnuts are good for squirrels, how they fit into a squirrel’s diet, and a few things to keep in mind if you’re feeding them.
 
Let’s dig in.

Why Black Walnuts Are Good for Squirrels

Black walnuts are good for squirrels because they provide a dense, energy-rich food source that supports everything from daily foraging to winter survival.
 
Here’s why these nuts deserve a spot on every squirrel’s menu:

1. Packed With Healthy Fats

One of the biggest reasons black walnuts are good for squirrels is their high fat content.
 
Squirrels need a lot of calories to stay warm, especially during cold months when food is scarce.
 
Black walnuts are loaded with unsaturated fats that give squirrels the long-lasting energy they need to keep foraging, climbing, and staying active.
 
That fat reserve is also what helps them build up the body weight they rely on to survive winter.
 

2. Rich in Protein

Black walnuts are also a solid source of protein, which is essential for muscle maintenance and overall health in squirrels.
 
Protein helps growing squirrels develop properly and supports adult squirrels through their active breeding seasons.
 
When a squirrel cracks open a black walnut, it’s getting a balanced mix of fat and protein that’s hard to beat in the wild.
 

3. Loaded With Essential Nutrients

Beyond fats and protein, black walnuts are good for squirrels because they contain important minerals like magnesium, phosphorus, and potassium.
 
These nutrients support strong bones, healthy nerve function, and a well-balanced internal system.
 
Squirrels that regularly eat black walnuts tend to be healthier and more resilient than those scraping by on lower-quality food.
 

4. A Natural Part of Their Diet

Black walnuts are good for squirrels simply because they’ve been eating them for thousands of years.
 
These nuts are native to North America, and squirrels have evolved right alongside them.
 
Their strong teeth are built to crack the tough outer shells, and their digestive systems are perfectly suited to handle the rich nut meat inside.
 
In other words, feeding black walnuts to squirrels isn’t just okay, it’s giving them exactly what nature intended.
 

How Squirrels Eat and Store Black Walnuts

Squirrels don’t just eat black walnuts on the spot, they also store them for later, which is another sign of how good these nuts are for them.
 
Here’s how squirrels make the most of a black walnut haul:

1. Caching for Winter

When a squirrel finds black walnuts, it often buries them in scattered spots across its territory.
 
This behavior, called caching, ensures the squirrel has food stored away when winter hits and fresh nuts are impossible to find.
 
The fact that squirrels go out of their way to stash black walnuts shows just how valuable they are.
 

2. Cracking the Tough Shell

Black walnuts have notoriously hard shells, but squirrels have the teeth and determination to get through them.
 
They’ll gnaw at the shell from a weak point until it cracks open, then dig out the nutrient-rich meat inside.
 
That effort pays off because the reward is a highly nutritious meal.
 

3. Eating Them Fresh or Dried

Squirrels will eat black walnuts fresh off the ground or after they’ve dried out a bit.
 
Either way, the nutritional value stays high, which is why black walnuts are good for squirrels no matter the season.
 

Things to Keep in Mind About Black Walnuts and Squirrels

While black walnuts are good for squirrels, there are a few things worth knowing if you’re feeding them or watching them in your yard:

1. Moderation Still Matters

Even though black walnuts are good for squirrels, too many can lead to an unbalanced diet if that’s all they’re eating.
 
Squirrels do best with variety, so black walnuts should be part of a broader mix of nuts, seeds, fruits, and natural forage.
 

2. Watch for Moldy Nuts

Black walnuts that sit on the ground too long can grow mold, which isn’t good for squirrels or any other animal.
 
If you’re putting out black walnuts, make sure they’re fresh and free of visible mold or decay.
 

3. The Trees Themselves Are Toxic to Some Animals

Here’s an interesting twist: while black walnuts are good for squirrels, the trees and hulls contain juglone, which can be toxic to certain plants and animals.
 
Squirrels, however, are unaffected, which is yet another reason they thrive around black walnut trees.
 

So, Are Black Walnuts Good for Squirrels?

Black walnuts are good for squirrels.
 
They’re packed with healthy fats, protein, and essential nutrients that squirrels need to thrive, especially during cold months.
 
Squirrels have evolved to eat and store black walnuts, and their bodies are perfectly built to handle these tough-shelled, nutrient-dense nuts.
 
Just remember that moderation and freshness matter, whether you’re feeding squirrels in your backyard or simply watching them enjoy a natural food source.
 
So if you’ve ever wondered whether black walnuts are good for squirrels, now you know the answer is a clear yes.
