Do Squirrels Eat Green Walnuts

Squirrels do eat green walnuts, and they often go after them before the nuts ever have a chance to ripen.
 
If you’ve ever watched a squirrel scramble up a walnut tree and start gnawing on something hard and green, you already know the answer to the question: do squirrels eat green walnuts?
 
Yes, squirrels eat green walnuts, and for them, it’s not just a snack but a smart survival move.
 
In this post, we’ll dig into why squirrels eat green walnuts, how they manage to get through that tough outer husk, and what it means for your walnut trees if these bushy-tailed foragers move in.
 
Let’s get right into it.
 

Why Squirrels Eat Green Walnuts

Squirrels eat green walnuts for a few very good reasons, and once you understand them, their behavior makes perfect sense.
 

1. Green Walnuts Are a Rich Food Source

Green walnuts are packed with fat, protein, and carbohydrates, which is exactly what a squirrel needs to stay energized.
 
During late summer and early fall, squirrels are bulking up for colder months, so they eat green walnuts whenever they can find them.
 
Even though the nuts aren’t fully mature, the developing kernel inside still offers solid nutrition.
 

2. They Beat Other Animals to the Punch

Squirrels eat green walnuts partly because timing matters.
 
If they wait until the walnuts ripen and drop, deer, birds, and other squirrels will compete for the same food.
 
By eating green walnuts early, squirrels secure a meal before the rush begins.
 

3. The Husks Are Soft Enough to Chew

A green walnut husk is tough but not impossible.
 
A squirrel’s teeth are sharp and constantly growing, so they can gnaw through the outer layers of green walnuts without much trouble.
 
Once they break through, they reach the shell and then the nut inside.
 

4. Green Walnuts Store Well Underground

Squirrels often bury green walnuts for later.
 
Because the husk is still moist, the nut inside stays protected while it ripens underground.
 
So when a squirrel eats green walnuts, it’s also planning ahead for winter.
 

How Squirrels Eat Green Walnuts

Watching a squirrel eat green walnuts is a little messy, but it’s a fascinating process to observe.
 

1. They Strip the Husks First

Squirrels usually peel away the green outer husk before getting to the shell.
 
They’ll nibble and tear at the husk until the hard shell underneath is exposed.
 
If you find shredded green husks under a walnut tree, that’s a clear sign squirrels have been eating green walnuts nearby.
 

2. They Crack the Shell with Their Teeth

Once the husk is gone, squirrels use their strong incisors to crack the shell.
 
This takes some effort because walnut shells are hard, but squirrels are built for the job.
 
After cracking it open, they pull out the kernel and eat it quickly.
 

3. They Sometimes Eat Them Whole

Sometimes squirrels eat green walnuts almost whole, especially when the nut is still soft.
 
Young green walnuts haven’t hardened completely, so a squirrel can chew through the entire thing.
 
That’s why you might see a squirrel munching on what looks like an entire green ball.
 

4. They Cache More Than They Eat

Squirrels don’t just eat green walnuts on the spot.
 
They often carry them off and bury them in scattered spots around the yard.
 
This caching habit is why so many walnut trees seem to pop up in random places.
 

Do Squirrels Eating Green Walnuts Harm Your Trees?

If you have walnut trees, you might wonder whether squirrels eating green walnuts is a problem.
 

1. They Reduce Your Harvest

The biggest issue is that squirrels eat green walnuts before they ripen.
 
That means fewer nuts for you to gather when fall arrives.
 
If a squirrel population is high, you might lose a large portion of your crop.
 

2. They Can Damage Branches

Squirrels climb out onto thin branches to reach green walnuts, and sometimes those branches break under their weight.
 
This isn’t usually serious, but heavy activity can cause minor damage over time.
 

3. They Help Plant New Trees

On the flip side, squirrels that eat green walnuts also help spread walnut trees.
 
When they forget where they buried a nut, it can sprout into a new tree.
 
So their habit isn’t all bad, especially if you don’t mind a few extra trees.
 

4. They Rarely Strip a Tree Completely

Squirrels eat green walnuts steadily, but they rarely take every single one.
 
Most trees still produce enough nuts to drop in autumn.
 
So unless you’re counting every walnut, the damage is usually manageable.
 

So, Do Squirrels Eat Green Walnuts?

Squirrels do eat green walnuts, and they do it for good reasons like nutrition, timing, and storage.
 
They strip the husks, crack the shells, and sometimes bury the nuts for later.
 
While this can cut into your walnut harvest, it’s also part of how squirrels survive and how walnut trees spread.
 
So the next time you see a squirrel nibbling on a green walnut, you’ll know exactly what’s going on and why it matters.
