Will Crows Eat Walnuts

Crows will eat walnuts, and they actually love them.
 
If you’ve ever watched a murder of crows descend on a walnut tree, you already know how quickly they can clean it out.
 
These clever birds have figured out that walnuts are packed with fat, protein, and calories—everything a crow needs to thrive.
 
So yes, crows will eat walnuts, and they’ll do it with surprising skill and enthusiasm.
 
In this post, we’ll explore why crows eat walnuts, how they crack them open without hands, and whether you should worry about crows eating walnuts from your own trees.
 
Let’s get into it.
 

Why Crows Eat Walnuts

Crows will eat walnuts for the same reason humans do—they’re nutritious and energy-dense.
 
Here’s why walnuts are such an attractive food source for crows:
 

1. Walnuts Are Packed With Healthy Fats

Walnuts contain high levels of omega-3 fatty acids, which give crows a massive energy boost.
 
For a bird that flies miles every day and needs to stay warm through cold nights, that fat content is gold.
 
This is a big reason why crows will eat walnuts whenever they find them.
 

2. They Offer Serious Calories

A single walnut can contain over 150 calories, which is a lot for a bird that weighs less than a pound.
 
Crows need roughly 100 to 150 calories per day, so one or two walnuts can cover a huge chunk of their daily needs.
 
That efficiency is why crows eat walnuts so eagerly when they’re available.
 

3. Crows Are Opportunistic Omnivores

Crows eat almost anything—insects, seeds, fruit, carrion, garbage, and yes, walnuts.
 
They’re not picky eaters, and they’re smart enough to recognize walnuts as a high-value food source.
 
So if there’s a walnut tree nearby, crows will eat walnuts from it regularly.
 

How Crows Eat Walnuts

Here’s where things get really interesting.
 
Crows don’t have hands, so getting through a hard walnut shell isn’t easy.
 
But crows will eat walnuts anyway, and they’ve developed some clever tricks to do it.
 

1. They Drop Them From Great Heights

A common method crows use to eat walnuts is dropping them onto hard surfaces like roads, driveways, and rocks.
 
This is why crows will eat walnuts by flying high, releasing the nut, and swooping down to check if it cracked.
 
If it didn’t break, they’ll grab it and try again from a higher altitude.
 

2. They Use Roads and Cars

Some crows have learned to drop walnuts onto busy roads so passing cars crack the shells for them.
 
Then they wait for traffic to clear before swooping in to collect the nut meat.
 
This behavior shows just how intelligent crows are—and how determined they are to eat walnuts.
 

3. They Tuck Walnuts Into Cracks

Another technique crows use to eat walnuts is wedging them into cracks in tree bark, rocks, or pavement.
 
Once the walnut is stuck in place, they peck at it until the shell weakens and breaks apart.
 
This is a smart way crows eat walnuts without needing to drop them repeatedly.
 

4. They Cache Walnuts for Later

Crows don’t always eat walnuts on the spot—they often bury or stash them for future meals.
 
This is called caching, and it’s a survival strategy that helps crows eat walnuts during leaner times.
 
They’ll remember the locations of hundreds of cached walnuts, which is seriously impressive memory work.
 

Are Walnuts Safe for Crows?

Walnuts are safe for crows to eat, but there are a few things to keep in mind.
 

1. Raw Walnuts Are Best

Raw, unsalted walnuts are the healthiest option for crows.
 
Salted or roasted walnuts can contain too much sodium, which isn’t good for birds.
 
So if you’re feeding crows walnuts on purpose, stick to the plain, raw kind.
 

2. Watch Out for Moldy Walnuts

Moldy walnuts can contain aflatoxins, which are toxic to birds.
 
If you find old walnuts on the ground that look black or fuzzy, don’t offer them to crows.
 
Fresh walnuts are always the safer choice when it comes to feeding crows walnuts.
 

3. Avoid Flavored or Candied Walnuts

Walnuts coated in sugar, honey, or spices aren’t good for crows.
 
These additives can cause digestive issues and offer no real nutritional benefit.
 
So keep it simple—crows will eat walnuts just fine without any extras.
 

4. Moderation Matters

Even though crows will eat walnuts happily, they shouldn’t live on them alone.
 
Crows need a varied diet to stay healthy, so walnuts should be a treat, not the main course.
 
If you’re feeding wild crows, mix walnuts with other crow-friendly foods like unsalted peanuts, oats, or fruit.
 

Will Crows Eat Walnuts From Your Trees?

If you have a walnut tree in your yard, you’ve probably noticed crows eyeing it.
 
Crows will eat walnuts straight from the tree once they’re ripe, and they’ll also grab them off the ground.
 
A single crow can carry off several walnuts at a time, stuffing them in their throat pouch and even under their tongue.
 
It’s fascinating to watch, but if you’re growing walnuts for yourself, it can be frustrating.
 
To protect your harvest, you can net the tree or harvest walnuts as soon as they ripen.
 
You can also try hanging shiny objects or reflective tape to scare crows away.
 
Just know that crows are smart—they’ll figure out most deterrents eventually.
 

Do All Crows Eat Walnuts?

Not every crow has access to walnuts, but if they do, they’ll eat them.
 
Different species like the American Crow, Fish Crow, and Common Raven all eat walnuts when they come across them.
 
Even urban crows will eat walnuts, especially in parks where walnut trees grow.
 
So whether you’re in the countryside or the city, if there are walnuts and crows around, there’s a good chance crows will eat walnuts there too.
 

So, Will Crows Eat Walnuts?

Crows will eat walnuts, and they’ll go to impressive lengths to crack them open.
 
From dropping them on roads to caching them for winter, crows have turned walnut-eating into an art form.
 
Walnuts are a healthy, calorie-rich food for crows, as long as they’re raw and free of mold.
 
So whether you’re watching crows raid a walnut tree or you’re thinking about leaving a few out for your local flock, now you know the answer.
 
Crows will eat walnuts, and honestly, they’re pretty good at it.
