Which Animals Eat Peanuts: Which Wildlife to Feed and How to Do It Safely
Whether you enjoy watching wildlife from your window, using it as a learning experience for your family, or providing supplemental feeding during harsh winters, feeding backyard wildlife is a hobby shared by many. However, knowing what to feed different species and how to feed them are two equally important factors.
Spoiler: There are a number of animals that eat peanuts, making it one of the most versatile feeding options.
From birds to squirrels and beyond, a wide range of species enjoy this food source. Keep reading to learn which animals eat peanuts, species-specific tips, and safety guidance.
Which Animals Eat Peanuts: A Wildlife Species Guide
So which animals like peanuts?
Peanuts are consumed by a wide range of wild animals, including birds, rodents, and larger mammals. And while there are a number of animals that eat peanuts, it’s important to consider factors such as which species prefer in-shell versus shelled peanuts, which ones you should feed, and how they interact with peanuts in controlled feeding environments compared to the wild.
Below, we provide a species-by-species breakdown to help you turn your backyard into a safe feeding space. And for more general guidance outside of peanuts, check out our wildlife and bird feeding guide.
Which Birds Eat Peanuts: Species, Preferences, and Feeder Tips
Birds are among the most consistent peanut consumers across species. However, the type of peanut and feeder you use determines which birds you attract, so let’s take a closer look.
1. Peanut-Eating Birds: Jays, Woodpeckers, and Nuthatches
Which birds like peanuts?
There are multiple bird species that actively seek out peanuts, including:
- Blue Jays
- Woodpeckers (Downy, Hairy, Red-bellied)
- White-breasted Nuthatch
- Chickadees
We should note that while there are many peanut-eating birds, habitat and regional variation play a big role in what you may see in your backyard.
2. Are Peanuts Good for Birds? Nutrition, Safety, and What to Avoid
Many wonder, are peanuts safe for birds?
Put simply, yes.
Peanuts are widely considered a nutritious food for a range of bird species. They're naturally high in fat and protein, making them a great energy source for daily activities. This is especially important during harsh winters, helping birds withstand extreme weather conditions and limited food availability.
However, not all types of peanuts are recommended. While raw and roasted peanuts are safe for birds, salted peanuts should always be avoided. This is because birds cannot process high levels of sodium, which can potentially cause kidney damage.
The other thing you should watch out for is stale or moldy peanuts, as they present highly toxic aflatoxin risks to birds. You can avoid this by purchasing high-quality, fresh peanuts and storing them in a cool, dry place to prevent mold growth.
3. Do Birds Like In-Shell or Shelled Peanuts More?
As a general rule of thumb, in-shell peanuts are recommended for birds with strong bills, such as blue jays, woodpeckers, chickadees, and titmice. You must choose the right feeder for in-shell peanuts for birds and squirrels, such as specialized large-mesh or cage feeders.
Birds such as cardinals and mockingbirds, on the other hand, prefer out-of-shell peanuts, which can be placed in standard feeders.
Should You Feed Squirrels Peanuts? Safety and Feeder Tips
Squirrels and peanuts are often associated with one another, making them a popular feeding choice. What many don’t realize, however, is that feeding habits are critical to ensuring their safety.
Here’s what you should know:
1. Are Peanuts Safe for Squirrels? What to Know Before You Feed
The big question is, should you feed squirrels peanuts?
The answer to this isn’t as straightforward as it is for birds. While squirrels are enthusiastic peanut eaters, it’s generally considered that peanuts shouldn’t make up their primary food source. This is because raw peanuts contain a trypsin inhibitor, which can interfere with protein digestion and potentially impact their health.
But don’t worry, this doesn’t mean these creatures can’t enjoy peanuts as a snack. Choosing high-quality peanuts and being cautious with portion sizes, such as only giving them a couple of peanuts at a time, can not only support their nutrition but also help attract more squirrels to your yard.
2. Managing Squirrels at Bird Feeders
There are multiple strategies people use to keep squirrels away from bird feeders, such as placing them out of reach. For instance, you can string a line between two trees and position the feeder high up where they can’t easily access it.
We also recommend cleaning up any fallen seeds and peanuts, as this can attract squirrels.
But if you ask us our favorite tip, we’d suggest creating a separate feeding space just for squirrels. This helps keep them away from bird feeders, and by using Old Potters wildlife peanuts, you create a natural, mess-free way to draw squirrels to their own area.
Other Animals That Eat Peanuts: Mammals, Foragers, and Opportunists
Curious about which animals eat peanuts beyond birds and squirrels?
Peanuts appeal to a wider range of animals than most people expect. Below is a quick guide to which animals you can safely feed (and which you should avoid feeding).
1. Raccoons, Deer, and Opossums: Wildlife That Like Peanuts but Should Not Be Fed
There are many animals that like peanuts, but that doesn’t mean they should be fed them.
While opportunistic animals such as raccoons, opossums, and deer would love a surprise snack, intentionally feeding these species can lead to habituation, increase the risk of human-wildlife conflict, and may even breach local regulations.
2. Chipmunks: Small Animals That Eat Peanuts and Cache Them
Chipmunks are natural peanut foragers, so feel free to give them a treat if you have the opportunity.
While they enjoy both types of peanuts, in-shell peanuts are preferred, as they can store them more easily, helping protect against moisture and encouraging their natural behavior of cracking open shells.
Ground-level feeding is also ideal compared to elevated feeders, as it better reflects their natural scavenging behavior.
Are Peanuts Safe for Wildlife? How to Feed the Right Way
Peanuts are safe for most wildlife when chosen and stored correctly, but the wrong type or poorly stored peanuts can pose real health risks. Use this section as a practical safety checklist to help ensure every animal you feed stays safe and healthy.
1. Raw, Roasted, or Salted: Which Peanuts Are Safe for Birds and Squirrels
If you’re still wondering, “are peanuts safe for birds?” and “are peanuts safe for squirrels?” here’s a quick summary to guide you:
- Salted peanuts should always be avoided, as they can pose a risk of sodium toxicity in small animals and birds.
- Unsalted, dry-roasted and raw peanuts are generally safe for peanut-eating birds and animals.
Whether you’re interested in shelled or in-shell peanuts, remember that quality matters. Old Potters peanuts are non-GMO and US-grown, helping you support the health of your backyard visitors.
2. Feeder Types That Work for Peanut-Eating Birds and Mammals
Choosing the right feeder helps attract specific wildlife while keeping feeding areas more organized.
- Mesh tube feeders: Best for clinging birds like woodpeckers and chickadees. Use peanuts to provide a high-energy, easy-access food source.
- Tray feeders: Ideal for larger ground birds and squirrels. Place in open areas for easy access and visibility.
- Scatter feeding: Works well for chipmunks and ground-feeding birds like doves. Scatter small amounts to encourage natural foraging.
For more detailed setup tips, refer to the wildlife and bird feeding guide.
3. Storage, Freshness, and Aflatoxin: The Safety Risk Most Feeders Miss
When it comes to feeding wildlife, safety is absolutely critical. One of the biggest risks is aflatoxin, a naturally occurring mycotoxin that can be harmful to birds and mammals.
Since this can be caused by moldy or stale peanuts, here are three tips to help keep your backyard visitors safe:
Tip #1: Buy in Smaller Quantities
While it may be tempting to stock up, buying too much at once can cause peanuts to become stale or spoil. Purchasing smaller quantities helps ensure they stay fresh and safer to consume.
Tip #2: Store Safely & Discard Old Peanuts
Store peanuts in a cool, dry place to prevent mold growth. We also recommend removing uneaten peanuts after 2–3 days, especially in wet weather, to reduce contamination risk.
Tip #3: Only Purchase High-Quality Peanuts
Choosing high-quality, carefully sourced peanuts reduces the risk of contamination from the start. Old Potters wildlife peanuts offer a reliable option for feeding wildlife safely.
