Squirrels are among the most common wildlife seen in urban parks and suburban backyards, delighting many with their playful antics and bushy tails. One question that often arises is: what nuts do squirrels eat? This article will explore the nutty preferences of these agile rodents, examining their diet, behavior, and the impact of various nut types on squirrel health.

Common Nuts in a Squirrel's Diet

Squirrels are omnivorous, meaning they eat both plant and animal matter, but their preference leans heavily toward plant-based foods, especially nuts. Here are some of the most common nuts that squirrels eat:

1. Walnuts

Walnuts are a favorite among squirrels due to their high-fat content and rich flavor. Both English walnuts and black walnuts are consumed, though the hard shell of black walnuts can be more challenging to crack.

2. Acorns

Acorns are another primary food source, particularly for tree squirrels. They are the nuts of oak trees and come in various species, each offering different nutritional benefits. Squirrels often gather acorns in the fall and store them for winter use.

3. Pine Nuts

Pine nuts, found within pine cones, are a significant food source for squirrels, especially in pine-rich habitats. They are packed with healthy fats and proteins, making them an essential part of a squirrel's diet.

4. Hazelnuts

Hazelnuts are highly nutritious and often eaten whole by squirrels. They prefer fresh nuts but will also consume those that have fallen to the ground.

5. Chestnuts

While chestnuts are not as common as the previous nuts mentioned, squirrels will eat them when available. Their softer shells make them easier to access and enjoy.

Squirrel Nut Behavior and Foraging

Squirrels have developed specific foraging behaviors to maximize their chances of finding nuts. They are known to bury nuts (a behavior called "caching") for later consumption. Studies have shown that they have excellent spatial memory, which allows them to locate buried nuts even after long periods.

Example: Caching Behavior

For instance, a study published in the journal Animal Behavior found that eastern gray squirrels exhibited sophisticated caching behaviors by varying the locations and types of nuts buried. This not only helps them to store food but also discourages theft from other animals.

Nutritional Value of Nuts for Squirrels

Nuts are crucial for squirrels, providing the necessary calories and nutrients for their active lifestyle. They are high in proteins, healthy fats, and essential vitamins, promoting overall health and vitality. However, not all nuts are created equal; some are more beneficial than others.

Important Consideration: Nutrient Balance

While nuts are a valuable food source, a diet composed solely of nuts can lead to imbalances. For example, too many fatty nuts without the necessary fibers from fruits or vegetables may lead to obesity in squirrels. Therefore, it's essential to ensure they have a varied diet.

Practical Tips for Backyard Squirrel Watching

If you want to attract squirrels to your backyard, consider providing a mix of their favorite nuts. Here are some practical tips:

Nut Mix: Offer a combination of unsalted walnuts, hazelnuts, and peanuts (while peanuts are technically legumes, squirrels enjoy them).
Nut Feeders: Install squirrel feeders designed specifically for nuts, which can help keep them safe from predators while feeding.
Safety First: Avoid processed nuts with salt, sugar, or other additives that can be harmful to squirrels.

Conclusion

Understanding what nuts squirrels eat enhances our appreciation for these fascinating creatures and informs how we can coexist with them in our backyards. By providing appropriate foods and observing their behavior, we can ensure a healthy environment for squirrels while enjoying their lively presence.
