Introduction
Squirrels, those bushy-tailed acrobats of our backyards and parks, hold a special place in our collective imagination. We picture them burying nuts with frantic determination, their cheeks bulging with their precious cargo. While the image of a squirrel and a nut is iconic, the reality of their diet is far more diverse and fascinating than many realize. Understanding what makes up a squirrel’s favorite food is not only interesting but also essential for anyone looking to coexist peacefully, offer supplemental feeding responsibly, or simply appreciate these resourceful creatures.
While nuts are indeed a cornerstone of their nutrition, the culinary world of a squirrel extends far beyond the confines of a single food group. Their palate is influenced by seasonality, geographical location, and, most importantly, availability. Seeds, fruits, and even, on occasion, insects find their way into the squirrel’s varied diet. So, let’s embark on a nutty adventure to uncover the ultimate guide to a squirrel’s favorite feast.
The Classic Favorite Nuts
The unwavering affection squirrels have for nuts is well-deserved. Nuts are a nutritional powerhouse, packed with essential fats and proteins vital for a squirrel’s energy needs, particularly during the colder months when survival depends on stored reserves. The high fat content provides sustained energy, while the protein aids in muscle development and overall health.
Types of Nuts Squirrels Love
Among the vast selection of nuts available in nature, a few varieties stand out as squirrel favorites. Acorns, the fruit of the oak tree, are a cornerstone of many squirrel diets, especially for those residing in oak-rich environments. Different types of acorns, such as those from white oak versus red oak trees, offer varying levels of tannins. Tannins are bitter compounds that can be unpalatable, so squirrels have learned to preferentially select acorns with lower tannin levels or bury them for extended periods, allowing the tannins to leach out. This caching behavior demonstrates a remarkable level of foresight and adaptability.
Walnuts, with their rich flavor and high nutritional content, are another sought-after prize. However, their thick shells present a challenge. Squirrels have evolved powerful jaws and teeth to crack open these stubborn nuts, displaying impressive persistence and determination.
Hazelnuts, smaller and easier to manage than walnuts, are also readily cached by squirrels. Their relatively thin shells make them a convenient food source, and their abundance in certain areas makes them a staple of the local squirrel population’s diet.
Pecans, another delicious and nutritious option, are particularly favored in regions where pecan trees are prevalent. These nuts are relatively easy to crack open, making them a valuable food source for squirrels. They provide a high-fat, high-calorie meal that’s especially important for building up winter reserves.
Even beechnuts can be an alternative food source for squirrels during times of scarcity. While perhaps not their first choice, squirrels demonstrate their opportunistic nature by consuming these nuts when other options are limited.
How Squirrels Store Nuts
The process of caching, or burying nuts, is an integral part of squirrel behavior. Squirrels are notorious for their impressive spatial memory, allowing them to remember the location of hundreds, even thousands, of buried nuts. This behavior is crucial for surviving the winter months when fresh food sources are scarce. They dig shallow holes, carefully place the nut inside, and then meticulously cover it up, often disguising the location to deter other squirrels or animals from stealing their treasure.

Beyond Nuts Other Squirrel Food Categories
Seeds
While nuts may reign supreme in the squirrel’s culinary hierarchy, their diet extends far beyond these hard-shelled delicacies. A variety of seeds, fruits, vegetables, and even the occasional insect contribute to a well-rounded and balanced nutritional intake.
Sunflower Seeds
Sunflower seeds, a common sight in bird feeders, are a readily available and popular food source for squirrels. They are rich in oil and provide a quick energy boost. Squirrels can easily crack open the shells to access the nutritious seed inside, making them a convenient and appealing food option.
Pumpkin Seeds
Pumpkin seeds, particularly during the autumn season, offer a seasonal treat for squirrels. Whether pilfered from discarded pumpkins or intentionally offered as a supplement, these seeds provide a good source of nutrients and are generally well-received by squirrels.
Other Seed Varieties
Many other seed varieties, from the seeds of pine cones to those found in various plants and flowers, contribute to the squirrel’s diverse diet. They’re opportunistic eaters, and they will take advantage of whatever seeds are available in their environment.
Fruits & Vegetables
Fruits and vegetables also play an important role in the squirrel’s nutritional intake. Berries, both wild and cultivated, are a favorite, providing essential vitamins and antioxidants. Squirrels will happily forage for berries in gardens or natural areas.
Apples
Apples, readily available in many regions, are another common and enjoyed fruit for squirrels. They provide a source of sugar and hydration, particularly during warmer months.
Grapes
Grapes, with their sweet and juicy flesh, are another delightful treat for squirrels. Whether found growing wild or in vineyards, grapes offer a refreshing and energy-rich food source.
Corn
Corn, particularly in areas where it’s grown for agriculture, can be a significant part of the squirrel’s diet. They may raid cornfields or gardens to access this readily available food source.
Other Fruits/Vegetables
Many other fruits and vegetables, depending on their availability and the squirrel’s individual preferences, may also find their way into their diet. They’re opportunistic feeders and will sample a variety of plant-based foods.
Flowers, Buds, and Shoots
During the spring, when new growth is abundant, squirrels often feed on flowers, buds, and shoots. These tender plant parts provide essential nutrients and moisture as the squirrels emerge from the winter months. This dietary shift reflects the changing seasons and the availability of different food sources.
Insects & Fungi (The Unexpected)
While often overlooked, insects can provide an occasional source of protein for squirrels. Particularly during breeding season or when other food sources are scarce, squirrels may supplement their diet with insects, larvae, or even small invertebrates. This is not a primary food source, but it demonstrates the squirrel’s adaptability and opportunistic nature.
Mushrooms
Some squirrels may even consume certain types of fungi or mushrooms. It is important to be careful if you are feeding squirrels, as some mushrooms are toxic, and they may harm or even kill the squirrels.
Food Scarcity
During times of food scarcity, squirrels will broaden their diet even further, consuming foods they might typically avoid. This might include tree bark, roots, or even scraps of food left by humans. This adaptability is essential for their survival in challenging environments.
Regional Variations and Seasonal Changes
Location Matters
A squirrel’s diet is not a fixed menu. It’s a dynamic and adaptable feast, influenced by both location and the changing seasons. Geographic location plays a significant role in determining the types of food available to squirrels. Coastal squirrels, for example, may supplement their diet with shellfish or crustaceans, taking advantage of the marine resources available in their environment. Squirrels in forested areas will have access to a wider variety of nuts and seeds, while those in urban environments may rely more heavily on human-provided food sources.
Seasonal Shifts
Seasonal changes also dictate the squirrel’s dietary habits. In the fall, they focus on caching nuts and seeds to prepare for winter. In the spring, they may feed on flowers, buds, and shoots as new growth emerges. During the summer months, they have access to a wider variety of fruits, vegetables, and insects. These seasonal shifts ensure that squirrels can adapt to the changing availability of food resources throughout the year.
Feeding Squirrels Dos and Don’ts
The question of whether to feed squirrels is a complex one, with both potential benefits and drawbacks.
On the one hand, providing supplemental food can help squirrels survive during periods of scarcity, especially during harsh winters. On the other hand, feeding squirrels can lead to dependency, attract other animals, and disrupt their natural foraging behaviors.
If you choose to feed squirrels, it’s important to do so responsibly. Offer safe and nutritious foods, such as unsalted nuts, seeds, and small pieces of fruit or vegetables. Avoid feeding them processed foods, salty snacks, chocolate, or artificial sweeteners, as these can be harmful to their health. Dairy, too, is generally not recommended.
Providing a source of fresh water is also essential, especially during dry periods. A shallow dish or birdbath can provide squirrels with a much-needed source of hydration.
Conclusion
The culinary world of a squirrel is far more diverse and fascinating than many realize. While nuts are undoubtedly a cornerstone of their diet, they also rely on a wide variety of seeds, fruits, vegetables, and even the occasional insect to meet their nutritional needs. Their diet is influenced by seasonality, geographical location, and the availability of different food resources.
