Walnuts, on the other hand, are a bit more challenging for squirrels to handle. The hard shells of walnuts require more effort to crack open compared to the softer shells of peanuts. However, the reward is worth the extra work. Walnuts are exceptionally rich in healthy fats, protein, and essential nutrients, making them a nutritious choice for squirrels.

Squirrels do indeed enjoy walnuts, and they are known to cache them for later consumption. In the process of breaking open walnut shells can help keep a squirrel’s teeth healthy by wearing them down.

Entertainment and Education: Feeding squirrels can hours of entertainment and educational opportunities, especially for children and nature enthusiasts. Observing squirrels up close can help individuals learn more about their behaviors, diet, and interactions.

Supplemental Nutrition: In urban and suburban areas, where natural food sources may be limited or impacted by human activities, squirrels with nuts can offer them nutrition. Nuts are calorie-dense and can help squirrels meet their energy requirements.

While raw peanuts are a common and popular choice for feeding squirrels, they can be problematic when consumed in excess. Raw peanuts often contain a natural toxin called aflatoxin, which can be harmful to both squirrels and humans. Aflatoxin can lead to liver damage and other health issues. Roasting or boiling peanuts can reduce aflatoxin levels, making them safer for consumption.

Moldy nuts, including moldy peanuts, walnuts, or other nut varieties, can be toxic to squirrels. Mold produces mycotoxins that can be harmful when ingested. Squirrels may accidentally consume moldy nuts if they are left out for extended periods or exposed to moisture. It’s fresh and uncontaminated nuts to squirrels.

Some tree nuts, like horse chestnuts (also known as conkers), are not safe for squirrels to eat. These nuts contain compounds called saponins and glycosides, which are toxic to both humans and animals. Ingesting horse chestnuts can lead to gastrointestinal distress and other health issues in squirrels.

Why are squirrels obsessed with nuts?

They’ll even pick out a favorite tree, and eat mostly from that one. In general, red squirrels would rather eat hazelnuts than, say, the seeds of spruce cones.

Nutritional Value: Nuts are a highly nutritious food source, rich in essential nutrients like fats, proteins, and carbohydrates. Squirrels are small mammals with high metabolic rates, and they require a substantial amount of energy to maintain their active lifestyles. Nuts them with the calorie-dense energy they need, particularly during the demanding winter months when other food sources are scarce.

Storage for Winter: Squirrels are well-known for their habit of caching nuts. They bury or hide nuts in various locations throughout their territories, creating a reserve of food to sustain them through the winter. This storage behavior is driven by the instinct to ensure a steady food supply when resources become scarce. Their ability to and locate these hidden caches is a testament to their impressive spatial memory.

Diverse Diet: While nuts are a significant part of a squirrel’s diet, they are not the sole food source. Squirrels are opportunistic feeders and have a diverse diet that includes fruits, vegetables, fungi, insects, and even bird eggs. Nuts are just one component of their overall nutritional intake, and they adjust their diet based on what is available seasonally.

Can squirrels eat bread?

Bread products contain very little nutritional value for wildlife. In fact, they can be full of sugars, sodium and carbohydrates. Sadly, these ingredients can be deadly to birds, squirrels, fish and many other animals that are not equipped to digest this unnatural diet.

Bread is not a nutritionally complete food for squirrels. It lacks the essential proteins and fats that are crucial for their overall health. A diet solely or predominantly consisting of bread can lead to nutritional deficiencies. Bread is often low in fiber, and a diet high in low-fiber foods like bread can cause digestive problems for squirrels. 

It may lead to constipation or other gastrointestinal issues. Bread is calorie-dense, and squirrels that consume excessive amounts of bread can become overweight or obese. Obesity in squirrels can have adverse health effects and reduce their overall fitness. Feeding squirrels large quantities of bread can lead to them relying on human food sources and neglecting their natural foraging behaviors. 

This dependency on human handouts can hinder their ability to find and consume a balanced and diverse diet in the wild. The nutritional quality of bread can vary widely.

Lactose Intolerance: Like many mammals, squirrels are lactose intolerant. Lactose is the sugar found in milk, and to digest it properly, an enzyme called lactase is required. Squirrels, like most adult mammals, typically produce very little or no lactase after weaning. Consuming milk or dairy products can lead to digestive discomfort, including diarrhea and abdominal cramps.

Natural Diet: Squirrels have evolved to obtain their nutrients from plant-based sources. Their digestive systems are well-suited for breaking down plant materials like nuts and seeds, not animal-derived products like milk.

Lack of Access: In their natural habitats, squirrels do not have access to milk. They are wild animals that forage for their food in the environment, and they have not evolved to seek out or consume milk.

The dietary preferences of squirrels, particularly their affinity for nuts, offer us a captivating glimpse into the intricate world of these small yet remarkable creatures. Through that squirrels consume a diverse array of nuts, including acorns, hickory nuts, walnuts, and more, depending on their geographical location and seasonal availability. Nuts serve as a vital source of squirrels energy and nutrients for squirrels, helping them survive harsh winters and thrive in various habitats. Squirrels’ unique behaviors related to nuts, such as caching and burying them for later consumption, highlight their exceptional cognitive abilities and adaptability. 

These behaviors not only ensure their survival during lean times but also inadvertently contribute to forest regeneration by occasionally forgetting or failing to retrieve some of their buried nuts, allowing them to sprout and grow into new trees. Moreover, the interaction between squirrels and their nut-based diet has ecological implications. Squirrels act as seed dispersers, aiding in the distribution of tree seeds across forests. In doing so, they play a crucial role in maintaining the biodiversity and health of their ecosystems. 

The relationship between squirrels and nuts is a testament to the interconnectedness of species within natural environments.
