Did you know that squirrels, those cute little creatures that we often see scurrying around our backyards, are actually opportunistic eaters? Yes, it’s true! Squirrels are omnivores, which means they eat a wide variety of foods, including baby birds. When squirrels are hungry and the opportunity arises, they may feast on baby birds or even their eggs. Some squirrel species, like the American Red Squirrel, are known to be more aggressive and likely to prey on these helpless little birds. While birds do their best to defend their nests against predators, unattended nests become vulnerable to squirrel attacks. It’s a tough world out there for baby birds, with many threats, including squirrels and other predators like blue jays, crows, raccoons, opossums, and snakes. Their journey to adulthood is filled with challenges, but they always strive to overcome and thrive in the face of adversity.

Squirrels as Omnivores

Squirrels are fascinating creatures that display a diverse range of eating habits. While they are commonly known for their love of nuts, they are actually omnivores and consume a variety of foods. This includes baby birds, which may come as a surprise to some. These small mammals have a versatile diet that allows them to adapt to different food sources depending on availability and need.

Squirrel Diet

In order to understand why squirrels sometimes eat baby birds, it is important to first examine their dietary preferences. Nuts and fruits are typically the primary components of a squirrel’s diet. They have specialized teeth that allow them to gnaw through the hard shells of nuts, such as acorns, walnuts, and hickory nuts. This is why we often see squirrels scurrying up trees, gathering and storing these food items for later consumption.

Additionally, squirrels have a special fondness for fruits. Apples, berries, and even the occasional slice of watermelon are enticing to these foragers. Their sharp incisors enable them to easily break through the skins of fruits, allowing them to enjoy the juicy goodness within. This preference for nuts and fruits provides them with a rich source of carbohydrates, proteins, and fats essential for their survival.

Variety of Foods

However, squirrels are not limited to a nutty and fruity diet. They are opportunistic eaters and will consume whatever food sources are available to them. This includes insects, grubs, small vertebrates, and even bird eggs. Squirrels possess the ability to adapt their dietary preferences based on the circumstances they find themselves in. This flexibility allows them to survive in various habitats and climates, making them highly adaptable creatures.

Conditions for Eating Baby Birds

While it may seem surprising that squirrels would target baby birds as a food source, there are specific conditions that must be met for this behavior to occur.

Hungry Squirrels

Like any organism, squirrels have basic survival needs that must be met. When food sources are scarce or competition is high, squirrels may find themselves in a state of hunger. In these situations, their instincts kick in and they become more opportunistic hunters. This hunger-driven behavior is what prompts them to seek out alternative food sources, such as baby birds.

Opportunity to Eat Baby Birds

Another condition that must be present for squirrels to eat baby birds is the opportunity to do so. Squirrels are skilled climbers and can easily maneuver through tree branches to access nests. If they come across an unattended nest with vulnerable baby birds, they may seize the opportunity to satisfy their hunger. It is important to note that squirrels do not actively search for baby birds to prey upon, but rather take advantage of situations that present themselves.

Aggressive Squirrel Species

Not all squirrel species display the same level of aggression when it comes to consuming baby birds. One species that is particularly known for its aggressive behavior is the American Red Squirrel.

American Red Squirrel

The American Red Squirrel, also known as the Pine Squirrel, is a small species of squirrel that inhabits coniferous forests in North America. Despite their small size, they are renowned for their territorial nature and aggressive behavior towards other animals, including birds. These squirrels have been observed attacking and even killing baby birds when the opportunity arises.

Due to their territorial nature, American Red Squirrels fiercely defend their food caches and nesting sites. This defensive behavior extends to protecting their territory from intruding birds. If a nest is located within their territory, they may see the baby birds as potential threats to their resources and act accordingly to eliminate them.

Likelihood of Eating Baby Birds

While the American Red Squirrel is known to display aggression towards baby birds, it is important to note that not all individuals of this species exhibit the same behavior. The likelihood of a squirrel eating baby birds varies depending on various factors, including the availability of other food sources and the level of competition for those resources. Therefore, while some American Red Squirrels may engage in this behavior, it is not a universal trait among all individuals of the species.

Squirrels and Bird Eggs

In addition to baby birds, squirrels also consume unattended bird eggs when the opportunity presents itself. This behavior is a result of their natural instincts and the vulnerability of unattended nests.

Eating Unattended Eggs

Squirrels are opportunistic feeders and will take advantage of unattended nests to obtain a quick and easy meal. If a bird has temporarily left its nest, a squirrel may seize the opportunity to consume the unattended eggs. Their dexterity and climbing skills enable them to reach the nests hidden within branches and foliage.

Vulnerability of Unattended Nests

Birds typically display strong instincts to defend their nests against potential predators. They actively protect their eggs or young by vocalizing warning calls and engaging in aggressive behaviors. However, when a nest is left unattended, its vulnerability increases significantly. Squirrels, with their agility and ability to navigate trees effortlessly, can exploit these unattended nests and consume the eggs within.

It is worth noting that squirrels do not actively seek out bird eggs to eat but rather come across unattended nests during their foraging escapades. Their opportunistic nature drives them to take advantage of such situations for their own survival.

Scarcity of Food Sources

One of the reasons why squirrels may resort to eating baby birds and eggs is the scarcity of their typical food sources. Nuts and fruits are the primary components of a squirrel’s diet, but these resources may become scarce due to various factors.

Nuts and Fruits as Primary Food

Nuts and fruits provide squirrels with a rich source of nutrients needed for their survival. However, the availability of these food sources fluctuates throughout the year. In fall, when nuts are abundant, squirrels actively collect and store them for the leaner winter months. Similarly, fruits are abundant during certain seasons but scarce during others. When these primary food sources become limited, squirrels must find alternative options to sustain themselves.

Turning to Baby Birds and Eggs

When the usual sources of food become scarce, squirrels may turn to alternative food sources, such as baby birds and eggs. While this behavior may seem unusual, it is a survival instinct that allows squirrels to adapt to their environment and ensure their own wellbeing.

It is important to note that the consumption of baby birds and eggs is not a preferred or habitual behavior for squirrels. They possess natural adaptations and instincts that enable them to exploit various food sources, but they primarily rely on their preferred sources of nuts and fruits for their nutritional needs.

Other Predators of Baby Birds

While squirrels are known to consume baby birds and eggs, they are not the only predators that pose a threat to these vulnerable creatures.

Blue Jays

Blue Jays are highly intelligent birds known for their bold and assertive behavior. They are opportunistic feeders and have been observed raiding the nests of other birds, including those with baby birds or eggs. These clever birds can be a significant threat to the survival of young chicks, especially when food resources are limited.


Crows are large, highly adaptable birds that are known for their curiosity and problem-solving abilities. They have been observed raiding nests and consuming baby birds and eggs. These resourceful creatures are skilled hunters and can pose a significant threat to the survival of baby birds.


Raccoons are opportunistic omnivores that will readily consume baby birds and eggs when given the chance. These nocturnal mammals have dexterous forelimbs that enable them to manipulate objects and gain access to otherwise protected nests. Their adaptability and scavenging skills make them formidable predators to baby birds.


Opossums, often misunderstood creatures, are also opportunistic predators of baby birds and eggs. These nocturnal marsupials have sharp teeth and claws that allow them to climb trees and access nests. They possess a diverse diet, and baby birds and eggs are not exempt from their culinary preferences.


Snakes, although not active predators of baby birds, can still pose a significant threat to their survival. Tree-dwelling snakes, such as rat snakes, have been known to climb trees and raid nests for eggs. These cold-blooded predators use their stealth and agility to catch their prey and ensure their own survival.

Challenges for Baby Birds

Baby birds face numerous challenges and predators before they reach adulthood. Squirrels and other animals pose a significant threat to their survival, and their journey to maturity is fraught with peril.

Predation by Squirrels

As mentioned earlier, squirrels have been known to consume baby birds when given the opportunity. Their climbing abilities and agility enable them to access nests hidden within trees. Unattended nests become vulnerable targets, and the young chicks are at risk of falling prey to these cunning predators.

Predation by Other Animals

In addition to squirrels, baby birds face a myriad of other predators that pose a threat to their survival. Blue jays, crows, raccoons, opossums, and snakes, among others, can all target baby birds and eggs as a food source. The struggle for survival begins from the moment they hatch, and they must constantly navigate their environment and evade potential threats to ensure their own wellbeing.

In conclusion, squirrels are omnivores with a diverse diet that includes baby birds and eggs. However, their consumption of these food sources is opportunistic and primarily driven by hunger and the availability of other options. While squirrels may seem like unlikely predators of baby birds, their adaptability and opportunistic nature allow them to exploit various food sources to ensure their own survival. Baby birds face numerous challenges and predators before reaching adulthood, and squirrels are just one of many threats they must overcome.
