Do Squirrels Eat Other Squirrels? Shocking Discovery Revealed!

As a nature lover with several years of experience observing and interacting with squirrels around the world, I was shocked to discover that some squirrels do in fact eat other squirrels! In this blog post, I will share my findings and discuss why it is important to consider this behavior when studying these fascinating creatures.

Squirrels are omnivores that primarily eats seeds, nuts, fungi, and other plant foods. They have been known to occasionally feed on small insects and even eggs or chicks of other birds. However, it is quite rare for squirrels to eat their own species (i.e. cannibalism).

Do Squirrels Eat Other Squirrels?

It may come as a shock to some but recent studies have revealed that the ingestion of conspecifics by squirrelsmeaning other members within its own species – may not be uncommon. Research indicates that in some cases cannibalism can occur among squirrel populations due largely to environmental conditions or predator behavior.

In addition to environmental elements such as temperature fluctuations or shortages in food availability, predation plays a major role in intraspecific predation among rodents. Studies have also indicated that social hierarchy within these species can also influence the consumption of conspecific members.

The Shocking Discovery Revealed!

It has long been believed that squirrels are largely vegetarian creatures, but recent research suggests that – in certain circumstances – the little rodents may resort to eating one another. This phenomenon, known as “intraspecific predation”, or cannibalism, has gained attention in academic circles due to its implications for human-biodiversity management.

Just what is intraspecific predation? It is defined as the act of one organism ingesting another member of its own species. In other words, a squirrel may choose to consume another squirrel when food supplies are limited or energy demands are exceptionally high.

“Cannibalism” in Squirrels – What Does Science Say?

Recent studies have shown that intraspecific predation does occur among some squirrel species, though it is not an everyday occurrence. For example, red and gray foxes have both been observed killing and consuming gray squirrels. Additionally, captive grey squirrels were recorded killing each other during challenging environmental conditions (such as cold weather).

In the wild, these types of deaths usually involve younger individuals who lack experience and which would otherwise become easy prey for predators such as hawks and eagles. Therefore, their cannibalistic behaviors can be seen not only as a last resort but also a means to protect themselves from outside threats.

Factors That Influence Cannibalism in Squirrels

Predation and Rodent Behavior

Environmental Conditions and Food Availability

Apart from natural predators, environmental factors also play an important role in whether or not intraspecific predation occurs in any given population. Studies suggest that especially challenging environmental conditions – such as extreme temperatures or drought – might lead adult male squirrels to attack juveniles if food resources are scarce.

It should be noted however that there needs to be more research conducted on this subject before definitive conclusions can be drawn regarding which specific conditions (if any) promote intraspecific predation within rodent populations.

The Role of Social Hierarchy in Intraspecific Predation

Not surprisingly perhaps; there’s evidence suggesting social hierarchies also influence whether siblings will engage in predatory behavior against one another or not. Generally speaking; weaker members of mouse groups tend to end up being eaten by dominant adults while littermates will often display cannibalistic behavior towards each other with age asymmetry playing an important part here too.

All things considered; it seems likely that although uncommon; there definitely are occasions where you might get two members of the same species targeting each other for sustenance purposes rather than competition like we usually believe about animal behavior.

The Effects Of Human Interference On Natural Behavior

Humans play an integral role in determining how wildlife behaves; whether it’s habitat destruction resulting from deforestation or hunting practices influencing prey availability — our actions shape how predators perceive their surroundings.

Intraspecific predation scales up when humans disrupt normal patterns by providing unbalanced opportunities ( e. g., limited amounts of edible vegetation ). Food shortages then contribute to increased competition levels amongst members within a given population.

Furthermore, international trade networks facilitate the introductions of invasive who may compete with resident natives need specific resources like food or nesting spots – leading inevitably towards possible hostile interactions.. Awareness needs to be kept concerning how human activities put pressure on nature so we maximize our conservation efforts going forward!

As human interference continues to make its mark upon the world’s habitats, the impact of our activities is seen in many ways. For example, as more land is developed for agricultural or residential use by humans, it often reduces the amount of suitable food sources for wild animals like squirrels. This artificial reduction can foster a higher rate of intraspecific competition within affected populations.

In addition to limiting food supplies and damaging natural ecosystems, human development can also contribute to an increase in predation. As humans introduce new predators into an area through their pet ownership or other activities, these new predators may seek out local wildlife for prey – including squirrels. This new source of predation puts added pressure on squirrel populations and may inadvertently lead to a rise in intraspecific cannibalism.

How Intraspecific Predation Occurs Due to Human Impact

Cannibalism is a practice not uncommon among rodents such as squirrels – though it typically occurs only under certain conditions. Researchers suggest that there are numerous external factors which could promote intraspecific predation among rodent populations living near human settlements.

  • Food Availability: When food resources become scarce due to human activity, such as cultivation and deforestation, rodents may turn on each other as a way of surviving on limited resources.
  • Environmental Conditions: Predators introduced into an environment due to humans will sometimes hunt out rodents for food – leading some individuals towards preying on members of their own species when predator numbers are large enough.
  • Social Hierarchy: In environments with high concentrations of rodents such as those near urban areas or agricultural sites, social hierarchies may form amongst population members which could result in dominant individuals being more likely than others to engage in cannibalistic behavior.

Finally – while scientists cannot definitively conclude that the ingestion of conspecifics by squirrels is caused primarily by human activity – they do suggest that it is likely influenced by changes induced by us – thus making our presence felt even within wild animal communities living close by.


Despite the shocking discovery that do squirrels eat other squirrels, it must be noted that this behavior is rare. Squirrels are mostly herbivorous, and only in certain circumstances will they consume meat as a last resort. The most important takeaway from this discovery is to remember that while squirrels may occasionally catch and eat one another, it should not be assumed that all squirrels practice cannibalism.

All in all, we can confidently say – no, do squirrels generally do not eat other squirrels. This behavior appears to have evolved as a way for some species to survive extreme environmental conditions. Thus, thanks to research and scientific evidence, we can now definitively answer the question: do squirrels eat other squirrels? With a “Yes”, but rarely and only in certain conditions.
