Can Feeding Bread to Squirrels Affect Their Natural Behavior?

Squirrels, those agile and often endearing creatures that dart through our gardens and parks, have a varied diet that primarily consists of nuts, seeds, and fruits. However, a common query among nature enthusiasts and homeowners alike is whether squirrels can safely consume bread, a staple in many human diets. 

This article delves into the intricacies of this question, balancing the natural dietary habits of squirrels with the nutritional profile of bread.

General Information About Squirrels and Bread

At a fundamental level, squirrels can consume bread. However, it’s not a natural part of their diet and offers little nutritional value. Bread, especially the processed and white varieties, lacks the essential nutrients squirrels need for a healthy lifestyle. 

While they may eat it when available, it doesn’t support their dietary requirements for proteins, fats, and vitamins found in their natural food sources.

Do Squirrels Like Bread?

Observationally, squirrels seem to exhibit a liking for bread. This preference can be attributed to the immediate energy boost provided by the carbohydrates in bread. However, liking a food does not necessarily make it suitable or healthy. 

The temporary satiation bread provides can lead to squirrels neglecting more nutritious food sources, which is not beneficial for their overall health.

Why Squirrels Cannot Digest Cellulose In Bread?

A significant component of bread, especially in its whole-grain form, is cellulose – a type of dietary fiber that squirrels cannot digest effectively. Their digestive systems are not equipped to break down cellulose into the necessary nutrients, making bread a poor dietary choice. 

This limitation is crucial in understanding why, despite its availability and palatability, bread should not be a regular part of a squirrel’s diet.

How to Incorporate Bread in the Diet of Squirrels?

If one chooses to feed bread to squirrels, it should be done sparingly and responsibly. Small amounts of plain, whole-grain bread can be offered occasionally as a treat.

However, it’s important to ensure that bread doesn’t replace the essential components of a squirrel’s natural diet, such as nuts and seeds.

Specific Types of Bread and Their Impact on Squirrels:

Bread comes in various forms, each differing in ingredients and nutritional content. Understanding these variations is crucial in assessing the impact they might have on squirrels.

Discussing Each Bread Type:

  • White Bread: Often made from refined flour, white bread lacks essential fibers and nutrients. For squirrels, it’s akin to empty calories, providing a quick energy boost without substantial nutritional benefits.
  • Whole Wheat Bread: Slightly better than white bread due to its fiber content, whole wheat bread still poses digestive challenges for squirrels. The cellulose in whole grains is difficult for squirrels to process.
  • High-Sugar Breads: Breads containing high amounts of sugar can be particularly harmful to squirrels. Excessive sugar can disrupt their energy levels and potentially lead to health issues.
  • Enriched Bread Flours and Added Vitamins: While enriched breads are designed to bolster human nutrition, the added vitamins and minerals may not align with a squirrel’s dietary needs. The unnatural supplementation can disrupt their nutritional balance.
  • Specialty Breads: Breads like garlic, banana, rye, French, and sourdough vary in ingredients and nutritional profiles. However, most contain elements that are not ideal for squirrels, such as spices, fruits, or dense grains that they cannot digest efficiently.

Considerations for Different Types of Squirrels:

Squirrels come in various species and ages, each with specific dietary requirements and restrictions. Understanding these differences is crucial when considering feeding them bread.

  • Gray Squirrels: Commonly found in urban areas, gray squirrels might be more accustomed to encountering bread. However, this doesn’t mean it’s beneficial for them. Their dietary needs are best met with natural foods.
  • Baby Squirrels: Young squirrels have sensitive digestive systems and are in a crucial stage of development. They require a diet rich in proteins and fats, which bread does not provide. Feeding bread to baby squirrels can be detrimental to their health.

Potential Harms of Feeding Bread to Squirrels:

While feeding squirrels might stem from a desire to help or interact with these animals, it’s vital to understand the potential risks involved in offering them bread.

  • Moldy Bread: Mold on bread can produce toxins harmful to squirrels. Even small amounts can cause health issues.
  • Preservatives and Added Sugars: Many commercial breads contain preservatives and sugars that are not suitable for squirrels. These additives can disrupt their natural diet and lead to health problems.
  • High Salt Content: Bread often contains salt, which in excess can be harmful to squirrels, potentially leading to dehydration or other health issues.

Guidelines for Feeding Bread to Squirrels:

Feeding wildlife, including squirrels, should be approached with caution and responsibility. When it comes to feeding bread to squirrels, certain guidelines should be followed to minimize potential harm.

Detailing Each Guideline:

  • Ensure Bread is Safe: If you choose to feed bread, ensure it’s free from mold and harmful additives. Fresh, plain bread is preferable.
  • Limit the Quantity: Bread should never constitute a significant part of a squirrel’s diet. Offer it only as an occasional treat, not a regular meal.
  • Soft Bread: Hard bread can be difficult for squirrels to eat whereas soft bread is easier for them to chew and digest.
  • Avoid Daily Feeding: Regular feeding with bread can lead to dependency and nutritional imbalances. It’s crucial to avoid making bread a consistent part of their diet.
  • Clean Feeding Area: Maintain cleanliness to prevent attracting pests or causing illnesses among the wildlife.
  • Types of Bread to Avoid: Steer clear of bread with high sugar, salt, or artificial additives. Specialty breads like garlic or banana bread should also be avoided due to their additional ingredients.

Alternative Foods for Squirrels:

Considering the limited nutritional value and potential risks of feeding bread to squirrels, exploring healthier alternative foods is beneficial.

Discussing Alternatives:

  • Nuts and Seeds: These are natural and nutritious options for squirrels, providing essential fats and proteins.
  • Fruits and Vegetables: Small portions of fruits and vegetables can offer squirrels vitamins and minerals.
  • Fungi and Mushrooms: In moderation, these can be a part of a squirrel’s natural diet, though it’s crucial to ensure they are safe and non-toxic.

Behavioral Implications of Feeding Bread to Squirrels: 

One crucial aspect to consider when feeding squirrels, particularly with bread, is the impact it may have on their natural behaviors, especially in terms of their foraging habits and dependency on human-provided food sources.

Squirrels’ Feeding Behavior and Human Interaction:

  • Squirrels are opportunistic feeders known for their ability to adapt to various food sources, including those provided by humans.
  • Regular feeding can lead to squirrels associating humans with easy food access, potentially altering their natural foraging behaviors.

The Impact of Bread on Squirrel Behavior:

  • Feeding bread to squirrels might encourage them to return to the feeding spot regularly, expecting to find food.
  • This reliance on human-provided food, especially one as nutritionally inadequate as bread, can disrupt their natural diet and foraging patterns.

Potential Risks of Habituation:

  • Habituation to human feeding can lead squirrels to become less wary of humans, which might not always be in their best interest, especially in urban environments where close proximity to humans can pose various risks.
  • Dependency on human food sources like bread can also lead to nutritional imbalances, as bread lacks the essential nutrients squirrels require for healthy growth and development.

While feeding bread might attract squirrels and cause them to return, it is essential to consider the long-term impacts on their health and natural behaviors.

Encouraging wild animals, like squirrels, to rely on human food sources can have unintended negative consequences. 

Therefore, if one chooses to feed squirrels, it should be done responsibly, ideally by providing foods that are closer to their natural diet.


In conclusion, while squirrels may consume bread without immediate harm, it does not provide them with the necessary nutrients and can pose health risks. It’s preferable to offer them foods that align more closely with their natural diet. When considering feeding squirrels, it’s crucial to prioritize their health and well-being over the temporary pleasure of human-animal interaction.
