    The Siberian flying squirrel is a small and fascinating creature living in the vast forests of Siberia. These squirrels are special not only because they can glide from tree to tree, but also because of what they eat.

    Knowing about their diet is important for anyone interested in keeping them safe in the wild or as a pet. Their food choices are closely linked to where they live and how they behave. This link is a key part of nature’s balance.

    Let’s take a closer look at these interesting animals and learn why what they eat is so important for their health and the environment they live in.

    The Siberian Flying Squirrel

    The Siberian flying squirrel, a small and elusive mammal, captures the imagination with its unique adaptations and behaviors. Native to the boreal forests of Siberia, this species has evolved to thrive in a specific and challenging environment. In this section, we’ll delve into the distinct characteristics and habitat of these remarkable creatures.


    The Siberian flying squirrel is known for its soft, grey fur and large, dark eyes. It’s relatively small, usually measuring between 15 to 20 centimeters in body length. One of its most distinctive features is the furry membrane stretching between its front and back legs.

    This membrane, called a patagium, allows it to glide gracefully between trees, traveling distances up to 50 meters in a single leap.


    These squirrels reside in dense, old-growth forests, where tall trees provide the canopy cover they need for gliding. They prefer areas with a mix of coniferous and deciduous trees, which offer both shelter and a variety of food sources. These forests also provide essential nesting sites, typically in holes in trees or in nest boxes if available.

    Unique Characteristics

    Apart from their gliding ability, Siberian flying squirrels are notable for their nocturnal lifestyle. Active mostly at night, they are adept at moving silently through the forest, avoiding predators. Their large eyes are adapted for night vision, helping them see in low light conditions. Additionally, these squirrels play a crucial role in their ecosystem, aiding in seed dispersal and serving as prey for larger animals.

    The Diet of the Siberian Flying Squirrel

    Understanding the diet of the Siberian flying squirrel offers insights into their survival and the ecological niche they occupy. Let’s explore what these intriguing creatures feast on and how their dietary habits compare with other flying squirrel species.

    What Do Siberian Flying Squirrels Eat?

    The diet of the Siberian flying squirrel is diverse, reflecting their adaptability to the seasonal availability of food. Primarily, they feed on a variety of plant-based items such as leaves, buds, flowers, seeds, and occasionally fruits. During the spring and summer, their diet is richer in fresh vegetation and insects, providing them with necessary proteins and other nutrients.

    In the colder months, their diet shifts to include more seeds and nuts, which are energy-dense and crucial for their survival during the harsh Siberian winters. They are also known to consume tree sap, a source of sugars and minerals. This varied diet is essential for their health, providing a balance of carbohydrates, proteins, and fats.

    Comparison with Other Flying Squirrels

    While there are similarities, the diet of the Siberian flying squirrel also differs from other flying squirrel species. For instance, the North American flying squirrel tends to have a diet more heavily reliant on fungi, especially during the summer and fall. They also consume more animal matter, such as insects and bird eggs, compared to their Siberian counterparts.

    The differences in diet among flying squirrel species are largely influenced by their respective habitats and available food sources. While Siberian flying squirrels adapt to the colder, more varied climate of Siberia, other species have evolved dietary habits that suit their specific environmental conditions.

    This diversity in diet among flying squirrel species showcases the adaptability and ecological versatility of these fascinating mammals.

    Feeding Habits: Foragers and Hoarders

    The Siberian flying squirrel is not just an agile glider but also a skilled forager and hoarder. Their methods of gathering and storing food are as fascinating as their aerial acrobatics. Let’s take a closer look at how these fluffy acrobats manage their pantry in the wild.

    Gathering Food

    Siberian flying squirrels are opportunistic feeders, meaning they eat whatever the forest offers. During their nocturnal outings, they leap from branch to branch, searching for a variety of foods. These squirrels have a knack for finding seeds, nuts, fruits, and leaves, making each foraging trip a sort of forest buffet adventure.

    Their excellent memory helps them remember where the best feeding spots are. They use their sharp senses to sniff out food and can even detect hidden or buried food under the snow. It’s a bit like a nightly treasure hunt, where the prize is a tasty morsel!

    Storing for the Future

    But these squirrels are not just about eating for the day; they’re thinking ahead. They store food to get through the tough Siberian winters. They tuck away nuts and seeds in tree crevices, holes, or even under layers of snow – their own natural freezer.

    This hoarding behavior is crucial for their survival. When food becomes scarce in winter, these stored reserves become their lifeline. It’s like having a pantry stocked with snacks for a snowy day. By spring, their foresight pays off, and they have enough energy to start the cycle again.

    Health and Nutrition

    For Siberian flying squirrels, a balanced diet is not just a choice; it’s a necessity for good health. Like us, these little creatures need a mix of different foods to stay fit and spry. Let’s dive into the essentials of their diet and what foods they should steer clear of.

    The Importance of Variety

    Variety is the spice of life, and this holds true for Siberian flying squirrels too.

    A diet that includes a range of plant-based foods provides them with all the necessary nutrients. Leaves, buds, flowers, seeds, and fruits offer a cocktail of vitamins, minerals, and energy. This diversity in their diet helps maintain their energy levels, supports a healthy immune system, and contributes to overall well-being.

    In the wild, their diet changes with the seasons, which naturally ensures they get a wide range of nutrients throughout the year. This natural diet rhythm helps them stay in tune with their environment and maintain their health.

    Foods to Avoid

    While Siberian flying squirrels are not overly picky eaters, there are certain foods they should avoid. Foods high in sugar or fat, which are not typically found in their natural diet, can be harmful. Also, processed human foods, salty snacks, and anything with artificial additives should be off the menu. These items can disrupt their digestive system and lead to health issues.

    In captivity, it’s crucial to mimic their natural diet as closely as possible and avoid giving them anything that they wouldn’t find in the wild. By doing so, we can help ensure these charming creatures stay healthy and happy.

    Caring for a Siberian Flying Squirrel

    Bringing a Siberian flying squirrel into your home is a unique and rewarding experience. However, it’s crucial to understand their dietary needs to keep them healthy and happy in captivity. Here are some tips on feeding these adorable pets and addressing common dietary concerns.

    Feeding in Captivity

    In captivity, the goal is to replicate the Siberian flying squirrel’s natural diet as closely as possible. Offer them a variety of fruits, vegetables, nuts, and seeds to mimic the diversity they would find in the wild. You can include apples, pears, berries, carrots, and leafy greens. Nuts like almonds and walnuts are great too, but in moderation, as they are high in fats.

    Ensure that fresh water is always available. Additionally, you can supplement their diet with specialized small rodent food available at pet stores to make sure they’re getting all the necessary nutrients.

    It’s important to serve food in a way that encourages their natural foraging behavior. Scatter food around their enclosure to make mealtime a little adventure, mimicking the way they’d search for food in the wild.

    Common Dietary Concerns

    One of the main concerns for pet Siberian flying squirrels is obesity. A diet too high in fat can lead to weight gain, so it’s important to balance their intake of nuts and seeds with plenty of fruits and vegetables.

    Also, be cautious with sugary fruits. While they enjoy them, too much sugar can lead to digestive issues and even diabetes. Variety is key, but it should be balanced.

    Lastly, watch out for signs of nutritional deficiencies. If your squirrel’s coat isn’t as shiny as it should be or if they seem lethargic, it might be a sign that their diet needs adjustment. In such cases, consulting with a veterinarian who has experience with exotic pets is always a wise decision.

    Sustaining Your Siberian Flying Squirrel’s Health

    Ensuring your Siberian flying squirrel thrives involves mimicking their wild diet: a blend of leaves, seeds, and occasional fruits. Steer clear of sugary treats and overly fatty foods to avoid health issues.
