If you’re a fan of squirrels, Alaska is the perfect place for you. With its vast wilderness and varied landscape, Alaska is home to several types of squirrels that you won’t find anywhere else.
From the tiny red squirrel to the elusive northern flying squirrel, each species has its unique features that make them fascinating to observe.
Key Takeaways
- Red squirrels, also known as chickarees, are common in Alaska and have a unique diet of seeds, nuts, and fungi.
- Arctic ground squirrels are well adapted to the harsh Arctic climate, hibernate for up to 8 months, and dig their own burrows.
- Flying squirrels use a membrane of skin called a patagium to glide through the air, prefer forested areas with a variety of food sources, and are nocturnal opportunistic feeders.
- Marmots are ground squirrels found in the alpine tundra of Alaska, known for their social behavior and complex burrow systems, and play an important role in the alpine ecosystem.
1. Red Squirrel (Chickaree)
You’ll often hear the Chickaree’s high-pitched chatter as it scurries through the trees, its reddish-brown fur blending in with the autumn leaves.
The Red Squirrel, also known as the Chickaree, is one of the most common types of squirrels in Alaska. It’s smaller than its gray squirrel cousin and has a more pointed face, with tufted ears and a bushy tail.
Red squirrels in Alaska have a unique diet, consisting of seeds, nuts, and fungi. They’re known for their impressive ability to store food for the winter, and their sharp teeth help them crack open tough nuts and seeds.
Unlike gray squirrels, which prefer to live in urban areas, red squirrels in Alaska are found in forests and other wooded areas. They build their nests, called dreys, out of leaves and twigs, and use them to raise their young and stay warm in the winter.

2. Arctic Ground Squirrel
The Arctic Ground Squirrel is a fascinating creature, known for its ability to survive in harsh environments through hibernation and other adaptations. The Arctic Ground Squirrel is found throughout Alaska, from the coastal plains to the foothills of the Brooks Range.
These squirrels are active mainly during the summer months, when they have access to food and warmth. During the winter, they hibernate in their burrows, which they dig themselves. Arctic Ground Squirrels are known for their unique hibernation habits.
They hibernate for up to 8 months of the year, and their body temperatures drop to near freezing. They’re able to survive these harsh conditions because they have special adaptations that allow them to slow down their metabolism and conserve energy. These adaptations include a decreased heart rate and a reduction in the size of their organs.
Despite their amazing ability to survive in the harshest of environments, Arctic Ground Squirrels face threats from climate change and habitat loss, making it important to understand and protect these amazing creatures.
3. Flying Squirrel
Flying squirrels are fascinating creatures that have the amazing ability to glide through the air, making them a unique and interesting addition to the world of squirrels. They are a nocturnal species and use their large eyes to navigate in the dark.
They glide from tree to tree using a membrane of skin called a patagium, which stretches from their wrists to their ankles. This allows them to glide for up to 150 feet, making them the champions of the squirrel world.
Flying squirrels prefer to live in forested areas where they can easily find a variety of food sources such as nuts, seeds, and insects. They are found throughout Alaska but are most commonly found in the southeast regions of the state.
They are social animals and will often share nests with other squirrels, such as their young or their mate. Despite their name, flying squirrels do not actually fly, but their impressive gliding abilities make them a true wonder of the animal kingdom.
4. Northern Flying Squirrel
If you’re lucky enough to spot one, you’ll be amazed by the Northern Flying Squirrel’s ability to glide through the air using a patagium. This furry mammal is a nocturnal creature that can be found in the boreal forests of Alaska.
Here are some interesting facts about the Northern Flying Squirrel:
- They are omnivorous and feed on a variety of food including lichens, fungi, insects, and nuts.
- During the winter months, they enter a state of hibernation to conserve energy and survive the harsh cold weather.
- They are social creatures and live in groups of up to 20 individuals. They communicate with each other using a range of vocalizations and scent marking.
In terms of hibernation habits, Northern Flying Squirrels have a unique way of surviving the cold winter months. They enter a state of torpor, where their body temperature drops significantly to conserve energy.
During this time, they rely on their stored body fat to survive.
As for their diet preferences, they are opportunistic feeders and will eat whatever food is available to them. This includes a variety of plant material, insects, and even other small animals.
Overall, the Northern Flying Squirrel is an interesting species that has adapted to survive in the harsh environments of Alaska.
5. Marmot
You’ll be surprised by how much personality a Marmot has when you observe them in their natural habitat. Found in the alpine tundra of Alaska, these ground squirrels are known for their social behavior.
They live in complex burrow systems that can house up to 20 individuals. Marmots are active during the day, spending most of their time foraging for food such as grasses, sedges, and wildflowers.
They also hibernate for up to 8 months during the winter, relying on the fat stores they accumulate during the summer months. Marmots are known to be very vocal, communicating with each other through a series of chirps, whistles, and barks.
They are a fascinating species to observe in their natural habitat and play an important role in the alpine ecosystem.
Frequently Asked Questions
What is the lifespan of a squirrel in Alaska?
Squirrels in Alaska have a lifespan of three to six years. Their behavior and habitat preferences vary, but they generally prefer coniferous forests and feed on nuts, seeds, and insects.
How do squirrels adapt to the extreme cold temperatures in Alaska?
To survive extreme cold temperatures in Alaska, squirrels hibernate during the winter months and rely on winter food storage. During hibernation, their body temperatures drop and their metabolism slows down, allowing them to conserve energy until warmer temperatures return.
What is the mating season for squirrels in Alaska?
Squirrel behavior in Alaska is influenced by the reproductive habits of the species. The mating season varies, with some species mating in early spring and others in late summer. Factors such as temperature and food availability also play a role in their reproductive cycles.
How do squirrels in Alaska differ from those in other parts of the world?
Squirrels in Alaska exhibit unique behavioral patterns and habitat preferences compared to other regions. They have adapted to the harsh winters by hoarding food and hibernating. They also prefer coniferous forests and have a diverse diet.
What is the impact of human development on squirrel populations in Alaska?
Human interference through development has led to habitat loss and fragmentation in Alaska, negatively impacting squirrel populations. Conservation efforts aim to protect remaining habitats and promote connectivity to ensure the survival of these important ecosystem contributors.
