With its tropical climate and lush vegetation, Hawaii may seem like the perfect habitat for squirrels. However, if you’ve visited the islands, you’ve likely noticed a distinct lack of these bushy-tailed rodents scampering about.
So do squirrels actually live in Hawaii? The short answer is no, there are no native squirrel species found in the Hawaiian islands today. But that doesn’t mean squirrels have never inhabited Hawaii.
Read on to learn everything you need to know about the history of squirrels in Hawaii and why they are absent from the islands today.
Here’s a quick overview of the key points we’ll cover in this comprehensive guide to squirrels in Hawaii:
Historical Presence of Squirrels in Hawaii
When we think of squirrels, we often picture them scurrying around in parks or forests on the mainland. But what about squirrels in Hawaii? Are there any squirrels living in this tropical paradise? Let’s explore the historical presence of squirrels in Hawaii to find out.
Fossil Evidence of Ancient Squirrels
Although squirrels are not native to Hawaii, there is evidence to suggest that they once inhabited the islands. Fossil remains of ancient squirrels have been discovered, indicating that these furry creatures were present in Hawaii thousands of years ago.
These fossils provide valuable insights into the natural history of the islands and the diverse range of species that once called Hawaii home.
Documented Sightings in the 1800s
During the 1800s, there were several documented sightings of squirrels in Hawaii. These sightings were mainly reported by European explorers and naturalists who visited the islands during that time. These accounts describe encounters with squirrels in various parts of Hawaii, including the main islands of Oahu and Maui.
It is important to note that these sightings were isolated and did not indicate the establishment of a sustainable squirrel population in Hawaii. The limited presence of squirrels during this period suggests that they may have been introduced to the islands unintentionally or were brought over as pets.
Intentional Introductions That Failed
In an attempt to establish a squirrel population in Hawaii, intentional introductions were made in the past. However, these efforts were unsuccessful.
The climate and ecological conditions in Hawaii were not suitable for squirrels to thrive and reproduce. The lack of natural predators and competition with other native species may have also contributed to their inability to establish a sustainable population.
As a result, squirrels remain absent from the Hawaiian islands today. Although there have been occasional sightings reported by locals and tourists, these are likely to be squirrels that have been accidentally transported to Hawaii or released as pets.
So, if you’re planning a trip to Hawaii and hoping to spot some squirrels, you might be out of luck. But don’t worry, the islands have plenty of other unique and fascinating wildlife to offer!
Reasons Why Squirrels Don’t Live in Hawaii Today
Isolation of the Islands
The isolation of the Hawaiian Islands is one of the main reasons why squirrels are not found in Hawaii today. The archipelago is located in the middle of the Pacific Ocean, far away from any mainland.
This isolation makes it difficult for squirrels to naturally migrate to the islands. While there have been introductions of various animal species throughout history, squirrels have not been able to establish a population in Hawaii.

Lack of Natural Predators
In the absence of natural predators, the squirrel population can increase rapidly, leading to potential ecological imbalances. One of the factors that have prevented squirrels from establishing themselves in Hawaii is the lack of natural predators.
The islands’ ecosystem evolved without the presence of squirrels, and the native bird and plant species have not developed defenses against them.
Unsuitable Habitat and Diet
The Hawaiian Islands have a unique ecosystem that is quite different from the mainland. The islands are characterized by lush rainforests, volcanic landscapes, and coastal habitats.
Unfortunately, these habitats do not provide the necessary conditions for squirrels to thrive. Squirrels require specific types of trees for nesting and food sources, which are not abundant in Hawaii.
Strict Quarantine Laws
Hawaii has strict quarantine laws in place to protect its delicate ecosystem from invasive species. This includes regulations on bringing animals into the state.
These laws aim to prevent the introduction of pests, diseases, and invasive species that could harm the native flora and fauna. Due to these regulations, it is challenging for squirrels or any other non-native animals to be brought into Hawaii legally.
So, if you ever find yourself in Hawaii and spot a squirrel, chances are it’s not a native species but rather an introduced pet or escaped animal. While squirrels may be a common sight in many parts of the world, they have yet to make their way to the beautiful islands of Hawaii.
The Closest Squirrel Relatives in Hawaii
When we think of squirrels, we often picture them scurrying through trees and parks on the mainland. However, did you know that Hawaii also has its own unique creatures that are closely related to squirrels?
While there are no true squirrels native to the Hawaiian islands, there are two fascinating species that share some similarities with our furry friends.
Oahu Tree Shrews
Oahu tree shrews, scientifically known as Nesophontes, are small mammals that are endemic to the Hawaiian island of Oahu. Despite their name, they are not actually shrews but are more closely related to squirrels. These tree shrews have a slender body with a long tail, similar to squirrels, and they are skilled climbers, spending most of their time in the trees.
These tree shrews have a varied diet, feeding on a wide range of fruits, insects, and nectar. They play an important role in pollination as they visit flowers to feed on nectar, inadvertently transferring pollen in the process.
While they may not resemble squirrels in appearance, their ecological role and behavior make them an interesting part of Hawaii’s diverse wildlife.
So, while squirrels may not be native to Hawaii, the Oahu tree shrews are fascinating examples of the close relatives that can be found on the islands. Their unique adaptations and behaviors make them an important part of Hawaii’s natural heritage.
If you ever find yourself in Hawaii, keep an eye out for these remarkable creatures and appreciate the diversity of life that exists beyond the mainland.
Could Squirrels Be Introduced to Hawaii in the Future?
While squirrels are not native to Hawaii, there have been proposals to introduce them to the islands. Proponents argue that squirrels could have a positive impact on the ecosystem and enhance the biodiversity of Hawaii.
However, introducing squirrels to a new environment is not without its challenges and potential risks.
Proposals to Introduce Squirrels
Some individuals and organizations have suggested introducing squirrels to Hawaii to fill ecological niches that are currently vacant. They believe that squirrels could play a role in seed dispersal and tree regeneration, similar to their role in other ecosystems.
Additionally, squirrels could potentially serve as a food source for native predators, helping to balance the food web. However, it is important to carefully consider the potential impacts before moving forward with any introduction plans.
Potential Impacts on the Ecosystem
Introducing squirrels to Hawaii could have both positive and negative effects on the ecosystem. On one hand, squirrels could help in the dispersal of seeds, leading to the growth of new vegetation and potentially benefiting other native species.
On the other hand, squirrels are known to eat a wide variety of foods, including fruits, nuts, and bird eggs. This could potentially have negative consequences for native plant species and bird populations.
It is also important to consider the potential competition squirrels may pose to native species. Hawaii is home to a unique array of plants and animals that have evolved in isolation, and the introduction of a non-native species could disrupt these delicate ecosystems.
Another factor to consider is the potential biosecurity risks associated with introducing squirrels to Hawaii. Squirrels can carry diseases and parasites that could pose a threat to native wildlife. Additionally, once introduced, squirrels may be difficult to control and could become invasive, outcompeting native species for resources and potentially causing harm to the environment.
Before any introduction plans are considered, a thorough risk assessment must be conducted to evaluate the potential impacts on the ecosystem and the effectiveness of any mitigation measures.

Where to See Squirrels in Hawaii Today
If you’re visiting Hawaii and have a soft spot for squirrels, you might be wondering if you can spot these furry creatures on the islands. While squirrels are not native to Hawaii, there are a few places where you can still catch a glimpse of them.
Squirrels in Zoos and Wildlife Parks
One of the best places to see squirrels in Hawaii is at zoos and wildlife parks. These facilities often have dedicated areas where visitors can observe and learn about different species of animals, including squirrels.
One such place is the Honolulu Zoo, located in the heart of Honolulu. The zoo is home to a variety of animal species, including several types of squirrels. Visitors can watch these agile creatures as they scamper around their enclosures, displaying their acrobatic skills.
Another popular destination is the Maui Ocean Center, an aquarium that showcases the marine life of Hawaii. While you might not expect to see squirrels at an aquarium, the center has a small outdoor area where you can find a few squirrels frolicking among the trees. It’s a unique opportunity to witness squirrels in a more natural environment.
Pets and Escaped Squirrels on the Islands
Although squirrels are not native to Hawaii, there have been instances where they have been brought to the islands as pets. While it is not recommended to keep squirrels as pets due to their specific needs and potential impact on the environment, some individuals have chosen to do so. As a result, there have been cases where squirrels have escaped or been released into the wild.
If you happen to come across a squirrel while exploring Hawaii, it is essential to remember that they are not part of the native fauna. It is best to observe them from a distance and not attempt to interact with or feed them. It’s important to respect the natural balance of the ecosystem and avoid introducing non-native species into the environment.
