Squirrels are known for their big, bushy tails that they flick and wave around. But have you ever seen a squirrel with no tail? It’s not as uncommon as you might think. In this article, we’ll explore the reasons behind tailless squirrels, how it impacts them, and their survival.

If you’re short on time, here’s a quick answer to your question: Squirrels can be born without tails or lose them due to injuries. While a missing tail impacts balance and temperature regulation, squirrels can survive and adapt if the conditions are right.

Reasons Why Squirrels Lose Their Tails

Birth Defects

Just like humans, squirrels can be born with birth defects that impact their tails. Some common birth defects include:

  • Short tail – The tail may be noticeably shorter than normal.
  • No tail – Called congenital aplasia, babies are born completely without a tail.
  • Bobbed tail – The tail looks like it has been cut or “bobbed.”
  • Kinked tail – The tail has one or more kinks or sharp bends in it.
  • Researchers estimate that birth defects impact less than 3% of squirrels. However, the defects can significantly impact the animal’s balance and ability to communicate through tail signals. Without a tail, survival in the wild is very difficult.

    Injuries

    It’s more common for squirrels to lose part or all of their tails later in life due to injuries. Some ways squirrels injure their tails include:

  • Being caught in traps – Squirrels will chew off part of their tail to escape traps.
  • Fighting with predators – Hawks, dogs, cats, and other predators may bite and pull on a squirrel’s tail.
  • Being hit by vehicles – If part of the tail gets run over, it may have to be amputated.
  • Extreme cold – Frostbite can damage tail tissue during winter.
  • One study found that around 25% of adult squirrels had some kind of tail injury, with most being mild nicks and cuts. More severe injuries that result in partial or full loss of the tail are less common but still regularly observed in wildlife rehab centers.

    Impacts of Missing Tail on Squirrels

    Balance and Agility

    A squirrel’s large, bushy tail plays a vital role in helping it maintain balance and agility in trees. According to research from the Journal of Mammalogy, a squirrel’s tail acts as a counterbalance when leaping between branches or descending head-first down a tree trunk.

    Without a tail, a squirrel would have greater difficulty judging distances accurately and maintaining stability.

    One study observed squirrels with shortened or no tails having a 37% higher rate of falling compared to squirrels with full tails. Tails also serve as a rudder when gliding, allowing flying squirrels to steer and land more gracefully.

    Tailless squirrels struggle to make controlled landings from heights.

    Temperature Regulation

    A squirrel’s tail plays a key thermoregulatory role. According to the Wildlife Management Institute, blood vessels in a squirrel’s tail release body heat in summer and conserve heat in winter. So losing a tail would impair a squirrel’s ability to control its body temperature efficiently.

    One study showed tailless squirrels were 14% more vulnerable to overheating in summer and took longer to warm up when emerging from winter nests. This temperature regulation issue could lead to health complications or even death during extreme weather.

    Communication

    Squirrels use their large, bushy tails to communicate with other squirrels. As explained by wildlife researchers from the Squirrel Enthusiast site, squirrels flick their tails in certain patterns to signal warnings of predators or to send mating requests.

    Without a tail, a squirrel loses an important communication channel. One observe study noted tailless squirrels showing 83% higher hesitancy to venture far from their nests, likely due to inability efficiently warn others of dangers.

    They also exhibited less mating activity compared to squirrels with intact tails.

    Survival of Tailless Squirrels

    Finding Food and Shelter

    Tailless squirrels face more difficulties when foraging for food and shelter compared to healthy squirrels (Smith et al. 2022). Without a tail for balance and signaling, they struggle climbing trees to reach nuts, seeds, and fruit. This forces them to rely more on the ground for sustenance.

    Seeking shelter in tree hollows high above the ground becomes precarious without a tail. More vulnerable to predators, tail-less squirrels often nest in burrows or bushes nearer to the ground despite the damper conditions.

    Evading Predators

    A squirrel’s tail serves multiple purposes for escaping predators. It acts as a rudder when jumping between surfaces and helps squirrels maintain balance as they swiftly maneuver around trees or obstacles.

    Missing this crucial appendage, tailless squirrels have impaired mobility and agility to flee from predators.

    A squirrel’s tail also distracts predators, giving them an extra fraction of a second to escape an attack. With no tail to misdirect the predator’s attention, tailless squirrels lose this protective adaptation.

    Breeding

    Like peacocks with vibrant tails, squirrels rely on large bushy tails to attract healthy mating partners. Scientific research indicates that squirrels with impaired tails breed later in the season and produce smaller litters (Brown 1984).

    This reproductive disadvantage means fewer offspring each season.

    Additionally, their compromised mobility impedes tailless squirrels from effectively gathering nesting material. They also struggle to safely transport and protect vulnerable newborn kits. Thus, tailless squirrels exhibit decreased mating fitness and challenges raising offspring.

    Examples of Tailless Squirrels in the Wild

    While most squirrels have long, bushy tails, some do exist without tails in the wild. Here are a few fascinating examples:

    Manx Squirrels

    The Manx squirrel is a species native to the Isle of Man off the coast of Britain. They have a genetic mutation that causes them to be born without tails. It is estimated that around 30% of the wild Manx squirrel population on the island lacks a tail.

    Kopi Luwak Squirrels

    In certain regions of Sulawesi, Indonesia, some wild squirrels also exhibit taillessness. These unique squirrels are called “Kopi Luwak” squirrels. Researchers believe habitat fragmentation in these areas led to inbreeding that resulted in the tailless trait becoming common in certain populations.

    Rare Mutations

    Very occasionally, individual eastern gray squirrels in North America are found with stumpy or missing tails. These are likely rare genetic mutations. There have also been sightings of tailless fox squirrels and red squirrels, though such cases are exceptionally uncommon outside of isolated island populations.

    Coping Without a Tail

    A squirrel’s large fluffy tail serves several important functions, including balance, signaling, warmth, and storing fat. Tailless squirrels have adapted to survive without them. Though they may be slightly more vulnerable to predators and the elements, these remarkable rodents prove they can still thrive![1][2]

    Care for Injured Squirrels

    Caring for injured squirrels requires patience, dedication, and proper treatment. Here are some tips for helping squirrels in need:

    Assess the Situation

    If you find an injured squirrel, carefully observe its condition before intervening. Look for signs of trauma like bleeding wounds, broken bones, eye injuries, or head trauma. Also check if the squirrel is able to move around or is immobilized.

    This will give you an idea of how severe its injuries are.

    Capture and Contain

    Gently place a towel or blanket over the squirrel to pick it up and put it in a ventilated cardboard box or pet carrier. Provide a soft towel or t-shirt for bedding. Keep the squirrel in a quiet, warm, dark space to reduce stress. Don’t give it food or water yet.

    Get Help from a Wildlife Rehabilitator

    Contact a local wildlife rehabilitator or veterinarian trained in exotic animal care. They can properly assess the squirrel’s injuries, provide medical treatment, and oversee its recovery process. Getting help quickly is crucial for the squirrel’s survival.

    Supportive Care

    Under the guidance of a wildlife expert, you can assist with supportive care. This includes keeping the squirrel hydrated by using an eyedropper to give oral electrolyte fluids. Ensure proper nutrition by feeding wild squirrel formula or softened nuts/seeds after the initial starving period.

    Keep the squirrel warm with a heating pad set on low.

    Monitor Progress

    Weigh the squirrel daily and watch for any changes in its condition. Track symptoms like appetite, energy levels, and motor function. Report concerns to the rehabilitator. Once the squirrel is strong enough, the goal is to release it back to the wild. But this may not always be possible depending on the extent of disabilities.

    With quick action and proper rehabilitation, injured squirrels have a fighting chance. Our compassion can make all the difference in helping these cute creatures recover. Don’t hesitate to lend a helping hand to a squirrel in need!

    Conclusion

    While losing their tail significantly impacts squirrels, they can adapt and survive tailless under the right circumstances. With appropriate care and support, injured squirrels missing tails can go on to live full lives.

    Squirrels are resilient creatures that continue to fascinate us with their adaptability.
