Average Life Span of Different Squirrel Species
Squirrels are fascinating creatures that thrive in various habitats throughout Toronto, Ontario, from lush forests to urban parks. Their lifespan depends on several factors, including species, habitat, and exposure to predators. Understanding the squirrel’s lifespan can help homeowners and wildlife enthusiasts appreciate these small mammals and take preventive measures against potential squirrel infestations.
The average lifespan of a squirrel varies depending on its species and environment.
- Eastern Gray Squirrel (Sciurus carolinensis): In the wild, these tree squirrels live an average of 6 years, but some can reach 12 years.
- Fox Squirrels (Sciurus niger): Fox squirrels live between 8 and 18 years in ideal conditions.
- Red Squirrels: These small tree-dwelling squirrels have a life expectancy of about 5 years.
- Flying Squirrels: These nocturnal species live around 5 to 6 years in the wild.
- Ground Squirrels: Their average lifespan is about 3 to 5 years due to higher exposure to predators.
Squirrel Lifespan in Captivity
Squirrels in captivity live longer than their wild counterparts due to no predators, consistent food and medical care.
- Eastern Gray Squirrels: Up to 20 years, some into their late teens with optimal care.
- Fox Squirrels: 18-20 years with proper nutrition and veterinary care.
- Red Squirrels: They can live beyond their 5 year lifespan, 8-10 years in captivity.
- Flying Squirrels: Protected from natural dangers, they can live up to 10 years or more in captivity.
- Ground Squirrels: Shorter lifespan in the wild, 7-10 years with proper care in captivity.
A controlled environment greatly extends a squirrel’s lifespan, diet, shelter and medical care have the most impact on longevity.
Factors That Affect a Squirrel’s Lifespan
Squirrels live longer in environments with fewer threats and ample food sources. Several factors determine how long squirrels live:
1. Habitat and Environment
- Wild squirrels face predators and harsh weather conditions, reducing their lifespan.
- Urban environments provide food accessibility, but squirrels in city parks and urban areas encounter dangers like electrical wires and traffic.
- Squirrels are vital to the eco system, they can bury nuts or seeds in forests or parks, and if they fail to return for them, they’ve actually planted new trees without knowing it.
2. Predators and Threats
- Natural predators include hawks, foxes, and snakes, squirrels must keep a constant vigilance. Baby squirrels are especially vulnerable.
- Human-related threats include cars, pest control efforts, and fire hazards caused by squirrels chewing on electrical wires.
3. Diet and Food Availability
- Squirrels rely on a well-balanced diet consisting of nuts and seeds from trees, bird eggs, and fungi.
- Food caches help squirrels survive harsh winters.
4. Breeding and Survival Rates
- Female squirrels give birth twice a year during two breeding seasons, in late winter and summer.
- Newborn squirrels and baby squirrels have a high mortality rate due to the many beasts of prey and environmental dangers.
- The mother squirrel plays a vital role in protecting and feeding her young squirrels. Baby squirrels live in the nest until about 6 weeks old when they start to come out to explore their surroundings.
5. Average Life Span of Squirrels in Captivity
Pet squirrels can live much longer than their wild counterparts. With proper care, pet squirrels can reach a life expectancy of 20 years, as they avoid predators and receive consistent food and medical attention.
6. How to Prevent Squirrel Infestations
Squirrels in Toronto build nests in trees, chimneys, attics, dryer vents and other sheltered areas. To prevent squirrels from invading your home:
- Use exclusion techniques like sealing entry points.
- Trim overhanging tree branches near your homes roof.
- Avoid leaving pet food and other food sources outside.
- Forget DIY methods and try to avoid feeding and human interaction.
- Contact a professional squirrel removal Toronto service if necessary.
Conclusion
The lifespan of a squirrel depends on its species, habitat, and exposure to threats. While wild squirrels often face challenges that shorten their life expectancy, those in safe environments with ample food availability can live longer. Understanding these factors can help in both appreciating these bushy-tailed creatures and implementing effective pest control strategies.
