How long do squirrels live? The answer depends on whether they survive their first year
Squirrels are some of the commonest animals in parks, gardens and backyards. You might see them scuttling across a fence or racing up a tree trunk or digging through leaves for food. They are quick, clever and endlessly busy, which is probably why so many people wonder how long they actually live.
The answer is not the same for every squirrel.The lifespan of a squirrel depends on the species of squirrel, its environment and its ability to avoid predators, disease and human hazards.Some squirrels may only live a few years in the wild, while others can survive much longer if conditions are safe.
Typical squirrel lifespans
Among the most common species, the eastern gray squirrel usually lives around six years in the wild. In especially favourable conditions, with steady access to food, water and shelter, some have been known to reach 12 years. That is unusual, but it shows how much a safe environment can matter.
Red squirrels tend to live a little less, usually around four to five years.Fox squirrels often survive about three to four years on average, though some can live up to seven years in the wild. Ground squirrels fall into a similar range.
Flying squirrels also have modest lifespans compared with many larger mammals. Southern flying squirrels typically live three to five years, while northern flying squirrels may live four to six years. These are average figures, but they only tell part of the story.
Why many squirrels do not reach old age
One of the biggest reasons squirrel lifespans are shorter in the wild is survival during the first year. That first year is extremely dangerous. For example, gray squirrels have roughly 25 percent chance of making it through their first year in nature. If they survive that early stage, their odds improve significantly.
The main threats are predators. Foxes, coyotes, hawks and owls all hunt squirrels. Young squirrels are also at risk from snakes.Squirrels also die from starvation , disease , and injuries caused by fights with other squirrels over territory or food . Human activity is another big threat . Cars are a big danger , especially for squirrels crossing roads looking for food. Pet dogs can be dangerous as well , and hunting seasons affect their survival in some places . Squirrels are adaptable but face many dangers every day . Lifespan in captivity Squirrels can live significantly longer in captivity , protected from predators and often receiving regular food and medical care . Gray squirrels can live to 20 years of age , and fox squirrels can live to 18 years of age .That is a major difference compared with life in the wild. It shows that many squirrels are capable of much longer lives than their natural environment usually allows. In a protected setting, the biggest threats are removed, which gives them a far better chance of reaching old age.
Of course, captivity is not the same as a wild life, but it does reveal the species’ potential. A squirrel’s body can last far longer than most people assume when it is not constantly battling predators, weather and food shortages.
What you can do to help squirrels
If you enjoy watching squirrels in your yard, there are simple ways to make your space safer for them. During cold months, they may benefit from a natural food supply such as unsalted nuts, seeds and berries. These foods can help them during times when resources are scarce.Many people also install squirrel nest boxes, but squirrels don’t always use them. Many squirrels prefer to make their nests in trees, so providing some shrubs and natural cover nearby can also help.
