Frequently Asked Questions About Gray Squirrels

Here are answers to some of the most common questions about the backyard wildlife we see so often.

How do squirrels remember where they bury their nuts?

Squirrels use a combination of highly developed spatial memory and mental mapping. They remember the location of their thousands of buried nuts by using landmarks like trees, rocks, and buildings as reference points. This is a cognitive skill, not just a matter of sniffing them out. They also use deceptive tactics, like pretending to bury a nut, to fool potential thieves.

What is the lifespan of a gray squirrel?

The lifespan of a squirrel varies dramatically. In the wild, life is difficult, and the average lifespan is often just 1 to 2 years due to predation, disease, and harsh winters. However, if a squirrel survives its first year, its chances improve. In protected environments or captivity, a gray squirrel can live for more than 10 years, with some records showing individuals living up to 20 years.

Are black squirrels a different species?

No, black squirrels are not a separate species. They are a melanistic color morph of the Eastern Gray Squirrel. A genetic variation causes them to produce an excess of black pigment, resulting in their dark fur. They can interbreed with gray-colored squirrels, and a single litter can contain both gray and black kits.

Is it safe to feed backyard squirrels?

Wildlife experts, including those at organizations like the U.S. Fish & Wildlife Service, advise against directly feeding squirrels and other wildlife. Hand-feeding can cause them to lose their natural fear of humans, which can put both them and people at risk. Congregating at feeders can also facilitate the spread of diseases, like squirrel pox. Furthermore, it can make them dependent on an unnatural food source and lead to conflicts with neighbors. The best way to help is to cultivate a wildlife-friendly yard with native, nut-producing trees like oaks and hickories, and to provide a clean water source.
