Although there are many different predators that prey on squirrels, not all predators eat every type of squirrel, according to School for Champions. This may depend on the area where certain types of squirrels and predators are found. The most common predator of the yellow pine squirrel, for example, is the long-tailed weasel, but this may differ for other species of squirrel.
There are also other factors that contribute to squirrel mortality. One of these is weather. Cold snaps in early spring can limit the availability of buds that squirrels depend on for food. In addition, droughts throughout the year can limit the availability of nuts and acorns that squirrels depend on for food in the fall.
Another factor that contributes to squirrel mortality is motor vehicles. Motor accidents with squirrels are most common in the spring and fall when there are many young squirrels.
The average squirrel lifespan is six years, though many squirrels die within their first year, according to School for Champions.Learn more about Zoology
