Here's why:
* Safety: Having multiple nests provides safety in case one is compromised by predators or weather.
* Nesting Season: During breeding season, squirrels might have separate nests for raising their young.
* Food Storage: Some nests might be primarily used for storing food.
So, the number of nests a squirrel uses can vary depending on factors like:
* Species: Different squirrel species have different nesting habits.
* Location: The availability of suitable nesting sites influences the number of nests.
* Time of Year: Nesting needs change depending on the season and the squirrel's current life stage.
It's difficult to give a specific number, but it's common for squirrels to have several nests for different purposes.
