Chances are, the mom already had somewhere to take her babies. Since squirrels are constantly on the move, going from bird feeder to bird feeder and even from yard to yard, it’s common for them to have second and third nests located near their main home at varying distances. Squirrels use these additional nests in an emergency situation, for example, when they need to hide from a predator, store extra food, or simply when they get exhausted and want to have a little rest.
