Saved Nuts<br>The pine cone fell to the ground. A squirrel gathered the nuts. It hid them away for the winter. Another squirrel noticed the nuts. He took the saved nuts.
Pine nuts are a food source for squirrels who try to store them for winter, but they may need to develop better ways to protect their food from other predators.
