Squirrels don’t always remember where they have hidden all their nuts. Every autumn, the tree squirrel gathers and hides acorns and other nuts. It knows that food will be hard to find during the winter months. It buries small stores of nuts in many different places.
That way, if other animals find and eat some, the squirrel will have others. The squirrel depends on a keen sense of smell to help it relocate the hidden stores. Yet many of the nuts are forgotten or abandoned by the squirrel. Then the nuts may take root and grow into new nut trees.–Dick Rogers
