On a cold March morning, a Clark’s Nutcracker drops to the ground, drives its bill into the soil and removes a pine seed. Then quickly it removes three more. It flies a short distance and repeats the procedure. Another food cache, and five more pine seeds. It will make a few more stops before returning to its nest to feed a hungry bunch of nestlings. The nutcracker hid these pine nuts the previous fall. How does it remember where they are?
