Andy and Kip embark on another wild adventure to North America in search of the animals that live among whitebark pine trees. After seeing a squirrel and catching a glimpse of a bear, Andy flies with a bird called the Clark's nutcracker, watching as it picks a pine nut and then busily buries it in readiness for the winter. Amazingly, the Clark's nutcracker can bury thousands of pine nuts in this way and remember where they all are.
