Percentages: Feeding the Nutcracker

The Clark's Nutcracker uses its remarkable memory to store pine nuts for winter survival. Each autumn, it hides up to 30,000 nuts across Yellowstone, ensuring it has enough food despite a 70% retrieval success rate. The unrecovered nuts grow into new pine trees, supporting future generations of nutcrackers.
