Incredible Memory

Clark’s Nutcracker is famous for its extraordinary spatial memory. Every fall, it collects and hides tens of thousands of pine seeds—especially from whitebark pine trees—in caches (little storage spots) scattered across vast mountain terrain. What’s amazing? It can remember up to 70% of those caches months later, even under deep snow.

How It Works:

• Each bird stores 20,000 to 30,000 seeds per season.

• Seeds are hidden in thousands of small stashes across mountain slopes, often over 100 square miles.

• The bird uses visual landmarks and an internal GPS-like system to relocate its food.

Ecosystem Hero

Not only do these birds feed themselves with stored seeds, but they also play a critical role in forest regeneration. Many of the seeds they forget grow into new trees. In fact, Clark’s Nutcracker is essential for the survival of whitebark pine, a keystone species in high-elevation ecosystems.

Built for the Mountains

These birds are:

• About the size of a jay (11-12 inches long)

• Pale gray with striking black and white wings and tail

• Highly social and intelligent, often seen working in pairs or small groups

Fun Fact:

Clark’s Nutcracker has a specialized pouch under its tongue that can carry up to 150 seeds at a time—perfect for making long trips to store food.

Think of Clark’s Nutcracker as nature’s mountain librarian—organizing, storing, and retrieving knowledge (seeds!) with impressive accuracy.
