Up to 150 at a time, a fifth of its entire body weight.
Then it flies as much as 15 miles away, and drills the nuts into the ground in sets of ten, placing a stone on top of the stash 1 to mark the site.
It goes back for more and more. Over the autumn, a single bird can bury 30,000 nuts across an area of 100 square miles. When the winter comes, it will manage to remember the location of a staggering 2 70% of these seeds, even when hidden beneath the snow. But as the Clark’s Nutcracker remembers its way into surviving the winter, it becomes the whitebark’s greatest ally 3.
Although its feat 4 of memory is extraordinary, for every thousand seeds it buries, it still forgets 300. From all those missed seeds carried far and wide across Yellowstone, new whitebark pines will germinate 5 next spring.
