Book 31, Question 107
How do scrub-jays remember where they hid their food?
Scrub-jays hide many nuts and seeds in different places to eat later.
Scientists found that they remember not only where the food is, but also what it is and when they hid it. They go back to the tasty, spoilable items first and save the sturdy ones for later. That is more than just a lucky guess. It shows planning.
