The Cognitive Mechanisms Underlying Episodic-Like Memory in Scrub Jays
Quick fact
Florida scrub jays preferentially recover perishable food (like worms) before non-perishable (like peanuts), and only when enough time has passed that the worms would spoil—a stunning integration of what, where, and when.
Why this is interesting
Imagine remembering not just where you hid something, but exactly when you hid it and what it was—that's a mental time-travel trick once thought uniquely human. Some birds, like the Florida scrub jay, do it every day to find their hidden snacks.
