Memory Masters: Scrub-Jays remember where they hide food, what they stored, and whether another bird was watching.
The Spy Game: If another jay sees them hiding food, they may return later and move it to a safer location.

They Know Faces: These intelligent birds can recognize individual humans and remember experiences.
