Bird Intelligence Quiz – Not So Bird-Brained

Calling someone bird-brained once meant they were not clever, but research shows many birds are remarkably intelligent. Crows, ravens, jays, magpies and parrots can solve problems, use tools and remember the past.

New Caledonian crows make hook tools, rooks solve water puzzles inspired by Aesop's fables and magpies recognize themselves in mirrors. Scrub jays plan ahead and hide food when no one is watching.

Bird brains are small but packed with neurons, especially in crows and parrots. Studying bird intelligence helps scientists understand how intelligence evolved separately in birds and mammals.
