Why Don’t Woodpeckers Get Headaches?

Featured in Ripley's Believe It or Not!

Woodpeckers can peck up to 20 times per second. Do they get headaches?

Their skulls are separated from their beaks, with an air cushion softening blows. They also have a third eyelid that keeps their eyeballs from flying out of their heads.

These features help keep the woodpecker safe. They also have tongues that wrap all the way around their brains!
