Woodpecker

Woodpeckers can peck more than 20 times per second, an estimated 8,000-12,000 times per day.

To prevent brain damage from the rapid and repeated pecking, their very small brain has very little contact with the skull surrounded by a spongy bone.

They can hammer acorns into crevices so tightly that no other animals can remove them.
