“I’mma stab the bugs out of this tree with my face-knife!⁣” We all need a hobby. But does all that pecking lead to a nasty headache? A woodpecker’s anatomy is specifically designed to absorb the force of banging one’s head into the side of tree which prevents the woodpecker from getting injured. Its specialized beak and skull direct most of the energy associated with this force into the rest of its body. This protects the brain and prevents concussions or injury when pecking up to twenty times per second and 12,000 pecks per day! What the peck!!?! More fun facts, you say? Woodpeckers have zygodactyl feet. Zygo what? That means they have two toes in front and two in back, perfect for climbing and gripping onto a tree trunk. Woodpeckers also have advanced hearing that allows them to detect vibrations from bugs moving beneath the bark of trees, so they can strike with precision. Peck on.
