Have you ever felt like pounding your head against a wall? Woodpeckers actually do this for fun (well, really for food, but they’re pretty much the same thing). A woodpecker has been specifically designed to ensure that it doesn’t give itself a concussion every time it makes its delightful rat-a-tat-tat noises against a tree trunk. Unlike people, woodpeckers have very little fluid surrounding their brians, but instead, the brain is closely surrounded by spongy bone that absorbs impact from the repeated blows. Also, the woodpecker’s eyelids shut every time it pecks so its eyes don’t fly out of its head, an exceedingly useful feature. I find it fascinating how incredibly intricate and delicate the design of the woodpecker is. So many parts of the bird’s anatomy and physiology have to work together to ensure that it can perform its needed actions. God has certainly showed His wisdom and engineering prowess in the woodpecker.Fun Linky-Links:
