More Woodpecker facts: hitting a tree-trunk at 18-22 times a second, with an impact 100 times the force that would cause us brain damage, the woodpecker has many special adaptions to protect it. Smoother brains, more tightly packed inside the skull, with less fluid around them, all reduce the movement, vibration and shock the brain goes through on hitting the wood. Spongy bones in the head, and very strong but elastic beaks also reduce the trauma and a special structure attached to their
tongue further reduces vibration. These facts have only been discovered since the invention of high-speed photography, but are being used to develop new materials that should help protect many things, from airplane black-boxes, and sportspeople’s brains, from trauma and damage on impact. Conditions: A cool day with breezes, showers and sunny intervals. Temperature: Max 7- Min 2c.
