BACKYARD SECRET: NO INJURIES FOR PILEATED WOODPECKER
backyardwildlifeconnection by Terry W.Johnson
When a pileated woodpecker is drumming against a tree, it generates a huge amount of force. A human would experience the same amount of force if they were moving at a speed of 16 mph and smashed headfirst into a wall.
If this happened to one of us, we would undoubtedly suffer a number of serious head and neck injuries including a concussion. Yet the pileated woodpecker can drum against trees 17,000 times per day without suffering any injury whatsoever.
