Woodpeckers, too, can be confused

When woodpeckers drill into a tree trunk, their skulls can experience mechanical shocks in excess of 1,200 g – hundreds of times stronger than the g-forces which astronauts might experience – and yet the birds do not appear to be in any way damaged, and are apparently immune to headaches. But what would happen to the dynamics of woodpecker drilling if, say, they were to (try to) drill into materials other than wood? Although full a technical description of such occurrences is currently lacking in the literature, visual evidence is available – as provided in a video recently analysed in the study : A mechanical analysis of woodpecker drumming and its application to shock-absorbing systems
