Fact: Woodpecker, Doctor of trees

Did You Know?
Woodpeckers tap and peck on tree trunks with their beaks as a form of communication and as a method of locating and accessing insects under the bark or in long winding tunnels within trees. Some woodpeckers have discovered that metal gutters or siding can work like a loud drum in order to communicate with other birds.
Woodpeckers do not damage their brains from the tapping and pecking because the force generated does not pass through their braincase. The force travels along the bird's upper jaw, which connects below the brain, and allows shock to dissipate through the bird's entire body. Only a slight force reverberates back into the thick cranium and is easily absorbed.
