5. They Have Sharp Tail Spikes

Apart from its beak, the woodpecker has another part that it uses for defense against potential threats. They are completely resilient and are very good at climbing trees. As they are birds that are designed to adapt to a tree trunk climbing lifestyle, the woodpecker’s tail has sharp spikes that allow them to dig into the bark of a tree. While it uses its claws, its tail acts as a third leg to keep itself secured, similar to how we set up tripods.
