Woodpeckers, piculets and wrynecks all possess zygodactyl feet (a bird's foot having the first and fourth toes of each foot directed backward and the second and third forward). This foot arrangement is good for grasping the limbs and trunks of trees. The tails of all woodpeckers except piculets and wrynecks are stiffened as the bird perches on vertical surfaces, tail and feet work together to support.Woodpeckers play important role in keeping trees healthy as their diet consists mainly of insects and their grubs taken from living and dead trees, and other arthropods, along with fruit from live trees, nuts and sap both from live trees. All this drilling and tapping adds up to about 12,000 pecks a day.
but
Why do they peck ??????
Woodpeckers peck at trees to disturb the little insects that live in the bark. They then gobble them up. These birds can also use their strong, pointed beaks to hammer at the tree until they have made a hole big enough for a nest.
