We have special houses for the woodpeckers and flickers. Unlike songbirds most woodpeckers have two toes facing forward and one facing back. This allows woodpeckers to easily climb and grasp trees and other structures. Woodpeckers move up a tree by hopping and depend on their especially stiff tail feathers to serve as a prop.
They have thickened skulls and powerful neck muscles that enable them to deliver sharp blows without damaging their organs. Their stout, chisel-like bills allow them to bore into wood. The tongue of a woodpecker, often covered with barbs or sticky saliva, can be extended a considerable distance in order to dislodge ants and insect larvae from deep crevices in wood and bark. For storage, the tongue is curled around the back of the head between the skull and skin.
