Woodpecker Images, Facts and Information:
Woodpeckers have strong bills for drilling and drumming on trees and long sticky tongues for extracting food. All woodpeckers nest in cavities. Some species supplement their diets with birds eggs, small mammals, fruits and some suck sap.
In North America the smallest woodpecker is the Downy Woodpecker and the largest is the Pileated Woodpecker. Most woodpecker species are primary cavity nesters that excavate their own nests and their old nests are often used by other birds and small mammals. Most of them live near forests or woodland habitats but a few live in deserts and rocky hillsides.
