Woodpecker

Woodpeckers are tree-dwelling birds belonging to the family Picidae. They are recognized by their strong beaks (used for drilling into wood), long, sticky tongues (used for extracting insects), and zygodactyl feet (two toes forward, two back) adapted for clinging to tree trunks. Woodpeckers are found worldwide (except Antarctica), inhabiting forests and woodlands. They primarily feed on insects found within trees, but also consume fruits, nuts, and tree sap. Woodpeckers communicate and mark territory through their drumming sounds. They excavate cavities in trees for nesting.
