Woodpecker

Woodpeckers are a diverse family whose familiar trunk-climbing forms use stiff tail feathers for support and bills for probing or chiseling. Their tongues can help reach hidden food, with structures differing among species. Drumming advertises presence or territory and is not simply the sound of feeding. Many excavate nesting holes later used by other animals. Not every woodpecker feeds primarily on wood-boring insects or spends all its time on trees.
