Like the iconic Dylan, the woodpecker is an icon of the avian world. Perhaps this is due to the fact that it makes its presence well known with its often hard to ignore hammering, but there is more to this wonderful Picidae than meets the ear. Woodpeckers play an important role in forest ecosystems and are often a good index of biodiversity and health within a forest.
So next time you listen to Mr. Dylan or hear the Heavenly Hammering of a woodpecker, remember how important that sound really is. It is the song of a healthy and diverse forest ecosystem, and music to appreciative ears.
