That s the way a woodpecker s head works, like a jackhammer, chopping a hole in a tree trunk. The world has 200 species of woodpeckers. Nine species live in Minnesota.
Woodpeckers are an important part of the forest.
They hunt for insects by drilling holes in dead wood. Many of the insects they eat could harm trees. The nesting cavites woodpeckers dig in trees become homes for other creatures - bluebirds, chickadees, and squirrels. It could have been a woodpecker banging on a tree to scare away other woodpeckers. Most woodpeckers choose to live in a certain part of the woods, and they try to keep other woodpeckers out of their territory by drumming fast and loud.
