Woodpeckers: Drilling Holes and Bagging Bugs

Woodpeckers examines a bird often seen clinging to a tree trunk and striking it with its beak. It explores why woodpeckers drill into trees, what they eat, and how they can tap for long periods without getting headaches. The book draws on what scientists have learned about these birds and their behavior. It also identifies woodpeckers through their characteristic tree-trunk behavior.
