Hairy woodpecker (male)

These birds forage on trees, often turning over bark or excavating to uncover insects. They mainly eat insects, also fruits, berries and nuts, sometimes tree sap. They are a natural predator of the European corn borer, a moth that costs the US agriculture industry more than $1 billion annually in crop losses and population control. They are also known to peck at wooden window frames and wood sided homes that may house bugs.
