Acorn Woodpecker Facts

Acorn Woodpeckers are residents to the west's oak forests. They live in family groups. Young Acorn Woodpeckers stay with their parents for a few years after hatching. They help raise new young and defend territory. Everyone stores thousands of acorns each year. A single granary tree may have 50,000 acorns stored for winter. Biologists believe the acorns are saved for the harshest of winter days, with the birds catching insects when possible. Their call is a noisy, shrill "waka-waka-waka."
