Acorn Woodpeckers are social birds that live in noisy colonial groups. The colony works together to harvest and store acorns in granaries, which are commonly drilled in dead trees, utility poles, sides of buildings and live sycamore and oak trees. The granary site is usually near a group of acorn producing trees. Granary maintenance requires a lot of work. Acorns shrink as they dry out and must be moved to smaller and smaller holes. And woodpeckers must constantly defend their granaries from scrub jays and squirrels.
Happy Birding!
