Bent Life History
Visit the Bent Life History for extensive additional information on the Acorn Woodpecker.
The Acorn Woodpecker lives in colonies, and several adults may help incubate the eggs in a single nest.
So-called granary trees in which acorns are stored for later use may contain tens of thousands of acorns.
The call is a "waka-waka-waka."
Acorn Woodpeckers will take nectar, and occasionally come to hummingbird feeders. Will also feed on suet and peanuts.
