Historical seasonal record

Look for it

Listen for loud calls in open oak or pine-oak woodland, then scan large trees for a granary trunk filled with acorns.

Food

Acorns, insects, other arthropods, fruit, sap, nectar, and occasional seeds; flying insects can be especially important when available.

Nesting

Natural nesting guidance

One useful next step

Build for the habitat, not just the feeder.

Open oak and pine-oak woodland, streamside forest, urban parks, and suburban areas where mature oaks are present nearby.

See the yard actions

A good yard is layered

Food helps, but cover, clean water, native plants, and a safe distance from hazards make a more dependable place for birds.

Acorn Woodpecker diet and food

Acorns, insects, other arthropods, fruit, sap, nectar, and occasional seeds; flying insects can be especially important when available.

Seed or suet may be used near oak habitat, but retaining healthy oaks and natural insect habitat is much more valuable.

How to attract it

Food & feeder

Acorns, insects, other arthropods, fruit, sap, nectar, and occasional seeds; flying insects can be especially important when available.

Cover & plants

Open oak and pine-oak woodland, streamside forest, urban parks, and suburban areas where mature oaks are present nearby.

Acorn Woodpecker nesting and breeding

Excavates multiple cavities in large limbs or trees; groups may reuse nest holes for years and use others for roosting.

Acorn Woodpecker behavior and where to look

Family groups defend a granary tree, storing acorns in drilled holes and often sharing roosts and care of young.

Photography

Stay outside the core granary or nest area and photograph from a public trail or quiet yard edge.

What to avoid

Do not seal or disturb an active cavity; protect vulnerable wood siding before a storage problem develops.
