- They also eat:
- Insects like ants and beetles.
- Fruits and seeds.
- Tree sap on occasion.
Behavior
- Social Birds: Acorn woodpeckers live in family groups and are highly cooperative.
- Granary Trees: They create “storage trees” by drilling holes into the bark of trees and filling them with acorns. These granaries can have thousands of acorns stored!
- Communication: They are very vocal, making loud calls to communicate with their group.
- Flight: Their flight pattern is a mix of flapping and gliding.
Reproduction
- Nesting: They nest in tree cavities, often in dead trees or branches.
- Eggs: Females lay 3–6 white eggs in a single clutch.

- Hatchlings: Baby woodpeckers are born naked and helpless, relying on their group for food and protection.
Conservation Status
- Current Status: Least Concern (IUCN), but their population depends on the health of oak forests.
- Threats: Habitat loss and changes in oak forest ecosystems can impact their numbers.
Fun Facts About Acorn Woodpeckers
- Nature’s Hoarders: They can store thousands of acorns in a single tree! Some granaries are used for generations by the same family group.
- Team Players: They are one of the few bird species that work together as a group to raise chicks.
- Unique Flight Call: Their call sounds like they’re laughing, which is why they’re sometimes called “clown-faced woodpeckers.”
- Memory Masters: Acorn woodpeckers have an excellent memory and can remember exactly where they’ve stored their acorns.
- Colorful Faces: The bright red crown and white patches on their faces make them stand out among other birds.
