Study Notes
Acorn Woodpecker Behavior
- Acorn woodpeckers in Carmel Valley, California, engage in a behavior called hoarding.
- Hoarding involves collecting far more food than needed for the winter.
- They create storage units in dead trees by pecking holes and stuffing them with acorns.
- One extended family of acorn woodpeckers uses a single oak tree as a granary.
- The granary tree has over 10,000 holes.
- Woodpeckers can gather over 100 acorns per day, but can only carry one at a time.
- Woodpeckers can travel up to 12 miles per day in search of acorns.
- Acorns must fit snugly in the holes to prevent them from falling out.
- Predators, including birds of prey, prey on woodpeckers, with a mortality rate of 20%.
- Ground squirrels raid acorn storage sites.
- Food spoilage is a threat to the acorn supply, requiring overstocking to prevent migration in search of alternative food sources.
- Dropped acorns regenerate oak trees, creating a closed-loop cycle for the acorn woodpeckers.
