Study Notes

Acorn Woodpeckers and Hoarding

Acorn woodpeckers are known for a unique behavior called hoarding.
They collect far more acorns than needed for winter by pecking holes into dead trees, creating thousands of storage units.
These storage units are referred to as granary trees.
One particular granary tree had over ten thousand holes, showcasing the immense effort involved.
An acorn woodpecker can collect over one hundred acorns a day, making one trip per acorn.
The woodpeckers fly long distances, up to 12 miles a day, to gather acorns.
Acorns must be securely pounded into the holes, and a poor fit can lead to loss.
Predators like birds of prey pose a threat, taking one in five woodpeckers.
Ground squirrels steal acorns from the woodpecker's hard-earned storage units, causing annoyance and competition.
Overstocking is necessary due to the risk of acorn rot and to avoid migrating for food.
The dropped acorns from the hoarding process contribute to the regeneration of oak trees, creating a cycle of life.
