Acorn woodpeckers are famous for storing massive quantities of acorns and other nuts in individually drilled holes in multiple "granary" trees. These granaries can hold more than 50,000 nuts! 😯 The acorns are tightly wedged in their holes so that other animals are unable to remove them. As the acorns dry, they begin to shrink, so the woodpeckers periodically check their supply and move loose acorns to smaller holes. These caches of food are insurance against years when the natural crop of tree nuts is poor.
