Acorn Woodpeckers Can Store As Much As 50.000 Acorns in a Single Tree

An average granary tree usually holds thousands of acorns. The woodpeckers use every little square inch on the tree, which can be covered in holes from the bottom to the top. The most holes ever recorded on a granary tree were 50.000, which is the result of work done by multiple generations of woodpeckers.

Their evolutionary strategy has seemed to pay off: acorns are perfect for the winter months due to their rich fat content. And although no other bird hoards food on such a grand scale as the woodpecker, this habit is indeed effective for surviving cold weather without having to migrate to warmer climates.
