Preparing a woodpecker for winter.

First, he finds a dead tree and starts making holes for the acorns. Each hole is made very thoughtfully, because if the hole is large, other birds can easily steal the acorn. If the hole is narrow, the nut can break and deteriorate. By the end of summer, the woodpecker's "jewelry" work ends, by this time the acorns ripen and take their places in the tree. The trunk of a large tree can hold about 50,000 acorns, allowing the bird a satisfying winter.
