Acorn Woodpeckers

Stanford University, Palo Alto, CA: A family of Acorn Woodpeckers is hard at work, storing acorns for the winter.  They carefully pick acorns from oak trees and fly them to nearby storage/granary trees which sometimes hold up to 50,000 acorns.  The woodpeckers bore holes in the trees with their beaks to store their acorns in.  Some of the trees have so many holes that you can see right through the trunk and limbs!  In some places, it looks like the tree is about to snap in two._
