Acorn Woodpecker (Melanerpes
formicivorus), Family Picidae |

Explanation: Here's what Acorn Woodpeckers do! They collect massive numbers of acorns from oak trees. Then they deposit them in "granaries" ... usually softwood trees such as pines, in which they have drilled massive numbers of tiny cavities in which to stash their acorn prize, saving them for later. The
acorns are squeezed into their tiny homes so that other animals cannot extract
them.
They are known to use power poles and telephone
poles as nest sites, hammering cavities into the tough dried wood ...
sometimes causing failure of the structures and causing power companies having
to replace the poles ... perhaps a small price to pay for helping conserve
this most unique species.
