Several weeks ago while scouting the river's edge, my friend and I came across this tree where we watched the woodpecker flying to and from. The light at that time was not very good so we just watched.
Yesterday we walked back to the area and once again the woodpecker was there. We watched as it flew back and forth, sometimes bringing in new nuts, sometimes taking food out of the stash holes.
In addition to holes that were obviously nesting holes, there were smaller ones where the woodpecker was stashing food. Not only was this the nesting tree but a food locker. Observing this only illustrated the importance of leaving dead trees that are being used by woodpeckers.
There are a couple of trees around the house that are dead but are also used for nesting by various woodpeckers. With pleasure, I would definitely forego a pristine, well manicured lawn to leave essential nesting trees.
