Yesterday while walking from the dining room to my apartment building I heard a woodpecker. I paused and look up in a tree but did not see him. I took a few steps and heard him again and I stopped and looked. I thought he wants me to see him. After a minute or so I spotted him about 30 feet up the side of a tree. He commenced his rat-a-tat-rat-a-tat-rat-a-tat pecking as I stood there watching and listening. Then he moved about 90 degrees to a new position on tree but hit a soft spot and though his beak was moving in and out, or up and down, there was no noise. He flew away and I walked on to my apartment.
