I’ve watched a Red-bellied Woodpecker on this tree on several visits to this area. It is a neck-craning experience due to surrounding trees, but I can’t resist following the sound of the tap-tap-tapping.
The tree he is working on is dead and if you put your hand on the trunk you can feel the vibration as the woodpecker does his thing. I think nesting season is over and doesn’t appear to be finding food, but there must be something attracting him.
Not a great shot, but standing way back and peaking through the leaves there is a view of the large hole being worked on. He puts his entire top half in the hole to tap-tap-tap.
