That was the distinctive noise I heard as I walked back to the house from my studio this afternoon. I knew exactly who it was!
I couldn't see him to start with as I was looking up into the trees in our woods, and he was actually quite low down - only about 6 foot up in the tree. I was close to him, but knew he was busy and wouldn't bother with me. So I went inside and got my camera.
His head moves so fast, it's difficult to get a good photo in focus - guess I needed to adjust my camera - but it was pouring down with rain. (Yes, we have rain at last...but that's another story!)
Our arborist just came yesterday to check out the trees. Obviously our friend here thought he should check them out too. Not sure how big he's hoping this hole we get.... I'll have to keep an eye on it.
