Yikes, that stinks that you have a big ole hole in your post. I love the looks of those woodpeckers but they are sure destructive when they decide to go after prey inside a part of your house.
The tree you see in the background is a lovely big producing PECAN TREE. He had started trying to kill it by pecking all the bark off the tree this past spring but I could never catch him at it when DH was home.
So not only was he pecking holes in my house, he was trying to kill my lovely big pecan tree.
