I've got a resident woodpecker that has decided that the edging along my roof is a great place to find snacks each morning. It is really annoying to hear the sound of a small hammer, plus he's putting holes in the wood. I don't see any signs of rot or insects so I'm not quite sure why he does this.
I've been tempted to remove him on a permanent basis, but he is a pretty sucker and he does get bugs out of some of my trees (well, either him or relatives of his). I've heard that you can put up plastic "flags" to discourage them. Does this work? Any thoughts?
