This Old House (is getting destroyed)

 Yup.  Flickers, occasionally seen around my bird feeders, have decided that the front of my house would make a great home.

Discovered this while unloading my car the other day, when I heard a knock-knock-knock behind me. There he was, drilling away at the third hole, furthest to the right. He flew away, but then the female came out of the middle hole. Turns out it's also a federal crime to interfere with an active nest since they are a protected species. Thankfully it's not an active nest yet, so some a Powershot staple gun and some wire mesh seems to have taken care of the problem. Now I just need to figure out a repair before something that can get through the mesh moves in.
