Attack of the Robin

Ok so we have this robin that lives outside our sun room. He frequently wakes Mirra and I up, the boys sleep right through it, by running into the windows over and over again. I know it sounds crazy but that is why I recorded a few seconds of it. This thing will fly from a tree close to the window and hit somewhere on the sunroom two or three times and then go back to the tree sit there for a few second and do it all over again. Today though he started on the sun room but ended up going to the other side of the house and started on a new window. It scares the kids to death. It is really kind of freaky,
