We had one of those, too, when I was growing up...t'would bang on everyone's drain pipes at five AM. Our closest neighbor is a sharp shooting ex-Marine. We all supported his actions...
My buddy Jeff (also a jarhead) shot a woodpecker that was bangin' on his house...it dropped down in the 2nd story raingutter...he didn't think anything of it till the next day, when they heard a ruckus and bangin' on the house...seems two crows stumbled across the woodpecker and were fighting over it as they ate it...
