Northern Flicker - when we first moved into our house 15 years ago occasionally we would hear this terrible banging sound coming from the metal vent on our roof which was amplified through our wood stove. After awhile we figured out who was doing this and I caught him again last week. This might as well be a mug shot because he looks guilty to me. I find it kind of amusing unless I'm trying to sleep. Taken near Olympia, Wa.
I really appreciate the comments!
