Have you seen my bird?

I'm looking for a bird. Not just any bird. His name is Norden. He has taken a particular liking to my vehicle. For three days running, I've noticed that my car has been adorned with airborne decorations. These have appeared in a consistent pattern, no more than an inch from where they appeared the day before. What I find most intriguing is that there are no tree limbs or wires anywhere near my parking spot... which means that Norden is performing these feats of precision bombing while in flight. While I find him truly amazing, and would venture that he was trained by the folks at Lockheed Martin, I would like to introduce him to a stone I'm saving just for him.
