I've had birds hit the window in a couple of office buildings I've worked in. But the weirdest thing happened when I was sitting in the passenger seat of a parked car one time, waiting for the driver to come back from inside the store. It was an old car and it had the long external antenna popping up from behind the hood right in front of me. As I sat there, a bird came swooping by, straight into the antenna. He bounced to a stop on the hood of the car, sat there for a few seconds shaking his head as the antenna slowly twanged back and forth, then got up, walked around in a circle to get his bearings and flew off. It was like a cartoon.
