Such a pretty bird, I don't see why you guys are so against them. They eat insects, mostly stay out of the way, are a LOT more attractive than most animals (hippo, rhino, elephant, tarantula/any-spider-ever, etc) and generally spend their entire life singing. Sure, they MAY stuff on your car. You would too if it was socially acceptable to just stuff when you had to stuff. Just be glad they aren't the size of an elephant, those turd-bombs would probably put a dent in your car. Worst case scenario you blast it off with a hose or just take your car through the car-wash.
The bird looks like a chickadee but I can't be certain cause of the video quality. I'm also assuming the chirping in the background IS that bird.
