Years ago I was pass shooting doves at the edge of a pasture in which an old bus (not a school bus) had been parked and abandoned. I was positioned 50-60 yards from the bus when I heard what sounded like a flush followed 2 seconds later by a very loud thud. Upon investigation I found a bobwhite quail with a broken neck; the bird had somehow managed to fly full throttle into the large windshield of the bus. I placed the unfortunate bird in the bag with my doves.
