That’s because turkeys take out the car with them. Whole shebang goes to the morgue.
Ok maybe not the morgue, but they do tend to get nicely lodged in whatever part of the car they get struck by. This is generally the front grill, as they are about 5-year-old size and tend to travel on foot, but they are flying bowling balls and can lodge into windshields pretty well too.
I’ve heard of a number of people hitting them (rural area) and the turkey soup always goes with the car.
