I assume the vultures are following or anticipating the "road kill" generated as plowing and other ag activities ramp up? Or do they literally migrate south because all their natural prey in Kansas are hibernating? There is some evidence that they learn to patrol newly-mowed hay fields and other places where small animals have encountered equipment.
