	abstract = {To assess whether reducing visibility would also reduce aggression in farmed bulls, we put 2 newly-formed groups of 20-month old Friesian bulls into two types of paddocks. Those animals in paddocks where visibility was obscured by pine trees showed about one-eighth the level of aggression as those put into a bare grassy paddock. It seems likely that vision is a modifier of aggression in bulls as in some other species.},
