I'm told that the threat posed to agriculture by the rising rabbit population in the 50s and 6o's was met with the introduction of myxamitosis. This disease had a devastating effect on rabbits and so dependent are buzzards on rabbits for food that there was an almost immediate drop in buzzard numbers by up to 50%. Now the rabbit population is less impacted by myxamitosis then the numbers of rabbits in the area has grown and hence the increased number of Buzzards.
We went for a walk round Bryn Pydew and through the fields and trees round the back Bodysgallen Hall, at the weekend, and came across two buzzards in the fields feasting on a dead rabbit. They were most reluctant to move as we approached and we managed to get within 10 or 15 feet of them before they flew into the tall trees.
