Yesterday I was on my regular morning route over the headland. I was pleased to hear a grasshopper warbler calling from the hedgerow by the (new) campsite. This is where I have heard them in previous years. On my return there was a bloke with his wife and son throwing stones over the cliff above the auk colony and the kestrel nest site at Banc Bach y Rhowyn. I shouted at them twice to stop but it resulted in them throwing more stones.
