talking of the foghorn, I noticed that the gap in the fence has been repaired. No more viewing from the Upper Circle. :C
There were some workmen up there a month or two book who were saying this was going to happen. They also told me that if anything happened to me while I was in the foghorn then it was my own fault. I was truly chastened by that.
Black Guillemots breed along the coast in northeast Scotland but only in small numbers so are not normally very easily encountered. They get commoner further north.
