You might expect to hear sublime singing in a cathedral, but last Christmas I was surprised to hear the melodious notes of a robin in Winchester Cathedral. At first, I thought it was my imagination, but then I saw the little bird perched on the magnificent carved choir screen. It paused, head cocked, watching me with curiosity. I hoped it would sing for me again, but it flew away, before landing nonchalantly on the back of a chair. It behaved as if it owned the place.
