Him again

Walking back from the Stockbridge Market, I bumped into a friend (having apparently missed Acronymphomania at the market).
Managed to get fairly close by keeping very slow and silent, but just after I took this, a family party wandered past and the mother asked what I was looking at. When I whispered "kingfisher", she shouted to her son, who had wandered about 50m ahead, "DEREK!!! There's a kingfisher here!!!"
Last I saw of the little blue birdie, needless to say...
