Eleven years ago, I devoted an episode of Hooting Yard On The Air to reading out a list of 601 birds, plus an astronomer, a newsreader, 2 jazzmen, 5 film directors, and 34 stars of stage and screen. This recording – hugely significant both culturally and ornithologically – has now been made readily available, split into three parts by dint of YouTubeosity. I strongly advise you lot to listen to the whole thing, repeatedly, umpteen times a day, until you have it committed to memory. You will find it invaluable next time you are leaning insouciantly against a mantelpiece at a sophisticated cocktail party and there is a lull in the conversation.
