Apparently yesterday the last of the 888,246 was added, to commemorate the lives of British and Colonial forces lost in the First World War. It seemed appropriate to be there on 11 November.
About 200 years ago, a century before the First World War, Alexander Wilson, the Scottish naturalist living in north America, estimated that he had seen almost three thousand times as many Passenger Pigeons as that figure, over two billion, in an afternoon in Kentucky. A century later there were none in the wild and only a few in captivity until the last, Martha, died on 1 September 1914 – at a time when almost no-one imagined the human carnage that would result from the war that had recently started in Europe.
As Plantlife points out, poppies are under threat too, these days.
