At school we used to regularly play the old game of ‘jacks’, with a small, hard, rubber ball and little metal jacks. I was good at it, finding an ability to scan the way that the jacks had fallen and assess the best way of scooping up two or five or whatever number I needed. This morning looking at the mob of little brown birds, sparrows, chaffinches, siskins…and the obligatory ring dove, busy on the grass, I realised that I was trying to count them using the same technique. The only problem is that they won’t stay still. Has the Great Garden Birdwatch ever considered how difficult they’re making our lives?
