I was coming home earlier today along a quiet country lane and noticed a few starlings flying over, they were joined by a few more, then even more. I noticed in my mirror that there was a black cloud behind, it turned out they were also starlings. It was a clear road so I stopped for a good look and was treated to a show of swooping, swirling, twisting and all sorts of wierd shapes, there were thousands of them. I watch them for 20 minutes then in a flash they were gone. What a fantastic show and something I have not seen live before.
