I was talking to one of the site operators at Maerdy works this morning and we got onto the subject of birds, as you do, and he told me about this large bird of prey that landed here back in the summer( Here are the pics his colleague took). Neither of them thought it to be a Buzzard, it looked larger if anything. My first thought was immature Goshawk but the supercilium is a bit indistinct and the feathers on its wings look a little uniform in colour. Incidentally this is the exact location where I found a predated red legged Partridge last May. Any ideas?
