Yesterday we had a visitor to our bird table in the small town of Ilkley about 2pm in the afternoon - plain, pale grey/buff colour all over, wings slightly darker than the body, pointy beak, dark eyes, pinkish legs. Smaller than a blackbird, bigger than a robin. Probably starling size. I've never seen one of these birds before. It was after the fat tray and squared up to a wood pigeon! I watched them for a few minutes. It was quite agile and could balance and get at the caged fat balls. I looked it up and it looked like a photo of a nightingale - But I thought these don't come as far north as Yorkshire. Any ideas anyone? Thanks
