I have blown this photo up of a bird spotted in the Lake District near Ullswater, flying above place fell I wonder if its an Eagle. In the original photo this is a very large bird about 1 mile away not knowingly photographed at the time, only when looking at the photo on computer at home that night did I realise. Any ideas to what it might be??
Best wishes
