It certainly didn’t sound like a Buzzard – more like a seagull with a sore throat, but when it flew over, it certainly looked like a Buzzard! I didn’t catch a photo of it at that point, but I heard it again later on, and despite the strong wind trying to blow me over, I was able to get a couple of photos in focus.
Not the clearest, mainly due to the wind and the distance, but I think these are the best photos I have so far, for seeing the detail on the wings.
