There was actually two buzzards circling each other when Carole called to me. I came out with the camera and began trying to use the zoom lens as they drifted away. At first I thought the lower one had something in its beak? However as I studied the photos, the raptor's wing feathers look damaged. Perhaps it had been in a fight of some sort.
Some of the creature's flight feathers appear to be missing. I think the pair are nesting by some trees across the Fen, close to the river.
