Just as I arrived the Dipper was back at the Bridge, I'd not expected to see it. I watched it for maybe 5 minutes and then it suddenly flew strongly downstream and disappeared around the bend in the river. I suspect that will be it for a while. I immediately set to and got on with filling in the sketch below. There was also an Otter which I had a brief view of. Always nice to see, but I worry for them, they are so vulnerable to persecution.
