I have to confess to being quite surprised when I saw Dippers on the river late this afternoon. It is almost a culvert and it has been artificially contained to stop the town flooding when the snow thaws further upstream. The boulders are well polished which my very rudimentary geography tells me that in the past , glaciation has taken place. When granite is very polished this is an indication. The water is extremely clear as it has come down from the mountains. I went down with the camera later on and took some really attractive photographs with the pristine water and late sun shining on the water. There was no sign of the Black Redstart that I had see earlier but several Grey Wagtails were flying up and down as well. Considering that we have Grey Wagtails in the brook very close to my house, I hope I am going to see something a bit more exotic!
