Dipper ripples

Another grey day of muted colours so textures become more important. 
This picture started out trying to get a confirmation ID on a dipper. To my naked eye there was just a brown dot, with perhaps a white flash, on the other side of the Derwent River. Two or three clicks later showed it blurry but enlarged, a definite dipper, feeding around the skirt of a small rock. 
This one I nearly deleted but looked again at the water patterns and thought it was more like an abstract wall hanging. 

Just take my word, the blob's a dipper.
