I didn't photograph the two shags together, because I was in the flow of the movements by then. But at the end I was just in time to catch the second shag, spreading her wings once more, but this time as a prelude to flight.
What variety and change I'm discovering, simply by doing the same practice each morning in the same spot.
PS I took a walk later, and bought fish for my dinner. This felt perfect, after moving in unison to the fish-eaters this morning. I hope the shags had a good feed too.
PPS Some people have had trouble recently, posting comments on blogspot sites. I've removed the word verification, hoping to make it easier for you all. Do let me know if you are still there!
