Now you see it..........
......now you don’t. This Cormorant spends about three times as long under the water as it does on the surface.
It comes up at a different place and by the time you have zoomed and focussed putting your finger on the shutter button is the signal for its next dive.
The result is that I have several shots of empty water.
The extra is a Weeping Flowering Cherry in full blossom.
