I came across this nest just by luck, I had seen one of the swans but lost sight of it whilst taking some shots of other water birds, I then got a flash of white through the reads, twenty yards down the bank I looked back and bingo, at first I could only see one adult and then to my delight it stood up to change places with the one I had seen on the water earlier. I have left the Original images so you can get a look at the signets also look at the adults looking under the standing adult, I guess to make sure all the kids are staying in the nest.
