The sun shining through the fountain makes it very misty. If you look at the right edge of the fountain, you can just see through the mist that there is a swan swimming in the lake behind it. At first I thought one of the pair nesting in the river had flown over the weir and down to the lake. But when this swan climbed onto the lake island, I wondered if there could possibly be a second nesting pair in the gardens. And sure enough, there is a swans' nest on this island too.
