I took this picture “blind” because I could not see the swan with my own eyes. The nest and swan were almost invisible behind the reeds on the far side of the pond. All I could see was a bit of white. But, I figured,”What else could it be but the other swan?” They are always in pairs, especially this time of year when they are breeding.
So using my super zoom, I aimed at the white thing and took a series of pictures. It was the nest. The camera has far better eyesight than I do.
