In this case the still life was the bird. Back in the late spring, I looked out on the deck one day and saw a mourning dove just hanging out. It was, in fact, a juvenile dove (you can tell it’s not a full adult because it’s all gray, and not the slightly brown color of adult doves).
It just sat there while I took its picture through the glass door, and for quite a while afterward. Nothing better to do, I guess.
