The speculum is about the only bit of color on the female mallard. It can appear anywhere from violet to medium blue to turquoise (as seen here), depending on the light. This duck was catching the final rays from the early-setting sun on this winter afternoon. She was probably as astonished as I was finally to see the sun for more than a few minutes at a time.
