For a male Ruddy Duck, the ability to impress one or more females determines the number of offspring he can sire. To do this, his overall size is less important than the size of his large feet and long tail. Males also go to great lengths to show off their vivid, sky blue bill, and they have the odd behavior of beating their breast and creating bubbles. In this video we propose that the color of a male’s bill complements the color of the sky for a reason.
