Here is a Ruddy Duck, in the midst of a display. There were two males, with the fabulous blue beaks, and two more subtle females. This male was pursuing one of the females. She kept escaping and went near the other male and female. Safety first.
I took this distant family shot zoomed out and saved the identification for today: a family of hooded mergansers. The feathered hoods are tucked back and this is in the early morning.
