There is a duck pond outside our window. There is a white gander and some younger ones who turn upside down like little wind-up toys. They flip upside down to look for bugs under the water, their little feet still paddling the air, and then flip back up to shake off the water. Water puddles on their feathers like oil. I could watch them all day especially when the gander gets after them for being naughty. But what naughtiness they do I am uncertain.
