For the past seven years, Zelda and Scott Mallard have hung out at out water feature. We do not know if we get the same ducks each spring. We have witnessed mating at the water feature, but we do not know were they build their nest. On this April day, Zelda was twitching her wings at at Scott. I assume Zelda was flirting with her mate, drawing attention to her sexy blue speculum. I could be mistaken. Perhaps she was just drying her wings. None of my sources mention wing flicking.
