caption: The image shows a family of four ducks swimming in the water together, with one of them being a ruddy duck. The water is still and clear, allowing us to see the ducks' ruddy feathers glistening in the sunlight. The ducks are swimming in a line, with the largest one in the center and two smaller ones on either side. The ruddy ducks have a reddish-brown body with a white patch on their wings and a white head and neck, and their beaks are a light brown color. They are all facing the same direction, creating a peaceful and serene atmosphere.
