caption: The image shows three hooded mergansers swimming in the water, their distinctive hooded feathers glistening in the sunlight. The birds have a distinctive white head and neck, with a black and white striped pattern on their wings and a white patch on their chest. Their beaks are a deep brown color, and their eyes are a bright white. They are swimming in a line, with one in the middle and two on either side of the line. The water is calm and still, reflecting the sky above them.
