caption: The image shows three common mergansers swimming in the ocean on a sunny day, with the sun glistening off the water's surface. The birds are swimming in a line, with one in the middle and two on either side. The colors of their feathers are a mix of white, black, and brown, and their beaks are a bright yellow. The sun is shining brightly, reflecting off the surface of the water and creating a beautiful contrast between the blue of the ocean and the white of the birds.
