caption: The image shows two white swans standing next to each other in the water. One of the swans is a mute swan, with its white feathers glistening in the sunlight. Its long neck is curved gracefully, and its beak is slightly open, as if it is about to take flight. The other swan is slightly smaller, with a lighter shade of white on its back. Both swans have a peaceful expression on their faces, and the water around them is calm and still.
