caption: The image shows two shelduck ducks swimming in the water, their feathers glistening in the sunlight. The water is still and clear, allowing us to see the birds' reflections on the surface. The ducks are a deep brown color, with a white patch on their chest and a white head and neck. They have long, thin beaks and webbed feet, and their wings are tucked in close to their bodies as they glide gracefully through the water.
