A black swan is floating on a greenish water surface, surrounded by gentle ripples. The swan bends its neck and uses its red beak to preen its feathers on its back. The swan continues this grooming behavior, moving its beak along its back and sides. The swan's head remains bent as it meticulously cleans its feathers, creating small ripples in the water around it. The swan's head starts to rise slightly as it continues to preen, but it still keeps its beak close to its feathers.
