A solitary black swan is observed resting on one leg at the edge of a calm body of water in Jiangjin, China. The swan exhibits dark plumage, with its head tucked back into its dorsal feathers. Its single visible webbed foot is submerged in the light gray-brown water, casting a distinct shadow on the water's surface, along with a blurred reflection of its body. The water surface shows minimal ripples and scattered small white foam particles. The bird stands adjacent to a defined concrete or stone bank edge. The land portion of the bank displays a mixture of dry, light-brown grass and patches of vibrant green, low-lying ground cover. A single fallen brown leaf is visible on the drier grass in the foreground. No other subjects or interactions are present in the scene.
