The video shows a mallard duck swimming in a body of water next to a stone embankment. The duck is predominantly brown and white, with a green head, and is moving in the water with small ripples visible around it. The water is dark and somewhat murky, with bits of debris floating on the surface. The embankment is made of large, rough-hewn stones with some visible cracks and variations in color. In the background, buildings are vaguely visible across the water, adding depth to the scene. The overall lighting is subdued, suggesting an overcast day.
