The video shows a single duck swimming on a calm, dark lake. The duck is a male mallard with a green head, brown chest, and gray and white body. It leaves a small wake behind it as it moves across the water. The lake's surface is mostly smooth, reflecting the sky above, which is a pale blue color. In the distance, there's a line of trees on the horizon and a small pier with red buoys. The camera angle is slightly above, looking down at the duck as it swims.
