The video shows a swan swimming in the water at night. The swan is white and is seen swimming in the water. The water is dark, and the swan is illuminated by a light source, possibly a flashlight or a spotlight. The swan is moving slowly and gracefully in the water. The light creates a reflection on the water's surface, and the swan's feathers are ruffled by the movement. The video captures the serene and peaceful scene of the swan swimming in the dark.
