The video shows a duck swimming in a pond full of koi and other fish. The duck is mostly black with some green iridescent feathers on its back. It has a distinctive white patch on its face and a red beak. Someone throws food, possibly fish food pellets, into the water, and the duck dives its head under the surface to eat. The koi and other fish are of various colors, including red, orange, and black. The water is slightly murky.
