A male mallard duck swims through murky water filled with floating debris, likely leaves and plant matter. The duck has the characteristic iridescent green head of a mallard, with brown and black plumage on its body. It is swimming from left to right in the frame, creating ripples in the water. The water appears dark and somewhat stagnant, with a scattered distribution of light-colored specks, possibly foam or tiny insects. The lighting suggests it is daytime, with sunlight likely reflecting off the water's surface, creating bright spots and highlights. The overall impression is of a natural scene in a body of water, possibly a park or a less-maintained canal, with the duck being the sole living subject. There is no visible text in the media. The location context of Saint Petersburg, Russia, might suggest this is a common sight in the city's waterways during warmer months.
