A solitary black swan (Cygnus atratus) is observed swimming in a murky, brownish-green body of water within Varna, Bulgaria. The swan, positioned centrally, displays black plumage with a prominent red beak featuring a distinct white band at its tip. Its neck is sharply curved downwards, with the head partially submerged, indicating feeding or preening activity. Concentric ripples emanate from the swan's head area. The water surface reflects indistinct vertical elements, possibly bare tree branches or reeds, in the upper portion of the frame. The immediate foreground, at the bottom of the image, consists of a dry, light-colored embankment composed of irregularly shaped stones with visible soil patches between them, suggesting a shoreline or pond edge. No other subjects or objects are present.
