A black swan (Cygnus atratus) is observed swimming in a body of water, adjacent to a concrete embankment, within the city of Sandanski, Bulgaria. The swan, positioned in the lower-center of the frame, faces towards the left, with its head slightly angled towards the viewer. It possesses entirely black plumage and a distinct, prominent bright red beak with a white tip. Small, dark eyes are visible. The water surface exhibits minor ripples and contains several small, light-colored particulate objects. A rough-textured, grey concrete edge forms a diagonal barrier across the lower left quadrant of the image, separating the water from an unseen terrestrial area. No other subjects or actions are present.
