An adult seagull stands on a textured, light-colored stone seawall, positioned slightly right of center in the foreground. The bird faces left, its head angled forward, displaying white plumage on its head and underparts, a grey mantle, and black wingtips. Its beak is yellow with a red spot on the lower mandible, and its legs are yellow. Beyond the wall, the calm, deep blue-green waters of the Atlantic Ocean stretch to the horizon. In the midground, the coastline of Cádiz, Spain, is visible, extending from the right with a rocky shore and several low-lying breakwaters. Along the coast, urban architecture includes a prominent white, multi-story building alongside older, yellow-toned buildings, typical of the city's historic center and visible from the Campo del Sur promenade. The sky above is clear and pale blue, with faint wisps of white cloud. Bright daylight illuminates the scene, casting soft shadows.
