退潮时，一只银鸥站在石头墙上，背景是牡蛎养殖场。

p side view of a herring gull standing on a mossy stone wall or harbour structure in bright sunlight. The bird faces right with yellow beak and pale eye clearly visible against soft white and grey plumage. In the blurred background a large oyster farm is exposed at low tide with rows of oyster beds and wet sand channels visible. Orange lichen covers the stone beneath the gull. Perfect for coastal wildlife, nature, seabird, aquaculture and Brittany landscape projects.
