A white swan stands on a green grassy bank along a waterway in Tomar, Portugal. The swan, predominantly white, features an orange bill with a prominent black knob at its base. It is oriented towards the left of the frame, with its neck curved backward and its head turned over its left shoulder. A single black webbed foot is visible on the grass. The bank slopes down to a body of green water, which exhibits ripples and reflections of sunlight. A distinct shadow is cast beneath the swan onto the grass, indicating direct illumination. The immediate shoreline where the grass meets the water shows exposed soil and small irregularities. No other subjects or interactions are visible.
