07 july 2024, Basse Yutz, Yutz, Thionville Portes de France, Moselle, Lorraine, Grand Est, France. It is summer. On the wall of a sand pile that a scree has recently made almost vertical, two Sand Martins have perched on a growth in the sun. In the background, a third swallow, in the shadow, is nestling against the wall. Its back is turned. They are three juveniles, recognizable by the lighter edging around the wing feathers.
