This was one of a group of five juvenile Sanderlings feeding up before their next leg of migration. This can be a tough spot as the beach slopes down to the water's edge, making of uneven images even if level, but when the subjects get right at the water's edge then things straighten up quite nicely.
Canon 7DII + 500mm f/4 II + 1.4TC III, manual exposure, evaluative metering, 1/3200s., f/5.6, ISO 800, natural light, handheld, small crop for comp, a few bright specks in the sand spot-removal tooled away.
Nice look at this feeding individual. You got him with the beak just above the ground, so that's great; the shot loses my interest once the beak goes into the mud, but that's totally personal preference. The reddish shoreline is really different.
