Birds to compare
Black Turnstone

Red Knot
Calidris canutus
Key differences
Red Knots are larger and stockier, with a straight, relatively short bill. In breeding plumage, they have a brick-red breast and belly, but lack the complex black and white head and back patterns of the Turnstone. Their legs are duller, typically greenish-gray.
Sanderling
Calidris alba
Key differences
Sanderlings are smaller, paler, and have black legs. They are typically found on sandy beaches, running along the water's edge. They lack the rufous and complex patterns of the Turnstone.
