SCIENTIFIC NAME:Calidris alba POPULATION: 300,000 (North America); global population unknown. TREND: Unknown HABITAT: Breeds on high Arctic tundra; winters along sandy beaches, on tidal flats, and at the edges of lagoons.
Unlike other members of its family, the Sanderling lacks a hind toe, a modification that helps this bird run across sandy surfaces. The ability to run quickly and efficiently on sand is especially important to this species, which forages along the ocean’s edge.
