Sanderling

Calidris alba

Sanderlings are small, lively birds that love to run along the beach. They have fluffy white feathers and are often seen chasing the waves as they search for tiny food in the sand.

Hábitat: Coastal areas

Aspecto

The Sanderling is a small, plump shorebird with a short, stout black bill and black legs. In winter, it is strikingly pale grey above and pure white below, appearing almost ghost-like on sandy beaches. It lacks a hind toe, giving it a distinctive track and running style.
