Curlew Sandpiper

Calidris ferruginea

The curlew sandpiper is a small wader. It is a long-distance migrant, breeding in the bogs and coastal lowlands of the Siberian Arctic, arriving there in June and staying until August or September. After the breeding season, it migrates south to spend the winter in Africa and along the coasts of Oceania and southern Eurasia, occupying tidal mudflats and saltpans. Source
