The Spoon-billed Sandpiper (Eurynorhynchus pygmeus) is a small wader which breeds in northeastern Russia and winters in Southeast Asia.
This bird is critically endangered, with a current population of fewer than 2500 – probably fewer than 1000 – mature individuals. The main threats to its survival are habitat loss on its breeding grounds and loss of tidal flats through its migratory and wintering range. The important staging area at Saemangeum, South Korea, has already been partially reclaimed, and the remaining wetlands are under serious threat of reclamation in the near future. A 2010 study suggests that hunting in Burma by traditional bird trappers is a primary cause of the decline.
Formerly classified as an Endangered species by the IUCN, recent research shows that its numbers are decreasing more and more rapidly and that it is on the verge of extinction. It is consequently reclassified to Critically Endangered status in 2008. The population was estimated at only 120-200 pairs in 2009-2010, perhaps indicating an 88% decline since 2002 equating to an annual rate of decline of 26%. Draining of the Saemangeum estuary in South Korea removed an important migration staging point, and hunting on the important wintering grounds in Burma has emerged as a serious threat. This species may become extinct in 10–20 years.
