Migration of Spoon-Billed Sandpiper
Spoon-Billed Sandpiper migrates down the Pacific coast through Japan, North Korea, South Korea and China, to its main wintering grounds in South and South-East Asia, where it has been recorded from India, Bangladesh, Sri Lanka, Burma, Thailand, Vietnam, the Philippines, Peninsular Malaysia and Singapore.

Spoon-Billed Sandpiper as Endangered Species
Spoon-Billed Sandpiper 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. The protected areas of Spoon-Billed Sandpiper in its staging and wintering areas include Yancheng in China, Mai Po Marshes in Hong Kong and Point Calimere (Point Calimere Sanctuary, Tamil Nadu) and Chilka Lake in Odisha.
