Spoon-billed Sandpiper (Eurynorhynchus pygmeus) is a critically endangered species (IUCN redlist 2013). It’s breeding in Russia and wintering down the western Pacific coast through Russia, Japan, North Korea, South Korea, mainland China, Hong Kong (China), Taiwan (China) and South-east Asia including Myanmar, Thailand and Vietnam. 

Mekong Delta is one of key remaining SbS wintering sites. The survey done by Birds Russia collaborated with University of Science in Ho Chi Minh city in 2011 had recorded up to 8 or at least 5 birds (Vladimir et al., 2012). In additional, by personal observations, there was 1 bird recorded in Can Gio area in April 2010 (Nguyen Hoai Bao) and another one record also in Can Gio in October 2010 (Jonathan Eames). An older survey in 2000 by Moores, N. and Nguyen Phuc Bao Hoa has reorded up to 5 individuals in Ba Tri area. 

This one-week survey therefore could a desirable data to support mornitoring SbS as well as waders population wintering in Mekong delta, especially at the IBAs along coastal in the southern Vietnam.
