On October 12th, more than 5 flocks and up to 103 spoon-billed sandpiper were recorded in the high tide. That is clearly the highest number for over 20 years and probably half of the global breeding population!!!
It is supposed that Spoon-billed Sandpiper are gathering into big group to prepare southward migration due to recent cold wave in Rudong.
The mud-flat locates in Xiao Yangkou, Rudong, and north of Yangtze River estuary, one of the important staging sites for migrating shorebirds along the East Asian-Australasian Flyway. A maximum of 24 SBS was counted during autumn 2010.
The Rudong Spoon-billed Sandpiper Survey Group of China Coastal Waterbird Census Team has started the water bird monitoring since 2010 and conservation effort are made to protect this area, which is under no protection.
Major threats to this area includes, pollution of chemistry developing zone cause the death of mudflat benthos; reclamation and the spread of spartina grass reduce the natural mud flat; illeagal hunting.
