Distribution in the EAAF
Breeding: Yakutia, w. and central Chukotka, Kamchatka Magadan and L. Baikal region.
Non-breeding: Coastal and inland. Bangladesh, Myanmar, Thailand, Indochina, s. China, se. Asia, w. Melanesia, s. New Guinea and Australia.
Usage and importance of Yellow Sea
Occurrence: Intertidal areas and adjacent non-tidal wetlands. NM and SM Widespread and common; particularly numerous in Yancheng NNR. NB Common south from Yancheng. Numbers are probably underestimated, as this species often occurs on non-tidal wetlands which were generally less well surveyed than intertidal areas.
Movements: Probably mainly a broad-front migrant using a variety of inland and coastal wetlands.
Significance of Yellow Sea: The Yellow Sea is important for this species as it supports about 25% of the estimated flyway population during NM. Numbers may be higher during SM.
Key sites: 11 sites of international importance have been identified, 6 in South Korea and 5 in China; 4 of the sites are important during NM, 8 during SM and 1 in the NB season (see site location maps below). Yancheng NNR is important during both NM and SM.
Status of key sites: 3 of the Chinese sites and a small part of 1 of the South Korean sites (Dongjin Gang Hagu) are in Protected Areas. Dongjin Gang Hagu is currently being reclaimed as part of the Saemangeum Reclamation Project.
Major gaps in knowledge: Incomplete geographical and temporal coverage in China, especially of coastal non-tidal wetlands. No information from North Korea.
