Distribution in the EAAF
Breeding range: w. and e of L. Baikal, central Yakutia and ne. China.
Non-breeding: Coastal and inland. Bangladesh, Myanmar, Thailand, Indochina, s. and e. China, Japan, se. Asia, New Guinea and Australia.
Usage and importance of Yellow Sea
Occurrence: Intertidal areas and adjacent non-tidal wetlands. NM and SM Common in China from Chang Jiang Estuary to n. Liaodong Wan, with large numbers in Yancheng NNR and around Bohai Wan; none recorded at Yalu Jiang NNR and scarce in South Korea. NB Present in good numbers at Yancheng NNR. Numbers are probably underestimated, as this species often occurs on non-tidal wetlands which were generally less well surveyed than intertidal areas.
Movements: NM Limited information indicates that main arrivals occur in late April, with large numbers still present in mid-May. SM No information. Probably migrates on a broad front through inland China and along the Chinese coast.
Significance of Yellow Sea: The Yellow Sea is important for this species during NM when it supports about 40% of the estimated flyway population. Also common on SM.
Key sites: 5 sites of international importance have been identified, all in China; 3 of the sites are important during NM and 4 during SM (see site location maps below), with Yancheng NNR and Huang He NNR being important during both NM and SM. Yancheng NNR supports 10% of the estimated flyway population during NM and >5% during SM.
Status of key sites: 2 of the 5 sites are in Protected Areas.
Major gaps in knowledge: Incomplete geographical and temporal information from China, particularly from Bohai Wan and non-tidal areas.
