4.4 Species accounts (continued)
Distribution in the EAAF
Breeding: Yakutia, Chukotka and Koryak Highlands.
Non-breeding: Coastal. Bangladesh, Myanmar, Thailand, Indochina, se. Asia, New Guinea and Australia.
Usage and importance of Yellow Sea
Occurrence: Intertidal areas. NM and SM Widespread, but more numerous in South Korea. In China most common in the Bo Hai. Higher numbers during SM. Numbers are probably significantly underestimated, as this species often roosts in non-tidal ponds and along river banks both of which are difficult to count effectively.
Movements: NM Peak numbers in South Korea in mid-May. SM Peak numbers in South Korea in August. Insufficient data from China. Birds from nw. and n. Australia occur in the Yellow Sea.
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 are higher on SM.
Key sites: 14 sites of international importance have been identified, 11 in South Korea and 3 in China; 9 of the sites are important during NM and 13 during SM (see site location maps below). 8 sites are important during both NM and SM (Huang He NNR, Ganghwa Do, Yeong Jong Do, Namyang Man, Asan Man, Geum Gang Hagu, Dongjin Gang Hagu and Suncheon Man).
Status of key sites: 2 of the Chinese sites and a small part of 1 South Korean site (Dongjin Gang Hagu) are within Protected Areas. The Dongjin and Mangyeung estuaries are 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 and river banks. No information from North Korea.
