4. Shorebirds occuring in internationally important numbers at Yellow Sea sites (continued)
4.4 Species accounts (continued)
Distribution in the EAAF
Breeding: Taimyr to n. Chukotka and e. Anadyr lowland, Wrangel Is. and nw. Alaska.
Non-breeding: Mainly coastal. Bangladesh, Myanmar, Indochina, s. and e. China, Japan, South Korea, se. Asia and Australia.
Usage and importance of Yellow Sea
Occurrence: Intertidal areas. NM Widespread and common, particularly in n. China and w. South Korea. SM Widespread, but less common than during NM. NB Common in the Mangyeung and Dongjin estuaries, smaller numbers elsewhere in South Korea and e. China. Numbers counted are probably realistic estimates of birds present in surveyed areas.
Movements: NM Peak numbers occur from mid-April to mid-May; se. Australian birds tend to have a more easterly migration route (probably mostly through Japan) than those from nw. Australia. SM Extended passage from August until October. Smaller numbers on SM indicate that the Australian and se. Asian populations probably fly non-stop across the Pacific to the non-breeding grounds.
Significance of Yellow Sea: The Yellow Sea is extremely important as it supports about 80% of the estimated flyway population during NM; many fewer birds occur during SM.
Key sites: 13 sites of international importance have been identified, 7 in China and 6 in South Korea; 12 of the sites are important during NM and 7 during SM (see site location maps below). 6 are important during both NM and SM (Shi Jiu Tuo, Yeong Jong Do, Namyang Man, Asan Man, Mangyeung Gang Hagu and Dongjin Gang Hagu). Huang He supports >10%, and Yalu Jiang NNR and Tianjin Municipality support >5%, of the estimated flyway population on NM.
Status of key sites: 4 of the Chinese sites and part of 1 of the South Korean sites (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. No information from North Korea.
EAAF POPULATION ESTIMATE: 125 000
Status: Passage migrant and non-breeding visitor
Estimated minimum numbers:
NM: South Korea: 18 000; China: 87 000.
SM: South Korea: 12 000.
NB: South Korea: 4 500.
