4. Shorebirds occuring in internationally important numbers at Yellow Sea sites (continued)
4.4 Species accounts (continued)
Subspecies None; entire global population confined to the EAAF.
Breeding: Yakutia, central and e. Amur Region, ne. China and Kamchatka.
Non-breeding: Coastal. Great majority in n., e. and se. Australia; few in South Korea, se. China and Taiwan.
Usage and importance of Yellow Sea
Occurrence: Intertidal areas. NM and SM Common on coasts of China and South Korea. NB Few s. from Yancheng NNR and on w. coast of South Korea. B Large numbers of immature birds (1718 max.) are present at Yancheng NNR in the northern summer. Numbers are probably underestimated, as this species is often spread thinly over upper tidal flats which are difficult to count effectively.
Movements: NM Arrive early March onwards after long non-stop flights from the non-breeding areas (Driscoll 2000), with main passage on e. and w. coasts of Yellow Sea during March and April. High numbers at Yalu Jiang NNR in early May could indicate that many birds relocate to n. Yellow Sea before leaving for breeding grounds. SM Return passage commences in early July, with peak passage during August and September. Birds from nw. and se. Australia occur in Yellow Sea on both NM and SM, but se. Australian birds seem to have a more easterly migration route on NM, including through Japan.
Significance of Yellow Sea: The Yellow Sea is extremely important for this near-threatened species as it supports about 80% of the estimated flyway population on NM. Fewer appear to occur during SM. Relatively few pass through Japan on either migration (e.g. 486 max.).
Key sites: 13 sites of international importance have been identified, 6 in China, 6 in South Korea and 1 in North Korea; 12 of the sites are important during NM and 7 during SM (see site location maps below). 6 sites are important during both NM and SM (Dong Sha, Shuangtaizihekou NNR, Ganghwa Do, Yeong Jong Do, Mangyeung Gang Hagu and Dongjin Gang Hagu). Yalu Jiang NNR supports almost 10% and Ganghwa Do >5% of the estimated flyway population during NM.
Status of key sites: 4 of the Chinese sites, the North Korean site and a small 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. Little information from North Korea.
CONSERVATION STATUS: Near threatened
EAAF POPULATION ESTIMATE: 38 000
Status: Passage migrant and uncommon non-breeding visitor
Estimated minimum numbers:
NM: South Korea: 6 500; China: 25 000.
SM: South Korea: 3 800.
