4. Shorebirds occuring in internationally important numbers at Yellow Sea sites (continued)
4.4 Species accounts (continued)
Subspecies Worldwide 5 (alexandrinus, dealbatus, seebohmi, nivosus and occidentalis); Yellow Sea 1 (dealbatus) and, probably, alexandrinus.
Distribution of C. a. dealbatus and C. a. alexandrinus in the EAAF
Breeding: C. a. dealbatus, e. and se. China, s. Primorye, Sakhalin and s. Kurile Is., s. Japan and Ryukyu Is; C. a. alexandrinus, Torei L., s. Transbaikalia, Mongolia and ne. China.
Non-breeding: Mainly coastal, but also inland. C. a. dealbatus, e. and se. China, s. Japan, s. to The Philippines and Borneo. C. a. alexandrinus, w. Indonesia; also thought to occur in Taiwan (W.T. Liu in litt.).
Usage and importance of Yellow Sea
Occurrence: Intertidal areas and adjacent non-tidal wetlands. B Breeds widely around Yellow Sea coasts, but little data available. 1000 pairs at Shuangtaizihekou NNR (Y.X. Li in litt.), very common breeding bird at Yancheng NNR (H. Wang pers. comm.) and >500 pairs in South Korea (Yi & Kim in prep.). NM Widespread; very common in the Bo Hai and e. China, and common on w. coast of South Korea; few in n. China and sw. and s. coasts of South Korea. SM Similar to NM, except much large numbers in South Korea on w. and s. coasts. NB Common on e. coast of China; few elsewhere. Numbers are probably underestimated due to the dispersed distribution of the species.
Movements: NM Early migrant with numbers peaking in April, then declining significantly by late April. SM In South Korea, passage occurs during August to October.
Significance of Yellow Sea: The Yellow Sea is extremely important for this species as it supports >90% of the estimated flyway population during NM.
Key sites: 21 sites of international importance have been identified, 13 in South Korea and 8 in China; 11 of the sites are important during NM, 16 during SM and 4 during the NB season (see site location maps below). Breeds in internationally important numbers at Yancheng NNR and Shuangtaizihekou NNR (see map below for site locations). 6 sites are important on both NM and SM (Dong Sha, Yancheng NNR, Huang He NNR, Tianjin Municipality, Shi Jiu Tuo and Mangyeung Gang Hagu). Huang He NNR holds 25% and Chongming Dao PNR >5% of the estimated flyway population during NM, whilst Mangyeung Gang Hagu held >10% and Dongjin Gang Hagu, Shi Jiu Tuo and Yancheng NNR held >5% during SM.
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 2 most important sites during SM, the Dongjin and Mangyeung estuaries, are currently being reclaimed as part of the Saemangeum Reclamation Project.
Major gaps in knowledge: Insufficient information on general distribution of both subspecies and on the breeding distribution of dealbatus around Yellow Sea. Incomplete geographical and temporal coverage in China. No information from North Korea.
EAAF POPULATION ESTIMATE: 95 000
Status: Probably resident, breeding visitor, passage migrant and non-breeding visitor
Estimated minimum numbers:
NM: South Korea: 6 700; China: 83 000.
SM: South Korea: 38 000.
NB: South Korea: Few.
