4.4 Species accounts (continued)
Subspecies Worldwide and EAAF 3 (curonicus, jerdoni and dubius); Yellow Sea 1 (curonicus).
Distribution of C. d. curonicus in EAAF
Breeding: Russian Far East, Mongolia, w., central and e. China, Korean Pen. and Japan.
Non-breeding: Coastal and inland. e. China and se. Asia.
Usage and importance of Yellow Sea
Occurrence: Intertidal areas, adjacent non-tidal wetlands and river banks. NM and SM Widespread in China from Chang Jiang Estuary to Bohai Wan. Few in South Korea. Numbers are probably underestimated, as this species often occurs on non-tidal wetlands which were generally less well surveyed than intertidal areas.
Movements: No information.
Significance of Yellow Sea: There is insufficient information to allow an estimate to be made of numbers occurring in China.
Key sites: 4 sites of international importance have been identified, all in China; all 4 sites are important during NM and 2 during SM (see site location maps below). Yancheng NNR and Tianjin Municipality are important during both NM and SM. Yancheng NNR holds >10% of the estimated flyway population during SM.
Status of key sites: 2 of the sites are in Protected Areas.
Major gaps in knowledge: Improved geographical and temporal information from China, especially in coastal non-tidal wetlands.
EAAF POPULATION ESTIMATE 25 000
Status: Passage migrant
Estimated minimum numbers:
No estimates; few in South Korea.
