4.4 Species accounts (continued)

4.4.19 Red-necked Stint Calidris ruficollis

Subspecies None; entire global population confined to the EAAF.

Distribution

Breeding: Taimyr to Chukotka and Koryak Highlands.

Non-breeding: Mostly coastal. Mainly in Australia, but also Thailand, e. and s. China, se. Asia and New Guinea.

Usage and importance of Yellow Sea

Occurrence: Intertidal areas. NM and SM Widespread and generally common, but nowhere present in very large concentrations. NB Small number in Chang Jiang Estuary. Numbers counted are probably realistic estimates of birds present in surveyed areas.

Movements: NM and SM In South Korea main passage is in May and in September. Insufficient information for China. Birds from all areas of Australia migrate through Yellow Sea. This species appears to be a broad-front migrant with many birds probably migrating across inland China to Mongolia and s. Russia (Goroshko 1999).

Significance of Yellow Sea: The Yellow Sea is of importance for this species as it supports about 30% of the estimated flyway population during NM. It may be less common during SM.

Key sites: 5 sites of international importance have been identified, 3 in South Korea and 2 in China; all 5 sites are important during NM and 2 during SM (see site location maps below). Yancheng NNR and Mangyeung Gang Hagu are important during both NM and SM.

Status of key sites: 1 Chinese site 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. No information from North Korea.
