4.4 Species accounts (continued)

4.4.20 Sharp-tailed Sandpiper Calidris acuminata

Subspecies None; entire global population confined to the EAAF.

Distribution

Breeding: n. Yakutia and nw. Chukotka.

Non-breeding: Inland and coastal. s. New Guinea and Australia; mainly in se. Australia.

Usage and importance of Yellow Sea

Occurrence: Intertidal areas and adjacent non-tidal wetlands. NM Widespread and generally common, but nowhere present in large concentrations. SM Similar to NM on Chinese coast, but scarce in South Korea. Numbers are probably underestimated due to the dispersed distribution of the species.

Movements: NM Main passage through South Korea during May. SM Insufficient information. Birds from se., e. and n. Australia pass through Yellow Sea. Probably a broad-front migrant with many adult birds passing through inland China on both NM and SM; most juveniles migrate s. along the Pacific coast (Mlodinow 2001).

Significance of Yellow Sea: The Yellow Sea appears to be relatively unimportant for this species, supporting about 10% of the estimated flyway population during NM. Numbers may be lower during SM.

Key sites: 2 sites of international importance have been identified, both in China; both sites are important during NM and 1 during SM (see site location maps below). Yancheng NNR is important during both NM and SM.

Status of key sites: 1 site is in a Protected Area.

Major gaps in knowledge: Incomplete geographical and temporal coverage in China, especially of coastal non-tidal wetlands. No information from North Korea.

EAAF POPULATION ESTIMATE: 160 000
YELLOW SEA
Status: Passage migrant
Estimated minimum numbers:
NM: South Korea: 2 600; China: 15 000.
SM: South Korea: Scarce.
