4.4 Species accounts (continued)

4.4.22 Curlew Sandpiper Calidris ferruginea

Subspecies None.

Distribution in the EAAF

Breeding: n. Taimyr to n. Chukotka.

Non-breeding: Mainly coastal. Bangladesh, Myanmar, se. Asia and Australia.

Usage and importance of Yellow Sea

Occurrence: Intertidal flats and adjacent non-tidal wetlands. NM and SM Uncommon, except for n. Bohai Wan during NM. Numbers counted are probably realistic estimates of birds present in surveyed areas.

Movements: NM Appears to migrate through inland China to Mongolia and s. Russia (Melville et al. in prep.; O. Goroshko in litt.); Bo Hai Wan is probably on the eastern extremity of the main migration path. Peak passage occurs in May. SM Uncommon; takes more westerly route than during NM (Minton 1998). Birds from nw., e. and se. Australia occur in Yellow Sea during NM.

Significance of Yellow Sea: Apart from n. Bohai Wan, the Yellow Sea is of minor importance for this species and it probably supports about 10% of the flyway breeding population during NM; very few birds occur during SM.

Key sites: 2 sites of international importance have been identified, both in China during NM (see site location map below). Tianjin Municipality supports >5% of the estimated flyway population during NM.

Status of key sites: Neither site is in a Protected Area.

Major gaps in knowledge: Insufficient geographical and temporal information from China, particularly from Bohai Wan.

Status: Passage migrant
Estimated minimum numbers:
NM: South Korea: Scarce; China: 18 000.
SM: South Korea: Scarce.
China: 2 (0)
