Geographic Range [top]
Range Description: This species breeds in northern and north-eastern Russia and sporadically in western and northern Alaska (U.S.A.). It winters from eastern India, Myanmar, southern China and Taiwan (China) to the Philippines, Indonesia, the Solomon Islands, Australia and New Zealand (Van Gils et al. 2013).

Population [top]
Population: The global population is estimated to number c.315,000 individuals (Wetlands International 2015) of which c. 270,000 reach Australia during the non-breeding season.
Trend Justification: The overall population trend is thought to be declining, based on monitoring data from Australia and New Zealand which reported a population decline of 29% over three generations (Studds et al. in prep). Further research is needed to ascertain whether this is entirely due to a genuine global decline or whether it can partly be accounted for by a shift in the wintering range.
Current Population Trend: Decreasing
Additional data:
? Continuing decline of mature individuals: Yes
? Extreme fluctuations: No ? Population severely fragmented: No
? Continuing decline in subpopulations: Unknown
? Extreme fluctuations in subpopulations: No ? All individuals in one subpopulation: No
Habitat and Ecology [top]
Habitat and Ecology: During the breeding season the species uses low altitude montane tundra in the subalpine belt. In the non-breeding season it mainly uses coastal and intertidal mudflats, sheltered inlets, bays and lagoons but it also uses freshwater, brackish and saltwater wetlands and occasionally sandy beaches and rocky shorelines (Van Gils et al. 2013).
Systems: Terrestrial; Marine
Continuing decline in area, extent and/or quality of habitat: Unknown
Generation Length (years): 7.5
Movement patterns: Full Migrant
Congregatory: Congregatory (and dispersive)
Threats [top]
Major Threat(s): The species is restricted to the East Asian-Australasian Flyway and habitat loss at critical stopover sites in the Yellow Sea is suspected to be the most important threat to this species. Habitat loss within the Yellow Sea region is thought to be driving waterbird population declines (Amano et al. 2010, Yang et al. 2011). Up to 65% of intertidal habitat in the Yellow Sea has been lost over the past 50 years, and habitat is currently disappearing at a rate of >1% annually since the 1980s owing to reclamation for agriculture, aquaculture, and other development (Murray et al. 2014). Hundreds of birds died as a result of pesticide applications in Western Australia (Van Gils et al. 2013).
Conservation Actions [top]
Conservation Actions: Conservation and Research Actions Underway
The species is classified as Near Threatened in Australia.
Conservation and Research Actions Proposed
Protect key stopover sites in the Yellow Sea. Continue to monitor the population. Implement research to ascertain whether the population decline reported for Australia and New Zealand represents a genuine decline or a shift in the speciess wintering range.
