This species is strongly migratory, with different populations travelling on narrow or broad fronts depending on the location of their breeding and wintering grounds1. The species breeds between June and July2 after which it departs the breeding grounds from late-August or early-September1. It may forage singly or in flocks of one hundred or more individiuals, occurring in small groups of 3-7 individuals at stopover sites on the northward passage but in large flocks on the southward passage1.
<Breeding> It breeds on inland Arctic habitats including shrub tundra, montane tundra and stony well-drained uplands with mosses and lichens1.
<Non-breeding> The species occurs on the shores of lakes and rivers when on passage in the U.S.S.R.2, but outside of the breeding season in generally occupies coastal areas, foraging in coastal fields and prairies with short grass, ploughed fields1, coastal freshwater pools2, saltmarshes, beaches, open mud and sandflats1 and reefs2. It roosts on the same habitats used for foraging, as well as on exposed sandy beaches and exposed rocks1.
Its diet consists predominantly of insects, molluscs, worms, crustaceans and spiders, although berries are also important during the breeding season on the Arctic tundra1.
The nest is a shallow scrape positioned on a dry site amongst hummocks, lichen, Dryas spp. or moss1. The species shows a high degree of nest-site fidelity and will return to the same nest cup or to within 100 m of nest-site of previous year1.

LC
This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is very large, and hence does not approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
<Trend justification> The overall population trend is decreasing, although some populations have unknown trends (Wetlands International 2006). The population trend is decreasing in North America (based on BBS/CBC data: Butcher and Niven 2007).

The Asian Waterbird Census (AWC) was initiated in 1987 and runs in parallel with other waterbird censuses carried out in Africa, Europe, Central and West Asia and Latin America under the umbrella of the International Waterbird Census (IWC), which is organised by Wetlands International.
The AWC takes place annually, during the second and third weeks of January, and is carried out by volunteers interested in collecting information on waterbirds and wetlands as a basis for contributing to their conservation.
