Year Published: 2015

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 extremely 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.

Population [top]

Population:The global population is estimated to number c.1,100,000-2,000,000 individuals (Wetlands International 2006), while the population in Russia has been estimated at c.10,000-1 million breeding pairs and > c.1,000 individuals on migration (Brazil 2009).

Trend Justification:  The overall population trend is decreasing, although some populations have unknown trends (Wetlands International 2006). This species has undergone a small or statistically insignificant increase over the last 40 years in North America (data from Breeding Bird Survey and/or Christmas Bird Count: Butcher and Niven 2007) Note, however, that these surveys cover less than 50% of the species's range in North America.
Current Population Trend:Decreasing

Continuing decline in subpopulations:Unknown

Habitat and Ecology [top]

Habitat and Ecology:Behaviour This species is a full migrant that travels via marine routes and has been observed migrating 80-160 km offshore. Adult females depart from the breeding grounds in early-June, followed by the adult males and juveniles in late-July and August, most arriving in the non-breeding quarters by the end of November. The species departs Chilean and South African seas in March, and West African and south-west African seas in April, migrating along the Arctic coasts and reoccupying breeding grounds from late-May to early-June. It may also wait 2-3 weeks at the edge of sea ice in the High Arctic waiting for the land to thaw before nesting (Snow and Perrins 1998). Once in the breeding grounds the species breeds between June and July (from mid-June to mid-July in Iceland, and from early-June to early-July in Russia). The species is gregarious at all times of the year (Snow and Perrins 1998), and will even breed in loose groups where the habitat is favourable. Habitat Breeding This species breeds close to the coast on marshy tundra with small pools, on boggy meadows with moss and grass, in marshy river valleys, or on islets in fjords. Non-breeding Outside of the breeding season this species is pelagic and frequents upwelling zones in the tropics and subtropics where plankton occurs in high concentrations (e.g. over 50,000 organisms/litre). Diet Breeding During the breeding season the diet of this species consists chiefly of invertebrates, such as adult and larval insects (e.g. beetles, caddisflies, dipteran flies, bugs), molluscs, crustaceans, annelid worms, spiders, mites, jellyfish (Johnsgard 1981) and occasionally plant material (seeds) when animal matter is scarce. Non-breeding During this season the species feeds at sea on plankton, including amphipods less than 2 mm long, Hydrozoa and small fish from the water surface or just below. Breeding site The nest is a shallow cup or scrape on the ground in short vegetation (e.g. sedges or grasses) and is usually close to or surrounded by water (Johnsgard 1981, Snow and Perrins 1998).
