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). The population trend appears to be stable, and hence the species does not 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:||The global population is estimated to number > c.1,000,000 individuals (Wetlands International 2015). The European population is estimated at 19,600-44,100 pairs, which equates to 39,300-88,200 mature individuals (BirdLife International 2015).|
Trend Justification: The overall population trend is stable, although some populations have unknown trends (Wetlands International 2015). In Europe the population size is estimated to be stable (BirdLife International 2015).
|Current Population Trend:||Stable|
|Habitat and Ecology:||Behaviour This species is fully migratory and crosses Europe on a broad front (del Hoyo et al. 1996). It breeds from May to early-September (del Hoyo et al. 1996) in well-dispersed solitary pairs (Johnsgard 1981, Snow and Perrins 1998), after which (between August and September) adults undergo a flightless moulting period close to the breeding grounds (del Hoyo et al. 1996). The autumn south-west migration occurs from mid-September to mid-November, with the species departing its wintering grounds again in March to mid-April (del Hoyo et al. 1996). Outside of the breeding season the species remains largely solitary, usually feeding singly or in groups of up to 5 individuals (del Hoyo et al. 1996). Most of its activities are carried out nocturnally or in the early morning and late evening (del Hoyo et al. 1996). Habitat Breeding The species breeds in the northern taiga and forest tundra zones on open grassy marshes and bogs with swampy ground (Johnsgard 1981, del Hoyo et al. 1996) on flood-plains (del Hoyo et al. 1996), in swampy coniferous forest, willow Salix spp. marshes or wet alder Alnus spp. woods (Johnsgard 1981). Non-breeding Outside of the breeding season it inhabits both fresh and brackish wetlands (del Hoyo et al. 1996) showing a preference for mosaics of moist and waterlogged mudflats with soft, silty mud and dense of tussocks vegetation (Hayman et al. 1986, del Hoyo et al. 1996). Suitable habitats include swamps, fens (Snow and Perrins 1998), grassy marshes (Johnsgard 1981), the margins of rivers and streams (del Hoyo et al. 1996, Snow and Perrins 1998), overgrown flood-lands, sewage farms (Snow and Perrins 1998), rice-fields (Johnsgard 1981), flooded arable fields, damp pastures and water meadows (Snow and Perrins 1998). Diet Its diet consists of adult and larval insects, annelid worms, small freshwater and terrestrial gastropods and the seeds and vegetative parts of aquatic and shoreline plants (Johnsgard 1981). Breeding site The nest is positioned on hummocks of sphagnum moss or grass tussocks on floating bogs just above the surrounding water (Johnsgard 1981), also on drier ground amongst bushes (del Hoyo et al. 1996) (e.g. dwarf birch Betula nana and heather) (Johnsgard 1981). Management information The annual success of reproduction is estimated every year by wing surveys in Denmark since the end of the 1970s, and in France since the mid-1990s. Hunting bags are estimated every year in Denmark (Clausager 2006).|
|Systems:||Terrestrial; Freshwater; Marine|
|Continuing decline in area, extent and/or quality of habitat:||Unknown|
|Generation Length (years):||5.4|
|Movement patterns:||Full Migrant|
|Congregatory:||Congregatory (and dispersive)|
|Major Threat(s):||The species is threatened by the loss and degradation of its wetland habitats through afforestation, peat extraction and drainage for agricultural intensification (del Hoyo et al. 1996). It also suffers from lead poisoning as a result of ingesting lead shot deposited on wetlands (Olivier 2006). Utilisation The species is hunted during the autumn migration (del Hoyo et al. 1996) (e.g. in Denmark) (Bregnballe et al. 2006).|
Conservation Actions Underway
The species is listed on Annex II (A) and III (B) of the EU Birds Directive. The following information refers to the species's European range only: The annual success of reproduction is estimated every year by wing surveys in Denmark since the end of the 1970s, and in France since the mid-1990s. Hunting bags are estimated every year in Denmark (Clausager 2006).
Conservation Actions Proposed
The following information refers to the species's European range only: Afforestation, peat extraction and drainage should be stopped. Hunting should be monitored and regulated to ensure it does not impact this species.
