Assessment rationale/justification
This species has a restricted, stable non-breeding population in the UAE, which qualifies it for listing as Vulnerable. On a global scale, the species is listed as Near Threatened due to a rapid decline in recent years. Therefore, breeding populations outside of the country may not have a large rescue effect. Therefore, the species is precautionarily retained as Vulnerable at the national level.

Taxon distribution as listed in assessment
The majority of occurrences of this species within the UAE are likely to be of wintering birds and migrant individuals on passage to and from the breeding grounds (Pedersen et al. 2017). The species is very common between July and April, with only a few non-breeding individuals staying over summer in the country (Richardson 1990, Pedersen et al. 2017).

Habitat
Habitat details as listed in assessment
This species occurs along the coast, where it frequents tidal mudflats, sandy and rocky shores and coral reefs (Richardson 1990, Aspinall and Porter 2011). It also utilises wet grassland, open parkland and arable fields during migration (Richardson 1990, del Hoyo et al. 1996, Aspinall and Porter 2011). There is no information available about its diet in the UAE; elsewhere it mainly feeds on annelid worms and terrestrial insects, but it will also take crustaceans, molluscs, polychaete worms, spiders, berries and seeds, as well as occasionally small fish, amphibians, lizards, young birds and small rodents (Johnsgard 1981, del Hoyo et al. 1996). During the winter, the species usually forages singly or in small groups, occasionally aggregating into flocks of several thousand individuals, especially at roosting sites (del Hoyo et al. 1996, Snow and Perrins 1998). The species is migratory and breeds from April to August throughout Eurasia (Hayman et al. 1986, del Hoyo et al. 1996). It leaves its wintering grounds in the UAE by April, although non-breeders may remain in the wintering areas all year round (Richardson 1990, del Hoyo et al. 1996, Pedersen et al. 2017).
Threats and conservation measures listed
Threats listed in assessment
Changes in coastal land-use and the possibility of oil pollution could affect this species in UAE, but the severity of these threats towards this species is unknown.Individuals of this species that over-winter in UAE are also impacted by a range of threats outside of the country (e.g. on their breeding ground). The species is threatened by the loss and fragmentation of moorland habitats as a result of afforestation (del Hoyo et al. 1996, Johnsgard 1981) and of marginal grassland habitats as a result of agricultural intensification and improvement (Johnsgard 1981,Baines 1988,;del Hoyo;et al.;1996) (e.g. drainage, inorganic fertilisation and reseeding) (Baines 1988). The species also suffers from high egg and chick mortalities due to agricultural practices (e.g. Tuellinghoff and Bergmann 1993, Grant 1997, Fisher and Walker 2015), human disturbance (Boschert and Rupp 1993) and higher predation rates if nesting on improved grasslands or in fragmented landscapes (del Hoyo et al. 1996, Valkama and Korpimäki 1999, Douglas et al. 2014). Conversely, some populations have declined following abandonment of farmland and subsequent increases in the height of vegetation (Broyer and Roche 1991), rendering large areas unsuitable for nesting. Climate change is projected to have a large negative impact on this species during the breeding season (Huntley et al. 2007, Renwick et al.;2012). Expansion of renewable energy projects including wind farms can also have an impact, although more studies are required (Pearce-Higgins et al. 2009). The species has also suffered population declines as a result of hunting (Johnsgard 1981), and is susceptible to avian influenza so may be threatened by future outbreaks of the virus (Melville and Shortridge 2006).
History
Populations may have been smaller in 1996, but not below the threshold for EN. Therefore, this species would have been considered Vulnerable in 1996.
