Species
Taxon distribution as listed in assessment
The majority of occurrences of this species within the UAE is likely to be of wintering birds and of migrant individuals on passage to and from the breeding grounds (Pedersen et al. 2017). The species is very common throughout the country between late November and early March (Richardson 1990, Pedersen et al. 2017). Individuals may stay during summer, but do not breed (Richardson 1990, Pedersen et al. 2017).

Habitat
Habitat details as listed in assessment
During the non-breeding season, this species is most common in coastal habitats and tidal inshore waters, showing a preference for inlets or estuaries with sandy or muddy beaches, and generally avoiding rocky or exposed coastlines (del Hoyo et al. 1996, Snow and Perrins 1998, Aspinall and Porter 2011). It may also occur inland during this season, frequenting ploughed fields, moist grasslands, urban parks, sewage treatment plants, refuse tips, reservoirs, ponds and ornamental waters, and roosts on sandy and gravel sites or on inland reservoirs (Richards 1990, Snow and Perrins 1998, Aspinall and Porter 2011). There is no information available about its diet in the UAE; elsewhere, it feeds predominantly of aquatic and terrestrial insects, earthworms and marine invertebrates, although it may also take fish, rodents and agricultural grain (Flint et al. 1984, del Hoyo et al. 1996). The species generally remains gregarious throughout the year and may roost in large flocks during the winter (Richards 1990). The species breeds between April and May in Eurasia, where it forms dense colonies of up to several thousand pairs (del Hoyo et al. 1996, Snow and Perrins 1998). ;

Assessment rationale/justification
This species has a large non-breeding population in the UAE, which is stable at very high numbers. Therefore, it is listed as Least Concern at the national level.

Conservation
Threats listed in assessment
The most relevant threat within UAE is the possibility of oil pollution (a threat also highlighted at the global level [Gorski et al. 1977]), but the severity of this threats towards this species is unknown.Individuals of this species that visit UAE are also threatened by a range of threats that operate outside of the country. The species is susceptible to avian influenza (Melville and Shortridge 2006) and avian botulism so may be threatened by future outbreaks of these diseases (Hubalek et al. 2005). It;has suffered local population declines in the past as a result of egg collecting (del Hoyo et al. 1996). In some areas of its breeding range the species may also suffer from reduced reproductive successes due to contamination with chemical pollutants (del Hoyo et al. 1996). None of these, however, are thought to be significant threats to the global population.

History
In 1996, populations will have been lower (no garbage dumps), but the species would still have been assessed as Least Concern.
