Assessment rationale/justification
This species has a small breeding and a very small non-breeding population. Both the breeding population and the non-breeding populations are assumed to be increasing within the UAE. The breeding population size is low enough, though, that it triggers listing as Vulnerable under Criterion D1. Based on the regional criteria, however, the breeding population warrants a regional adjustment of one category to Near Threatened due to the likelihood of a rescue effect.The non-breeding population is under a greater risk of extinction, qualifying as Endangered, but undergoing an adjustment down to Vulnerable based on global status (LC). However, the national status is based on its breeding population, which takes precedence. Therefore, overall the species is listed as Near Threatened.

Taxon distribution as listed in assessment
This species breeds along the southwestern and west coast of the UAE, as well as in the mountains in the northern and north-eastern part of the country (Jennings 2010, Pedersen et al. 2017). The breeding population is temporarily supplemented by migrant individuals on passage to and from the breeding grounds (Pedersen et al. 2017). Some individuals stay in the country during the non-breeding season (Pedersen et al. 2017).

Habitat
Habitat details as listed in assessment
During the breeding season, this species inhabits preferably freshwater sites like gravelly river islands, sandy shores of lakes, brackish and freshwater ponds as well as sewage treatment plants, and is also found at pools in remote deserts and along streams in the mountains (Richardson 1990, Jennings 2010, Aspinall and Porter 2011). The preferred habitat of individuals overwintering in the UAE is not well known; but it may frequent more coastal areas like mudflats (Aspinall and Porter 2011). Migrants mainly occur in small flocks between February and April on their journey to the breeding grounds and between September and October on passage to the wintering grounds; they tend to stay further inland at temporary desert rain pools, while avoiding mudflats along the coast (Richardson 1990, Jennings 2010). Its diet consists mainly of terrestrial and aquatic invertebrates, which it takes from the water surface or wet ground, often near fish drying places or livestock enclosures (Jennings 2010). The breeding season lasts from March to July (Jennings 2010). The species is territorial and nests in open areas with patches of sand or shingle near streams and lagoons of freshwater, brackish water or irrigated lands (Jennings 2010). The nest consists of a shallow, unlined depression in gravel or bare ground, in which three to four eggs are laid (Jennings 2010).
Threats and conservation measures listed
Threats listed in assessment
The main potential threat to this species within UAE is the infilling of its wetland habitat (Aspinall 1996).
History
The breeding population is thought to have been 150-300 mature individuals in 1996, qualifying as Endangered, but adjusted down to Vulnerable based on rescue effect. The population has increased since then and it is now listed as Near Threatened.
