Assessment rationale/justification
This species has a very small breeding population in the UAE, which might qualify it for listing as Critically Endangered. However, the population is increasing, and the potential for immigration from outside the UAE remains very high. Therefore, the species's status has undergone a regional adjustment; down one category and is thus listed as Endangered at the national level, as the evidence for increase is not yet in place.

Taxon distribution as listed in assessment
From 2002 on, this species occurred as a vagrant, but regularly, at Al Warsan Lakes near Dubai City, where up to eight pairs have been breeding annually since 2004. In 2013 and 2016, breeding was confirmed in the Al Wathba Wetland Reserve (Pedersen et al. 2017). Between 1984 and 2016, the species has been recorded at multiple locations in Dubai City (Jebel Ali Hotel, Al Warsan Lakes, Zabeel Ponds, Emirates Golf Club), Sharjah City (Ramtha Rubbish Tip), as well as in Ruwais Housing Complex and Ain Al Fayda in Abu Dhabi Emirate (Pedersen et al. 2017). Moreover, several birds have been released in the last decades: In 1997, 25 individuals were released in Abu Al Abyad Island; in 2004, 20 individuals were released near Mushrif National Park in Dubai, which were not found again in 2013; in 2012, several individuals were released near Al Ajban in Dubai Emirate (Pedersen et al. 2017). One individual of uncertain origin was recorded in 2013 near Al Madam in Sharjah Emirate (Pedersen et al. 2017).

Habitat details as listed in assessment
This species occurs in brackish and freshwater habitats with dense vegetation cover, like swamps, reed beds and lake borders, but it may also be found in small temporary wetlands (Jennings 2010, Aspinall and Porter 2011). The species is mainly crepuscular and forages in the early-morning and late-evening (del Hoyo et al. 1996). There is no information available about its diet in the UAE; elsewhere the diet consists predominantly of plant matter including shoots, leaves, roots, stems, flowers and seeds (del Hoyo et al. 1996, Taylor and van Perlo 1998). It also takes animal matter including molluscs, leeches, small crustaceans, adult and larval insects, earthworms, spiders, fish and fish eggs, frogs and frog spawn, lizards, water snakes Natrix maura, adult birds, bird eggs and nestlings, small rodents and carrion (del Hoyo et al. 1996, Taylor and van Perlo 1998). Its breeding biology is not well studied; the timing of breeding is unknown and seems to be erratic, as chicks have been recorded in Dubai in October and April (Jennings 2010). No nest has been described from the UAE. Elsewhere, it breeds in solitary territorial pairs or in small communal groups containing several breeding males, breeding females and non-breeding helpers and the nest it is a shallow cup in a large substantial structure of vegetation built on a platform of vegetation floating on or standing in shallow water 30-120 cm deep and concealed in thick vegetation (del Hoyo et al. 1996, Taylor and van Perlo 1998).
Threats and conservation measures listed
Threats listed in assessment
The main threat to this species within UAE is likely to be from land-use changes. Globally the use of pesticides has been noted as a possible threat too, although this is unlikely to impact individuals in the UAE. The species is also susceptible to avian influenza (Melville and Shortridge 2006, Gaidet;et al.;2007) and avian botulism, so may be threatened by future outbreaks of these diseases (Galvin;et al.;1985).
History
The species was not breeding in the UAE in 1996; the first breeding record was in 2004. Therefore, it would not have been assessed in 1996.
