Assessment rationale/justification
This species potentially has a very small resident population within the UAE. It is difficult to assess the population trend, because the population can fluctuate considerably between years. But at the very least the species qualifies for listing as Endangered under Criterion D.

Taxon distribution as listed in assessment
This species is a common resident particularly in the northern part of the country and along the coast, as well as on islands close to the mainland (Jennings 2010, Pedersen et al. 2017). In winter, the species undertakes seasonal movements (Jennings 2010).

Habitat
Habitat details as listed in assessment
This species occurs in lowland plains, preferably in sandy, but also in gravelly or bare country and scrubland (Jennings 2010, Aspinall and Porter 2011). It also frequents coastal dunes, beaches and inshore islands (Aspinall and Porter 2011). Even though it inhabits mostly arid zones, it needs daily access to water, for which it may fly more than 30 km one way (Jennings 2010). There is no information available on its diet in the UAE; elsewhere in Arabia and Africa it takes seeds, spilt grain, plant shoots and insects (Jennings 2010). The species is undergoing seasonal feeding movements, which are most likely triggered by food shortage in the area (Jennings 2010). The species breeds opportunistically when conditions are favourable and rainfall has been sufficient. Consequently, it may breed year-round, though most breeding activity has been recorded in April and May (Jennings 2010). The nest is scraped in the sand or gravel, often unshaded and in bare country, although there is usually some vegetation nearby (Jennings 2010). Clutches contain two to three eggs. Both adults assist in incubating the eggs and raising the young, which often stick to their parents until fully grown (Jennings 2010).
Threats and conservation measures listed
Threats listed in assessment
In UAE this species is under threat from anthropogenic disturbance and loss of habitat due to land-use changes (Aspinall 1996, Symes et al. 2015). Feral dogs may also be a potential threat.
History
It is assessed that in 1996, the national Red List status of this species would have been the same as in this assessment.
