Taxonomic Notes
Chlamydotis undulata and C. macqueenii (del Hoyo and Collar 2014) were previously lumped as C. undulata following Sibley and Monroe (1990, 1993).
Taxon distribution as listed in assessment
Formerly a widespread breeding and wintering bird, this species is now uncommon to rare during winter and on passage in the UAE (Jennings 2010, Pedersen et al. 2017). The migratory population winters in the country between October and March before returning to the breeding grounds in Iran, Afghanistan, Uzbekistan and western China (Jennings 2010, Pedersen et al. 2017). Since 2004, the species has been reintroduced in Abu Dhabi Emirate (Pedersen et al. 2017). Between 2004 and 2013, over 4,500 individuals have been released, many of which were un-ringed (Pedersen et al. 2017). The reintroduced population has since bred successfully, though it is not clear whether it interbreeds with the native population (Jennings 2010, Pedersen et al. 2017).

Habitat details as listed in assessment
As this species is very elusive and shy of humans, it is not well studied and its biology in the UAE is not well known. It occurs on open sandy or gravelly plains including undulating sand dunes, sparsely vegetated semi-desert, desert scrubland and occasionally cropfields and irrigated areas (Richardson 1990, Jennings 2010, Aspinall and Porter 2011). It favours scattered shrubby vegetation, typically comprising xerophytic or halophytic plants (Collar 1996). It feeds nocturnally and mainly on invertebrates, but also on plant matter (Jennings 2010). When foraging, it ranges over vast areas and may move up to 60 km per day (Jennings 2010). The species is adapted to arid conditions and can take its liquids exclusively from food (Jennings 2010). In general, at the onset of the breeding season, males attract their mates with an extravagant courtship display, which they perform at the same site each year. The display begins with a period of strutting and culminates with the male retracting his head within an ornamental shield of erected neck feathers and then running at speed in either a straight or curved line. The display is often accompanied by a series of subsonic booming calls (Gaucher et al. 1996). The timing of breeding is not well known however and seems to vary by location; records from Oman suggest that eggs are laid between January and April and between August and November (Jennings 2010). No nest has been described from the UAE; in general, females create a shallow scrape in the ground in which they typically lay 3-4 eggs, and occasionally up to six eggs in long-distance migrants (Collar 1996, Combreau et al. 2002). The incubation period is typically 24 days, whilst fledging takes around 35 days. Males play no part in rearing the young, and a brood may contain young sired by several different individuals (Lesobre et al. 2010).

Assessment rationale/justification
This species is thought to have historically gone extinct as a breeding species in the UAE. However, thanks to a reintroduction programme the species is breeding again in the country. While many birds have been released, and there are now 2<sup>nd</sup> generation individuals in the wild, the number of birds that meet the conditions for inclusion in a Red List assessment is still likely to be tiny. Therefore, the breeding population, which takes precedence here, is given a status of Critically Endangered.Regarding the non-breeding population, there is a high degree of uncertainty regarding the population figures and trend for this visiting population, although the global and regional trend is for rapid declines. We cannot be confident, though, that this is the case for the UAE. The wintering population is roughly suspected to be c.100 individuals, which potentially could roughly equate to c.67 mature individuals, if we assume that the 100 individuals includes both mature and immature birds. With an uncertain trend, this population would be considered as Endangered under criterion D. However, if further information were to show this population is declining it would warrant listing as Critically Endangered.

Conservation
Threats listed in assessment
All global threats are likely to be relevant to a discussion of the species's current status within UAE, as they may have historically contributed to its disappearance as a natural breeding species within the country, and may continue to impact individuals that visit the country naturally during the non-breeding season. The principal global threat outside of the UAE is from hunting, largely but not exclusively on the species's wintering grounds (Judas et al. 2009). Large numbers are also trapped, mainly in Pakistan and Iran, and shipped to Arabia for use in the training of falcons (Combreau 2007). In 2014 an illegal shipment of 240 birds was intercepted en route from Pakistan to Bahrain (Shafaeipour et al. 2015). In parts of the region, fast-paced development related to the growth of the petroleum industry has reduced the availability of undisturbed habitats and further exacerbated the species's decline. Oil exploration, road building, oil and water pipelines, mining and quarrying activities, powerlines and the general disturbance caused by four-wheel drive vehicles have all been identified as significant auxiliary threats. Powerlines in particular may be a significant threat (Aspinall 1996, M. Koshkin in litt. 2016). Preliminary data from Uzbekistan suggests that powerlines may contribute to species mortality (Burnside et al. 2015).Livestock grazing is reported to have a negative impact on the species, both indirectly, by degrading the desert vegetation on which birds rely for food and concealment, and directly, through the trampling of nests and disturbance of nesting females (Lavee 1988). Recent research on the effects of pastoralism on this species in the Kyzylkum Desert in Uzbekistan, however, has found that low intensity livestock grazing may not widely degrade rangelands at a landscape scale (Koshkin et al. 2014) and has no effect on male abundance and female nesting success (Koshkin et al. 2016a,b). In Iran, loss of habitat to croplands, mainly through the planting of pistachio, has been judged to be a significant threat (Mansoori 2006); however, it has also been found that the species exploits other crops such as alfalfa and salad rocket (Aghanajafizadeh et al. 2010). In Saudi Arabia, eggs and nests are predated by a range of mammalian predators (M. Zafar-ul Islam in litt. 2016).Within the UAE itself, the main threats that have been identified come from habitat loss, although conversion of its habitat to agricultural land could actually benefit the species as they may use alfalfa fields for feeding. The tiny breeding population size itself creates the risk for genetic drift. There are also risks that need to be carefully monitored surrounding to what extent released individuals may be adapted to human care - for instance increasing the risk of collisions with vehicles if released individuals approach too closely - and there is a risk of disease spreading through the population when individuals congregate in high densities in certain areas, such as feeding stations.
