Species
Taxon distribution as listed in assessment
This species is rare and uncommon in the UAE (Pedersen et al. 2017). The majority of occurrences are likely to be of migrant individuals on passage to and from the breeding grounds (Pedersen et al. 2017), but some individuals do over-winter in the UAE,;particularly during harsh winters in the northern part of the species's range in Eurasia (Richardson 1990, Pedersen et al. 2017). The species is found in the UAE between late October and April (Pedersen et al. 2017). It was first recorded in the country in December 1987 in Dubai City (Pedersen et al. 2017).

Habitat
Habitat details as listed in assessment
In the UAE, this species occurs in open plains with scattered trees and wooded foothills (Richardson 1990, Aspinall and Porter 2011). In winter, it generally prefers wet areas and is often found in marshes, but also in steppe, semi-desert, and wooded desert (Aspinall and Porter 2011). There is no information available on its diet in the UAE; elsewhere, it takes small to medium-sized mammals, birds, reptiles, amphibians and crustaceans (Meyburg and Kirwan 2019). Both adults and immatures are migratory. Birds migrating through the UAE breed in central Asia and winter in the Middle East, East Africa south to Tanzania and the Arabian peninsula. These birds make their southward migration between September and November, returning between February and May (Ferguson-Lees and Christie 2001). Birds are usually seen singly or in pairs, with small groups sometimes forming on migration or at sources of food or water (Richardson 1990, Ferguson-Lees and Christie 2001). In exceptional cases large groups of up to 200 have been known to form on autumn migration (Snow and Perrins 1998). Non-territorial birds often associate with other large eagles such as Greater Spotted Eagle Clanga clanga and White-tailed Sea-eagle Haliaeetus albicilla on wintering and temporary settlement areas.

Assessment rationale/justification
This species has an extremely small non-breeding population in the UAE, which qualifies it for listing as Critically Endangered. On a global scale, the species is listed as Vulnerable, as its small population is in rapid decline. Therefore, breeding populations outside of the country may not have a large rescue effect. The population trend within the UAE is not known. Given the global situation, the species is retained as Critically Endangered at the national level.

Threats listed in assessment
It is uncertain whether this species is impacted by any specific threats within UAE, although collisions with powerlines are possible. It does face a range of threats across its global range, all of which could impact individuals that visit UAE, and these are described below.Breeding sites are threatened primarily by intensive forestry in the mountains, and by the shortage of large indigenous trees in the lowlands (e.g. illegal tree cutting affected several pairs in Russia [Karyakin et al. 2009a] and Bulgaria).;The species is sensitive to human disturbance, which means its breeding range can be highly restricted by human presence and infrastructural development in Central Europe (and probably elsewhere in its range e.g. Karyakin;2011) (M. Horváth in litt. 2016). Infrastructural and settlement network was the primary cause for the absence of the species at more than 30% of its potential habitats at the Hungarian Plain (Horváth 2009).Other threats are loss and alteration of feeding habitats, shortages of small and medium-sized prey species (particularly ground-squirrels Spermophilus spp.), nest robbing and illegal trade, shooting, poisoning, electrocution by powerlines and collisions with vehicles. An average of c.450 Eastern Imperial Eagles were killed by powerlines during the 2009 breeding season in the Altai region -“ 25% of the total population of the region (Karyakin et al. 2009b). Habitat alterations associated with agricultural expansion threaten historical and potential breeding sites in former range countries. In Central Europe intentional predator poisoning became the first cause of mortality from 2006 onwards affecting more than 80 specimens in 10 years only in Hungary (Horváth et al. 2011, M. Horváth in litt. 2016). Hunting, poisoning, prey depletion and other mortality factors are also likely to pose threats along migration routes and in some wintering areas. Competition for nest sites with Greater Spotted Eagle Aquila clanga has been reported in the Altai region, Russia (Karyakin et al. 2009c).
