The National Red List Project

Please note, this National Red List website contains a subset of data whilst we transition to national focal point driven data uploads. We thank you for your patience with this and welcome national contributors to get in touch to update their national dataset. Terms of Use including citation guidance are found here.

The previous dataset is available via: https://archive.nationalredlist.org/. This site is no longer updated but can help with most enquiries whilst we focus on redevelopment.

Species
Taxon distribution as listed in assessment
This species is rare and uncommon in the UAE. It may have formerly bred in the north-eastern part of the country near Al Ain (Abu Dhabi Emirate) (Aspinall 1996, Pedersen et al. 2017). In the past decade, single individuals or small groups have been recorded in other parts of the country, like in Dubai Emirate (Dubai Desert Conservation Reserve, Dubai City, Nakhli, Tijarah desert, Saih Al Salam, Bab Al Shams desert), north-eastern Abu Dhabi Emirate (Al Shuwaib, Al Faqa), Sharjah Emirate (Wadi Al Helou, Dhaid to Al Madam road, Qarn Nazwa) and Ras al-Khaimah Emirate (Munay) (Pedersen et al. 2017).

Habitat
Habitat details as listed in assessment
This species inhabits open plains with rocky outcrops and wadis, as well as desert and semi-deserts with scattered trees (Jennings 2010, Aspinall and Porter 2011). Pairs range widely when foraging (P. Hall in litt. 2000), and soar for long periods in great heights (Richardson 1990). It feeds mostly on carrion, both on dead animals found on the plains and on road-kill (Jennings 2010). In Arabia, this species shows an aggressive behaviour towards congeners at carcasses, and dominates other vulture species (Jennings 2010). Moreover, the species also feeds near human habitations, such as on farmland, on rubbish dumps and in suburbs (Jennings 2010). Elsewhere, it is also known to hunt, probably taking a variety of small reptiles, fish, birds and mammals (McCulloch 2006a,b). Individuals do not breed until seven years old (Jennings 2010). There is no information available on the timing of the breeding season in the UAE, but it likely lasts from December to June/July (Jennings 2010). Nests are large structures of sturdy sticks, lined with soft material like goat and donkey hair and grasses, and may be used in consecutive years and are placed preferably in large, flat-topped acacia trees (Jennings 2010). Clutches likely contain only one egg (Shobrak 2004 per Jennings 2010). After fledging, juveniles may disperse up to 300 km from the nest (Jennings 2010).

Assessment rationale/justification
This species has a very small non-breeding population in the UAE, which qualifies it for listing as Critically Endangered. On a global scale, the species is listed as Endangered due to a rapid decline. Therefore, breeding populations outside of the country may not have a large rescue effect. Therefore, the species is retained as Critically Endangered at the national level.

Conservation
Threats listed in assessment
The species is known to face a very large range of threats that are having a severe impact on the global population. The population that visits the UAE, however, is probably naturally very small because it is at the very edge of its range in the country. It is probably naturally limited here by the lack of appropriate breeding sites, or possibly from the lack of large predators and their prey, and so the remains they feed on (Aspinall 1996). Instead, the principal food source in the region is potentially from dead domestic stock (Aspinall 1996), and this could potentially bring it into conflict with farmers. In the wider region it has been noted that the species may face persecution, and it could also be impacted by the poisoning of feral dogs/wolves (Symes et al. 2015). There is no evidence of any local susceptibility to diclofenac poisoning, which has impacted global vulture populations, but this should be monitored (Symes et al. 2015).
