This species has been uplisted to Critically Endangered due to severe declines in parts of its range. Overall it is suspected to have undergone a very rapid decline owing to habitat loss and conversion to agro-pastoral systems, declines in wild ungulate populations, hunting for trade, persecution, collision and poisoning.

Gyps rueppelli (del Hoyo and Collar 2014) was previously listed as G. rueppellii.
85-97 cm. Medium-sized vulture. Overall dark brown plumage with extensive pale creamy edging to body feathers. Dark flight feathers. Has a white ruff, dark neck and pale head. Distal half of the bill is pale. Juveniles have an all dark bill and paler body plumage. The centres to their body feathers are altogether less dark. Similar spp. Within its range this species could be confused with G. fulvus or G. africanus. However, both of those species are less mottled and have uniform light brown body plumage. G. africanus has an all dark bill.
Mundy et al. (1992) estimated a population perhaps of the order of 11,000 pairs, comprising 3,000 pairs in Tanzania, 2,000 in Kenya where 'up to thousands' concentrated at favoured sites, 2,000 in Ethiopia where it was said to be 'common to locally abundant', 2,000 in Sudan where was the 'most common vulture in the North', and 2,000 for West Africa. This could indicate a population of 22,000 mature individuals and perhaps c.30,000 individuals at the start of the 1990s. Subsequent extremely rapid population declines mean that the population is now likely to be much lower.
New data suggests this species has experienced a very rapid population decline of 97% (range: 94-99%) over three generations (56 years) (Ogada et al. 2015). Extremely rapid declines have been reported in West Africa (Thiollay 2006; although in Gambia it appears to be stable): during vehicle-based transect surveys in the Sahel zone of Mali and Niger in 2006 the species was not recorded, despite being common during equivalent surveys in the early 1970s. Significant declines appear to have occurred elsewhere in the range, including Sudan (Nikolaus 2006), Uganda (D. Pomeroy in litt. 2006), Kenya (M. Virani in litt. 2006, Virani et al. 2011) and Tanzania (J. Wolstencroft in litt. 2006), but it may be stable in Ethiopia (Nikolaus 2006). Virani et al. (2011) documented an apparent decline of c. 52% over c. 15 years in the numbers of Gyps vultures present during the ungulate migration season, while in central Kenya an apparent decline of 69% was noted in the numbers of Gyps vultures between 2001 and 2003 (Ogada and Keesing 2010). Declines observed in the Masai Mara study may be representative of declines in Gyps populations ranging across East Africa from Southern Ethiopia to Southern Tanzania (C. Kendall in litt. 2012).
It frequents open areas of Acacia woodland, grassland and montane regions, and it is gregarious, congregating at carrion, soaring together in flocks and breeding mainly in colonies on cliff faces and escarpments at a broad range of elevations. It locates food entirely by sight.
The species faces similar threats to other African vultures, being susceptible to habitat conversion to agro-pastoral systems, loss of wild ungulates leading to a reduced availability of carrion, hunting for trade, persecution and poisoning (Ogada et al. 2015). In East Africa, the primary issue is poisoning (particularly from the highly toxic pesticide carbofuran), which occurs primarily outside protected areas; the large range sizes of this and G. africanus puts them both at significant risk as it means they inevitably spend considerable time outside protected areas (Ogada and Keesing 2010, Otieno et al. 2010, Kendall and Virani in press). In addition, the ungulate wildlife populations on which this species relies have declined precipitously throughout East Africa, even in protected areas (Western et al. 2009).
In 2007, diclofenac, a non-steroidal anti-inflammatory drug often used for livestock, and which is fatal to Gyps spp. when ingested at livestock carcasses, was found to be on sale at a veterinary practice in Tanzania (BirdLife International 2007). In addition, it was reported that in Tanzania, a Brazilian manufacturer has been aggressively marketing the drug for veterinary purposes (C. Bowden in litt. 2007) and exporting it to 15 African countries (BirdLife International 2007). The West African population has been heavily exploited for trade, with birds commonly sold in fetish markets (Rondeau and Thiollay 2004, Nikolaus 2006, Buij et al. 2015). It is one of the most commonly traded vultures in West and Central African markets, with numbers traded (1,128-1,692 individuals over a six year period in West Africa) probably representing a significant proportion of the regional population (Buij et al. 2015). The Dogon of central Mali climb the Hombori cliffs to take eggs and chicks of this species (Rondeau and Thiollay 2004). The decline and possible extirpation in Nigeria appears to be entirely attributable to the trade in vulture parts for traditional juju practices (P. Hall in litt. 2011). It is apparently also captured for international trade. In 2005, 30 birds were reportedly confiscated by the Italian authorities (F. Genero in litt. 2005). Disturbance, especially from climbers, is a particular problem for this species. In Mali, the Hombori and Dyounde massifs are dotted with at least 47 climbing routes, on which expeditions take place every year, mainly during the species's breeding season. However, the impact of these activities is not known (Rondeau and Thiollay 2004).
Conservation and Research Actions Underway
CITES Appendix II. This species occurs in a number of protected areas across Africa. It was included in a CITES Significant Trade Review. In 2007, a survey began to establish the extent of diclofenac use for veterinary purposes in Tanzania (BirdLife International 2007), and in 2008 an awareness-raising campaign at a conference of the World Organisation for Animal Health in Senegal led to a resolution being adopted unanimously by more than 160 delegates to "request Members to consider their national situation with the aim to seek measures to find solutions to the problems caused by the administration of diclofenac in livestock" (Woodford et al. 2008, C. Bowden in litt. 2008). At the 2014 Conference of the Parties of the Convention on Migratory Species, a set of guidelines to address poisoning was formally adopted (Ogada et al. 2015).
Conservation and Research Actions Proposed
Establish legal protection for this species, particularly in West Africa. Monitor remaining populations including at colonies, perhaps through a pan-African monitoring mechanism (Rondeau and Thiollay 2004). Conserve remaining populations within protected areas. Protect breeding colonies. Maintain remaining wild ungulate herds within protected areas. Raise awareness amongst pastoralists of the dangers of using poisons for pest control. Discourage the use of diclofenac for veterinary purposes in countries where this does not already take place (BirdLife International 2007). Lobby governments to outlaw the marketing and sale of diclofenac for veterinary purposes (BirdLife International 2007). A number of recommendations were produced at the 2012 Pan-Africa Vulture Summit (Botha et al. 2012, Ogada et al. 2015): 1) Regulate import, manufacture and sale of poisons; 2) Legislate and enforce measures to prosecute those involved in illegal killing and trade in vulture species; 3) Protect and effectively manage breeding sites; 4) Ensure new energy infrastructure is 'vulture-friendly' and modify existing unsafe infrastructure; 5) Support activities to conserve vulture populations, including research and outreach activities.
