Population justification:
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.
Trend justification: Recent data suggest this species has experienced a very rapid population decline of c.5.8% per year, equating to 92.5% (range: 88-98%) over three generations (43.32 years [Bird et al. 2020]) (Ogada et al. 2016). 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), although this species may be doing slightly better than other Gyps species in the Masai Mara as its relative abundance at carcasses has increased compared to G. africanus (Kendall et al. 2012).
