Population justification: The species's global population has been estimated at 270,000 individuals.

Trend justification: The most recently published data on this species's population suggests the species has declined extremely rapidly, with a median estimate of 90% (range: 75-95%) over three generations (55 years) (Ogada et al. 2016). Declines have exceeded 90% in West Africa (Thiollay 2006), and have also occurred in other parts of the range including Sudan (Nikolaus 2006) and Kenya (M. Virani in litt. 2006), but populations are apparently stable in Ethiopia (Nikolaus 2006) and Tanzania (D. Peterson in litt. 2006). Virani et al. (2011) documented an apparent decline of c. 52% over c.15 years in the numbers of Gyps vultures present in the Masai Mara (Kenya) 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). As these are visiting individuals from a wide-ranging population, 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).
