||67-70 cm Small, scruffy-looking, mostly brown vulture, with long thin bill, bare crown, face and foreneck, conspicuous ear-holes, and downy nape and hindneck. Perches hunched with wings drooping. Sexes alike. Juvenile usually with face pale blue and hood of short down dark brown rather than beige. Similar spp N. monachus is smaller and finer-billed compared to Torgos tracheliotus. Juvenile similar to juvenile Neophron percnopterus, but tail not pointed and head has down rather than contour feathering.

This vulture is listed as Critically Endangered. Recently published evidence suggests the population is experiencing an extremely rapid decline owing to indiscriminate poisoning, trade for traditional medicine, hunting, persecution and electrocution, as well as habitat loss and degradation.

|Range Description:||This species is widespread in sub-Saharan Africa; from Senegal (with higher densities in the West, for at least the southern part of the country, with possibly 2,350-2,700 pairs in the Ziguinchor Départment [B. Bargain in litt. 2016]) and southern Mauritania east through southern Niger and Chad, to southern Sudan, South Sudan, Ethiopia and western Somalia, southwards to northern Namibia and Botswana, and through Zimbabwe to southern Mozambique and north-eastern South Africa (Ferguson-Lees and Christie 2001). The species is generally sedentary, with some dispersal by non-breeders and immature birds, and movements in response to rainfall in the Sahel of West Africa (Ferguson-Lees and Christie 2001). Data and observations of varying coverage and quality from various parts of its range suggest that the species is undergoing a very rapid decline in its global population (Ogada and Buij 2011, Ogada et al. 2016). Trends in Uganda are difficult to detect owing to strong annual variations (Pomeroy et al. 2012) whilst in coastal Gambia the species is reported to remain relatively abundant, and may have the highest densities left of this species (Barlow and Fulford 2013, Jallow et al. 2016). Following evidence of declines across its range, the total population has been estimated at a maximum of 197,000 individuals (Ogada and Buij 2011). |

|Habitat and Ecology:||The species is often associated with human settlements north of the Equator, but is also found in open grassland, forest edge, wooded savanna, desert and along coasts; and tends to occur at higher densities in areas where populations of larger Gyps vultures are low or nonexistent (Ferguson-Lees and Christie 2001. K. Bilstein in litt. 2016). It occurs up to 4,000 m, but is most numerous below 1,800 m. It feeds mainly on carrion, but also takes insects (and will congregate in large numbers during insect emergences [Smalley 2016]). In West Africa and Kenya it breeds throughout the year, but especially from November to July. Breeding in north-east Africa occurs mainly in October-June, with birds in southern Africa tending to breed in May-December. It is an arboreal nester, favouring Ceiba pentandra in Senegal (B. Bargain in litt. 2016), and lays a clutch of one egg. Its incubation period lasts 46-54 days, followed by a fledging period of 80-130 days. Young are dependent on their parents for a further 3-4 months after fledging (Ferguson-Lees and Christie 2001). Measurements of nesting success at the Oifants River Provate Nature Reserve, South Africa showed, success of 0.44-0.89 offspring per pair per year in 2013 and 0.50-0.67 offspring per pair per year in 2014 (Monadjem et al. 2016). |

Major threats to this species include non-target poisoning, capture for traditional medicine and bushmeat (McKean et al. 2013), and direct persecution (Ogada and Buij 2011, Ogada et al. 2016). In Nigeria, a survey of medicinal traders found that Hooded Vulture was the most commonly traded species of vulture, with 90% of all vulture parts traded belonging to the species (Saidu and Buij 2013). And across West and Central Africa the species is one of the most heavily traded, with an estimated 5,850-8,772 individuals traded over a six-year period in West Africa (Buij et al. 2015). Hooded Vulture meat is reportedly sold as chicken in some places. Intentional poisoning of vultures may be carried out in some areas by poachers in order to hide the locations of their kills, but in Senegal at least vultures to receive a form of cultural protection from such killing because they are the totem for some families (B. Bargain in litt. 2016). Secondary poisoning with carbofuran pesticides at livestock baits being used to poison mammalian predators is also an issue in East Africa (Otieno et al. 2010, C. Kendall in litt. 2012, Roxburgh and McDougall 2012). Declines have also been attributed to land conversion through development and improvements to abattoir hygiene and rubbish disposal in some areas (Ogada and Buij 2011), and, in Senegal, a decline in the number of their favourite nesting tree species (B. Bargain in litt. 2016). The species may also be threatened by avian influenza (H5N1), from which it appears to suffer some mortality and which it probably acquires from feeding on discarded dead poultry (Ducatez et al. 2007), although this is not well substantiated (C. Kendall in litt. 2016).
