Distribution: Afrotropical. Sub-Saharan Africa from MAURITANIA east to ETHIOPIA and south to NAMIBIA and SOUTH AFRICA. more....

Subspecies: Monotypic. more....

Taxonomy: Placed by some in the genus Neophron (e.g., Britton 1980, Louette 1981, Nikolaus 1987, Gore 1990) on the basis of supposed morphological similarities. However, neither the cytochrome b gene studies of Wink (1995), nor those of Lerner and Mindell (2005), based on the sequences of two mitochondrial genes and one nuclear entron, supported such a relationship. Both found that this species is probably closer to the clade of true Old World vultures, Aegypiinae, which includes Aegypius, Gyps, Sarcogyps, Torgos and Trigonoceps, than to the Neophron-Gypaetus clade, Gypaetinae. The exact relationships of Necrosyrtes to the Aegypiinae remains uncertain, pending further study, but it probably diverged rather early (3 to 5 million years ago) from it closest relative, Gyps (Wink op cit.).

Movements: Irruptive or local migrant, with juveniles dispersing from breeding areas (Bildstein 2006). Generally thought to be largely sedentary in southern Africa (Oatley et al. 1998), but movements of ringed individuals up to 200 km have been recorded (Mundy 1997). Numbers of this species increase markedly in the northern Sahel during the short rains (July-August), and these birds return to the southern Sahel during the drier months from September to December (Thiollay 1978). more....

Habitat and Habits: In West Africa and Somalia, highly commensal with man and occurs in a wide range of open, cultivated, and urban habitats; absent only from the equatorial forest zone. In the southern portions of its range, it is much less common, less frequent around human settlements, and restricted to savanna habitats within large game reserves and national parks. Its distribution in southern Africa largely coincides with two large, well-foliaged tree species, Diospyros mespiliformis and Xanthocercis zambiaca, particularly in riparian habitats (Kemp 1969, Mundy 1997). It is also very gregarious in West Africa, but in southern Africa, it is usually found singly, in pairs, or in small groups. Squires (2004) and Steyn (2005) reported that this species associates with Wild Dogs in Botswana, and in Uganda, it often occurs in the company of Marabou Storks (Carswell et al. 2005). more....

Food and Feeding Behavior: Feeds on carrion, including dead fish and small mammals, bird eggs, trash, excreta, and insects, including flying termites. Soars low over open country in search of food, or perches along edges of forests and rivers. This species is airborne earlier in the day than other vultures and is often the first to find food. It is subordinate to other vulture species at carcasses. more....

Breeding: This species breeds semi-colonially in tall trees around villages in West Africa, but nests are solitary and well concealed in southern Africa. The wide spacing of the nests suggest that the species may be territorial. The nest is a stick platform placed beneath the canopy of a tree. Both adults participate in nest-building. Clutch size is one egg. The incubation period is about 51 days, and the nestling period lasts from three to four months. Fledged chicks are still dependent upon the parents for up to six more months, so the breeding cycle can occupy the entire year (Tarboton 1990). more....

Conservation: Widespread in sub-Saharan Africa except in heavily forested and very arid areas. Populations in southern Africa have suffered a marked decline in recent years. Furthermore, Rondeau and Thiollay (2004) and Thiollay (2006) recently reported a very alarming decline in numbers in several West African countries, where it has traditonally been by far the most common vulture species. The causes of the decline are still speculative. This species is now categorized as Endangered by BirdLife International. more....

Population Estimates: The total global population was estimated at 200,000-300,000 individuals by Mundy et al. (1992), but is much lower now.
