Etymology
The common name "hooded vulture" stems from the fact that the vulture has a small patch of downy feathers that runs along the back of its neck to the crown of its head, making it look like it is wearing a fluffy, cream-colored hood. The scientific name, ''Necrosyrtes monachus,'' can be broken down into 3 sections: "necro", since it feeds on carrion; "syrtes" which means "quicksand" or "bog" and "monachus" which is Latin for "monk" and relates to the hood of the vulture.

This vulture is typically unafraid of humans, and frequently gathers around habitation. It is sometimes referred to as the “garbage collector” by locals. In Ghanaian universities, a significantly higher number of hooded vultures exist in the residential parts of the campus relative to the non-residential parts, and densities are correlated with the academic calendar, with numbers of individuals increasing during school terms.
45% of students at these campuses are defecated on by hooded vultures at least once a month, according to interviews.
Southern African hooded vulture populations have smaller home ranges than most other Old World vulture species for which data exists, though less is known about home ranges of East and West African populations.
They are most active during the day, and their ranges are smaller in the dry breeding season, when their movement is constrained by a nest site location to which they must return regularly to incubate their eggs and provision their fledglings.
In both the northern and southern hemisphere populations, breeding takes place in the dry summer season.
They prefer to build nests in well-foliaged trees along watercourses, with the nest placed a prominent fork within the tree canopy at an average height of over 15m.
They have however also been observed in a variety of biomes, some where tall trees are rare. They have been recorded in open grasslands, deserts, wooded savanna, forest edges and along coasts.
They tend to occur in higher densities where populations of larger ''Gyps'' vultures are low or nonexistent.
It occurs up to 4,000 m, but is most numerous below 1,800 m.
Hooded vultures lay a clutch of one egg, and the 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.
Measurements of nesting success at the
Olifants River Private 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.
Population trends
While the populations in Gambia are relatively stable, it is declining almost everywhere else in its range at an average rate of 83% (range 64-93%) over 53 years (3 generations).
Its total population is estimated at a maximum of 197 000 individuals. Some declines have been reported to have occurred in only 20 years, almost approaching the speed and extent of the
Asian vulture crisis of the 1990s.
The highest regional density of hooded vultures is in western Gambia.
Status and threats
The species has been uplisted from its previous IUCN status of endangered to critically endangered, since the species is going through a very steep decline in population, owing to various factors including poisoning, hunting, habitat loss and degradation of habitat.
Hunting is the most well-known threat to the species, however, poisoning has been shown to have the highest impact on the population. Poisoning of the species has been both unintentional and intentional, with unintentional poisoning being caused through the poisoning of other animals which the species feeds on. Hunting on the other hand is caused by vultures being used by people in traditional medicine and cultural beliefs and as a food source, particularly in West and southern Africa.
Researchers interviewed vendors in street markets in northern Nigeria who were selling parts or entire carcasses of hooded vultures as well as other African vulture species (though hooded vultures made up 90% of vultures on sale). They found that 40% of traders were selling the vultures for spiritual healing and 25% for human consumption.
Many West and southern African cultures believe vulture body parts cure a range of physical and mental illnesses, improve success in gambling and business ventures, or increase intelligence in children.
Consumption of vultures as bushmeat in Nigeria and Ivory Coast may be of regional concern, but smoked vulture meat is traded and consumed internationally.

Conservation action
Raptors are protected in many West African and Northeastern countries and in South Africa under the United Nations Convention on the Conservation of Migratory Species of Wild Animals (CMS), in the Memorandum of Understanding on the Conservation of Migratory Birds of Prey in Africa and Eurasia (the ‘Raptors MoU’). This plan includes the Hooded vulture.
Systematic monitoring and protection schemes for African raptors, including the hooded vulture, exist and some populations occur within protected areas.
It has been suggested that the best way to slow the decline of vulture populations in Africa, and avoid a massive decline on the scale of the
