The hooded vulture (Necrosyrtes monachus) is an Old World vulture in the order Accipitriformes, which also includes eagles, kites, buzzards and hawks. It is the only member of the genus Necrosyrtes and is native to sub-Saharan Africa. It is a scruffy-looking, small vulture with dark brown plumage, a long thin bill, bare crown, face and fore-neck, and a downy nape and hind-neck. It typically scavenges on carcasses. Although it remains a common species in the lower region of Casamance, some areas of The Gambia, and Guinea-Bissau; other regions such as Dakar, Senegal show more than 85% losses in population over the last 50 years[2]. Threats include poisoning, hunting, and loss of habitat, and the International Union for Conservation of Nature has rated its conservation status as "critically endangered".

Description[edit]

The hooded vulture is a typical vulture, with a head that is usually white, but flushes red when agitated[3] and a greyish “hood”. It has fairly uniform dark brown body plumage. It has broad wings for soaring and short tail feathers. It is a small species compared to most vultures. Female Vultures of the hooded variety are also often seen to have longer eyelashes than the males. They have strong feet and are monogamous creatures.

It breeds in a stick nest in trees (often palms) in much of Africa south of the Sahara, laying one egg. Birds may form loose colonies. The population is mostly resident. This is one of the smaller vultures of the Old World. They are 62–72 cm (24–28 in) long, have a wingspan of 155–165 cm (61–65 in) and a body weight of 1.5–2.6 kg (3.3–5.7 lb).[4]

Ecology[edit]

Like other vultures it is a scavenger, feeding mostly from carcasses of dead animals and waste which it finds by soaring over savannah and around human habitation, including waste tips and abattoirs. It often moves in flocks, and is very abundant. In much of its range, there are always several visible soaring in the sky at almost any time during the day.

This vulture is typically unafraid of humans, and frequently gathers around habitation. It is sometimes referred to as the “garbage collector” by locals.

Status[edit]

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 humans in medicine, as a food source, and for traditional medicinal and other belief uses.[5]
