Geographic Range [top]

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).

Population [top]

Population:Given evidence of recent declines in various parts of its range, this species's population is estimated to number a maximum of 197,000 individuals.

Trend Justification:  Recently published data shows that this species's population is declining rapidly with an estimated 83% decline (range 64-93%) over three generations (53 years) (Ogada et al. 2016).

Current Population Trend:Decreasing

Habitat and Ecology [top]

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).

Threats [top]

Major Threat(s): 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).

Conservation Actions [top]

Conservation Actions: Conservation and Research Actions Underway
This widespread species occurs in a large number of protected areas. The species is being surveyed in parts of its range, including The Gambia, Tanzania, Kenya, and South Africa with plans for larger scale monitoring. Movement studies have been undertaken in several countries to assess ranging behavior and impact of commensalism on range size (C. Barlow in litt. 2016, C. Kendall in litt. 2016). The Hawk Conservancy along with the Endangered Wildlife Trust are currently working on providing training and equipment for anti-poisoning teams so that field staff will have the skills and equipment to respond to a neutralise poisoned carcasses (C. Murn in litt. 2016). It is listed as Critically Endangered in the Eskom Red Data Book of Birds of South Africa, Lesotho and Swaziland (Allan 2015), and Endangered in Namibia and Uganda (Brown and Simmons 2015, WCS 2016). A multi-species action plan is in preparation for African-Eurasian vultures.

Conservation 
and Research Actions Proposed
Carry out systematic surveys throughout the species's range to acquire a more accurate population estimate and monitor trends. Raise awareness of the species's plight and the impact of hunting and persecution. Monitor rates of land-use change across its range. Monitor effects of poisoning on the species and its use in muti trade and for meat (C. Kendall in litt. 2012). Reduce human-carnivore conflict that motivates carrion poisoning, and monitor potential impact of lead poisoning from hunting activities on population - particularly targeted at farmers to reduce persecution and people in urban areas where the species can occur (C. Kendall in litt. 2016, K. Bildstein in litt. 2016). A number of recommendations were produced at the 2012 Pan-Africa Vulture Summit (Botha et al. 2012, Ogada et al. 2016): 1) Regulate import, manufacture and sale of poisons; 2) Legislate and enforce measures to prosecute those involved in illegal killing and trade in vulture species; 3) Protect and effectively manage breeding sites; 4) Ensure new energy infrastructure is 'vulture-friendly' and modify existing unsafe infrastructure; 5) Support activities to conserve vulture populations, including research and outreach activities.
