Red List Category & Criteria: Vulnerable A2acde+3cde+4acde ver 3.1
Year Published: 2013
Date Assessed: 2013-11-01

Reviewer(s): Butchart, S.
Contributor(s): Ajama, A., Baker, N., Brewster, C., Brown, C., Daniel, O., Hall, P., Tyler, S., Coetzee, R., van Eeden, R., Rainey, H. & Thomsett, S.
Facilitator/Compiler(s): Butchart, S., Ekstrom, J., Harding, M. & Symes, A.
Justification:
This species has been uplisted to Vulnerable because it is suspected to have undergone rapid declines during the past three generations (56 years) owing to deliberate and incidental poisoning, habitat loss, reduction in available prey, pollution and collisions with power lines. Further information on trends across its large range may lead to its further uplisting to Endangered in the future.

History:
2012 Near Threatened

Geographic Range [top]

Range Description:Polemaetus bellicosus has an extensive range across much of sub-Saharan Africa, from Senegal and the Gambia east to Ethiopia and north-west Somalia and south to Namibia, Botswana and South Africa. It is generally scarce to uncommon or rare, but is reasonably common in some areas (Ferguson-Lees & Christie 2001). It is suspected to have undergone declines in much of its range, including West Africa (Thiollay 2006, H. Rainey in litt. 2013), Namibia (C. Brown in litt. 2009), Nigeria (P. Hall in litt. 2009), Kenya (S. Thomsett in litt. 2013) and South Africa (R. van Eeden in litt. 2013).

Population [top]

Population: The global population has not been quantified, but was estimated as probably 'in tens of thousands' by Ferguson-Lees and Christie (2001), while the South African population was believed to be no larger than 600 pairs (Barnes 2000).

Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: It inhabits open woodland, wooded savanna, bushy grassland, thornbush and, in southern Africa, more open country and even subdesert, from sea level to 3,000 m but mainly below 1,500 m (Ferguson-Lees & Christie 2001). The main prey is sizeable mammals, birds and reptiles (Ferguson-Lees & Christie 2001).

Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): The species suffers from direct persecution (shooting and trapping) by farmers, indirect poisoning (these two threats by far the most important causes of losses), drowning in sheer-walled reservoirs, electrocution on power lines, and habitat alteration and degradation (Global Raptor Information Network 2009). Poisoning is largely carried out by a few large-scale commercial farmers, but is also a problem in tribal small-stock farming communities. Deforestation may be having less of an impact on this species than on other large eagles as it can utilise man-made structures for nesting. Large mammal populations in West Africa are highly threatened and the threats are likely to increase in the future as human populations continue to grow. (H. Rainey in litt. 2013).  Reduction in natural prey may lead to an increase in predation on domestic animals which may in turn lead to increased persecution by farmers. In some areas birds may be taken for use in traditional medicine, and parts have been found in muthi markets in Johannesburg (R. Coetzee in litt. 2013). The majority of protected areas in Kenya are too small to hold a single pair (S. Thomsett in litt. 2013), and the size of territory means that birds nesting in protected areas will generally forage far outside them, making them more vulnerable to persecution. In South Africa the highest declines were observed in areas with the greatest increase in temperature and areas with high densities of power lines, probably due to collisions and electrocutions. In Kruger National Park, higher densities of elephants were related to larger declines in Martial Eagles, probably as a result of a reduction in nesting sites or changes in habitat quality (R. van Eeden in litt. 2013).

Conservation Actions [top]

Conservation Actions: Conservation Actions Underway
A system to compensate farmers for stock losses has been initiated in South Africa.

Conservation Actions Proposed
Introduce programmes combining awareness campaigns and compensation to farmers for stock losses across the species's range. Install anti-electrocution devices on electricity pylons. Implement education and awareness campaigns across its range to reduce the use of poisoned baits. Carry out regular population monitoring across its range.
