This species is classified as Near Threatened because it is suspected to have undergone moderately rapid declines during the past three generations (41 years) owing to habitat loss and incidental poisoning and pollution, and is consequently believed to approach the threshold for classification as Vulnerable.

Geographic Range [top]

Range Description: Terathopius ecaudatus has an extensive range across much of sub-Saharan Africa (from southern Mauritania, Senegal, southern Mali and Guinea east to southern Sudan, northern South Sudan, Ethiopia and west Somalia and south to Namibia, Botswana and northern and north-eastern South Africa), and also occurs in south-west Arabia (south-west Saudi Arabia and Yemen). Its global population is estimated to be 10,000-100,000 individuals (Ferguson-Lees and Christie 2001). There have been significant population declines and/or range contractions suspected in many regions, including Botswana (S. Tyler in litt. 2009), Côte d'Ivoire (del Hoyo et al. 1994), Kenya (N. Baker in litt. 2005, Ogada 2009), Namibia (del Hoyo et al. 1994), Nigeria (an estimated decline of at least 50 % in 30 years and now essentially confined to protected areas) (P. Hall in litt. 2005, 2009, O. J. Daniel in litt. 2009), Somalia (A. Ajama in litt. 2009), South Africa (Ferguson-Lees and Christie 2001, S. Thomsett in litt. 2005), Sudan (del Hoyo et al. 1994), parts of Zambia (P. Leonard in litt. 2005), Zimbabwe (del Hoyo et al. 1994), and possibly parts of Tanzania (J. Wolstencroft in litt. 2005), in some areas, however, the species is not declining and remains widespread and common (N. Baker in litt. 2005, N. Cordeiro in litt. 2005, F. Dowsett-Lemaire and R. Dowsett in litt. 2005).

Population: The population is estimated to number in the tens of thousands.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: It inhabits open country, including grasslands, savanna and subdesert thornbush from sea level to 4,500 m but generally below 3,000 m (Ferguson-Lees and Christie 2001). It is generally considered resident but some adults as well as immatures are nomadic (Ferguson-Lees and Christie 2001). It takes both live and dead food, mostly mammals and birds but also some reptiles, carrion, insects and occasionally birds' eggs and crabs, foraging over a huge range (55-200 km2) (Ferguson-Lees and Christie 2001). The nest is built in the canopy of a large tree, and breeding is chiefly September-May in West Africa, throughout the year in East Africa and December-August in southern Africa (Ferguson-Lees and Christie 2001).

Systems: Terrestrial

Threats [top]

Major Threat(s): Putative reasons for declines vary, but include poisoned baits, pesticides, trapping for international trade, nest disturbance from spreading human settlements, and increased intensification and degradation of agricultural land (Ferguson-Lees and Christie 2001, N. Baker in litt. 2005, S. Thomsett in litt. 2005). The major cause of the decline seems to be almost entirely poisoning by a few large-scale commercial farmers, but poisoning is also a problem in tribal small-stock farming communities.

Conservation Actions [top]

Conservation Actions: Conservation Actions Underway
None is known.

Conservation Actions Proposed
Implement education and awareness campaigns across its range to reduce the use of poisoned baits. Carry out regular population monitoring across its range.
