This species has a very large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size may be moderately small to large, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Behaviour The species has a fragmented distribution across the southern Palearctic and Indomalayan regions, and is marginally Afrotropical (45°N to 10°S). It is locally uncommon to rare and in decline across its range. The species is resident throughout its range, although juveniles will disperse up to 200km with individuals occasionally wandering further afield and passing through key migration routes (Ferguson- Lees and Christie, 2001; Shirihai et al., 2000). Habitat The species occupies mountainous, rocky, arid to semi-moist habitat, from sea level to 1500m, but up to 3000m in Africa and 3750m in the Himalayan foothills. It generally occurs in open areas but also occupies woodland. Juveniles often occupy areas near large water bodies (Ferguson- Lees and Christie, 2001). Diet The eagle’s prey principally comprises small or medium-sized birds, but it will also take mammals, some reptiles, insects and rarely, carrion (Ferguson- Lees and Christie, 2001). Breeding Site The nest is composed of sticks, up to 2m in diameter, located on remote cliff ledges or in a large tree. The nest is re-used in successive years. Breeding occurs from January to July in the west of the range, and from November to September in the Indomalayan region (Ferguson- Lees and Christie, 2001).
Since the 1950’s the species has declined throughout its range. It was affected by pesticide use in the mid-20th Century, and since then populations have not recovered to their pre-organochlorine levels. The species is persecuted by hunters and pigeon-fanciers in the west of its range and juveniles suffer high mortality from collisions with power lines (Rollan, et al., 2010). Declining prey availability, increasing human disturbance and poaching at nest sites, and agricultural intensification are thought to be key factors in the species’ decline (Ferguson- Lees and Christie, 2001; del Hoyo et al., 1994).
