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.
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 poles, 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. 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.
