Martial eagles (Polemaetus bellicosus) are the largest eagles in Africa, but they are currently classified as Endangered by the IUCN due to a variety of threats, including shooting, poisoning, electrocution, and habitat alteration. This blog post will explore the key reasons why these magnificent birds are facing the risk of extinction.
Hunting and Poisoning by Farmers and Ranchers
One of the primary threats to martial eagles is the direct persecution by local farmers and ranchers. These birds are often seen as a threat to livestock, leading to them being shot or poisoned. In Namibia, for example, the martial eagle population has declined by 80% over a five-year period, with only around 350 pairs remaining in the country.
Electrocution from Nesting on Power Lines

Martial eagles are known to use power line supports for nesting, particularly in the Karoo region of South Africa. However, this behavior puts them at risk of electrocution, which can lead to their death or injury.
Drowning from Attempting to Drink at Steep-Sided Reserves
Martial eagles are sometimes found drowned in steep-sided water reserves, as they attempt to drink from these sources. This is a significant threat, especially in areas where natural water sources have been altered or removed.
Starvation from the Extermination of Common Food Sources
Martial eagles are apex predators, feeding on a variety of prey including mammals, birds, reptiles, and other predators. However, the extermination of these common food sources, often due to human activities, can lead to starvation and a decline in the eagle population.
Habitat Alteration and Disturbance
Habitat alteration, including the expansion of agriculture and aquaculture, can disturb the preferred environments of martial eagles, leading to conflicts with farmers as the eagles may consume domestic animals. This habitat disturbance can also disrupt the eagles’ breeding and hunting patterns, further contributing to their decline.
Conservation Efforts
Despite the numerous threats facing martial eagles, there are ongoing conservation efforts to protect this species. For example, the Lewa Wildlife Conservancy in Kenya is working to raise awareness and implement measures to safeguard the martial eagle population. Additionally, the martial eagle is listed in the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), which regulates the trade of this species to ensure its sustainability and protection.
In conclusion, the martial eagle is an endangered species due to a combination of factors, including hunting, poisoning, electrocution, drowning, starvation, and habitat alteration. Continued conservation efforts and the implementation of protective measures are crucial to ensuring the survival of this magnificent bird for future generations.
