What is a martial eagle?
The martial eagle (Polemaetus bellicosus) is a large, long-winged eagle inhabiting sub-Saharan Africa's dry grasslands, scrublands, and scattered woodlands. It is Africa's largest eagle, with a length of up to 96 cm and a weight of up to 6.5 kg.
Martial eagles have brown heads, throats, and wings. Their underparts are white with dark spots, and their tail feathers are striped with black. Adults grow to about 80 cm in length and weigh between 3.1 and 6.2 kg, with wingspans ranging from 1.9 to 2.6 meters.
They are apex predators, consuming various prey, including birds, poultry, small livestock, antelopes, hyraxes, rabbits, snakes, lizards, and monkeys. They hunt from the air or a high perch and can dive at 230 km per hour.
Once common, martial eagle populations have declined due to hunting and poisoning. The IUCN has listed it as an endangered species since 2020.

Where does the martial eagle live?
The martial eagle (Polemaetus bellicosus) lives in sub-Saharan Africa, in dry grassland, scrubland, and scattered woodland habitats. They are one of the largest birds of prey, with a length of up to 96 cm and a weight of up to 6.5 kg, and the largest eagle in Africa. They build large nests in tall trees or on electrical towers, alternating between two nests from year to year. The IUCN has listed the martial eagle as an endangered species since 2020 due to population declines from hunting and poisoning.

What does a martial eagle look like?
Martial eagles have brown heads, throats, and wings. Their underparts are white with dark spots, and their tail feathers are striped with black on the undersides. Easily distinguished by these features, they also have a large hooked black bill, curved talons, and large wings.
Most adults grow to about 80 cm (32 inches) in length and weigh between 3.1 and 6.2 kg (6.8 and 13.7 pounds), though some may be larger. Their large wingspans can range from 1.9 to 2.6 meters (6.2 to 8.5 feet). Martial eagles also have bright yellow eyes.

What do martial eagles eat?
Martial eagles are apex predators that consume various prey, but they mostly prefer medium-sized vertebrates, including poultry and smaller livestock like young goats. They also eat small antelopes and hyraxes, rabbits, snakes and lizards, and even monkeys. Martial eagles hunt from the air or a high perch, spotting prey from kilometers away before diving to attack at speeds of up to 230 km (143 miles) per hour. They use their talons to kill larger prey.

How do martial eagles hunt their prey?
Martial eagles, considered apex predators, are known for their hunting skills in the ecosystems they inhabit. They can spot prey from several kilometers away, using their sharp eyesight to locate medium-sized vertebrates, including birds, small antelopes, hyraxes, rabbits, snakes, lizards, and even monkeys.
These eagles employ two main hunting strategies: hunting from the air or from a high perch. When diving to attack, a martial eagle can descend at speeds of up to 230 km (143 miles) per hour, often killing their prey on impact. For larger prey that survive the initial assault, the eagle uses its talons to finish the job.

Why are martial eagles important to their environment?
Martial eagles are important to their environment because they are apex predators in their ecosystems. They consume a variety of prey, including birds and medium-sized vertebrates like poultry, small livestock, antelopes, hyraxes, rabbits, snakes, lizards, and monkeys. They hunt from the air or from a high perch, spotting prey from kilometers away before diving to attack at speeds of up to 230 km per hour.
However, the International Union for Conservation of Nature (IUCN) has listed martial eagles as an endangered species since 2020, owing to declines in the bird’s population. Martial eagles are often hunted, trapped, and poisoned by commercial farming operations to keep the birds from attacking a wide range of domesticated birds and other livestock.

Martial eagle, (Polemaetus bellicosus), large, long-winged eagle inhabiting dry grassland, scrubland, and scattered woodland habitats of sub-Saharan Africa. The martial eagle is one of the largest birds of prey in the world, and, with a length reaching up to 96 cm (37 inches) long and a weight up to 6.5 kg (14 pounds), it is the largest eagle in Africa. Once common throughout their range, hunting and poisoning decimated martial eagle populations during the early 21st century.
Form and function
Martial eagles have brown heads, throats, and wings. Their underparts are white with dark spots, and the undersides of their tail feathers are striped with black. The species is easily distinguishable by these features along with their large hooked black bill, curved talons, and large wings. Most adults grow to about 80 cm (32 inches) in length and weigh between 3.1 and 6.2 kg (6.8 and 13.7 pounds), although some may be larger. They have large wingspans that can range from 1.9 to 2.6 meters (6.2 to 8.5 feet).
Martial eagles are monogamous birds that become sexually mature about age four. They construct large nests (which range from 1.2 to 1.8 meters [4 to 6 feet] in diameter]) in tall trees or on electrical towers (power pylons) set between 6 and 24 meters (20 and 80 feet) above the ground. The nests are lined with leaves and sticks. Pairs of eagles build two nests typically, between which they alternate from one year to the next. Breeding may happen throughout the year, and the female usually lays one egg, which is incubated for about 45 days before the young bird hatches. Both parents feed and protect their chick for almost two months. Although the young bird makes its first flight some 90–100 days after hatching, it will not become fully independent until 2–3 years later.

Martial eagles are often considered apex predators in the ecosystems they inhabit. They consume a wide variety of prey but mostly prefer birds and other medium-sized vertebrates, including poultry, smaller livestock (such as young goats), small antelopes and hyraxes, rabbits, snakes and lizards, and even monkeys. Martial eagles hunt from the air or from a high perch. They can spot their prey from a distance of several kilometers before diving to attack. A diving martial eagle can descend at 230 km (143 miles) per hour, killing many of its prey upon impact. The bird uses its talons to kill larger prey that survive this high-speed assault.
Conservation status
The International Union for Conservation of Nature and Natural Resources (IUCN) considered the martial eagle as a species of least concern in 2008; however, owing to precipitous declines in the bird’s population, the IUCN has listed it as an endangered species since 2020. Martial eagles are often hunted, trapped, and poisoned by commercial farming operations to keep the birds from attacking a wide range of domesticated birds and other livestock, and these activities are largely responsible for the species’ plunging numbers. Lesser threats include habitat loss and degradation from pollution, increases in mortality among the young due to nest disturbances, and decreases in food due to population declines among its prey. Although some birds nest in protected areas, their territories are so large that they often need to venture into unprotected areas to hunt, which places them at risk. The species’ high mortality rate is also exacerbated by its habit of nesting on electrical towers, and each year many birds are electrocuted.
