Martial Eagle

The Martial Eagle (Polemaetus bellicosus), a formidable raptor, reigns over the sub-Saharan skies. This solitary species, the sole member of its genus, is distinguished by its impressive size and power. With feathered tarsi characteristic of the booted eagle subfamily, it is one of the largest of its kind. The Martial Eagle is an apex predator, soaring high to stoop upon a diverse array of prey, from mammals to reptiles.

Identification Tips

Adult Martial Eagles exhibit a dark brown plumage on their upperparts, head, and upper chest, with occasional lighter feather edges. Their underparts are white, marked with sparse blackish-brown spots. In flight, their long broad wings and short tail give them a distinctive silhouette. Juveniles are paler with a greyish mottled appearance and take up to seven years to acquire their adult plumage.

Habitat

The Martial Eagle favors wooded belts within open savanna landscapes, avoiding dense forests and arid deserts. It is often found perched in an upright position in large trees, surveying its territory.

Distribution

This eagle's range spans across sub-Saharan Africa, with higher densities in southern and parts of east Africa. It is more sporadic in west Africa, with notable populations in protected areas such as South Africa's Kruger National Park.

Behaviour

Martial Eagles spend a significant portion of their day aloft, soaring at great heights. They are solitary outside of the breeding season and exhibit a preference for less disturbed areas, likely due to the abundance of prey and aversion to human activity.

Song & Calls

The Martial Eagle is not a frequent vocalizer, but it does emit a low mellow whistle as a contact call and a louder, trilling call during territorial displays.

Breeding

Breeding occurs at various times across their range, with nests built high in large trees. They lay usually one egg, with the female performing most of the incubation. Fledglings remain dependent on their parents for several months post-fledging.

Similar Species

The Black-chested Snake Eagle may be confused with the Martial Eagle but is significantly smaller with different coloring and flight patterns. Juvenile Martial Eagles may be mistaken for juvenile Crowned Eagles but differ in wing and tail proportions.

Diet and Feeding

Martial Eagles are opportunistic predators, with a diet comprising mammals, birds, and reptiles. They are known for hunting from a high soar, using their keen eyesight to spot prey from several kilometers away.

Conservation Status

The Martial Eagle is currently classified as Endangered by the IUCN, with populations declining due to factors such as persecution, habitat destruction, and collisions with power lines. Conservation efforts focus on education and the expansion of protected areas.
