Martial eagle facts begin with scale. This is the largest eagle in Africa by length and wingspan — a bird whose shadow crossing a Uganda kob herd on the Kasenyi Plains signals genuine apex-predator status. Dark upperparts, white-spotted underwing coverts, and a massive yellow gape distinguish adults; juveniles wear paler, streaked plumage for years before acquiring full adult dress. Listed as Endangered by the IUCN, every healthy territory in Uganda's protected savannah matters. This guide covers essential behaviour, habitat, and where to see detail, plus game-drive experiences across Uganda's savannah parks.
What Is a Martial Eagle?
The martial eagle (Polemaetus bellicosus) is a large booted eagle and the sole member of genus Polemaetus. Found across sub-Saharan Africa in open savannah and woodland, it hunts mammals, birds, and reptiles from soaring flight or elevated perches. Unlike the fish-eating African fish eagle, martial eagles are land hunters of the open plains — a raptor whose presence on a Murchison or Queen Elizabeth game drive elevates any morning.
Scientific Classification

- Phylum: Chordata
- Class: Aves
- Order: Accipitriformes
- Family: Accipitridae
- Genus: Polemaetus
- Species: Polemaetus bellicosus
Physical Appearance
Adults are powerfully built with dark brown upperparts, a pale or rufous-streaked breast band, and white-spotted underwing coverts visible in flight. The head may show a slight crest when alert. Eyes are yellow; the massive hooked bill and bare yellow gape emphasise killing power. In soaring flight the broad wings and relatively short tail create a distinctive silhouette against blue savannah sky.
Size and Wingspan
Body length ranges from roughly 78 to 96 centimetres. Wingspan typically reaches 1.9 to 2.6 metres — among the largest of any eagle worldwide. Females exceed males in size, as in most large raptors.
Weight
Males generally weigh 3.0 to 4.5 kilograms; females 4.5 to 6.5 kilograms. The thick legs and talons are adapted for grounding prey — not grasping slippery fish.
Juvenile Plumage
Immature martial eagles wear paler, heavily streaked underparts and browner overall tones. Full adult plumage may take four to seven years. Juveniles disperse widely before establishing territories — pale soaring birds on dawn drives are often immatures still perfecting hunting skills.
Africa's Largest Eagle
Martial eagles exceed crowned eagles in wingspan and rival or surpass them in bulk. They are larger than African fish eagles, bateleurs, and tawny eagles — a distinction birders and casual safari travellers alike register instantly when a bird crosses the windscreen at low altitude.
Distribution in Uganda
Martial eagles occur in savannah and open woodland parks nationwide where prey and nest trees persist. Prime sites include Murchison Falls, Queen Elizabeth, Lake Mburo, and Kidepo Valley. They are absent from dense montane forest — Bwindi's crowned eagle fills that niche.
How Martial Eagles Hunt
Hunting combines high soaring to survey territory, perch watching from tall trees, and explosive stoops onto prey. Attacks on guineafowl, hares, and small antelope can be seen from vehicles on open plains if luck and timing align. Read the full story on our behaviour page.
Diet Overview
Prey spans guineafowl, francolins, hares, mongoose, monitor lizards, snakes, and mammals to the size of small antelope and vervet monkeys. Carrion and pirated kills supplement the menu. See diet and feeding ecology for prey lists and seasonal shifts.
Reproduction at a Glance
Pairs are monogamous with vast territories. Nests are enormous stick platforms in the tallest savannah trees. Clutches are usually a single egg; chick dependency extends many months — among the slowest breeding schedules of any eagle, amplifying conservation concern.
Lifespan
Wild martial eagles may live 12 to 16 years, with longer records in captivity. Territory quality, freedom from poisoning, and nest-tree availability largely determine longevity.
Conservation Status
The IUCN lists the martial eagle as Endangered. Continental declines reflect poisoning, electrocution, habitat loss, and persecution. Uganda's national parks provide critical refuge — explored on our conservation page.
