Tawny Eagle

The Tawny Eagle is a medium-sized, sturdily built eagle of Africa's open country, notable for the wide variation in its plumage color, which ranges from pale buff or almost white to dark chocolate-brown, even among birds from the same population. Most individuals show some tawny or rufous tone, giving the species its name.

It has a relatively small head for its body size, broad wings, and a short, rounded tail, with a yellow gape line that reaches roughly to the eye — an important feature for separating it from similar eagles.

Key field marks

• Highly variable plumage from pale buff to dark brown, usually with a tawny cast
• Yellow gape line extending to about the eye (not beyond it)
• Relatively small head and bill compared to body size
• Broad wings and short tail typical of open-country soaring eagles

Similar species

The Steppe Eagle, a Palearctic migrant that winters in Africa, is very similar but generally larger, with a yellow gape line extending back behind the eye and more evenly barred flight feathers. Juvenile Tawny Eagles show pale wing bars and a paler rump, which fade with age, and can also resemble juveniles of other Aquila eagles.

Range

Widespread across sub-Saharan Africa; a closely related population in the Indian subcontinent is treated by some authorities as a separate species (Indian Spotted Eagle relatives), though true Tawny Eagle numbers there have declined sharply.

Habitat

Favors open savanna, thornveld, semi-desert, and grassland with scattered trees for nesting and perching.

Movement

Mostly sedentary but can be locally nomadic, following rainfall, prey abundance, and large herbivore herds that attract carrion opportunities.

Behavior

The Tawny Eagle is a highly opportunistic feeder, soaring for extended periods to scan for carrion and often being among the first scavengers to arrive at a carcass. It readily hunts live prey as well, and is a persistent kleptoparasite, aggressively chasing other raptors to force them to drop or abandon their catch.

Voice

Gives harsh, barking calls, most often around the nest or during territorial disputes.

Nesting

Builds a large stick nest in a tree, typically laying one to three eggs; pairs may reuse and enlarge the same nest over successive years.
