International Journal of Primatology. Around stretches of East Africa, Crowned eagles usually live in wooded areas of rocky hills and narrow riverine strips, only rarely ranging into savanna surrounding the hills.

In South Africa, they occur in both lowland and montane evergreen forest, dense woodland, and forested ravines and gorges in open savannas and thornveld.

Crowned eagles live in pairs. They are largely sedentary and usually inhabit a fixed territory throughout the year.

Crowned eagles are considered nervous, constantly alert and on edge. However, their main hunting techniques require long periods of inactivity, spent sitting on a perch.

Crowned eagles may hunt alone or in pairs and mainly kill early in the morning and in the evening prior to sundown. These beautiful hunters may locate a suitable hunting spot by listening such as via the call of the noisy vervet monkey or watching for prey activity, though may also use habitual hunting perches where they've previously had hunting successes.

They often still-hunt, wherein they drop or stoop onto prey from a branch perch. Crowned eagles are highly vocal and have a noisy, undulating display flight.

The male performs an elaborate rise-and-fall display over the forest canopy both during the breeding season and outside as a territorial proposition.

Territorial displays consist of a series of steep dives and ascents, with a few wing-flaps at the top of each climb and descending circles and figures of eight.

During descents, eagles can drop as much as 60 m ft at a time before circling back up. During this display, the male is noisy, uttering a shrill kewee-kewee-kewee while throwing his head back.

The adult female may also perform independent display flights, uttering a lower kooee-kooee-kooee. Pairs also perform visually striking mutual displays, sometimes arising from the first type or when the pairs come together after a brief absence.

While awaiting food at the nest, both the female and the young produce high kwee-kwee-kwee. Crowned eagles are carnivores and most of their diet consists of mammals.

They hunt mainly small ungulates such as duikers, chevrotains , rock hyrax and small primates such as monkeys. Birds and large lizards are taken occasionally.

Crowned eagles are monogamous and mate for life. Pairs usually breed once every two years almost year-around, though egg-laying seems to peak from July to November.

After engaging in the breeding display, the pair starts to build a massive nest in a fork of a large forest tree, usually m ft above the ground.

While the female fetches more nesting material, the male tends to be more active in nest construction. The female lays 1 or 2 eggs usually just white, though may sometimes be overlaid with sparse red-brown markings.

Incubation lasts around 49 days done mainly by the female. The male brings food to the incubating female every 3 to 5 days.

The young hatch, covered in down, and first feathers appear in 40 days. If two eggs are laid, the younger one dies by starvation after being outcompeted for food by the older one or even directly killed by its older sibling.

After 40 days of age, the young is capable of feeding itself, though is often still fed. The young fledge at 90 to days but remains in the care of its parents for another 11 months.

It is estimated that most Crowned eagles reach breeding maturity at around five years old. Largest confirmed wingspan recorded is 1. Upperparts and head is dark in color, varying from dark grey to black sometimes with a tinge of blue.

Eyes are pale yellow to white. Feathers on legs are white with black spots, and talons and claws are large and powerful.

Tail is long and barred black and white. In flight, underwing coverts are chestnut, with the rest of the underwing white with prominent black markings.

Crowned eagles are mostly found in dense woodlands, montane forests, and rainforests. In protected areas with large open savannas, such as is common in East Africa, they are sometimes found along riverine forests and in rocky hillsides adjacent to the more open habitats and will rarely venture into the savanna.

If habitat is sufficient, they can also be found close to urban areas, especially in plantations.
