African Crowned Eagle - Stephanoaetus coronatus

Scientific classification
Kingdom: Animalia
Phylum: Chordata
Class: Aves
Order: Falconiformes (or Accipitriformes, q.v.)
Family: Accipitridae
Genus: Stephanoaetus
Species: Stephanoaetus coronatus

The Crowned Eagle (Stephanoaetus coronatus), more precisely known as the Crowned Hawk-eagle, is a very large, powerful, crested bird of prey (80-90 cm approx) found in tropical Africa south of the Sahara; in Southern Africa a common resident in suitable habitat in the eastern areas.

It inhabits mainly dense forests; its staple diet consists of monkeys (particularly those of the genus Chlorocebus) and other mammals up to 20 kg (44 lb), such as the Cape Hyrax and small antelopes. To a far lesser extent, birds and monitor lizards are also taken, however 98% of the diet is mammalian.

While smaller than the Martial Eagle, the Crowned Eagle is renowned as Africa's most powerful and ferocious eagle in terms of the weight and nature of prey taken. Due to their striking similarities, the Crowned Eagle is often considered Africa's analogue of the Harpy Eagle.

The Crowned Hawk-eagle is the only extant member of the genus Stephanoaetus. A second species, the Madagascar Crowned Hawk-eagle (Stephanoaetus mahery) became extinct after humans settled on Madagascar (Goodman, 1994). It was the largest and strongest bird of prey of prehistoric Madagascar (see Elephant Bird) and together with the living Fossa (animal) Cryptoprocta ferox, the larger Giant Fossa Cryptoprocta spelea (Goodman et al. 2004) and the two malagasy crocodiles, the living Nile crocodile and the recently extinct giant dwarf crocodile Crocodylus robustus the apex predators on the island. Extinction by overhunting of the giant lemurs which constituted its main prey seems to have been the main reason for this species' disappearance, which took place at some time during the second half of the first millennium AD.

African Crowned Eagle Conservation - Simon Thomsett

Size :
The Crowned Eagle is Africa’s largest forest eagle that shares much of its biology with the world’s other great forest eagles such as the Philippine and Harpy Eagles. It weighs between 5.5 and 11 pounds and has feet as large as a man’s hand with needle sharp hind talons.

Prey Size : On average, it captures the largest prey of any eagle. Both in Kenya and in West Africa it has the propensity to take the very largest of male monkeys feeding on the troop periphery. These 15 to 35-pound sentinels are formidable and immensely strong. Other favored prey items are usually within their own weight but on occasion they are capable of taking antelope up to the size of a full grown female bushbuck weighing around 90 pounds (40 kg). It competes directly with the larger mammalian carnivores
