African Crowned Eagle - Stephanoaetus coronatus
The Crowned Eagle, also known as the African Crowned Eagle or the Crowned Hawk-eagle (Stephanoaetus coronatus) is a very large, powerful, crested bird of prey found in sub-Saharan Africa; in Southern Africa it is restricted to suitable habitat in the eastern areas. It is the only extant member of the genus Stephanoaetus. A second species, the Malagasy Crowned Eagle (Stephanoaetus mahery) became extinct after humans settled on Madagascar. It mainly inhabits dense forests. Its staple diet consists of monkeys (particularly those of the genus Chlorocebus) and other medium-sized mammals, such as the Cape Hyrax and small antelopes. To a far lesser extent, birds and large lizards are also taken. However, at least 90% of the diet is mammalian. While on average smaller in all measurements but length than the Martial Eagle, the Crowned Eagle is often considered Africa's most powerful and ferocious eagle in terms of the weight and nature of prey taken. It often preys on mammals such as duikers, weighing up to 30 kg (66 lb). The female, at a weight of 3.2–4.7 kg (7 lb 1 oz–10 lb 6 oz), is around 10–15% larger than the male, at a weight of 2.55–4.12 kg (5 lb 10 oz–9 lb 1 oz). An average body mass of 3.64 kg (8.0 lb) was given in one account. Elsewhere, an average of 3.8 kg (8.4 lb) has been claimed. Overall, they are the 9th heaviest living eagle species. This eagle has relatively short, broad and rounded wings, with the wing chord measuring 44.5–53.2 cm (17.5–20.9 in) for added manoeuvrability in its environment. The tarsus is of moderate length for a raptor of its size, at 8.5–10.3 cm (3.3–4.1 in), but the talons are heavy, strong and powerful.
Golden Eagle - Aquila chrysaetos
The Golden Eagle (Aquila chrysaetos) is one of the best known birds of prey in the Northern Hemisphere. Like all eagles, it belongs to the family Accipitridae. Once widespread across the Holarctic, it has disappeared from many of the more heavily populated areas. Despite being extirpated from some its former range or uncommon, the species is still fairly ubiquitous, being present in Eurasia, North America, and parts of Africa. The highest density of nesting Golden Eagles in the world lies in southern Alameda County, California. These birds are dark brown, with lighter golden-brown plumage on their heads and necks. The Golden Eagle is a large, dark brown raptor with broad wings. Its size is variable: it ranges from 66 to 100 cm (26 to 39 in) in length and it has a typical wingspan of 1.8 to 2.34 m (5.9 to 7.7 ft). In the largest race (A. c. daphanea) males and females weigh 4.05 kg (8.9 lb) and 6.35 kg (14.0 lb). In the smallest subspecies (A. c. japonensis), the sexes weigh, respectively, 2.5 kg (5.5 lb) and 3.25 kg (7.2 lb). The maximum size of this species is a matter of some debate, although the normal upper weight limit for a large female is around 6.8 kg (15 lb) and large races are the heaviest representatives of the Aquila genus.
