African Fish Eagle

The African fish eagle is a large bird, and the female, at 3.2–3.6 kg (7.1–7.9 lb) is larger than the male, at 2–2.5 kg (4.4–5.5 lb). This is typical of sexual dimorphism in birds of prey. Males usually have a wingspan of about 2 m (6.6 ft), while females have wingspans of 2.4 m (7.9 ft). The body length is 63–75 cm (25–29.5 in). The adult is very distinctive in appearance with a mostly brown body with a white head like the bald eagle and large, powerful, black wings. The head, breast, and tail of African fish eagles are snow white, with the exception of the featherless face, which is yellow. The eyes are dark brown in colour. The hook-shaped beak, ideal for a carnivorous lifestyle, is yellow with a black tip. The plumage of the juvenile is brown in colour, and the eyes are paler compared to the adult. The feet have rough soles and are equipped with powerful talons in order to enable the eagle to grasp slippery aquatic prey. While this species mainly subsists on fish, it is opportunistic and may take a wider variety of prey such as waterbirds. Its distinctive cry is, for many, evocative of the spirit or essence of Africa. 

This species is still quite common near freshwater lakes, reservoirs, and rivers, although they can sometimes be found near the coast at the mouths of rivers or lagoons. As their name implies, African fish eagles are indigenous to sub-Saharan Africa, ranging over most of continental Africa south of the Sahara Desert. Several examples of places where they may be resident include the Orange River in South Africa and Namibia, the Okavango Delta inBotswana, and Lake Malawi bordering its namesake country Malawi, Tanzania and Mozambique. The African fish eagle is thought to occur in substantial numbers around the locations of Lake Victoria and other large lakes that are found in Central Africa, particularly the Rift Valley lakes. The African fish eagle is a generalist species, requiring only open water with sufficient prey and a good perch. This is evident by the number of habitat types that this species may be found in, including grassland, swamps, marshes, tropical rainforest, fynbos and even desert bordering coastlines, such as that of Namibia. The African fish eagle is absent from arid areas with little surface water.
