Not a very photogenic species today but a very important one ecologically. The African White-backed Vulture (Gyps africanus)

The white-backed vulture (Gyps africanus) is an Old World vulture in the family Accipitridae, which also includes eagles, kites, buzzards and hawks. It is closely related to the European griffon vulture, G. fulvus. Sometimes it is called African white-backed vulture to distinguish it from the Oriental white-backed vulture—nowadays usually called white-rumped vulture—to which it was formerly believed to be closely related.

The white-backed vulture is a typical vulture, with only down feathers on the head and neck, very broad wings and short tail feathers. It has a white neck ruff. The adult’s whitish back contrasts with the otherwise dark plumage. Juveniles are largely dark. This is a medium-sized vulture; its body mass is 4.2 to 7.2 kilograms (9.3–15.9 lb), it is 78 to 98 cm (31 to 39 in) long and has a 1.96 to 2.25 m (6 to 7 ft) wingspan.

Like other vultures it is a scavenger, feeding mostly from carcasses of animals which it finds by soaring over savannah. It also takes scraps from human habitations. It often moves in flocks. It breeds in trees on the savannah of west and east Africa, laying one egg. The population is mostly resident.

As it is rarer than previously believed, its conservation status was reassessed from Least Concern to Near Threatened in the 2007 IUCN Red List.[5] In 2012 it was further uplisted to Endangered. In 2013 it is further uplisted to Critically Endangered.

The African Fish Eagle (Haliaeetus vocifer). It is the national bird of Zimbabwe and Zambia.

The African fish eagle (Haliaeetus vocifer) or – to distinguish it from the true fish eagles (Ichthyophaga), the African sea eagle – is a large species of eagle that is found throughout sub-Saharan Africa wherever large bodies of open water occur that have an abundant food supply. It is the national bird of Zimbabwe, Zambia and South Sudan. As a result of its large range, it is known in many languages. Examples of names include: Visarend in Afrikaans; Aigle Pêcheur in French; Hungwe in Shona, and Inkwazi in isiZulu.

The African fish eagle is a large bird, and the female, at 3.2-3.6 kg (7-8 lbs) is larger than the male, at 2-2.5 kg (4.4-5.5 lbs). This is typical of sexual dimorphism in birds of prey. Males usually have a wingspan of about 2 m (6 feet), while females have wingspans of 2.4 m (8 feet). The body length is 63–75 cm (25–30 in). The adult is very distinctive in appearance with a mostly brown body 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. The call, shriller when uttered by males, is a weee-ah, hyo-hyo or a heee-ah, heeah-heeah.
