African fish eagle is a large bird, and the female, at 3.2-3.6 kg is larger than the male, at 2-2.5 kg. This is typical of sexual dimorphism in birds of prey. Males usually have a wingspan of about 2 m, while females have wingspans of 2.4 m. The body length is 63–75 cm. 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.

African jacanas are conspicuous and unmistakable birds. They are about 30 cm long, but females are larger than males. They have chestnut upperparts with black wingtips, rear neck, and eyestripe. The underparts are also chestnut in the adults, only in juveniles they are white with a chestnut belly patch. The blue bill extends up as a coot-like head shield, and the legs and long toes are grey.
