The African Fish Eagle is an excellent hunter and can oft be glimpsed swerving over the water in order to dive down, catching and gripping fish with its powerful talons. Found perched high atop a tree most of the time, they survey the water, keeping a sharp eye out for its prey which includes catfish and lungfish. They will eat dead fish, but mostly live and will also eat a variety of birds such as ibis, herons and spoonbills. Breeding involves soaring, calling and claw-grappling. They can be seen in pairs during breeding season, but also out of season. Instead of building new nests every year, fish eagles will re-use old nests and just refresh them with new material. When it is close to the nest, it will give out a cry known as a "quock" and this is one of its two distinct calls, the other made when it is flying or perched. The sound of the fish eagle is so renowned that it has been hailed as "the voice of Africa".
