Overview
The haunting call of the African fish eagle echoing across the water is one of the most recognisable sounds of the continent. Often described as the “Voice of Africa”, this striking bird of prey is commonly found beside Tanzania’s lakes, rivers and wetlands, where it watches the water from a high branch before launching into flight.
Adult fish eagles are unmistakable, with a brilliant white head, neck, chest and tail, a rich chestnut body and broad black wings. Their powerful feet and curved talons are adapted for grasping slippery prey, allowing them to sweep low over the surface and lift fish from the water.
Fish make up most of their diet, but these adaptable hunters also take waterbirds, reptiles and other small animals. They readily scavenge and may steal catches from herons, storks and other fishing birds—a behaviour known as kleptoparasitism.
Behaviour & How to Identify
Look for a large eagle with broad wings, a short white tail and a sharply hooked black-and-yellow bill. Adults have a white head and chest that contrast strongly with their chestnut body and dark wings. Juveniles are mostly mottled brown and do not develop their full adult colouring until several years of age.
African fish eagles spend long periods perched beside the water, scanning for movement below. When a fish approaches the surface, the eagle swoops down feet first and grips it with powerful talons. Small catches may be carried away, while heavier fish are sometimes dragged towards the shore.
Pairs usually occupy territories centred around productive stretches of water. Their loud, far-carrying calls help advertise ownership and allow the pair to remain in contact. They often call together, throwing their heads backwards as the sound carries across the surrounding landscape.
Interesting facts
African fish eagles are usually seen in established pairs. They form long-lasting bonds and may remain within the same waterside territory for many years.
Their nests become larger with repeated use. Built mainly from sticks in tall trees near water, a regularly reused nest may eventually reach around two metres across.
Their feet are specially adapted for catching fish. Rough structures on the soles, known as spicules, help the eagle maintain its grip on wet, slippery prey.
