African fish eagles are majestic birds of prey that are found throughout sub-Saharan Africa, near large bodies of water such as lakes, rivers, and coastal areas. These impressive raptors are known for their distinctive call, which has been described as a loud, piercing “heeee-haw” sound. But what exactly do these birds eat, and do they consume dead animals as part of their diet?
The Diet of the African Fish Eagle
The African fish eagle is primarily a fish-eating bird, with fish making up around 90% of its diet. These birds are adept hunters, using their sharp talons and powerful beaks to capture a variety of fish species, including mullets, catfish, cichlids, tilapia, characins, and African tiger fish.
However, the African fish eagle is also an opportunistic predator, and will not hesitate to take advantage of other food sources when they are available. In addition to live fish, these birds have been known to prey on a variety of other animals, including:
- Waterbirds, such as ducks and flamingoes
- Reptiles and amphibians
- Small mammals, like monkeys and hares
- Domestic chickens
Do African Fish Eagles Eat Dead Animals?

While the African fish eagle’s primary diet consists of live fish, they are not averse to scavenging on dead animals when necessary. Immature African fish eagles, in particular, have been observed feeding on large carrion, often far from the water’s edge.
Additionally, these birds have been known to engage in a practice called kleptoparasitism, where they steal the catch of other bird species, such as large wading birds (e.g., Goliath herons, hammerkops, and shoebills), kingfishers, pelicans, ospreys, and other fish eagles. These targeted species are often hunting large fish, which can take a significant amount of time to handle, making them vulnerable to theft by the opportunistic African fish eagle.
The Importance of African Fish Eagles in Aquatic Ecosystems
African fish eagles play a crucial role in maintaining the health of aquatic ecosystems. As a tertiary predator at the top of the food chain, the population status of these birds can serve as an indicator of the overall health of the entire food web.
Ecologists, conservationists, and fish farmers can use the strength of the African fish eagle population to evaluate factors such as fish crop population, pollution in the waterways, and habitat alteration. These factors can have a significant impact on the top carnivores, like the African fish eagle, and their presence or absence can provide valuable insights into the state of the ecosystem.
Conclusion
In summary, while the African fish eagle’s primary diet consists of live fish, they are not averse to scavenging on dead animals or stealing the catch of other bird species when the opportunity arises. These opportunistic predators play a crucial role in maintaining the health of aquatic ecosystems, and their population status can serve as an important indicator of the overall well-being of the entire food web.
