African Fish-Eagle
African Fish-Eagle
Haliaeetus vocifer
Introduction: African fish-eagles (Haliaeetus vocifer) are usually associated with large water bodies including estuaries, but are known to hang around dry rivers until pools have dried up in search of the food. This could including hunting Etosha National Park's only fish, the sharptooth catfish (Clarias gariepinus) . The African Fish Eagle is the official bird of Namibia, appearing on the countries coat of arms.
African fish eagles can be observed in pairs, perched on large waterside trees on the lookout for prey. Roosts near water, in cliffs or in tall trees. A characteristic of the African fish-eagle is their aggressive territorial behaviour (vocifer is Latin for vociferous) when 2 birds will catch each other by the feet and cartwheel down, only parting just before they hit the water.
