Although it is slightly similar, that was the call of a Martial
Eagle. The African Fish Eagle has two distinct calls. In flight or perched,
the sound is similar to that of the American Bald Eagle. When near the nest,
its call is more of a 'quock' sound. The call of the female is a little
shriller and less mellow than the male. The call of this bird is commonly
heard and is known as 'the voice of Africa'.
