African fish eagles are familiar birds of prey on the waterways of sub-Saharan Africa, noted for their distinctive and 
haunting call.  These eagles perch on branches overlooking the water, swooping down to catch fish which are then 
carried back to the perch or dragged to shore if too big to carry.   African fish eagles also eat birds, monkeys and even crocodile hatchlings.  These efficient predators can get away with spending as little as 10 minutes a day actively hunting.
