The wetland paradise of the Okavango in Botswana is a rich feeding ground for a spectacular array offish predators, including the magnificent fishing owl. By day, eagles and kingfishers also plunder the waters, while below the surface lurk other bizarre hunters. But by night the fishing owl rules supreme.

Narrated by David Attenborough, this documentary captures the hunting prowess of this rare bird in action as it plunges into the dark waters to seize the pike that live there.
