Overview:Hyenas are loathed and feared by many people. Wildlife cameraman Gordon Buchanan journeys across Ethiopia to find out how the people here can live so close to these powerful carnivores. Ethiopia has more hyenas than anywhere else in the world, and Gordon wants to find out why. He starts his journey in the capital, Addis Ababa. Even here on the outskirts of this massive city, spotted hyenas prowl looking for food. Local hyena expert Girum Henok takes Gordon on foot to see hyenas at night in a small patch of forest. Weighing up to 90 kilos and capable of killing lions in packs, hyenas are one of Africa's most impressive carnivores. Girum tells Gordon that hyenas are tolerated here because people believe hyenas ward off the devil.
