Two million wildebeeste, half a million thompson's gazelle and a quarter-million zebra track the changing seasons across more than 5000 square miles of savannah that is Tanzania's Serengetl National Park.
Zoologists Malcolm Coe and Robin Pellew, and wildlife film-makers Alan Root and Hugo van Lawick help celebrate its Diamond Jubilee with tales of bottom-biting leopards, hammer-chewing hyenas and a man-hunting rogue elephant.
