Two million wildebeest, half-a-million Thompson's gazelles and a quarter-of-a-million zebras track the changing seasons across more than 5,000 square miles of Savannah that is Tanzania's
Serengeti 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.
