The sound of the cuckoo is to many the very essence of spring, yet behind the magical call is a bird that is a cheat, a thief and a killer. Just how does the cuckoo trick other birds into accepting its eggs and raising its young? Why don't the duped foster parents react as they watch the baby cuckoo destroy their own eggs and chicks? And why do they work so relentlessly to feed a demanding chick that looks nothing like them and will soon dwarf them? In this film, new photography is combined with archive footage and the latest scientific findings to solve a puzzle which, as narrator David Attenborough explains, has perplexed nature watchers for thousands of years.
The wild dogs of Luangwa Valley are organized, tenacious and strictly hierarchical under the leadership of an alpha pair. While cheetahs sprint and lions ambush, wild dogs rely on their stamina to wear prey out, sometimes running up to 20 miles at a time. But to maintain dominance, they'll need to train their youngest members to hunt effectively as part of the pack-and time is running out.
Dolphins are one of the smartest animal species on Earth. In fact, their encephalization quotient (their brain size compared to the average for their body size) is second only to humans. But exactly how smart are they? Lori Marino details some incredible facts about dolphins.
David Attenborough's entertaining romp through the world of monkeys has a serious side: for when we look at monkeys, we can see ourselves. From memory to morality, from 'crying wolf' to politics, monkeys are our basic blueprint. Pygmy marmosets 'farm' tree sap; bearded capuchins in Brazil develop a production line for extracting palm nuts; white-faced capuchins in Costa Rica tenderly nurse the victims of battle; and in the Ethiopian highlands, a deposed gelada baboon has got the blues. Cheating, lying and bare-faced murder are all there too. These revelations of simian science, combined with captivating photography, make this film about monkey business our business.
