Yesterday : Madagascar
David Attenborough narrates the story of the island in the Indian Ocean, off the southeastern coast of Africa. It has an ecosystem that has stood in isolation for millions of years, and produced an array of wildlife that cannot be found anywhere else on the planet. He begins by observing lemurs in their habitat, male red giraffe-necked weevils fighting each other, the courting rituals of chameleons, and the behaviour of spiders and fossas.
An observation of the wildlife that inhabits the narrow band of mountains and rainforest on the island's east coast, from ring-tailed lemurs living on an inhospitable peak, to forest-dwelling sifakas, small primates on the verge of extinction. The programme also focuses on the golden bamboo lemur, which is capable of consuming daily doses of cyanide, and looks at the fruit-rich treetops where red-ruffed lemurs defend their food and territory. Narrated by David Attenborough.
