In the northeast corner of Botswana, the rainy season is months away. The sausage tree offers a beguiling oasis for wildlife--from birds and insects, to much larger mammals like elephants--all reeling from the dry conditions. Then, as the rains descend, brilliant red flowers bloom and entice parrots, squirrels, and sunbirds to help with pollination. Summer allows the sausage tree to live up to its name, delivering massive, sausage-shaped fruit, a nutritious feast and a cornerstone of life in this exotic ecosystem.
South America - the most species rich continent on Earth. From the volcanoes of the Andes to the world’s largest rainforest, the Amazon, animals here must specialise to carve out a niche. In Patagonia, a puma mother draws on a lifetime’s experience to catch prey three times her weight. In the cloud forest, rarely seen Andean bears clamber thirty metres into the canopy to find elusive fruit. Poison dart frogs use ingenious methods to keep their tadpoles safe, whilst anacondas stalk capuchin monkeys. At Igauzu, swifts make death-defying flights through one of the biggest waterfalls on Earth.
New England is the stage for the most incredible colour change on earth, when the vivid greens of summer give way to the gold’s and reds of autumn. This film reveals how this vibrant fiesta is created by the battles between the trees and the forests' inhabitants. Moose, chipmunks, rattlesnakes and a bizarre mixture of caterpillars all play a crucial role, but surprisingly the forest itself was made so colourful thanks to a combination of hard work by beavers, ants and humans.
