Some animals have an extraordinary ability to find their way. The dung beetle, an insect revered by ancient Egyptians, uses the sun, the moon and even the Milky Way to move its prized ball of dung in the right direction. Pigeons are often considered feeble birdbrains, but they have incredible memories that can recall several complex travel routes with amazing accuracy and they even use man-made roads and hedgerows to find the quickest way home.
The islands of the Galapagos rose explosively from the ocean four million years ago. Although life would not seem viable in such a remote Pacific outpost, the first arrivals landed as the fires still burned. David Attenborough explores the islands for the animals and plants that descend from these pioneers: from the sea birds carrying the seeds that made a tentative foothold on these rocks, to equator-dwelling penguins and a dancing bird with blue feet. This is a story of treacherous journeys, life-forms that forged unlikely companionships, and surviving against all odds. It is the story of an evolutionary melting pot in which anything and everything is possible.
In this final episode we complete our journey, travelling back from the March equinox to the end of June. Kate Humble is in the Arctic at a place where spring arrives with a bang, whilst Helen Czerski chases a tornado to show how the earth's angle of tilt creates the most extreme weather on earth.
Filmed over two years in a remote part of the Canada. Cameras observe a young female grizzly as she grows into adulthood. Filmed over two years, the documentary features vistas of open plains on the Arctic Circle and frigid rivers in vast mountain ranges. Against the backdrop of the vast Yukon tundra, the climate changes from frigid winter to spring thaw with a brief sunny season in-between. The cast of characters features hulking male grizzlies, mothers and cubs socialising until the salmon runs begin. Female bears must consume enough salmon during this brief time in order to sustain the cubs that will be born during the winter.
