One of the world’s happiest, yet most vulnerable marsupials, the Quokka thrives only on Rottnest Island. In almost plague proportions over ten thousand of the strange relic wallabies live here. How do they survive here in such inhospitable conditions and nowhere else?
This episode describes the migration of most animals northwards (some from the Antarctic continent, others from the few islands surrounding it) as the continent and surrounding sea freeze over at the end of summer. It shows how young penguins often fall prey to Leopard Seals as they try to make their way across the already partially frozen water and how their stripped remains become food for isopods and meter-long nemerteans (ribbon worms). Before going to the sea, however, the adult penguins must shed their coats (molting).

David Attenborough is in the Swiss Jura Mountains to discover the secrets of a giant. Beneath his feet lies a vast network of tunnels and chambers, home to a huge empire of ants. It is believed to be one of the largest animal societies in the world, where over a billion ants from rival colonies live in peace. Their harmonious existence breaks many of the rules for both ants and evolution, and raises some important questions. Through winter, spring and into summer, David turns detective to find the answers.

David Attenborough has a passion for birds' eggs. These remarkable structures nurture new life, protecting it from the outside world at the same time as allowing it to breathe. They are strong enough to withstand the full weight of an incubating parent and weak enough to allow a chick to break free. But how is an egg made? Why are they the shape they are? And perhaps most importantly, why lay an egg at all? Piece by piece, from creation to hatching, David reveals the wonder behind these miracles of nature.
