David Attenborough investigates two shells that have proved to be winners in evolution: the tortoise's shell and the shells of birds' eggs. The ostrich egg is so strong it is possible for a person to stand on it without it breaking, but how does the chick break out of this fortress? The evolution of the tortoise shell was for a long time a mystery and this bony box offers a lot more than just protection.

This episode takes flight across North America, as a flock of millions of snow geese discover what it is like to be on the hit list of America's national bird: the bald eagle. In California, pelicans reveal devil rays that perform astonishing somersaults and find bizarre grunion fish that wriggle ashore to spawn. In Alaska, bald eagles swoop among brown bears fishing for salmon. And on the Great Plains, cowbirds duck and dive under the feet of fighting bison.

Chris looks at social intelligence in the animal kingdom and finds out why it is that, for animals, being together means being clever. He looks at how lions hunt in teams and each hold a very specific position, how vampire bats build trust and donor networks through grooming, and how wild wolves first became domesticated and transformed into man's best friend.

David Attenborough reveals that the animal inhabitants of this vast wilderness are every bit as extraordinary as they are bizarre. Unearthly calls of the notorious Tasmanian devil echo through the land, but following them over the course of a year reveals a surprisingly gentle side. In the dry east, rare white wallabies graze on the plains and jack jumper ants build huge nests – these venomous ants are amongst the most dangerous on earth. In the west, where it can rain nearly every day of the year, caves light up with the magical spectacle of thousands of glow-worms, and the trees are 100-metre towering monsters. Rivers are home to the peculiar platypus, and world’s largest freshwater invertebrate, the Tasmanian giant lobster. Miniature penguins come ashore to breed, and as winter approaches, the southern lights dance in the sky. Tasmania’s isolation and unique climate has created a world that is as weird as it is wonderful.
