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.
David Attenborough chooses his ten favourite animals that he would most like to save from extinction. From the weird to the wonderful, he picks fabulous and unusual creatures that he would like to put in his 'ark', including unexpected and little-known animals such as the olm, the solenodon and the quoll. He shows why they are so important and shares the ingenious work of biologists across the world who are helping to keep them alive.
A look across Hawaii's varied islands, discovering how they were made, and how its wildlife thrives. The most remote island chain on Earth, its tropical shores are hard to reach. However, for the hardy creatures that have made it there, such as the waterfall-climbing fish, carnivorous caterpillar and Laysan albatross, a land of opportunity awaits. From newly formed lava fields, to lush jungles, and vibrant coral reefs, these diverse and beautiful islands have it all. As this documentary reveals, its people are looking to the future and attempting to protect and foster its flora and fauna.
The members of the Nsefu pride take a huge risk: they're leaving their home turf, and crossing the Luangwa River in search of prey. Navigating croc-infested waters is a challenge, especially for the pride's yearling, dubbed the Misfit. It's a foolhardy gamble, but hunger has forced their hand. If they're to succeed, they'll need the Misfit to come of age-their very survival depends on it.
The Okavango Delta is one of the world's largest inland deltas - and supports a variety of life as rich as any you will see in Africa. Yet this lush wetland of islands and lagoons lies in the middle of the vast, featureless Kalahari Desert. This is the story of how it happens. Following groups of wildlife, including hippos, baboons, catfish, kingfishers, leopards, warthogs and elephants, the film reveals how the yearly flood transforms the landscape and impacts their lives. But more surprisingly, it reveals how, with the help of termites and hippos, the flood actually creates this extraordinary delta in the first place.
