A unique celebration of one of Earth's most iconic birds. For the first time, we meet the entire penguin family - all 18 species. This colourful cast of characters may seem familiar, but their incredible diversity won't fail to surprise. New Zealand's lush green forests might not be the first place you would expect to find penguins, but it was here the penguin family first evolved 60 million years ago, and there are now more species living here than anywhere else on earth. One quirky-looking resident is the Snares penguin, which likes nothing more than a spa treatment. In Cape Town, the African penguin has adapted to the modern world, strolling the city streets with all the other commuters. And, against all the odds, one of the smallest members in the family, the Galapagos penguin, has found a way to survive the sweltering heat of the equator. One of the biggest secrets to the penguin success story is their remarkable parenting skills. Adelie penguins perform the longest penguin migration on earth, over 6,000 miles, to find the perfect nesting site. Ninety-nine per cent of them return to the same nests each year, but after a hard winter their stone nests need some serious renovation. Other species are sneakier, stealing their neighbours stones the moment they turn their backs. The fastest penguin on the planet is the gentoo, reaching speeds of 22mph and diving to 200 metres. Short feet that act like rudders and a streamlined body allows them to shoot through the water, while fused muscular wings act like paddles. Penguins are supremely adapted to an aquatic life, spending 75 per cent of their lives in water, but all penguins have to walk at some point, so to get around they have developed the infamous waddle. This bizarre locomotion may look inefficient, but surprisingly it actually works in their favour. Whilst we get 65 per cent of the energy back with each step, penguins can get up to 80 per cent, so the waddle is more efficient that our own walk. Over millions of years, penguins have mastered life on land and in the sea, but we are now changing the planet faster than ever before, and some penguins are struggling to keep up, so technology is being used to locate and observe new colonies from the equator to Antarctica. This is the family penguin as you have never seen them before.

As a boy, frogs were the first animals Sir David Attenborough kept and today he is still just as passionate about them. Through his eyes, the weird and wonderful world of frogs is explored, shedding new light on these charismatic, colourful and frequently bizarre creatures. David reveals all aspects of the frogs' life, their anatomy, their extraordinary behaviour and their ability to live in some of the most extreme places on the planet, as he goes on an eye-opening journey into the fabulous lives of frogs.

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.

The final programme looks at the superorganisms formed by bees, ants and termites. Attenborough reveals that their colonies, whose individuals were once considered purely servile, are "full of conflict, power struggles and mutinies." They evolved when such creatures moved away from a solitary existence and started building nests side-by-side, which led to a collective approach to caring for their young.

Liz Bonnin introduces a cast of charismatic animals to reveal the remarkable strategies they use to survive, and even thrive, in winter. For animals this is the toughest time of year, and preparations start early. In autumn, Siberian chipmunks collect food in their cheek pouches to stockpile in their burrows, while caribou make an epic journey to new feeding areas away from the worst weather. With the arrival of winter, the American bobcat has to find its prey beneath deep snow, while an Arctic fox must sniff out its very own frozen ready meal. A sea otter mum keeps her cub warm by blowing air into its coat, while some animals turn white to blend in with the snowy world around them. As winter begins to loosen its grip, an Arctic ground squirrel stirs from an eight-month hibernation and has to woo its mate in just twelve hours, and baby animals emerge to play in the snow before spring's imminent arrival. Along the way, Liz meets some of our most iconic winter animals to uncover the secrets behind their seasonal success stories.
