This special, narrated by Andrew Scott, celebrates spring on planet Earth, and the extraordinary tricks that animals and plants find to rise to the new challenges it brings. This magical season brings a burst of new life - but as soon as the air starts to warm, it's a race to wake up and get ahead of everyone else. For many, it's the perfect time to find a mate and raise babies - but for everything, from adventurous grizzly bear cubs and amorous dancing grebes, to flowers in the desert and swifts that fly marathons, spring is about rushing to make the most of the opportunities this busy season brings.

How air-breathing mammals have found remarkable ways to overcome the many challenges of a life in water, from freshwater jungle ponds to the dark depths of the open ocean. Featuring footage of the birth of a huge sperm whale calf, never-before-filmed orca hunting behaviour, and coastal coyotes in Mexico that have learnt they can benefit from the daily offerings washed up on the shore with each new tide.

This episode is devoted to the evolution of reptiles. They are not as restricted as their amphibian ancestors, since they can survive in the hottest climates. The reason is their scaly, practically watertight skin. The scales protect the body from wear and tear and in the case of some species of lizard, such as the Australian thorny devil, serve to protect from attack. The horned iguana from the West Indies is also one of the most heavily armoured. The skin is rich in pigment cells, which provide effective means of camouflage, and the chameleon is a well-known example. Temperature control is important to reptiles: they cant generate body heat internally or sweat to keep cool.

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.

The second episode of the documentary series takes a look at bizarre and extraordinary feathered dinosaurs, many of which have only just been discovered. These feathered beasts are revolutionising our understanding of life on Earth as they blur the boundaries between what we know of dinosaurs and birds. China sits at the heart of the feathered dinosaur discoveries and is the home of one of the most unusual discoveries on Earth: the epidexipteryx. Only the size of a pigeon, this predator was the most bird-like of any dinosaur and is the first known case of ornamental feathers. But feathers were not just confined to the small. From caudipteryx to sinosauropteryx and the 8-metre-long gigantoraptor, feathers may have been used for flight, for insulation or even to intimate and attract. These dinosaurs not only hint at how animals might have developed flight, but also suggest that dinosaurs may still live among us today - as birds.

In this final episode, Iolo explores bird design - from their ability to fly to the way that their beak design, colour and camouflage enable them to live in the many habitats Wales has to offer. Using ultra-slow motion photography, Iolo looks at how garden birds have such control over take off and landing, and explains why fulmars are one of our most supreme fliers.
