Some animals give their young the best start in life by making truly astonishing journeys. And it's not only where they go that's important but when. Left to fend for themselves until they find their footing, baby sea turtles, elephant seal pups, pumas and crabs bravely trek towards adolescence.

The seventh episode of the series takes us on an epic journey to discover the extraordinary dynasty of mammals. From their humble origins in the Jurassic forests to their dominance in the modern world, mammals have evolved and survived through cataclysmic events and drastic environmental changes. From the small coati in the jungle to the majestic Megacerops, passing through the elusive snow leopard in the Himalayas and the gigantic marine mammals like whales, the documentary illustrates the adaptability and diversity of these incredible beings.
With stunning images and masterful narration, the documentary is a window to the resilience and beauty of life on Earth, celebrating the tenacity and ingenuity of mammals throughout the ages.

Extraordinary. Dramatic. Beautiful. The series exposes the wonders of British wildlife. It's our home, as you've never seen it before. David Attenborough celebrates Britain's wildlife that is as dramatic and spectacular as any he's seen abroad and reveals why it is globally important for nature.
In this special documentary commissioned by the RSPB, WWF and National Trust and inspired by Wild Isles, we meet passionate people trying to restore nature to the British Isles.

In the first episode, Sir David Attenborough reveals the unexpected wildlife riches of the British Isles, showcasing the dramatic and spectacular habitats that rival any across the globe. This journey uncovers the diversity of life in the UK's unique landscapes, from the intricate world of bumblebees to the swift lives of kingfishers. The episode captures extraordinary scenes of nature, including killer whales preying on seals, golden eagles in the Scottish mountains, the cunning tactics of woodland plants, and the perilous life of puffins evading gulls. It highlights Britain's geological diversity as a cornerstone of its natural wealth, contributing to an array of habitats and supporting a wide range of life.
Britain's importance extends to being a haven for migratory birds, with our seas feeding 65% of the world's gannets and supporting the largest colony of northern gannets on Scotland's Bass Rock. The west coast of Scotland offers sanctuary to barnacle geese due to its abundant food and mild climate, though they remain vigilant against hunting sea eagles. Despite these natural treasures, Britain faces challenges as one of the most nature-depleted countries globally. Sir David Attenborough emphasizes the need to conserve and restore these wild isles for the enjoyment and benefit of future generations.

Sir David Attenborough explores the incredible diversity of Britain’s woodlands, taking us on a seasonal journey through our forests, and revealing a host of spectacular animals and the hidden dramas that rule their lives.
In an ancient pine tree in the Cairngorms, two eagle chicks are on the verge of fledging their gargantuan nest. In winter in the Forest of Dean, the reintroduction of wild boar has given the robin a lifeline. As they root through the thick snow, the boar unearth the worms with their snouts, which the robins otherwise couldn't find.
Back in Scotland, a male capercaillie displays to gathering females. These birds are on the edge. With only around 500 left, they are some of the rarest and most threatened in the British Isles. In a beech woodland outside London, the deciduous trees burst to life in spring, and huge colonies of wood ants awaken and go looking for food. Also looking for sustenance is a female roe deer. With no large predators left in our woods, the deer are free to browse on new growth to the extent that they can damage the woodland itself.
In Sussex is an ancient-looking landscape, but one that has only been recreated in the past 20 years. This is the wood pasture of Knepp, created by using old grazing methods that generate a mix of scrub, open areas and ancient trees. In the Scottish Highlands, red squirrels battle it out for access to ripe pine cones at the top of a tree. It’s an acrobatic and energetic encounter, with more than a little cunning required to win the day. As the summer finally fades, we encounter a honey buzzard nest, where two chicks feast on wasp grubs, squabble between themselves and grow up before our eyes.
Autumn brings the fallow deer rut. The woods resonate with their calls, and bucks fight for supremacy. The season also brings colour, both in the leaves but also in the fungi that fruit at this time of year. The mushrooms are just a tiny part of their story, however, and we travel underground to see how the wood-wide web connects the whole forest together.

Mountains create frozen habitats on every continent on Earth, and each of these high-altitude worlds holds unique challenges for its surprising and remarkable life.
We begin our journey close to the equator - the furthest point from the poles - in East Africa. Here on the high slopes of Mount Kenya, during the day the tropical sun keeps the cold at bay, but at night the frost descends. During this cycle of freeze and thaw, a pregnant high-casqued chameleon must choose the right time to give birth if her newborns are to escape the deadly night freeze.
Away from the equator in the European Alps, long cold winters give way to short, bountiful summers. For a pair of golden eagles raising their chick, the demand to provide enough food for it drives them to tackle prey five times their size. To catch a goat-like chamois, they risk it all using one of the most daring and breathtaking hunting techniques ever witnessed.
The mountains of Japan are the snowiest place on Earth, providing hostile conditions for a lone male macaque cast away from his troop. His only chance of survival comes with finding another male whose embrace will provide him with life-saving warmth. But in the frozen peaks, the deadliest force is an avalanche whose full destructive power is captured for the first time using high-speed camera racer drones.
The roof of the world is home to an array of unexpected cold-loving creatures. In the remote Southern Alps of New Zealand, a species of parrot - the kea - uses its famed intelligence to feed on the dead. And in the Andes in South America, flamingos thrive in high-altitude volcanic lakes, but their chicks must race to escape the winter freeze or risk becoming trapped in the ice.
Today, due to climate change, our frozen peaks are undergoing rapid change. Using groundbreaking time-lapse photography, we reveal mountain glaciers vanishing before our very eyes and discover what a warming world may mean for our most famous mountain resident of all, the giant panda.
