In this episode, Iolo investigates the courtship and nesting behaviour of birds, including the amazing courtship display of great crested grebes at a reservoir near Pontypool, the impressive sky dance of hen harriers in the dramatic Cambrian Mountains, how nuthatch use mud like cement to prepare their nest in a woodland near Harlech, and why long-tailed tits near Newtown are exceptional nest builders. On the Lleyn Peninsula near Trefor, he looks at why one colony of shags nest earlier than any others in Wales, and in Pembrokeshire he finds out where house martins nested before they used our buildings. Iolo also looks at the variety of places birds like to nest, from little ringed plovers on shingle banks along the River Tywi to puffins underground on Skomer.

In this fourth episode, Iolo Williams explores how birds in Wales have adapted to living alongside us, making use of our buildings, parks and gardens and even the waste we throw away. One of the most notorious urban birds is the gull and Iolo explains why these very adaptable and intelligent birds are doing so well in Cardiff

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.

How can you tell the two poles apart? Where are the penguins? What about the bears? The Arctic pole is located in the Northern Hemisphere within the deep Arctic Ocean, while the Antarctic pole is smack in the middle of the ice-covered Antarctica. Camille Seaman describes how enterprising people and organisms have found ways to reside around both poles despite the frigid temperatures.
Investigates the greatest vanishing act in the history of our planet - the sudden disappearance of the dinosaurs 66 million years ago. Experts suspect that the dinosaurs were wiped out after a city-sized asteroid smashed into the Gulf of Mexico causing a huge crater. But until now, they haven't had any proof. In a world first, evolutionary biologist Ben Garrod joins a multi-million pound drilling expedition into the exact spot the asteroid hit to get hard evidence of the link. The team overcomes huge obstacles as it attempts to drill 1,500 metres beneath sea level to pull up rock from the Chicxulub crater.

Documentary series delving into a rarely seen South American wilderness, home to surprising creatures who survive in environments that range from the mighty Andes Mountains to Cape Horn. Part 3: Life on the Edge This is the story of an awe-inspiring coastline, 4000 miles long. From the cold, fearsome waters of Cape Horn, where brave rockhopper penguins overcome huge challenges to raise their young, to the far north, with huge elephant seals battling for position in the heat of the desert. Orcas ram-raid the beaches, grabbing seal pups to feed their young. People too gather the sea's bounty, but these shores are not for the faint-hearted.
Every year, spectacular seasons transform our planet. As they sweep across the world, they drive all life on earth, bringing huge opportunities and great challenges to everything. 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.
David Attenborough returns in this landmark series to his most magical place on earth exploring the Great Barrier Reef aboard the research vessel Alucia. Part 1: Builders David descends beneath the waves at night in the state-of-the-art Triton submersible, the first of its kind to visit the reef. He meets some of the tiny coral animals that built the reef and helped to turn it into an underwater wonderland. He then takes to the skies to witness the vast scale of their endeavour, a living structure that provides a home for thousands of species. Using cutting-edge technology to generate computer scans of the sea floor, David learns that the Great Barrier Reef we know today is much younger than scientists ever imagined. He meets some of the people that have lived alongside it and who have told stories of its origins for thousands of years.
