In this first episode, he investigates how and why birds communicate, looking at the reasons snipe use their tail feathers to make a very distinctive noise and what's happening when thousands of starlings participate in stunning aerial displays in Aberystwyth.
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.

With the help of some surprising creatures from around the world, this series sets out to discover how animals take to the air, defying the force all airborne animals must conquer, gravity. Part 3: Crowded Skies This episode features a creature that creates sound out of thin air with the world's fastest courtship display and arguably the world's most aggressive bird. In a South American jungle, there's 'hunt and evasion' flying during the night, as bats and moths fight for the upper hand in one of the world's oldest arms races. Plus a camera films a giant flock to unlock the secrets that keep half a million birds from colliding in the same air space.
Humans, octopi and pine trees alike are all made up of cells, tiny but sophisticated systems that keep life going. Cells are almost like tiny factories run by robots, with the nucleus, DNA, proteins, lipids, and vitamins and minerals all playing critical roles. George Zaidan and Charles Morton lay out the blueprint of a cell and explain how biochemistry binds all life together.
Visit the Bismarck Sea, a region forgotten by civilisation, where life goes on in harmony with nature as it has for thousands of years, untouched by the troubles of the modern world. You’ll dive amongst the eerie wrecks of WWII planes and ships, navigate darkness-shrouded caves and dodge swift-moving reef sharks.
Luminous beings, creatures with their own internal light, enchant and astonish us. Anyone who has seen a firefly or a glow-worm cannot help but fall under their spell. The sea at night sparkles as millions of luminous plankton reveal the shapes of dolphins in a truly magical light show. But why do animals produce living light? For centuries we could only marvel at the beauty and the mystery, but now for the first time we can begin to reveal the amazing truth about living lights. It has taken three crucial technological breakthroughs. Firstly, colour cameras have improved dramatically; they are now over 4,000 times more sensitive than a decade ago. The cameras are so sensitive they are revealing startling discoveries that until now we could not see. Secondly, scientists have entered the unknown world of the boundless deep open ocean with the help of a new generation of submersibles and robots. Thirdly, Ammonite Films have invented and built a series of unique cameras that can capture the faintest ephemeral glow of luminous life. By combining these three innovations, this film shows creatures and behaviours never seen before. Sir David Attenborough is our guide as we venture into a new hitherto unseen world. Bioluminescence is everywhere: in the soil, on the land and throughout the oceans. Join Sir David Attenborough and a team of the world's leading scientists and deep sea explorers on a quest to reveal the secrets of living lights.
