As temperatures hit minus 60 food becomes scarce, and animals such as foxes and hares shed their colourful coats to camouflage themselves in the snow. The end of winter heralds one of the world's greatest feeding frenzies as large ocean predators target the millions of fish who have found refuge in the Gulf of Alaska.

Our planet was once populated by megafauna, big top-of-the-food-chain predators that played their part in balancing our ecosystems. When those megafauna disappear, the result is a "trophic cascade," where every part of the ecosystem reacts to the loss. How can we stay in balance? George Monbiot suggests rewilding: putting wolves, lions and other predators back on top -- with surprising results.

This film is a unique production that reveals the beauty of Romania as it is, raw, magical but fragile at the same time. In the heart of Europe, there is a fabulous wildlife, rich in biodiversity, home to numerous wild animals. The endless mountain peaks and river streams, ancient forests, all provide home to various creatures. Their lives are dictated by the seasons of these lands of beauty. It's a never ending battle for survival and Untamed Romania will tell their stories. Who will survive the trials of life in this ever changing environment?

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.

A humpback whale mother and calf embark on an epic journey from tropical coral paradises to storm ravaged polar seas. Newly discovered coral reefs in Indonesia reveal head-butting pygmy seahorses, flashing 'electric' clams and bands of sea kraits, 30-strong, which hunt in packs. Elsewhere plagues of sea urchins fell forests of giant kelp. Huge bull fur seals attack king penguins, who despite their weight disadvantage, put up a spirited defence.
