In the last 30 years the world's urban areas have almost tripled in size, changing at a rate wildlife has never experienced before. As cities are built, animals are pushed out of their natural homes. Their stories are the most surprising and captivating of all. Today, these 'wild outcasts' find themselves fighting for their place in a land that once belonged to them. In this episode we feature elephants in Sri Lanka and see that competition between them and humans for land and resources is resulting in deadly territorial conflicts, which demand solutions. And on the Pacific coast of Costa Rica we meet a troop of capuchin monkeys and learn how our behaviour is affecting them, and raising big questions about their future. But we also discover where we learn to live with wildlife as neighbours, and give it the space and resources it needs, it can thrive. The resulting relationships between human and animals can be mutually beneficial. We meet an Amsterdam heron called Kiri who has been visiting the same house twice a day for the last 17 years, befriending its owner, and the Florida manatees whose population has recovered to such an extent under the guardianship of local human residents that, in recent years, they have been taken off the endangered species list, and contributed to a massive boom in the local tourism industry. We meet the swiftlets who have evolved to live only in people's houses and specially built swiftlet hotels in Indonesia. And the surprising story of a population of tiny foxes on a Californian island whose presence benefits the hardened military personnel of a US naval base. This hopeful but realistic episode culminates with the return of charismatic ocean giants to the world's most iconic city, as humpback whales breach against the New York skyline.

The third episode looks at the last generation of killer dinosaurs - carnivores that took killing to a new level. By the end of the cretaceous period - 75 millions years ago - these gigantic and specialised hunter-killers had spread throughout the globe. In the southern continents it was the powerful and muscular abelisaurids that reigned supreme but it was the famous tyrannosaurids (or tyrant dinosaurs) that dominated in the north. Whilst the northern daspletosaurus hunted in gangs, using its highly developed smell and hearing to take down opponents like the horned rhino-sized beast, chasmosaurus, in the Southern hemisphere the small-skulled majungasaurus reigned. And though the sharp toothed majungasaurus was an efficient killer of the much smaller feathered rahonavis that did not stop it from occasionally turning cannibal and hunting its own.

The series starts in North Africa, where two of the world's biggest predators once battled for supremacy. At 13m and seven tonnes, the carcharodontosaurus was a huge beast, a gigantic lizard-like carnivore with shark-like teeth over six inches long. It was an efficient hunter that would slash at its prey until it bled to death. But the discovery of an upper jaw in Morocco revealed an even bigger carnivorous killer - spinosaurus. Four metres longer than Tyrannosaurus rex, spinosaurus is thought to have been one of the biggest killers to ever walk the Earth. But unlike the meat-eating carcharodontosaurus, spinosaurus mainly ate fish, living and hunting almost exclusively in the water. Like all predators that share an environment, the two may once have had to compete for food. Planet Dinosaur takes a look at what one such deadly battle may have looked like and finds out which giant beast would have been most likely to survive a fight to the death.

In nature, living long enough to breed is a monumental struggle. Many animals and plants go to extremes to give themselves a chance. Uniquely, three brother cheetahs band together to bring down a huge ostrich. Aerial photography reveals how bottle-nosed dolphins trap fish in a ring of mud, and time-lapse cameras show how the Venus flytrap ensnares insect victims. The strawberry frog carries a tadpole high into a tree and drops it in a water-filled bromeliad. The frog must climb back from the ground every day to feed it. Fledgling chinstrap penguins undertake a heroic and tragic journey through the broken ice to get out to sea. Many can barely swim and the formidable leopard seal lies in wait.

The Negev Desert in Israel is one of the world's most extreme arid lands. Surprisingly, wolves live here. They're called Arabian wolves and their global population is estimated at a mere 700. For the first time ever, a crew was able to film them for an extended period. Some of the scenes captured include parents raising cubs in their dens and epic battles against their worst enemies. With unique and exceptional footage, viewers will discover the amazing lives of these mysterious wolves.
