Cities: Nature's New Wild

The world's cities are growing at a faster rate than any other habitat on the planet. And while most of us imagine them to be concrete jungles devoid of nature, for animals of all shapes and sizes they are just a new habitat filled with new and surprising opportunity.

This episode explores whether the secret to an animal's success in this fast-changing world is to keep one foot in the wild and one in the city, becoming a wild commuter. Leaving the wilderness they must overcome the unique challenges that the urban world throws at them to benefit from the opportunities on offer.

As cities are built, animals are pushed out of their natural homes. 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, a troop of capuchin on the Pacific coast of Costa Rica, an Amsterdam heron called Kiri, Florida manatees.
