In this episode, Chris reveals how the world's most spectacular grasslands flourish, despite being short of one essential nutrient - nitrogen. As it turns out, the secret lies with the animals. There are the white rhinos of Kenya that create nitrogen hotspots by trimming and fertilising the grass. They are drawn to these particular points by communal toilets or 'fecal facebooks', where they meet and greet each other. In the whistling acacia grasslands of Kenya, Chris reveals the amazing relationships between termites, geckos, ants, monkeys and giraffes that make these places so rich in wildlife

Liz meets the animal rebels who will stop at nothing to survive. From cockatoos vandalising houses in Sydney, to crabs who hold nemones hostage to protect themselves, it seems there are no lengths these animals won't go to. Liz sets out to see these animals in action, revealing the science behind their extreme behaviours. She meets the sloth whose disgusting hygiene habits may help hide it from predators, the stone martens who cause millions of pounds' worth of damage to cars to protect their territories and the chimpanzees who use bullying tactics to get to the top. As Liz discovers, when life in the wild gets tough, this outrageous behaviour could just be the key to survival.
As the first animal to be domesticated, pigeons have a story to tell. A drama filled, steeped-in-history, amazing story. Although they’ve faded into the background of city life, pigeons have made an incredible contribution to human history. For centuries, we relied on them for everything from food, to vital communications, to entertainment to modern day brain science. They deserve more respect! The ones you see on city streets today are the descendants of domestic birds. Their gritty urban lives are spent trying to evade all manner of perils…and… stay one step ahead of starvation, a constant threat. To survive where they’re not wanted, pigeons rely on a combination of charity from a few and their own incredible smarts…. In a series of fascinating experiments and carefully placed cameras, we take you inside their perilous world; in the air, on the street and in the nest. One of the first things to notice is just how incredibly smart they are.

The team deploys underwater robots and state of the art submersible vessels for a world first - to find and film the impossible.
