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.

This programme, narrated by Andrew Scott, celebrates the glorious nature of summer on Earth and the extraordinary ways animals and plants rise to the challenges it brings. With the sun shining and the flowers blooming, this is the season of splendid abundance, and the long hours of daylight make life burst out in a riot of activity. But you have to find clever ways to get your share of the good times while they last, and as temperatures soar, everything has to deal with sweltering heat. For a whole range of animals, from sneaky ring-tailed lemurs to battling ibex, and from overheated penguins to astonishing colour-changing lizards, summer is a time when the living is not always easy.

Sir David Attenborough tells the stories of the world's best animal architects. There are house-proud bower birds, who only find a mate if they decorate their homes perfectly. There are hornets, who build electric central heating systems, and the star-nosed mole, whose house is designed so well that worms, his favourite meal, literally drop in for dinner. From larders to nurseries and from high-rises to subway systems, Attenborough shows that the animal architects have designed it long before humans.

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.
