Season 1 - Episode Guide

Who are Nature's brightest brainboxes? How do you measure an animal's IQ? Some species seem to have a greater mental capacity than others, but what's driven them to evolve such intelligence?

We meet the chimps with a better memory than us, cuttlefish that plan ahead, and bees that can count and play football. It's not necessarily the biggest brains that win out but the ones that are engaged most efficiently - to solve problems, remember information and use tools.

Chris Packham reveals the cleverest animal communicators on the planet and learns how scientists are using cutting-edge technology to understand their conversations.

Chris reveals some of the best building animals in the world - a group that is incredibly varied, including everything from beavers to bees and prairie dogs to bowerbirds.

Chris Packham looks at social intelligence in the animal kingdom and finds out why it is that, for animals, being together means being clever. He looks at how lions hunt in teams and each hold a very specific position, how vampire bats build trust and donor networks through grooming, and how wild wolves first became domesticated and transformed into man's best friend.

Chris Packham reveals that deceit is rife in the natural world – from cunning masters of disguise and sneaky thieves, to kidnapping otters and even femme fatale fireflies

Chris discovers the cleverest animal travellers and how they find their way, from deer with mental maps, blue whales planning routes, and dung beetles navigating by the stars.
