Who doesn't love a good David Attenborough nature documentary? Nobody, that's who. The first episode in this new series demonstrates how leopards use stealth and concealment to get close to their prey, while African wild dogs have to work as a team. The programme also features footage of killer whales, which rely on their intelligence, Nile crocodiles that can wait years between meals, spiders able to spin 25 foot webs and amur falcons, which travel 16,000 miles every year to hunt insects. Mad, Ted.
