Swarm: Nature's Incredible Invasions

When Worlds Collide (1x1)

Fecha de emisión: Ene 04, 2009

The first programme in a two-part documentary reveals the awe-inspiring world of animal swarms. We discover what happens when superswarms invade our lives and, using the latest camera techniques, we go to the heart of the swarm, to reveal how the creatures view our world. Real-life footage from camcorders and mobile phones captures the amazing impact they can have on our lives. Killers bees mount an attack on an international football match in Costa Rica, while in the US the Illinois River literally boils with leaping silver carp, an alien species that has hijacked the river smashing into boats and injuring people. In South Australia a sea of mice raid farms as millions consume and destroy on a scale that defies belief. The largest swarm on Earth erupts from Lake Victoria, trillions of flies blanket villages, but the locals have learnt to turn this swarm into a highly nutritious fly-burger. In Rome, cameras fly alongside ten million starlings, the largest swarm in Europe. Their mesmeric waves stop many residents in their tracks, but as they roost they smother the city in tons of excrement. One man has learnt to control the ultimate swarm, he has become their 'queen bee' with startling results, learning to control what most people fear, and to understand one of the most incredible forces of nature.
