The Great Butterfly Hunt tells the story of incredible journeys. The first is that of the remarkable Monarch migration, which is the longest insect migration on Earth, is. The second story is that of Fred Urquhart, the determined Canadian scientist who spent 40 years trying to discover exactly where the butterflies mysteriously disappeared when they flew south for the winter. The Great Butterfly Hunt is a beautiful and colourful one-hour program that combines the spectacular visuals from Flight of the Butterflies with the production’s behind-the-scenes look at how such films get made. On Thursday, January 2, when many Canadians will be groaning about the long grey winter ahead, The Great Butterfly Hunt will remind audiences of the promise of spring. And, at a time when the monarch population is in rapid decline, viewers will have an opportunity to watch one of Nature’s most dramatic feats unfold.

Within the quiet confines of your home, wild things are afoot. The great struggle to survive, the drama of life and death, the cold calculation of the hunter and the anxiety of the hunted and it goes on all around you. In the Great Indoors, every corner is a potential lair, every carpet a dense forest, and the wide spaces of your kitchen, an open savannah where the food is abundant, but so is the danger. A number of creatures fly in and get trapped; others may enter to dine and dash, but some will be found nowhere else but safe and sound at home in your home. So when you trap that house spider and decide to set it free outside, you may in fact be dooming it to death in a world it's never known.

The series starts in North Africa, where two of the world's biggest predators once battled for supremacy. At 13m and seven tonnes, the carcharodontosaurus was a huge beast, a gigantic lizard-like carnivore with shark-like teeth over six inches long. It was an efficient hunter that would slash at its prey until it bled to death. But the discovery of an upper jaw in Morocco revealed an even bigger carnivorous killer - spinosaurus. Four metres longer than Tyrannosaurus rex, spinosaurus is thought to have been one of the biggest killers to ever walk the Earth. But unlike the meat-eating carcharodontosaurus, spinosaurus mainly ate fish, living and hunting almost exclusively in the water. Like all predators that share an environment, the two may once have had to compete for food. Planet Dinosaur takes a look at what one such deadly battle may have looked like and finds out which giant beast would have been most likely to survive a fight to the death.
