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.

After the Permian period, the epic saga of evolution and extinction on Earth produced the world's first dinosaurs, plesiosaurs and pterosaurs. They dominated land, sea and air until another period of extreme volcanism generated vast waves of lava and toxic gas and killed roughly 75% of all species.

In a remote corner of southern Arabia one mountain range holds a remarkable secret. Swept by the annual Indian Ocean monsoon, the Dhofar mountains become a magical lost world of waterfalls and cloud forests filled with chameleons and honey-badgers. Off-shore rare whales that have not bred with any others for over 60 thousand years and green sea turtles come ashore in their thousands, shadowed by egg-stealing foxes. Heat-seeking cameras reveal, for the first time ever, striped hyenas doing battle with Arabian wolves. Meanwhile local researchers come face-to-face with the incredibly rare Arabian leopard.

Patrick follows the grizzly bears that are taking a risk with the weather by leaving their winter dens early. Hungry wolves are struggling to bring down their elk prey in the unusually shallow snow. And for great grey owls, it is the iciness of the snow that is hampering their hunts. Yellowstone's winter is always one of the most brutal on the planet. But 2016 saw weather records broken, and the wildlife was forced to adapt to survive. Kate Humble gets to grips with the science behind this remarkable season, from understanding the importance of the snowpack's structure as the melt begins to uncovering why Yellowstone's unique geology poses problems for some grazer's teeth.
