Episode Information

This two part series follows the Spring and Autumn seasons. The spring air has lost its winter chill. For many animals it is the end of a long siesta. Torpor and hibernation are two of nature’s most ingenious ways to cope with changes in climate, food supply and energy. Groundhogs make their way through the last snows; sleepy frogs execute their first careful moves and brown bears spring-clean, removing fallen branches from the entrances to their dens to clear the way for young and old. It’s a giant leap back to life. Autumn’s effects are inescapable: it is the season with the most enduring influence on the inhabitants of the world’s temperate climate regions. The changes to nature autumn causes manifest themselves in a myriad of different ways, from the explosion of colour of North America’s Indian summer to the blood-curdling mating cries of Tasmanian devils.
