Epic Animal Migrations Patagonia

S1 E1: Patagonia is a land of absolute contrast, of calm and gale, light and dark, ice and fire. A Landscape so dramatic and harsh that its residents are totally unique. Vicious variations in weather and temperature across its icy peaks, tundra biome, flooded wetlands and frozen oceans, mean that animals here are constantly on the move. Each year, thousands return to give birth and raise vulnerable young, while many more come home to feed and some, to hunt. For all of them, migrating across Patagonia is not a choice it's their only chance of survival. This it the story of their epic migrations.
