“Outback Pelicans” looks into the mystery of a mass-migration of pelicans to the Australian outback, one of the driest places on the hottest and driest continent on the planet. In years of heavy rainfall, dried-up river beds fill with water and flow inland to create an oasis in the scorching heart of the desert. Abandoning the sea, pelicans leave their coastal homes and journey more than a thousand miles inland to Lake Eyre to feast on an abundance of fish and brine shrimp. The bounty of the lake provides a perfect place to breed and raise their families, even in the middle of one of the most inhospitable places on Earth. But much about their lives and their journey remains a mystery that researchers are only now beginning to unravel.
