S29E11 Outback Pelicans

With a skeleton so light it seems almost weightless and a wingspan stretching beyond eight feet, the Australian pelican is a master of the skies, capable of flying through the day and far into the night. Yet, the true mystery lies not in its endurance, but in the forces that set it aloft. What invisible signals call it to travel? How does it navigate across vast, featureless horizons? These are the puzzles that scientists are only just starting to piece together, and NATURE is on the hunt for the answers.
