The petrel gives up. He knows when he's defeated.There are always other meals to be had.Accompanied by their rescuer, the emperors continue their journey to the sea.At the rockhopper colony, the chicks' big day has arrived.They all react to the same desire to explore the world beyond the colony.Like the Humboldts, the chicks join adults making a trip to the sea.They don't know it yet, but they're making a one-way journey.The rockhopper chicks have none of the Humboldt's fear,They're built to leap down cliffs. But at this age, they can't jump back up again.Like their parents, they're as tough as they come.They take scrambling down rocks in their stride, but a strange sight stops them in their tracks.
