Magellanic penguins (Spheniscus magellanicus) looking to save some energy on their 1,200-mile-long journeys may have tapped into using one of the ocean’s most dynamic forces for help. The sea birds can sense shifts in currents and use it to maximize their efficiency by alternating their travel routes. The birds travel long distances without any visual landmarks to find food and then go back to their colonies to feed their chicks. While swimming this way increased the travel distance, staying with the direction of the current saved some energy. Under strong currents, the penguins still generally aimed towards the colony, but may have altered their direction to compensate for the forces of the current.
