SAILOR DUCK

Ducks are truly extraordinary creatures. They can put half their brain to sleep while the other half stays alert for predators — a skill called unihemispheric sleep. Their eyes are placed so wide on their heads that they can see almost everything around them simultaneously, like a natural radar system. They spread a special oil across their feathers while preening, making them completely waterproof — a duck can dive into water and come out perfectly dry. And when it's time to migrate, they travel thousands of kilometres with remarkable precision, guided by the sun, the stars, and Earth's own magnetic field. 🦆
