I’m sure all of you would agree that it is not easy to sleep while walking. Are you surprised to hear that some birds sleep while flying? I’m pretty sure you are. Great frigate birds is one of species who has this skill. You must be wondering how they do not crash into each other when they are sleeping in their flight. Like dolphins they just let one half of their brains sleep and keep the other half awake, allowing them to keep one eye open to watch out for predators and other birds.
