DO BIRDS SLEEP?

Birds sleep, but they have a unique ability to decide whether to keep half of their brain awake or let the whole mind go to sleep. Under risky circumstances, birds sleep with one eye open to protect themselves from predators. Birds direct the part of the brain that is awake to the peeping eye so that they can quickly get away when a predator approaches.

According to CNN, birds can control wakefulness and sleep in different parts of the brain at the same time. Interestingly, birds such as swifts that spend most of their time on the wing sleep while in flight and are not blown off course by wind currents.
