There’s an old saying to sleep with one eye open. Have you ever watched a duck sleep?
You will find that often their head will be tucked in their wing, one eye closed, one eye opened. Believe it or not, they are actually asleep. Duck’s brains are split in half with one half controlling one eye and the other half controlling the other eye. So it is entirely possible for them to “turn off” half their brain to rest it while the other half remains alert for predators. Ducks will usually only fully rest both halves if they are in a large group or safe in their house where others can be on the look out.
