Birds sleep without falling off



More facts...Today is about birds sleep without falling off.










Birds do not fall down when they sleep on a branch, their toes automatically snuggled in tight to secure them on the branch, so they cannot fall while asleep.





Besides, birds are light sleepers. They must be constantly aware of their surroundings, keeping an ear alert for danger, ready to move on at a moment's notice.
