Owls cannot swivel their eyes, so their peripheral (side) vision is not good, and they cannot see behind them, except when they turn their head.
To compensate for their limited eye movement, owls move their whole head around to see behind them.
However, owls do not turn their head around full circle (360 degrees). What do they do instead?
Instead, owls move their head to the left, all the way to the back (between 180 and 270 degrees), or to the right, all the way around to the back.
