So I’m order to see as well as they do, owls’ eyes are cylindrical (unlike ours, which are spherical). This means that they can’t swivel their eyes, as there just isn’t space in the skull.

As a result, they’ve evolved to be able to turn their heads a long way.

That’s the why – as for the how, they have more neck vertebrae than we do, which allows for a greater degree of rotation.
