Can an owl turn its head all the way around?
Owls cannot turn their heads all the way around. They can, however, turn their heads an impressive three quarters of the way around. This, combined with very rapid head movement sometimes gives the illusion they have turned their heads all the way around. They turn their heads because there is no room in their heads for eye muscles and must move their heads to change their field of view. They are able to accomplish such head movement due to an “extra” vertebra in their necks.
