How owls work: silent wings, turning heads, pellets and owl myths, sentence 2
Its huge eyes are fixed tubes that cannot roll, so the owl turns its whole head instead, about three quarters of a circle, thanks to 14 neck bones and clever blood vessels that keep the brain fed.
Who acts: huge eyes, fixed tubes, owl, clever blood vessels, brain · What happens: fix, be, not roll, turn, keep, feed · To what, where: fixed tubes, whole head, brain
