Is It Really True That Owls Can Turn Their Heads Completely Around?
When one of our nocturnal friends spins to look at you imperiously without moving its body, it can look like the head could keep on twisting indefinitely. But though an owl’s rounded neck vertebrae make it extremely flexible (and it has 14 of them to our 7), the maximum movement is 270 degrees in either direction. Any more than that and it would break its neck. Much to the delight of any passing mice, no doubt.
