An owl's seeming ability to rotate its head in a complete circle is downright eerie. An owl's apparent head rotation is part illusion, part structural design. Because its eyes are fixed in their sockets, it must rotate its neck to look around. It can actually rotate its head about 270 degrees – a marvelous anatomical feat. You can learn more about this Eastern Screech-Owl at Cornell's AllAboutBirds.
