The owl can rotate its head up to 270 degrees. This remarkable movement helps an owl survey its surroundings and see behind itself while keeping its body still, an advantage when hunting at night.
Owls cannot freely move their large, tube-shaped eyes inside their sockets, so they turn their heads instead. Their necks contain 14 vertebrae, twice the number found in humans. Specialized blood vessels and unusually roomy openings in the vertebrae help maintain blood flow to the brain during rotation.
The 270-degree figure describes the total range of head movement, not a full 360-degree spin. Owls cannot rotate their heads completely around, and the movement does not mean the neck is twisting in the same way a flexible human neck might. Their forward-facing eyes provide excellent depth perception, while the facial disc helps funnel sound toward the ears. Silent flight, strong talons, and sensitive hearing complete the owl's nighttime hunting toolkit.
