#1 Strange? Not For Barn Owls!
All owls can easily do the, "rotating head" trick like the scary teenage girl in the 'The Exorcist'. They don't need eyes on the back of their heads to see what's behind them! Supposedly this supernatural ability has to do with unique "vertebral arteries" in their neck, allowing blood to flow to the brain without being "pinched" or broken. Wow!
