I recently learnt that owls have really long necks! They have 14 vertebrae compared to our 7. This allows owls to turn their heads 270 degrees, tilt their heads 90 degrees, and bob their heads up and down without moving their shoulders. This is really useful for them since they have tube-shaped eyes that are locked in place by bony sclerotic rings. They can't roll their eyes like us but can move their whole head to see what's around.
