Natural Visual Stabilization

Natural selection builds mechanisms that human engineers still struggle to match. Exhibit A: The neural structures underpinning head stabilization in this hawk. (Head stabilization has the same function as image stabilization in cameras: to maintain a steady view despite motion.)

The alternative to closing the eyes when they take a step is to hold the head in one place as the body advances under it with each step. Just watch birds walking with the head moving forward when the body is still.
