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.) https://twitter.com/i/status/1223935367193092096 Link to comment Share on other sites More sharing options...

Yenn Posted February 3, 2020 Share Posted February 3, 2020 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. Link to comment Share on other sites More sharing options...
