I participated in an interactive falconry demonstration, using a Harris hawk. These creatures can maneuver with incredible precision in extremely tight spaces. It's not surprising to me to see their behavior described like this, with terms from modern control theory.

Watch this, for example: https://m.youtube.com/watch?v=HYGz32iv1vw

They can fly through spaces barely wider than their body (pulling their wings in as tightly as necessary, then immediately unfolding them to continue flying), over a wide range of pitch/roll, while following a curved trajectory, while pursuing prey.

Can you imagine writing software to do that?
