Check out this extraordinary video of a B-2 Spirit undergoing wing flutter testing in the ‘90s. In simplest of words, the air flowing over the wing can/does induce periodic vibrations in the wing structure, if the vibrations start to match the natural frequency of the wing structure, you get flutter. If flutter is unchecked, meaning the periodic force continues to increase the amplitude of the vibration present, the wing structure will eventually break. Dangerous but a pretty cool phenomenon. |

Why macaws do the little shoulder-raise / wing-flick That tiny “shoulder lift,” half-wing flip, or soft flutter is a micro-signal in parrot body language. It’s subtle but very meaningful, and it shows up most when they are: focused emotionally regulated interacting gently with babies or trusted humans training or performing a task that requires precision (like retrieval) It’s a cluster of neurological, social, and physical cues happening all at once. 1.
