Which outcome predictably occurs when avian flight feathers experience excessive bending during high-speed flight?

💡 Explanation

When flight feathers bend excessively, the laminar airflow deflects disrupting surface adhesion triggering turbulent generation behind feathers, decreasing upwards force from the wing. Therefore reduced lift results due to flow separation, rather than changes in drag or maneuverability that are caused by control surface geometry shifts with airflow.
