Which consequence results in soaring birds when asymmetrical air flow stalls feather sections?

💡 Explanation

Asymmetrical airflow induces differential drag and lift, stimulating uneven pressure: this provokes torque generation called aerodynamic torsion involving stalling the feather sections. Therefore, disruptive wingtip vortices form, rather than lift increases, because feather sections generate lift independently based on attack angle and direction.
