Which mechanical outcome arises when a raptor's flight feathers experience excessive barb separation?

💡 Explanation

When barbs separate excessively, air flows through the feather structure, disrupting the smooth airflow over the wing because turbulence increases due to loss of aerodynamic integrity, increasing form drag. Therefore, lift is reduced, rather than improved glide/soar, rate compensation or maneuverability, as these rely on smooth feathers and airfoil characteristics.
