Which function disrupts bird flight when flight feathers suffer significant degradation from feather mites?

💡 Explanation

When feathers degrade from mites, aerodynamic surfaces roughen, reducing lift and increasing drag because interlock between feather barbules fails, leading to loss of flight stability. Therefore reduced stability and control result, rather than lift, insulation, or airflow which require intact feather structures.
