Which flight characteristic decreases when a parrot's flight feathers degrade?

💡 Explanation

Reduced feather integrity decreases lift because airflow becomes turbulent across the wing during flight; this reduces aerodynamic efficiency. A decrease in lift/efficiency occurs rather than elevated metabolic demand, therefore parrots compensate with increased flapping rates.
