Which risk increases when feather barbules on a bird's wing become misaligned during prolonged flight?

💡 Explanation

When barbules misalign, airfoil shape degrades because aerodynamic control relies on interlocked barbules forming a continuous, smooth surface to maintain laminar airflow, decreasing lift generation. Therefore, reduced lift results, rather than dehydration, shivering, or predator detection which depend on thermal regulation or camoflage mechanisms.
