Which consequence results when birds undergo prolonged exposure to air pollution reducing feather barbule adhesion?

💡 Explanation

When air pollution reduces feather barbule adhesion, airflow leakage around the feather increases decreasing the wing's lift profile because aerodynamic efficiency relies on linked barbules forming a continuous lifting surface. Therefore, decreased flight efficiency results, not thermoregulation, escape reflexes, or call range, which depend on other mechanisms.
