Which risk increases when feather barbules of a bird become misaligned by contaminants?

💡 Explanation

When barbules misalign, the interlocking structure that maintains aerofoil shape breaks down because normal cohesive forces are disrupted, leading to turbulent airflow and decreased lift control. Therefore reduced flight maneuverability results, rather than parasite susceptibility, insulation issues or UV damage, which depend on different structural traits.
