Which risk increases when vulture wing feather barbules unsnap during soar?

💡 Explanation

When barbules unsnap, airflow separates from feather vane because interlocking structures maintaining aerofoil curvature are compromised, increasing turbulence and induced drag. Therefore induced drag increases, rather than lift loss, thermoregulatory failure, or muscle fatigue, mechanisms that require extensive feather damage or altered metabolic rate.
