Which risk increases when flight feathers on a soaring bird lose barb interlocking function?

💡 Explanation

When barb interlocking fails, air flows through the feather because cohesion is lost leading to turbulence, disrupting laminar flow and causing boundary layer separation and decreased lift coefficient. Therefore lift loss increases, rather than drag, ventilation or metabolism changes, which relate to other avian functions.
