Which consequence results when owls' feather barbules lack the hooklets found in other birds?

💡 Explanation

When owls lack hooklets on their feather barbules, the feather edges become serrated because the interlocking mechanism is missing, disrupting airflow and reducing noise during flight for silent prey capture. Therefore, quieter flight results, rather than waterproofing, maneuverability, or wear reduction, which all depend on intact feather structure instead.
