Which adaptation increases soaring efficiency when thermal updraft strength decreases mid-flight for rapt птицы?

💡 Explanation

When thermal updraft weakens, birds need higher lift; increasing total wing surface area reduces wing loading (weight/area) enhancing lift generation through improved airflow, becoming more responsive at lower speeds. Therefore increasing wing area results, rather than tail adjustments, air sac changes or blood flow control which manage stability, ventilation and maneuverability respectively.
