Which outcome occurs when thermal updraft strength weakens during hawk soaring?

💡 Explanation

When thermal updraft weakens, hawks experience decreased lift which negates sustained soaring requiring the hawk will transition via flapping flight because maintaining sufficient airspeed becomes difficult. Therefore powered flapping increases is likely, rather than angle decreases, conservation, or tail compensations which address differing aerodynamic needs.
