← Nature & AnimalsWhich change occurs in soaring birds when wing loading increases due to temporary fat storage?
A)Reduced reliance on thermal updrafts
B)Decreased maneuverability for vortex exploitation✓
C)Improved ability to utilize orographic lift
D)Enhanced dynamic soaring at higher speeds
💡 Explanation
Increased wing loading causes a reduction in maneuverability because induced drag rises during turning, which dominates the trade-off for energy expenditure; therefore birds are less able to exploit tight thermal or wind gradient vortices, rather than improve soaring conditions.
