← Nature & AnimalsWhich outcome occurs among migrating birds experiencing excessive wing loading during headwinds encountering thermal updrafts?
A)Increased reliance on powered flapping✓
B)Enhanced efficiency of active soaring
C)Decreased energy expenditure over distance
D)Reduced sensitivity to vertical turbulence
💡 Explanation
Increased wing loading demands greater lift; therefore, if headwinds require climbing using thermals, powered flapping becomes necessary because reliance on buoyancy and pure soaring is insufficient, rather than providing improved or maintained positional control.
