← Nature & AnimalsWhich risk is magnified when a bird dynamically adjusts wing loading during sharp turns?
A)Spinal stress from counter-torque✓
B)Feather detachment exceeding tensile strength
C)Metabolic demand surpassing aerobic capacity
D)Visual acuity degradation through motion blur
💡 Explanation
When a bird executes sharp turns using dynamic wing loading, asymmetrical forces generate substantial counter-torque, requiring strong spinal stabilization because of uneven muscle activation. Therefore risk of spinal stress increases, rather than feather detachment, metabolic deficits, or blurred vision, which result from very different biomechanical stressors.
