← Nature & AnimalsWhich event happens when a bird's wing loading exceeds its species-specific threshold?
A)Altered flapping frequency for lift
B)Increased reliance upon tail rudder
C)Suppressed feather erection timing
D)Premature stall during slow flight✓
💡 Explanation
When a bird's wing loading exceeds its threshold, boundary layer separation intensifies due to an increased angle of attack to maintain lift, causing premature stall formation. Therefore premature stall results, rather than compensation solely via frequency altering, tail adjustment, or feather angle suppression, which become insufficient to counteract extreme conditions.
