← Nature & AnimalsWhich outcome directly diminishes lift effectiveness due to structural failure of avian air sacs during rapid bird ascent?
A)Decreased wing camber during upstroke✓
B)Elevated feather pitching oscillation index
C)Reduced buoyancy altering flight profile
D)Altered center gravity decreasing torque
💡 Explanation
When air sacs rupture during ascent, deflation reduces wing camber, impairing aerodynamic profile because maintaining curvature generates lift during feather upstroke. Therefore decreased wing camber arises, rather than pitching, buoyancy or balance changes which are driven by differing system controls.
