Which biomechanical outcome results upon excessive feather barbule separation in hummingbird flight?

💡 Explanation

Feather barbule separation increases air permeability, disrupting the airfoil. This reduces the lift generated with each wing stroke because aerodynamic lift critically depends on sustained surface pressure differentials, therefore the stall angle decreases, rather than remaining steady, leading to unpredictable stalls.
