Which outcome occurs when a soaring bird’s alula feathers stall before other primaries?

💡 Explanation

Boundary layer separation occurs because the alula's stall initiates turbulent flow promoting premature loss of lift; a process called flow disruption, therefore delaying stall is crucial rather than avoiding parasitic changes or improving cross ventilation.
