Which mechanism causes increased avian soaring efficiency from slotted wingtips present in some bird species?

💡 Explanation

When soaring, slotted wingtips act to diminish induced drag because the slots break up and diffuse the wingtip vortex, reducing downwash and conserving energy. Therefore minimized induced drag results, rather than higher turbulence, pressure equalization, or laminar flow enhancement which have different aerodynamic requirements.
