Some land birds, such as vultures and certain hawks, sustain flight for long periods without flapping their wings. They take advantage of updrafts produced when the wind blows over hills and mountain ridges or make use of rising columns of warm air called "thermals." Vultures stay within thermals by flying slowly in tight circles. They have short, broad wings and a low wing loading (ratio of bird weight to wing area) that allows them to remain aloft and to be highly maneuverable at slow speeds. They also have a low aspect ratio (ratio of length to width of the wing), something that is dictated by their takeoff requirements. Low-aspect-ratio wings generally produce a lot of drag -- that is, resistance from the air through which they are moving. Air from high-pressure areas beneath the wings tends to flow over the wingtips into the low-pressure areas above the wings. That flow produces wingtip turbulence, drag-creating disturbances of the smooth flow of air. A low-aspect-ratio wing, important for maneuvering, nevertheless creates a great deal of drag, something that is very undesirable in a soaring bird.

Vultures alleviate this problem slightly by flying with their primary feathers extended, creating slots between them. Each primary serves as an individual high-aspect-ratio wing, reducing wingtip turbulence and lowering the stalling speed of the wing so that the bird can remain aloft at a slower speed. This helps vultures to circle perpetually in thermals, maintaining thrust by gliding downward, but staying aloft by sinking at a rate slower than the hot air is rising. .
