How soaring and gliding birds such as vultures use air currents in their fight?

Soaring and gliding birds like vultures utilize air currents, such as thermals and updrafts, to conserve energy while flying long distances. By circling in rising columns of warm air, they gain altitude without flapping their wings, allowing them to cover vast areas in search of food. This efficient use of air currents enables them to spend more time hunting and less time expending energy on flight. Their keen eyesight allows them to spot potential thermals from great heights, optimizing their foraging efforts.
