Scientists' animal navigation experiments with bees and pigeons have initially revealed the secrets of navigation of these two animals. Frish, a famous Nobel Prize winner and Austrian biologist, measured the basic navigation ability of bee peak with a series of experiments in the 1940s, which proved that bees usually use the sun as a compass to navigate, and pointed out that bees used the sun as a reference point to tell other bees how to "dance" to reach the flower source they found.
