Honey Bees dance when they are directing their fellow bees to a certain location, for example locations where food can be found or a new home. This is known as the waggle dance. There was a study done where the only source of food for a colony was placed on the far side of a mountain. The bees could not fly over the mountain. But, when they communicated where the food was to be found, they used the angle across the mountain relative to themselves to get to the food. More studies have shown that bees have the ability to take into account the roundness of the earth and they include this information is their waggle dances.
