How Bees Navigate

Honeybees travel surprising distances to find flowers, yet they rarely get lost. To orient themselves, they rely on the sun as a moving compass, tracking its position across the sky even when clouds hide it by reading patterns of polarized light. When a forager discovers a rich patch of blossoms, it returns to the hive and performs a waggle dance, a looping movement whose angle encodes the direction of the food relative to the sun and whose duration signals the distance. Nestmates feel these vibrations in the dark hive and translate them into flight instructions. Remarkably, bees also build mental maps of landmarks, so an experienced forager can take shortcuts it has never flown before. This blend of celestial and local cues makes the hive an efficient gatherer of scattered resources.
