Scientists used a drone to track honey bees and found that each bee has its own unique flight path. They use landmarks in the landscape to navigate and are very accurate.

Honey bees are more precise navigators than we thought. Researchers at the University of Freiburg discovered that individual honey bees follow their own consistent flight routes and can repeat them with remarkable accuracy. The study was led by neurobiologist Prof. Dr. Andrew Straw, who used a drone to monitor honey bees traveling between their hive and a food source located about 120 meters away in an agricultural setting.

The researchers developed a technique called 'Fast Lock-On (FLO) Tracking' to track the insects during flight. They attached a tiny reflective marker to each bee and used a computer mounted on the drone to analyze reflected light and identify and track the bees within milliseconds as they flew. The observations revealed that each honey bee follows its own preferred route and maintains that path with exceptional accuracy on both outbound and return trips.

The bees also appear to use features in the surrounding landscape to help guide their journeys. The study analyzed 255 flight paths collected near Kaiserstuhl, Germany. The area included hedges, a cornfield, and a tree that stood between the hive and the food source, preventing a direct route.

The researchers found a high degree of precision in the flight paths. Individual bees repeated their individual flight paths nearly exactly on several flights. They often flew just a few centimeters away from their previous paths.

Why It Matters

This study shows how clever and precise honey bees are. It also helps us understand how they communicate with each other, which can help us improve our own navigation systems.

Key Facts

• Honey bees have their own unique flight paths that they follow with remarkable accuracy.
• They use landmarks in the landscape to navigate and guide their journeys.
• Each bee has its own preferred route and maintains that path with exceptional accuracy on both outbound and return trips.
