Researchers tracked honey bees in the wild using a drone-based system and found that each bee follows its own highly consistent flight path. Some repeated their routes so precisely that they flew only centimeters from where they had flown before. Landmarks like trees helped keep them on track, while uniform areas such as cornfields led to more variation.
The study was led by neurobiologist and behavioral biologist Prof. Dr. Andrew Straw, whose team used a drone to monitor honey bees traveling between their hive and a food source located about 120 meters away in an agricultural setting.
To track the insects during flight, the researchers used a technique called 'Fast Lock-On (FLO) Tracking', developed by Dr. Straw's research group. The method involves attaching a tiny reflective marker to each bee. A computer mounted on the drone analyzes reflected light and can identify and track a bee within milliseconds as it flies.
The researchers analyzed 255 flight paths collected near Kaiserstuhl, Germany. The study area included hedges, a cornfield, and a tree that stood between the hive and the food source, preventing a direct route.
Said Straw:
"We found a high degree of precision in the flight paths. Individual bees repeated their individual flight paths nearly exactly on several flights. They often fly just a few centimeters away from their previous paths.
Our results suggest that visual landmarks aid the bees' navigation and increase the precision of their flight paths."
The most consistent flight behavior occurred near prominent landscape features, particularly trees. The greatest variation appeared when bees flew above a cornfield, where the scenery offered fewer distinct visual cues.
