Method Wenner (primary source) timed the flights of honey bees flying outdoors from their hive to a feeder. He concluded that the cruising speed of unloaded honey bees in natural outdoor environments is ~7.5m/sec, and that this value changes very little even in the face of headwinds or tailwinds as large as 3m/sec.
Comments (primary source abstract:) Regression lines gave ground speeds of 7.5 and 6.5 m/sec respectively for unloaded and loaded bees, the difference being significant (p < 0.001) in neutral winds these speeds were 7.8 and 7.0 m/sec respectively.
