John, I think your conclusion makes a lot of sense. This may or may not be relevant but the mechanism for how this works may have to do with flight speed (rapidly accelerating on exit, rapidly decelerating on return) and how that relates to bee vision, as discussed in the JEB article here. An interesting experiment would be to incrementally move the hive closer and farther from the fence to see at what point the behavior changes. I recently read somewhere, I forget where, about somebody that was doing the same thing to create a bee-safe zone in front of their hives so the flight path wouldn't be at the same level as the people-walking path. If I remember correctly, they used a regular ol' chain link fence as a screen, and it worked perfectly to deflect the exiting bees in exactly the way you've described. They didn't mention the behavior of returning bees, making me wonder if the distance from the fence (and its affect on speed/vision) is the critical factor there. If I recall, their fence was about 10 feet from the hive entrance. I wonder if folks who keep bees in the mountains using bear
fences have any observations on this topic. On 11/24/2016 12:15 PM, John Rintoul
