Honeybee drones around a radio-controlled drone

Best viewed full screen, this video was very kindly supplied by Charlotte and partner whom I met on Greenham Common on 4 July 2016. I was searching for a Drone Congregation Area with a honeybee pheromone. Obviously a pheromone isn't required -- perhaps a radio-controlled drone will do the trick! This radio-controlled drone had an on-board camera.
