(a, b, c) Consecutive orientation flights of three bees. (d, e) Complete orientation phase before the first foraging flights (FO) of two bees. The squares mark the positions of tarps lying flat on the ground. The black arrows along the flight tracks of the foraging flights give the outbound direction of the flights, and the grey arrows the direction of the inbound flights. The squares on flight paths are the positions given by radar (usually every 3 s). From: Degen et al., (2015) https://doi.org/10.1016/j.anbehav.2014.12.030
