Figure 4. Flight path of non-returned bees.

Graphical representation of all recorded flight paths of non-retuning bees and the spatial distribution of the final bee positions (C_S: double black line, white diamonds, end-position = white cross; C_GE: grey line, light grey markers, end-position = grey cross; Nc: black line, black markers, end-position = black cross). The release site is located at the origin of the axes and the hive position indicated by the white arrow. The grey circle illustrates the 60 m perimeter at which track heading direction was assessed and which is illustrated in the inserts (black arrow: overall mean heading direction).
