Fig. 2. The effect of varying tunnel length and orientation on the percentage of waggle loops of bees returning to the hive after feeding inside the tunnel. Values are means ± s.d. for each experimental condition. The proportion of waggle loops varies consistently with tunnel length, but not with tunnel orientation. Abbreviations: 4m, 4 m tunnel; 6m, 6 m tunnel; h, horizontal tunnel; o, oblique tunnel, 48° incline; v, vertical tunnel.
