Gaze following in pigeons increases with the number of demonstrators.

Although we found some indications of gaze following in this experiment, the difference between test and control conditions did not reach statistical significance (likelihood of looking: χ 2 (1) = 1.848, β = 0.443, p = 0.174; Figure 2 A; see Table S2 for more details; observers’ number of looks: χ 2 (1) = 2.006, β = 0.335, p = 0.157; Figure 2 B).
